Each of the options below describes a relationship that you need to graph on a coordinate plane. Which of the options will have a slope of 8? Select all that apply. A) Doing 4 pages of homework in 20 minutes B) Cycling 32 miles in 4 hours C) Buying 10 shirts for $80 D) Reading 72 pages in 9 hours

Answers

Answer 1

Answer:

B ; C; D

Step-by-step explanation:

The slope measures the rate of change in the dependent variable per unit change in the independent variable :

From the options :

Doing 4 pages of homework in 20 minutes :

The number of pages done per minute = slope

Slope = 20 / 4 = 5

To cycle 32 miles in 4 hours:.

Number of miles to cycle per hour to achieve the feat :

Slope = 32 /4 = 8

Buying 10 shirts for $80:

Cost per shirt = slope

Slope = $80 / 10

Slope = 8

Reading 72 pages in 9 hours

Number of pages read per hour :

72 / 9 = 8 pages

For the data in the table, tell whether y varies directly with x. If it does, write an equation for the direct variation.


A.
yes; x = 1.8y


B.
no


C.
yes; y = 1.8x

Answers

Answer:

C.

yes; y = 1.8x

Step-by-step explanation:

Answer for the question :

Yes, Y varies directly with X, and the equation is :

Y = 1.8X

NOTE : For every value of X, when you multiply them with 1.8, you will get the corresponding Y.  

Y = 1.8 x X

5.4 = 1.8 x 3

12.6 = 1.8 x 7

21.6 = 1.8 x 12   (Q.E.D.)

That’s the answer, good luck in solving the question!

:-)

ideal all you ought to do is to divide the y via potential of x and u get the equation working occasion #a million y=32 / x=4 then u have y/x=32/4 ----> y=8x and do the comparable indoors something so #2 y=-20 & x=-20 so y/x=-20/-20 y=x etc

The linear equation is given as y = 1.8x, Then the correct option is C.

What is the equation of a line passing through two points?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂). Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

The table is given below.

x         y

3      5.4

7      12.6

12     21.6

Then the linear equation is given as,

[tex]\rm (y - 5.4) = \left [\dfrac{5.4-12.6}{7-3} \right] (x-3)[/tex]

Simplify the equation, then we have

y - 5.4 = 1.8(x - 3)

y - 5.4 = 1.8x - 5.4

y = 1.8x

The linear equation is given as y = 1.8x, Then the correct option is C.

Find the 75th term of the following arithmetic sequence.
6, 11, 16, 21,

Answers

Answer:

The 75th term in the sequence is 16

Step-by-step explanation:

The 75th term of a sequence can be considered as the term that is in the position at 75% along the sequence. This is assuming that the sequence has been sorted already from lowest value to highest value

In this sequence, which has 4 terms, we can find the 75th term by finding what term is at 75% (or three-quarters) along the sequence.

To find the 75th term:

Multiply the number of terms by 0.75 (or 75%/100%) :

             0.75*4 terms= 3

Then, we find the value of the term that is at position 3 from the left (lowest number)

In this case, the term that is at the 3rd position from the left is 16

Thus, the 75th term in the sequence is 16

Step-by-step explanation:

Ok there are some working areas here that I am working out but I do know that if you break down the total amount paid out to the scientists and engineers, there would be 7 scientists and 4 engineers

$1038 so if you take $66 multiplied by 7 you get $462. Multiply $144 by the remaining 4 and you get $576. The total will equal $1038. This should all help you put together the right equation because the answers are correct.

A) 8.1 m^2

B) 4.0 m^2

C) 46.0 m^2

D) 11.7 m^2

Answers

Answer:

[tex]A=11.7\ m^2[/tex]

Step-by-step explanation:

Given that,

Central angle, [tex]\theta=160^{\circ}[/tex]

Diameter,d = 5.8 m

Radius, r = 2.9 m

We need to find the area of sector. The formula for the area of sector is given by :

[tex]A=\dfrac{\theta}{360}\times \pi r^2\\\\=\dfrac{160}{360}\times 3.14\times 2.9^2\\\\=11.7\ m^2[/tex]

So, the area of a sector is equal to [tex]11.7\ m^2[/tex].

Answer:

Step-by-step explanation:

a triangles Angel's should add up to 180 all together

So, 71+64=135

180-135= 45

now that you have found the missing angle, you need to find x.

set the equation equal to 45:

8x-11=45

now solve:

8x-11 =45

add 11 to both sides to cancel out the negative 11 and try to get x alone:

8x=56

divide 8x by 8 and 56 by 8 to get x alone:

x=7

Suppose that the delivery times of a nationwide pizza chain are normally distributed with an unknown mean and standard deviation. The delivery times of 26 randomly sampled pizza orders are used to estimate the mean delivery time for the population. What t-score should be used to find the 95% confidence interval for the population mean?

Answers

Answer:

The t-score to be used to find the 95% confidence interval for the population mean is;

[tex]t_{(0.025, \, 25)} = 2.06[/tex]

Step-by-step explanation:

The t-score which is representative of a point with n - k (n, and k represents the sample size and the number of groups in the test respectively) degrees of freedom  from the Student's T-distribution is a standard test statistic obtained by applying a T-test

Therefore, the t-score used for a confidence interval is obtained by by making use of the the following information;

The number of degrees of freedom = n - k

The confidence level in the confidence interval

The parameters given in the question are;

The number of pizza orders in the sample, n = The sample size = 26

The number of samples used in the estimate, k = 1 group of 26 randomly sampled pizza

The level of confidence (the probability) that the interval contains the population mean = 95%

Therefore, the significance level, α = 1 - 95% = 1 - 95/100 = 0.05

∴ The α-level for the upper and lower limit of the interval are α/2 = 0.05/2 = 0.025 long

The degrees of freedom, df = n - k

∴ For the estimation, DF = 26 - 1 = 25

The t-statistic is therefore the t-value at the intersection of the row for DF = 25 and the 0.025 (one-tail) column (0.025 two-tail column) which gives;

[tex]t_{(\alpha /2, \, DF)} = t_{(0.025, \, 25)} = 2.06[/tex]
