Answer:

34 = -2

Step-by-step explanation:

20 = 7 x (5-3) = 34

(8-6) - 4 = -2

So the  answer is 34 = -2

The equation 20+7 • (5-3) = (8-6) - 4, when evaluated using the order of operations, gives the result 34 = -2, which indicates that the original equation is not balanced.

Let's evaluate the expression 20+7 • (5-3) = (8-6) - 4 using the order of operations, which can be remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

First, we solve the expressions in parentheses: 7 • (5-3) = 7 • 2 = 14 and  (8-6) - 4 = 2 - 4 = -2.

Then we perform the addition: 20 + 14 = 34. At this point, we have 34 = -2, which is not correct. Therefore, the original equation is not balanced.

Answer:

Step-by-step explanation:

In a parallelogram, the opposite sides are equal and parallel.

Also, consecutive angles in a parallelogram are supplementary. This means that the sum of the consecutive angles is 180 degrees.

Angle 2m and angle n are supplementary angles. Therefore,

2m + n = 180 - - - - - - - - - - - -1

Also, the opposite angle in a parallelogram are equal. This means that

2m = 70

m = 70/2

m = 35 degrees

Substituting m = 35 into equation 1, it becomes

2 × 35 + n = 180

70 + n = 180

n = 180 - 70

n = 110 degrees

The value of m and n are 35 and 110 respectively.

We are given that one of the angles of the parallelogram is [tex]70^\circ[/tex].

Since opposite angles in a parallelogram are supplementary, the angle directly opposite the 70° angle must be [tex]180^\circ -70^\circ = 110^\circ[/tex].

We are also given that one of the non-consecutive interior angles has a measure of 2m°.

Since consecutive interior angles in a parallelogram add up to 180°, the angle next to the 2m° angle must have a measure of 180°- 2m°.

The opposite sides of a parallelogram are congruent.

This means that n° must be congruent to 110°. So, n = 110.

We can now solve for 'm'.

Since the angle next to the 2m° angle must have a measure of 180°−2m° and this angle is also congruent to 110°.

We have the equation: [tex]110^\circ = 180^\circ - 2m^\circ[/tex]

[tex]2m^\circ = 70^\circ[/tex]

[tex]m=35[/tex]

Answer:

-429/629

Step-by-step explanation:

Use angle difference formula:

sin(x − y) = sin x cos y − sin y cos x

Assuming x and y are in the first quadrant:

sin(x − y) = sin x cos y − √(1 − cos²y)√(1 − sin²x)

Plugging in values:

sin(x − y) = (8/17) (12/37) − √(1 − (12/37)²)√(1 − (8/17)²)

sin(x − y) = (8/17) (12/37) − (35/37)(15/17)

sin(x − y) = -429/629

Answer:

y = 2x^2 - 12x + 27

Step-by-step explanation:

Step 1:  Distribute the power

y = 2(x - 3)² + 9

y = 2(x^2 - 6x + 9) + 9

y = 2x^2 - 12x + 18 + 9

y = 2x^2 - 12x + 27

Answer: y = 2x^2 - 12x + 27

Answer:

a) Rate of change of amount

[tex]A'(t) =110e^{0.055t}[/tex]

b) &170.79

c) 0.21

Step-by-step explanation:

We are given the following in the question:

The balance is given by the equation:

[tex]A(t) =- 2000e^{0.055t}[/tex]

where t is the time in years and the initial investment is $2000 when compounded continuously.

a) Rate of change of amount

[tex]\dfrac{d(A(t))}{dt} = \dfrac{d}{dt}(2000e^{0.055t})\\\\\dfrac{d(A(t))}{dt} = 2000e^{0.055t}\times 0.055\\\\\dfrac{d(A(t))}{dt} =110e^{0.055t}[/tex]

b) We have to find the value of A'(8)

[tex]A'(t) =110e^{0.055t}\\A'(8) = 110e^{0.055(8)} = 170.79[/tex]

Interpretation:

The future value of 9 year investment of $2000 will be $170.79 more than the future value of 8 year investment.

c) Comparison

Approximation = $171

Actual change = $170.79

Difference =

[tex]\text{Approximation - Actual change}\\=171 - 170.79\\=0.21[/tex]

Thus, the error is 0.21

The formula for dA/dt is 2000(0.055)e^(0.055t). A'(8) is found by substituting t=8 into dA/dt. To compare the approximation of $171 to the actual change, subtract the initial investment from the new balance after 8 years.

