Why might the graph be considered misleading?
The scales on the x- and y-axes are unequal.
The interval on the x-axis is too large for the data set.
The scale on the y-axis misrepresents the difference in the heights of the bars.
The interval on the y-axis is too large for the data set.

The slope of the line through the points (-1,6) and (7,-2) is -1. Substitute this and one of the points into the point-slope form, 'y - y1 = m (x - x1)', to get the equation of the line. The final equation is y = -x + 5.

To complete the equation of the line through points (-1,6) and (7,-2), we first need to find the slope (m) of the line using the formula m=(y2-y1)/(x2-x1). Here, (-1,6) is (x1,y1) and (7,-2) is (x2,y2). When we substitute these values in, we get m=(-2-6)/(7-(-1)), which simplifies to m=-8/8 or m=-1.

Now, you can use the point-slope form of a line, which is y - y1 = m (x - x1). You can use either of the points given, but let's use (-1,6). The equation then becomes y - 6 = -1(x - (-1)). To simplify, this becomes y - 6 = -x - 1. If you add 6 to both sides, the final equation of the line is y = -x + 5.

Answer:

3a5b

Step-by-step explanation:

Answer:

yes; 5

Step-by-step explanation:

To determine if the sequence is arithmetic, take the second term and subtract the first term

-7 - (-12) = -7+12 = 5

This would be the common difference if our sequence is arithmetic

Now take the second term and add the"common difference"

-7+5 = -2  This is our third term

-2+5 = 3  This is our fourth term

The sequence is arithmetic with a common difference of 5

Step-by-step explanation:

Answer:

B. greater mean = class B greater median = class B

Step-by-step explanation:

The 21 compartments will be fully filled and the last compartment will contain 3 towels.

The number of compartments that will be filled =  total number of towels/ capacity of one compartment.

So we have 150 towels / 7 towels per compartment ≈ 21.43.

Since we can't have a fraction of a compartment, this means that 21 compartments will be fully filled.

The remaining towels can be found = the total number of towels - the number of towels that fit into the full compartments

Total no. of towels that fit into all compartments = 21 compartments × 7 towels each = 147 towels.

Therefore, we have 150 - 147 = 3 towels left, which will be in the compartment that is not completely filled.

There are 21 compartments filled with towels, and in the 22nd compartment, there will be 3 towels.

Number of compartments filled: 21 compartments  

Towels in a partially filled compartment: 6 towels  

To calculate the number of compartments filled, we need to divide the total number of towels by the maximum number of towels each compartment can hold:

[tex]\( \text{Number of compartments filled} = \frac{\text{Total number of towels}}{\text{Maximum towels per compartment}} \)[/tex]

[tex]\( \text{Number of compartments filled} = \frac{150}{7} = 21.4285 \)[/tex]

Since we can't have a fraction of a compartment, we round down to the nearest whole number, which is 21.

To find out how many towels will be in a compartment that is not completely filled, we subtract the total number of towels already placed in filled compartments from the total number of towels:

[tex]\( \text{Remaining towels} = \text{Total number of towels} - (\text{Number of compartments filled} \times \text{Maximum towels per compartment}) \)[/tex]

[tex]\( \text{Remaining towels} = 150 - (21 \times 7) = 150 - 147 = 3 \)[/tex]

So, there are 21 compartments filled with towels, and in the 22nd compartment, there will be 3 towels.

So:

We rewrite [tex]8x^{24}\ as\ (2x ^ 8) ^ 3[/tex]

We rewrite[tex]27y ^ 6\ as\ (3y ^ 2) ^ 3[/tex]

(2x ^ 8) ^ 3- (3y ^ 2) ^ 3

Since both terms are perfect cubes, factor using the cube difference formula:

[tex]a ^ 3-b ^ 3 = (a-b) (a ^ 2 + ab + b ^ 2)[/tex]

Where:

[tex]a = 2x ^ 8\\b = 3y ^ 2[/tex]

Rewriting:

[tex](2x ^ 8-3y ^ 2) ((2x ^ 8) ^ 2 + (2x ^ 8) (3y ^ 2) + (3y ^ 2) ^ 2) =\\(2x ^ 8-3y ^ 2) (4x ^{16} + 6x ^ 8y ^ 2 + 9y ^ 4)[/tex]

To find: the value of x.

