Answer:

($13,300,$46,900)

Step-by-step explanation:

We are given the following in he question:

Mean, μ = $30,100

Standard Deviation, σ = $5,600

Chebyshev's Theorem:

[tex]1 -\dfrac{1}{(3)^2} = 0.889 \approx 89\%[/tex]

Thus, 89% of data lies within three standard deviation of mean.

[tex]\mu - 3(\sigma) = 30100 - 3(5600) = 13300\\\mu + 3(\sigma) = 30100 + 3(5600) = 46900[/tex]

Thus, we expect at least 89% of new car prices to fall within ($13,300,$46,900)

Answer:

Pythagorean's theorem: a²+ b²= c²

Sines: sin A = a/c, sin B = b/c.

Cosines: cos A = b/c, cos B = a/c.

Tangents: tan A = a/b, tan B = b/a.

Step-by-step explanation:

For example, if the side a = 22 and the angle A = 41°, we can use a sine and a tangent to find the hypotenuse and the other side. Since sin A = a/c, therefore c = a/sin A = 22/sin 41. Using a calculator, this is 22/0.6561 = 33.5314. Also, tan A = a/b, so b = a/tan A = 22/tan 41 = 22/0.8693 = 25.307.

Answer: Leah has 15 stickers left for herself.

Step-by-step explanation:

Total number of stickers that Leah had initially is 50. Leah gave 1/2 of the stickers to her sister. This means that the number of stickers that Leah gave to her sister is

1/2 × 50 = 25 stickers

Of the amount left, she gave 2/5 to her friend. This means that the number of stickers that Leah gave to her friend is

2/5 × 25 = 10 stickers

Therefore, the number of stickers that Leah have left for herself is

50 - (25 + 15)

= 50 - 35

= 15

After giving away some of her stickers to her sister and friend, Leah has 15 stickers left for herself.

Leah initially had 50 stickers. She gave half of them to her sister, which left her with 50/2 = 25 stickers. Then, she gave away 2/5 of these remaining stickers to her friend.

To calculate how many she gave her friend, we multiply 25 * 2/5 = 10 stickers.

To find out how many Leah has left for herself, we subtract this from the number she had after giving stickers to her sister: 25 - 10 = 15 stickers.

So, Leah has 15 stickers left for herself.

Answer:

The answer to your question is 1.- (-3, 4)    2.-   (3, 1)  None of the choices

Step-by-step explanation:

1.- The solution of a system of equation by the graph method is the point in which the lines cross. In this graph we observe that this point is approximately

(-3, 4).

2.-

Equation 1   x + y = 4

Equation 2  x - y = 2

Solve by the combination method

                   x + y = 4

                  x  -  y = 2

                 2x    0  = 6

                        2x = 6

Solve for x

                          x = 6/2

                          x = 3

Substitute x in equation 1 to find y

                    3 + y = 4

Solve for y

                          y = 4 - 3

                          y = 1

Solution     (3, 1)                          

the equations are:

[tex]\[ c^2 = a^2 + b^2 \][/tex]

[tex]\[ a^2 = c^2 - b^2 \][/tex]

[tex]\[ b^2 = c^2 - a^2 \][/tex]

In a right triangle, according to the Pythagorean theorem, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. So, we have:

[tex]\[ c^2 = a^2 + b^2 \][/tex]

This equation represents the relationship among the side lengths of a right triangle.

Therefore, the equations are:

[tex]\[ c^2 = a^2 + b^2 \][/tex]

[tex]\[ a^2 = c^2 - b^2 \][/tex]

[tex]\[ b^2 = c^2 - a^2 \][/tex]

This completes the three relations among a, b, andc.

Answer:

She buy 0.5 pounds of black olives and 3.5 pounds of green olives.

Step-by-step explanation:

Given:

Susan is buying black and green olives from the Olive bar for her party. She buys 4 pounds of olives.

Black olives cost three dollars a pound. Green olives cost five dollars a pound.

She spends $15.50.

Now, to find the pounds of olives she buy.

Let the pounds of black olives be [tex]x.[/tex]

And the pounds of green olives be [tex]y.[/tex]

So, total pounds of olives:

[tex]x+y=4[/tex]

[tex]x=4-y[/tex]    ........( 1 )

As, given the cost of black olives $3 a pound.

And cost of green olives $4 a pound.

Now, the total money spends:

[tex]3x+4y=15.50[/tex]

Substituting the value of [tex]x[/tex] from equation (1) we get:

[tex]3(4-y)+4y=15.50[/tex]

[tex]12-3y+4y=15.50[/tex]

[tex]12+y=15.50[/tex]

Subtracting both sides by 12 we get:

[tex]y=3.5[/tex]

The green olives = 3.5 pounds.

Now, substituting the value of [tex]y[/tex] in equation (1):

[tex]x=4-y\\x=4-3.5\\x=0.5\ pounds.[/tex]

The black olives = 0.5 pounds.

Therefore, she buy 0.5 pounds of black olives and 3.5 pounds of green olives.

Final answer:

Susan bought 2.25 pounds of black olives and 1.75 pounds of green olives for her party, determined by solving a system of equations representing the total weight and cost of the olives.

Explanation:

How Many Pounds of Black and Green Olives did Susan Buy?

To determine how many pounds of black and green olives Susan bought, we need to create a system of equations based on the information provided:

Let x be the number of pounds of black olives Susan bought, and let y be the number of pounds of green olives.