a. To find the formula for dA/dt, we differentiate the equation A(t) = 2000e^(0.055t) with respect to t. Using the chain rule, we have dA/dt = 2000(0.055)e^(0.055t).

b. To find A'(8), we substitute t = 8 into the expression for dA/dt. Plugging in the values, we get A'(8) = 2000(0.055)e^(0.055(8)). This will give us the rate of change of the balance after 8 years.

c. To compare the approximation of $171 to the actual change, we subtract the initial investment of $2000 from the new balance after 8 years. The approximation is $171, so the actual change is A(8) - 2000. Plugging in the values, we get A(8) - 2000 = 2000e^(0.055(8)) - 2000.

Step-by-step explanation:

He has 35.8 liters.

He uses 28.6 liters.

Now that tanks has 35.8 liters - 28.6 liters = 7.2 liters

The capacity of the tank is 42 liters, and he has only 7.2 liters.

The fill up will be 42 liters - 7.2 liters = 34.8 liters

Answer: he bought 34.8 liters of gas.

Step-by-step explanation:

Let x represent the number of liters of gas that Alberto bought.

At the beginning of the week, Alberto's car has 35.8 liters of gasoline in its tank. He uses 28.6 liters of gasoline during the week. This means that the number of liters of gas left would be

35.8 - 28.6 = 7.2

Then he completely fills the tank with gas. If the gas tank of Alberto's car holds a total of 42 liters of gas., it means that

x + 7.2 = 42

x = 42 - 7.2

x = 34.8 liters

Answer:

Step-by-step explanation:

Let x represent the constant amount by which the length and width of the garden is increased.

Tyler has a rectangular garden that measures 10 m wide by 13 m long. He wants to increase the area to 208 m² by increasing the width and length by the same amount. This means that the new length of the garden would be (13 + 2x) cm and the new width of the garden would be (10 + 2x) cm. Therefore,

(13 + 2x)(10 + 2x) = 208

130 + 26x + 20x + 4x² -208 = 0

4x² + 46x - 208 - 130 = 0

4x² + 46x - 78 = 0

Dividing through by 2, it becomes

2x² + 23x - 39 = 0

2x² + 26x - 3x - 39 = 0

2x(x + 13) - 3(x + 13) = 0

2x - 3 = 0 or x + 13 = 0

x = 3/2 or x = - 13

Since the value of x cannot be negative, then

x = 3/2 = 1.5 m

The length of the new garden is

13 + 1.5 = 14.5 m

Answer: the balance is $5328.95

Step-by-step explanation:

The formula for continuously compounded interest is

A = P x e (r x t)

Where

A represents the future value of the investment after t years.

P represents the present value or initial amount invested

r represents the interest rate

t represents the time in years for which the investment was made.

e is the mathematical constant approximated as 2.7183.

From the information given,

P = 3200

r = 8.5% = 8.5/100 = 0.085

t = 6 years

Therefore,

A = 3200 x 2.7183^(0.085 x 6)

A = 3200 x 2.7183^(0.51)

A = $5328.95 to the nearest hundredth

Step-by-step explanation:

Answer: the angle of elevation from the person on the ground to the top of the volcano is 87.7°

Step-by-step explanation:

The person, his angle of elevation and his distance from the foot of the mountain forms a right angle triangle.

The altitude of the mountain represents the opposite side of the right angle triangle.

The distance of the person from the base of the volcano represents the opposite side of the right angle triangle.

To determine the angle of elevation from the person on the ground to the top of the volcano, we would apply the tangent trigonometric ratio.

Tan θ, = opposite side/adjacent side. Therefore,

Tan θ = 3000/120 = 25

θ = Tan^-1(25)

θ = 87.7° to the nearest tenth.

From the Venn diagram,

n(B U H) = n(S' n B n H') + n(S' n B n H) + n(S n B n H') + n(S n B n H) + n(S n B' n H) + n(S' n B' n H) = 26 + 10 + 18 + 12 + 16 + 0 = 82%

P(B U H) = 82/100 = 0.82

c) The probability that a randomly selected student does not like any of these sports.

P(S' n B' n H')

n(S' n B' n H') = n(U) - [n(S' n B n H') + n(S' n B n H) + n(S n B n H') + n(S n B n H) + n(S n B' n H) + n(S' n B' n H) + n(S n B' n H')]

n(S' n B' n H') = 100 - (26 + 10 + 18 + 12 + 16 + 0 + 2) = 100 - 84 = 16%

Step-by-step explanation:

Given:

- The ratings for current lives on a scale 0 - 10 were normally distributed with parameters mean (u) and standard deviation (s).

