Answer:

B. The slope of Function A is less than the slope of Function B.

Step-by-step explanation:

Function A slope: 4/1x or 4x

equation: y = 4x + 2

Function B slope: 5x

equation: y = 5x + 5

5 is bigger than 4.

Semenov [28]

Complete Question

Pennsylvania Refining Company is studying the relationship between the pump price of gasoline and the number of gallons sold. For a sample of 14 stations last Tuesday, the correlation was 0.65.At the 0.01 significance level Can the company conclude that the correlation is positive

Answer:

Yes the company conclude that the correlation is positive

Step-by-step explanation:

From the question we are told that

The sample size is n = 14

The correlation is r = 0.65

The null hypothesis is $H_o : r < 0$

The alternative hypothesis is $H_1 : r > 0$

Generally the standard deviation is mathematically evaluated as

$Sr = \sqrt{1- r}$

$Sr = \sqrt{1- 0.65}$

$Sr = 0.616$

The degree of freedom for the one-tail test is

$df = n- 2$

$df = 14- 2$

$df = 12$

The standard error is evaluated as

$SE = \frac{0.616}{ \sqrt{12} }$

$SE =0.1779$

The test statistics is evaluated as

$t = \frac{r }{SE}$

$t = \frac{0.65 }{0.1779}$

$t = 3.654$

The p-value of of t is obtained from the z table, the value is

$p-value = P(t < 3.654) = 0.00012909$

Given that $p-value < \alpha$ then we reject the null hypothesis

Hence the company can conclude that the correlation is positive

A graph Includes the ordered pair (2,4). Write two different rules that would be possible for this graph. Explain how you found

Vanyuwa [196]

We know that
An ordered pair is used to locate a point on a coordinate grid.
The first number in an ordered pair is the x-coordinate, and the second number in an ordered pair is the y-coordinate.

In this problem, the ordered pair is
$(2,4)$
so
the x-coordinate is equal to $2$
the y-coordinate is equal to $4$

therefore

Rule N 1
The y-value is $2$ times the x-value

Rule N 2
The y-value is $2$ greater than the x-value

Both are possible because their solutions include the ordered pair listed

The top has a diameter of 25cm and the bottom has a radius of 10cm what is the total length of edging will it be

ruslelena [56]

I'll take a stab here

Originally I thought this was something complicated, like surface area or volume, in which the answer would have been hard to determine given the fact that trash bins are different widths at the top and bottom.

However, with the info you just gave me, I believe this is more of a simple circumference problem.

So, in math, you have a triangle of equations relating to pi. R*2=Diamater, Diameter*3.14=circumference, circumference/3.14=Diameter, etc.

So, here you are given the diameter of the top and radius of the bottom of the bin. The top is 25 cm (d), the bottom is 10 cm (r). ACROSS, First, you want to make both measurements the same.

So, leave 25cm (d) alone, but change the 10 cm (r) to diameter (d). So, radius *2= diameter, so 10*2=20, so the top is 25 cm (d) and the bottom is 20 cm (d).

Next you need to find the circumference (around the edge length, imagine the wrapper on a water bottle, that wrapper goes completely around the bottle and comes back to touch its end. That's circumference.)

So, circumference is diameter * pi (3.14, calculated originally by Archimedes, but pi is actually infinite digits)

So, 25*3.14 (use a calculator as expected) =78.5
And 20*3.14 =62.8

Add the two together to find out how much length of whatever she wants to put on the bin she needs.

78.5+62.8=141.3

You can round and say she needs 142 cm of decoration.

This is assuming that she wants to put 2 decorations on the bin, one on the top, one on the bottom, going around the bin, as that is what I understood from the question.

~Hope this helps!
