Answer:

Step-by-step explanation:

In a multiple regression model X1 and X2 are two independent variables and the assumption is made that the effect of of X1 and X2 on dependent variables is independent of each other.For example let y be the student grade and x1 is the study hour and x2 be the IQ level of student so the multiple regression model for this scenario will be

Y=b0+b1x1+b2x2+e

Hence we can see that effect of study hour and IQ level on the student grade and the effect of study hour on the student grade is independent of the value of IQ level.

Sandeep uses 1/5 of a cup of vinegar in his salad dressing recipe. How much vinegar would Sandeep use to make 4/5 of a recipe?

Westkost [7]

Answer:

4 /25

Step-by-step explanation:

Given that :

Cup of vinegar used per recipe = 1/5 cup

Amount of vinegar to be used for 4/5 of a recipe ;

1 cup recipe = 1/5 cup vinegar

4/5 cup recipe = x

Cross multiply :

x = 1/5 * 4/5

x = 4/25 cup

Hence, Sandeep will use 4/25 cup of vinegar

Consider the graph of function f. Find the average rate of change for f on the interval [P,Q]

Ulleksa [173]

Check the picture below.

$\bf slope = m = \cfrac{rise}{run} \implies \cfrac{ f(x_2) - f(x_1)}{ x_2 - x_1}\impliedby \begin{array}{llll} average~rate\\ of~change \end{array}\\\\[-0.35em] \rule{31em}{0.25pt}\\\\ f(x)= \qquad \begin{cases} x_1=1\\ x_2=3 \end{cases}\implies \cfrac{f(3)-f(1)}{3-1}\implies \cfrac{(5)-(-1)}{3-1} \\\\\\ \cfrac{5+1}{2}\implies \cfrac{6}{2}\implies 3$

(2x + 7y = -24<br>18x+y=12 solve by substitution

const2013 [10]

Answer:

x = .87, or when approximated to a fraction, 27/31

y = -3.67, or when approximated to a fraction, -1287/350

Step-by-step explanation:

Lets start by rewriting out our equations

2x + 7y = -24

18x + y = 12

Lets solve for a y value; the second equation is easiest, as the y value has no coefficient (the number that is multiplied times a variable). To do this, lets move the 18x to the other side. Now our two equations look like:

2x + 7y = -24

y = -18x + 12

Next, lets plus the second equation into the first equation in regards to y.

2x + 7(-18x + 12) = -24

Now, lets solve!

2x -126x + 84 = -24

Then, combine your terms!

-124x = -108

Divide by (-124)!

x = -108/-124

x = 27/31

Now that we know x, lets plug this back in to the first equation to find y!

2(27/31) + 7y = -24

1.74 + 7y = -24

7y = -25.74

y = -3.67, or when approximated to a fraction, -1287/350