                                   u = 5.3

                                   s = 2.5

Find:

Find the probability that a randomly selected study​ participant's response was less than 4.

Solution:

- Declare a random variable X that follows a normally distribution with parameters u and s, mean and standard deviation respectively.

                                  X~N( 5.3 , 2.5 )

- To determine the probability of the rating to be less than 4 for a randomly selected study participant's response we have:

                                  P ( X < 4 )

- Compute the Z-score value for the limit given:

                                  P ( Z < (4 - 5.3) / 2.5 )

                                  P ( Z < -0.52 )

- Use the Z-Table to calculate the above probability as follows:

                                  P ( Z < -0.52 ) = 0.3015

- Hence, the required probability is equivalent to Z-score value probability:

                                    P ( X < 4 ) = P ( Z < -0.52 ) = 0.3015

The probability that a randomly selected study participant's response was less than 4 is 0.3015.

To find the probability that a randomly selected study participant's response was less than 4, we can use the properties of the normal distribution. Given that the mean is 5.3 and the standard deviation is 2.5, we can standardize the value 4 using the z-score formula: z = (X - µ) / σ, where X is the value of interest, µ is the mean, and σ is the standard deviation. Once we find the z-score, we look up this value in the standard normal distribution table (Z-table) or use a calculator to find the probability.

The probability that a randomly selected study participant's response was less than 4 is therefore 0.3015, or 30.15% when converted into percentage form.

The answer to your question is QG = 55.8 ft

Step-by-step explanation:

Data

QG = x

Process

1.- Find T

The sum of the internal angles in a triangle equals 180°

          G  +  Q  +  T  = 180

-Solve for T

            T  =  180 - G  -  Q

- Substitution

            T = 180 - 41 - 67

-Simplification

             T = 72°

2.- Use the law of sines to find QG

              QG / sin T = GT / sin Q

-Solve for QG

              QG = GT sinT / sin Q

-Substitution

              QG = 54 sin 72 / sin 67

- Simplification

              QG = 54 (0.951)/0.921

-Result

             QG = 55.8 ft        

Answer:

Step-by-step explanation:

Considering the given triangle QGT, to determine QG, we would apply the sine rule. It is expressed as

a/SinA = b/SinB = c/SinC

Where a, b and c are the length of each side of the triangle and angle A, Angle B and angle C are the corresponding angles of the triangle. Likening it to the given triangle, the expression becomes

QG/SinT = GT/SinQ = QT/SinG

The sum of the angles in a triangle is 180°. It means that

T = 180 - (41 + 67) = 72°

Therefore

QG/Sin72 = 54/Sin 67

Cross multiplying, it becomes

QGSin67 = 54Sin72

0.921QG = 54 × 0.951

0.921QG = 51.354

QG = 51.354/0.921

QG = 55.8 ft

Answer:

496

Step-by-step explanation:

I am assuming that there are options lacking. The average score, due to the Law Of Big Numbers, using a big enough sample will be close to the mean of the random variable. Thus the mean of the average scores will be close to 496 if the process is done many times.

The mean of the average scores will be close to the population mean of 496.

The mean of the average scores will be close to the population mean, which is 496. The Central Limit Theorem states that as the sample size increases, the sample mean approaches the population mean. In this case, since we are choosing an SRS of 100 students, the mean of the average scores will be close to the population mean of 496.

Answer: B 8/5 hr

Step-by-step explanation:

One maid can clean the house in 2 hours. This means that the rate at which she cleans the house per hour is 1/2

Another maid can do the job in 8 hours. This means that the rate at which the other maid cleans the house per hour is 1/8

If they work together, they would work simultaneously and their individual rates are additive. This means that their combined working rate would be

1/2 + 1/8 = 5/8

Assuming it takes t hours for both of them to clean the room working together, the working rate per hour would be 1/t. Therefore,

5/8 = 1/t

t = 8/5 hour

Option B is correct. Working together, the two maids can clean the house in 8/5 hours.

