Answer:

$83.60

Step-by-step explanation:

to find the answer you need to know the price of one pint (unit rate) so we divide 12.54 by 6.

12.54 ÷ 6 = 2.09

then we multiply that by 40

2.09 x 40 = 83.60

A road is inclined at an angle of 6°. After driving 5,440 feet

Natalija [7]

<h3>Answer: B) 569 feet</h3>

========================================================

Work Shown:

sin(angle) = opposite/hypotenuse

sin(6) = a/5440

5440*sin(6) = a

a = 5440*sin(6)

a = 568.634840176034

a = 569 feet, which shows why <u>choice B</u> is the answer.

This value is approximate. Make sure your calculator is in degree mode. One way to check is to compute sin(30) and you should get 0.5

side note: 569 feet is roughly equal to 0.1078 miles.

The admissions officer for Clearwater College developed the following estimated regression equation relating the final college G

emmainna [20.7K]

A null hypothesis illustrates that two variables in the hypothesis have no statistical significance.

The null hypothesis is: $\mathbf{H_0 : \beta = 0}$

The regression equation is given as:

$\mathbf{\bar y = -1.41 + 0.02351x_1 + 0.0048x_2}$

The variables are: $\mathbf{x_1}$ and $\mathbf{x_2}$

The null hypothesis states that, there is no statistical significance between $\mathbf{x_1}$ and $\mathbf{x_2}$ .

This is represented as:

$\mathbf{H_0 : \beta = 0}$

Hence, the null hypothesis is: $\mathbf{H_0 : \beta = 0}$