Solution: It is given that circle O is circumscribed about quadrilateral ABCD such that ∠ABC=91° and ∠ADC=x-15°.

We know that the sum of opposite angles of the cyclic quadrilateral is 180°, therefore

[tex]{\angle}ABC+{\angle}ADC=180^{\circ}[/tex]

Substituting the given values, we have

[tex]91^{\circ}+x-15^{\circ}=180^{\circ}[/tex]

[tex]x+76^{\circ}=180^{\circ}[/tex]

[tex]x=104^{\circ}[/tex]

thus, the value of x is [tex]104^{\circ}[/tex].

Answer:

x =16

Step-by-step explanation:

You can use Theorem Pythagoras method to solve this question.

The formula is a^2 + b^2 =c^2

In this question a=x , b=12, and c= 20

to find a which means x you should use this formula : c^2 - b^2=20^2-12^2

= 400 - 144

=√256

=16

You also can use another method by using the second diagram.

In that diagram you have to know that 12÷3 is 4, 20÷5 is 4, hence x÷4 is 4

so , x=16.

I hope this two ways for answering this question will be helpful for you.

Answer:

100%-25%=75%=75/100=0.75

substitute

[tex]\frac{x}{y}*\frac{0.50}{0.75} =\frac{2}{3}(\frac{x}{y})[/tex]

therefore

The percent that the fraction will decrease is equal to

[tex](1-\frac{2}{3})*100=33.33\%[/tex]

y = ln( x + 6 ) - 11

h = 6

k = -11

h + k = -5

Step-by-step explanation:

Horizontal shift changes whats inside the brackets, in other words, changes just the x-value.If the shift is right, the number should be subtracted, if the shift is left, the number should be added.

Vertical shift changes the equation as a whole.if the shift is up, the number of should be added.If the shift is down, the number should be subtracted.

The changes given to us are 3 units left ( horizontal translation ) and 5 units down ( vertical translation )

If we rewrite the equation, we have:

y = ln( x + 3 + 3 ) - 6 - 5

y = ln( x + 6 ) - 11

Answer:

The size of Harry's loan is $9000.

Step-by-step explanation:

D(t) models Harry's remaining debt, in dollars, as a function of time t, in months  that is given by :

[tex]D(t) =-200t+ 9000[/tex]

We can see 200 is in negative that means it is getting deducted from the function. So, Harry must be paying this each month against his loan.

Lets put t = 0, that shows no payments have been made.

This will get the amount of loan, before any payments.

[tex]D(t)=-200(0)+9000[/tex]

So,[tex]D(t) =9000[/tex]

Hence, the size of Harry's loan is $9000.

Answer:

13

Step-by-step explanation:

You need to use the Pythagorean theorem. Which is a^2+b^2=c^2

so 5^2+12^2

which simplifies to 25+144=c^2

then it simplifies to 169=c^2

Now you take the square root

c=sqrt(169)

c=13

For this case we have that by definition, the Pythagorean theorem states that:

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

Where:

c: It is the hypotenuse

a, b: Are the legs

Substituting the values of the figure:

[tex]c = \sqrt {5 ^ 2 + 12 ^ 2}\\c = \sqrt {25 + 144}\\c = \sqrt {169}\\c = 13[/tex]

Thus, the value of the hypotenuse is 13.

Answer:

13

Option B

I am pretty sure it’s step one

Answer:

B

Step-by-step explanation:

Given the 2 equations

x³ + y = 0 → (1)

11x² - y = 0 → (2)

Add (1) and (2) term by term to eliminate the term in y

x³ + 11x² = 0 ← factor out x² from each term

x²(x + 11) = 0

Equate each factor to zero and solve for x

x² = 0 ⇒ x = 0

x + 11 = 0 ⇒ x = - 11

Substitute these values into (1) for corresponding values of y

(1) y = - x³

x = 0 ⇒ y = 0 ⇒ (0, 0) is a solution

x = - 11 ⇒ y = - (- 11)³ = 1331 ⇒ (- 11, 1331) is a solution

The faster computer will take approximately 22.5 minutes to do the job on its own.