Let's assume that the combined rate of both maids working together is x house cleaned per hour. We can set up the equation:

1 maid's rate + another maid's rate = combined rate

1/2 + 1/8 = x

Solving for x:

4/8 + 1/8 = x

5/8 = x

The combined rate of the maids working together is 5/8 house cleaned per hour. To find how long it will take them to clean the house together, we can set up the equation:

(5/8) house per hour = 1 house

Let t be the time it takes them to clean the house together. We can write the equation:

(5/8) * t = 1

Solving for t:

t = 1 / (5/8)

t = 8/5 hours.

Answer:

C) 52 in^3

Step-by-step explanation:

The first is to determine the formula of the volume of the box, which would be the following:

 V = height * length * width

Knowing that we have a rectangular piece we will determine the maximum volume, we will double a distance x (which will be the height) in the width and length of the piece, therefore as it is on both sides, the length and width are defined from the Following way:

length = 10 - 2 * x

width = 8 - 2 * x

height = x

Now we calculate the volume:

V = x * (10-2 * x) * (8-2 * x)

To determine the maximum volume we will give values to x in order to see how it behaves:

Let x = 2.5

V = (5) * (3) * (2.5) = 37.5

Let x = 2

V = (6) * (4) * (2) = 48

Let x = 1.5

V = (7) * (5) * (1.5) = 52.5

Let x = 1

V = (8) * (6) * (1) = 48

Let x = 0.5

V = (9) * (7) * (0.5) = 31.5

It can be seen that the greatest volume is obtained when the height is equal to 1.5 and its volume is 52.5 in ^ 3

Answer:

(a)His monthly Interest Rate=0.8%

(b)Annual Interest Rate = 9.6%

(c)[tex]500(1.008)^m[/tex]

Step-by-step explanation:

For a Principal P invested at a yearly rate r, compounded m times in t years

Amount at Compound Interest= [tex]P(1+\frac{r}{m})^{mt}[/tex]

Comparing with Jerry's equation y=388 (1.008)

(a)His monthly Interest Rate= 0.008=0.8%

(b)Annual Interest Rate= Monthly Interest Rate X 12 =0.8 X 12 = 9.6%

(c)If I invest $500 at the same rate of return,

Total Money after m months

= [tex]P(1+\frac{r}{m})^{mt}[/tex][tex]=500(1+0.008)^{m}[/tex][tex]=500(1.008)^m[/tex]

Final answer:

Jerry's monthly interest rate is 0.8%, and his annual interest rate is approximately 9.96%. An investment of $500 in the same account would grow according to the equation [tex]y = 500(1.008)^{m}[/tex], where m represents the months invested.

Explanation:

Jerry says he's got his money in a great account that compounds interest monthly. The equation [tex]y=388(1.008)^{m}[/tex] represents how much money he has at the end of the month. The monthly interest rate is found in the equation inside the parentheses, 1.008, which means the monthly interest rate is 0.8% (since 1.008 is equal to 1 plus 0.008 or 1 + 0.8/100). To find the annual interest rate, we need to use the compounding formula, which for monthly compounding can be simplified to [tex](1 + monthly interest rate)^{12} - 1[/tex]. so, [tex](1.008)^{12}- 1[/tex] gives an annual rate of approximately 9.96%.

To write an equation representing your total money if you invest $500 in an account with the same rate of return, we use the formula [tex]y = P(1 + r)^{m}[/tex], where P is the principal amount ($500), r is the monthly interest rate (0.008), and m represents the number of months the money has been invested. Therefore, the equation is [tex]y = 500(1.008)^{m}[/tex].

Answer: the amount of interest earned is $44.7

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the amount deposited.

P represents the principal or amount deposited.

R represents interest rate

T represents the duration in years.

From the information given,

P = $1295

R = 7%

T = 180 day. Assuming there are 365 days in a year. Converting 180 days to years, it becomes

180/365 = 0.49315 year

b). When n is even, we have a choice of any of the 26 characters for the first letter, similarly, we can choose any character for the second, and so on up till the n/2 th position after which subsequent letters depend on the letter chosen before the half point following the definition of a palindrome.

Therefore we have n/2 independent choices with repetition therefore we have [tex]26^{\frac{n}{2} }[/tex] palindromes of even length with or without meaning in the alphabet

On the other hand, when n is odd, we are free to chose any letter up to the middle letter as before this means we have [tex]\frac{n-1}{2} +1 = \frac{n+1}{2}[/tex] free choices

Therefore the number of odd length palindromes are [tex]26^{\frac{n+1}{2} }[/tex]

c). For a ternary string palindrome, we have 26 letters for the first position, and also 26 for the second, while the third is the same as the first which is one option.

