Consider the following regression output where the dependent variable is testscores and the two explanatory variables are the st

jeyben [28]

Answer:

The correct option is (A).

Step-by-step explanation:

The multiple linear regression equation is given by, $y=\alpha +\beta _{1} x_{1}+\beta _{2}x_{2}$ , where α = constant and β $_{i}$ = slope coefficients of regression line.

To test if there is a important relationship amid X $_{i}$ and Y, we use the t-statistic test.

The t-statistic for regression coefficient analysis is given by,

$t=\frac{\beta_{i}}{S.E._{\beta_{i}}}$

The regression equation for test scores dependent upon the two explanatory variables, the student-teacher ratio and the percent of English learners is:

$\text{TestScore} = 698.9 - 1.10 \text{ STR} - 0.650 \text{ PctEL}$

A t-test for the significance of the regression coefficient of variable student-teacher ratio (STR) is conducted.

The test statistic is found to be, t = 2.56.

The regression coefficient of variable STR is, 1.10.

Compute the standard error of the regression coefficient as follows:

$t=\frac{\beta_{i}}{S.E._{\beta_{i}}}$

$S.E._{\beta_{i}}=\frac{\beta_{i}}{t}$

$=\frac{1.10}{2.56}\\\\=0.4296875\\\\\approx 0.43$

The standard error of the regression coefficient is 0.43.

Thus, the correct option is (A).

What transformations are applied to the graph of the function f(x)=10^x to produce the function g(x)=3(10)^x-2

tatiyna

Answer:

D) A vertical dilation by a factor of 3 and a vertical shift down 2 units

Step-by-step explanation:

Given

f(x)=10^x
g(x)=3(10)^x - 2

We see that:

g(x) = 3f(x) - 2

This is a vertical stretch by a factor of 3 and translation down 2 units

Correct choice is D

Perform the indicated operation and simplify the result.

hodyreva [135]

Answer:

The answer is

$\frac{(2x - y)(2x + y)}{(4x + 3y)(2x + y)} \times \frac{(4x + 3y)(x - 3y)}{(2x + y)(x - 3y)} \\ \\ = \frac{2x - y}{4x + 3y} \times \frac{4 + 3y}{2x + y} \\ \\ = \frac{2x - y}{2x + y}$

Hope this helps you

Billy received a raise after his first year on the job to $45,000 from his initial salary of $42,400. What was his real raise st

solong [7]

Billy get 5.9% raise after completing first year.

<h3>What is PERCENTAGE?</h3>

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100.

Here, Billy's initial salary = $ 42,500

After raise, salary become $ 45,000

Change in salary = Raised salary - Initial salary

= 45000 - 42500

= $ 2500

% Change = change / initial salary X 100

= 2500 / 42500 X 100

= 0.0589 X 100

≈ 5.9 %

Thus, Billy get 5.9% raise after completing first year.