Let's assume that the faster computer can complete the job on its own in x minutes.

If the slower computer takes 45 minutes to complete the job on its own, it means that in 1 minute it completes 1/45th of the job.

Working together, the two computers can complete the entire job in 15 minutes. So in 1 minute, they can complete 1/15th of the job.

Therefore, 1/45 + 1/x = 1/15

Simplifying the equation, we get 1/x = 1/15 - 1/45

Substituting the numerator values with a common denominator, 1/x = (3/45) - (1/45) = 2/45

Now, solving for x, we get x = 45/2 = 22.5

So, it will take the faster computer approximately 22.5 minutes to do the job on its own.

The probability that an item is either Large or Blue, [tex]\( P(\text{Large or Blue}) \)[/tex], is 0.7 after simplification.

To find the probability [tex]\( P(\text{Large or Blue}) \)[/tex], we will use the principle of inclusion-exclusion. The formula for two events A and B is:

[tex]\[ P(A \text{ or } B) = P(A) + P(B) - P(A \text{ and } B) \][/tex]

Let's define our events as:

- A = The event that an item is Large.

- B = The event that an item is Blue.

Looking at the table:

- The probability that an item is Large, [tex]\( P(\text{Large}) \)[/tex], is the sum of all Large items divided by the total number of items.

- The probability that an item is Blue, [tex]\( P(\text{Blue}) \)[/tex], is the sum of all Blue items divided by the total number of items.

- The probability that an item is both Large and Blue, [tex]\( P(\text{Large and Blue}) \)[/tex], is the number of items that are both Large and Blue divided by the total number of items.

From the table:

Now we can calculate the probabilities:

[tex]\[ P(\text{Large}) = \frac{25}{40} \][/tex]

[tex]\[ P(\text{Blue}) = \frac{20}{40} \][/tex]

[tex]\[ P(\text{Large and Blue}) = \frac{17}{40} \][/tex]

Using the inclusion-exclusion principle:

[tex]\[ P(\text{Large or Blue}) = P(\text{Large}) + P(\text{Blue}) - P(\text{Large and Blue}) \][/tex]

Let's do the calculations.

The probability of an item being Large or Blue is [tex]\( P(\text{Large or Blue}) = 0.7 \)[/tex], which is already in its simplest form.

Percent error = |(Measured - Actual) / Actual| × 100. For Measured 68, Actual 60: [tex]\( \frac{|68 - 60|}{60} \times 100 ≈ 13.3\% \).[/tex]

To find the percent error, you can use the formula:

[tex]\[ \text{Percent Error} = \left| \frac{\text{Measured Value} - \text{Actual Value}}{\text{Actual Value}} \right| \times 100 \]\\[/tex]

Given:

- Measured Value = 68

- Actual Value = 60

Substitute these values into the formula:

[tex]\[ \text{Percent Error} = \left| \frac{68 - 60}{60} \right| \times 100 \]\[ \text{Percent Error} = \left| \frac{8}{60} \right| \times 100 \]\[ \text{Percent Error} = \left| 0.1333... \right| \times 100 \]Now, rounding to the nearest tenth:\[ \text{Percent Error} ≈ 13.3\% \]\\[/tex]

So, the percent error is about 13.3%. This indicates that the measured value is approximately 13.3% higher than the actual value.

The percent error, rounded to the nearest tenth, is about 13.3%.

To find the percent error, you can use the following formula:

[tex]\[\text{Percent Error} = \frac{{|\text{Estimated Value} - \text{Actual Value}|}}{{\text{Actual Value}}} \times 100.\][/tex]

Here, the estimated value is 68 marbles, and the actual value is 60 marbles.

Calculate the absolute error :

  [tex]\[ |\text{68 - 60}| = 8. \][/tex]

Calculate the relative error :

[tex]\[ \frac{{8}}{{60}}. \][/tex]

Convert to percentage :

[tex]\[ \frac{{8}}{{60}} \times 100 = 13.333. \][/tex]

Round to the nearest tenth :

[tex]\[ \approx 13.3.[/tex]

Thus, the percent error, rounded to the nearest tenth, is about 13.3%.