Where n = 2 we have 26 ways of selecting the first and second letters which are equal

Therefore the number of  ternary string palindromes of length n  are 26×26 + 26 = 702

Bit string palindromes of length 5 and 6 are strings that are the same forward and backward, like '10101' or '100001'. The number of palindromic bit strings of length n is 2 raised to the floor of n/2, and the number of ternary string palindromes of length n is 3 raised to the floor of n/2.

A palindrome is a string that remains the same when reversed. Examples of bit string palindromes of length 5 include '10001', '01110', '10101', '01010'. For length 6, examples could be '100001', '011110', '101101', '010010'.

In general, to calculate the number of palindromic bit strings for any given length, the first half of the string can be anything (2 ⌊n/2⌋ possibilities), and the second half must mirror the first. Thus there are 2 ⌊n/2⌋ bit string palindromes of length n.

For ternary palindromes (strings composed of the digits 0, 1, and 2), use the same logic but switch the base to 3. Thus there are 3 ⌊n/2⌋ ternary string palindromes of length n.

Explanation:

The sample mean is not always equal to the population mean but if we take more and more number of samples from the population then the mean of the sample would become equal to the population mean.

The Central Limit Theorem states that we can have a normal distribution of sample means even if the original population doesn't follow normal distribution, But we have to take a lot of samples.

Suppose a population doesn't follow normal distribution and is very skewed then we can still have sampling distribution that is completely normal if we take a lot of samples.

Answer: 38 mph

Step-by-step explanation:

Add. 10 plis 28 is 38.

Answer: 19 miles

Step-by-step explanation:

Distance = speed × time

Biking at 10 mph, it takes Kristen 1/2 hour to reach the train station to go to work. This means that the distance covered on her way to the train station is

0.5 × 10 = 5 miles

Kristen then takes the train to work, and it takes another 1/2 hour for her to get to work when the train travels 28 mph. Distance covered by the train is

0.5 × 28 = 14 miles

Therefore, the distance that Kristen travels to work is

14 + 5 = 19 miles

Answer:

Linda's share was $ 1933.75

Step-by-step explanation:

We first need to calculate the comission that was paid to the other real state firm wich is 7% of the sales price, so we can use the following equation:

Comission = 85000 * (7/100) = 85000*0.07 = 5950 $

Since this comission was split in half between Johnson's broker and the other broker we have 5950/2 = 2975 for each of them. From that value 65% should stay with the broker wich is Linda in this case so:

Linda's share = 2975*(65/100) = 2975*(0.65) = 1933.75 $.

Given Information:

Sale Amount = $85,000

Commission rate = 7%

Linda Johnson commission rate = 65% of 50% of commission amount

Required Information:

Linda Johnson share in the sale = ?

Answer:

Linda Johnson share in the sale = $1933.75

Step-by-step explanation:

Linda Johnson share in the sale is

Linda's share = 65% of 50% of commission amount

Where commission amount is

commission amount = 7% of sale amount

commission amount = 0.07*85,000

commission amount = $5,950

Linda's share = 0.65*0.50*5,950

Linda's share = $1933.75

Mrs. Mathewson can serve orange juice to 4 guests. The solution was found by first converting the fractions to the same denominator, then dividing the total orange juice by the amount per guest, and taking into account that you can't serve fractions of a guest.

The problem presented here is a basic division problem that requires you to divide the total amount of orange juice by the amount served to each guest. Mrs. Mathewson has 7/8 quarts of orange juice and she would like to serve each guest 3/16 quarts of orange juice.

Firstly, we'll convert both fractions to the same denominator for simplicity. As 8 is a multiple of 16, we can leave the second fraction as it is (3/16) and change the first fraction to 14/16 (which is the same as 7/8). Now, we divide 14 by 3 which gives us roughly 4.6.

This result means Mrs. Mathewson can serve orange juice to 4 guests with a bit left over. As we can't serve a fraction of a guest, it means she can only serve 4 whole guests.

Mrs. Mathewson can serve orange juice to 14 guests.

To determine how many guests Mrs. Mathewson can serve orange juice, we need to find the quotient of the total amount of orange juice and the amount per guest. Given that there are 7/8 quarts of orange juice and Mrs. Mathewson wants to serve 3/16 quarts per guest, we divide the total amount by the amount per guest: (7/8) ÷ (3/16) = (7/8) × (16/3) = 14 guests.