The first equation will represent the total weight of olives:

1. x + y = 4 (since Susan bought 4 pounds of olives in total)

The second equation will represent the total cost of olives:

2. 3x + 5y = 15.50 (because black olives cost $3 per pound and green olives cost $5 per pound)

Now, let's solve this system of equations:

Multiplying the first equation by 3 gives us a new equation:
3x + 3y = 12

Now, we subtract this new equation from the second equation to find y:

(3x + 5y = 15.50) - (3x + 3y = 12)

2y = 3.50
y = 1.75

So, Susan bought 1.75 pounds of green olives. We can now substitute y into the first equation to find x:

x + 1.75 = 4
x = 4 - 1.75
x = 2.25

Therefore, Susan bought 2.25 pounds of black olives.

In conclusion, Susan bought 2.25 pounds of black olives and 1.75 pounds of green olives for her party.

Answer: 16 men

32 women

38 children

Step-by-step explanation:

Let x represent the number of men in the group.

Let y represent the number if women in the group.

Let z represent the number of children in the group.

A group of 86 people consist of men women and children. This means that

x + y + z = 86 - - - - - - - - - - - - 1

There are twice as many women than there are men. It means that

x = y/2

There are 6 more children than there are women. This means that

z = y + 6

Substituting x = y/2 and z = y + 6 into equation 1, it becomes

y/2 + y + y + 6 = 86

multiplying through by 2, it becomes

y + 2y + 2y + 12 = 172

5y = 172 - 12 = 160

y = 160/5 = 32

x = y/2 = 32/2

x = 16

z = y + 6 = 32 + 6

z = 38

There are 16 men, 32 women, and 38 children in the group.

Let the number of men be M, the number of women be W, and the number of children be C.

From the given information, we have the following equations:

W = 2M (Twice as many women as men)

C = W + 6 (6 more children than women)

The total number of people is given as 86:

M + W + C = 86

Substituting the values of W and C in terms of M into the third equation, we have:

M + 2M + (2M + 6) = 86

5M + 6 = 86

5M = 80

M = 16

Substituting the value of M in the first equation, we have:

W = 2(16) = 32

Finally, substituting the value of W in the second equation, we have:

C = 32 + 6 = 38

Therefore, there are 16 men, 32 women, and 38 children in the group.

Final answer:

The area of a square mural where the side length is a perfect square, represented as x², can be expressed as A = x⁴, which simplifies the concept of multiplying the side length by itself twice.

Explanation:

The area of a mural square, where the side length is a perfect square represented as x to the power of 2 (x²), is calculated by squaring the side length. Therefore, if x itself is a perfect square, the area A of the square mural is given by A = x² * x², which simplifies to A = x⁴. Since the side length is a perfect square, x could be expressed as y² where y is an integer, resulting in the area being y⁴, where y⁴ represents the side length squared twice.

To graph the sine function with provided features, we calculate the period from the frequency, acknowledge the midline at y = 2, and recognize the amplitude of 2. The first maximum is at (π, 4), giving us the complete function y = 2 sin(π/2 x) + 2.

To graph a sine function with the given features, we first recognize that the frequency of 1/4π means the period (T) of the function is the reciprocal of the frequency, or 4π. The amplitude of 2 indicates the function will oscillate 2 units above and below the midline, which is represented by y = 2. Since the function is not reflected over the x-axis and has a y-intercept of (0, 2), we start at the midline. The graph will reach its first maximum at (T/4, 2 + amplitude) which is (π, 4), since one quarter of the period will place us at a peak of the sine wave. The complete sine function derived from these features would be y = 2 sin(π/2 x) + 2.

Answer: the employee must make sales of $32000

Step-by-step explanation:

Let x represent the total sales that the employee makes in a month.

One employee of a computer store is paid a base salary of $2,000 a month plus an 8% commission on all sales over $7,000 during the month. This means that if the employee makes sales of $x in a month, his total earnings for that month would be

2000 + 8/100(x - 7000)

= 2000 + 0.08(x - 7000)

= 2000 + 0.08x - 560

= 0.08x + 1440

Therefore, for the employee to earn

a total of $4,000 for the month, the amount of sales would be

0.08x + 1440 = 4000

0.08x = 4000 - 1440

0.08x = 2560

x = 2560/0.08

Answer: the total distance that the object will fall after 6 seconds is 576 feet.

Step-by-step explanation:

The formula for determining the sum of n terms of an arithmetic sequence is expressed as

Sn = n/2[2a + (n - 1)d]

Where

n represents the number of terms in the arithmetic sequence.

d represents the common difference of the terms in the arithmetic sequence.

a represents the first term of the arithmetic sequence.

From the information given,

n = 6 seconds

a = 16 feet

d = 80 - 48 = 48 - 16 = 32

Therefore, the total distance the object will fall in 6 seconds is the sum of the first 6 terms, S6. It becomes

S6 = 6/2[2 × 16 + (6 - 1)32]

S6 = 3[32 + 32 × 5]

S6 = 3 × 192 = 576 feet

Final answer:

The total distance the penny falls in 6 seconds, according to the arithmetic sequence provided (16 feet the first second, 48 feet the second, and so on), is 576 feet.

Explanation:

The question involves calculating the total distance an object falls in a given number of seconds, according to an arithmetic sequence. In this case, the penny falls 16 feet in the first second, 48 feet in the second, and the distance increases by a constant amount each second. This is an arithmetic sequence where each term increases by 32 feet (48 - 16 = 32). To find the total distance, we sum the first six terms of the sequence.

The general formula for the nth term of an arithmetic sequence is a_n = a_1 + (n - 1) * d, where a_1 is the first term and d is the common difference. We can calculate the distance for each second and then add them up.

Here is how you calculate it:

First second: 16 feet

Second second: 16 + 32 = 48 feet

Third second: 48 + 32 = 80 feet

Fourth second: 80 + 32 = 112 feet

Fifth second: 112 + 32 = 144 feet

Sixth second: 144 + 32 = 176 feet

To find the total distance, add these values together:

Total distance = 16 + 48 + 80 + 112 + 144 + 176 = 576 feet.
