Answer:
liam
Step-by-step explanation:
We have, 25% × x = 150
or,
25
100
× x = 150
Multiplying both sides by 100 and dividing both sides by 25,
we have x = 150 ×
100
25
x = 600
If you are using a calculator, simply enter 150×100÷25, which will give you the answer.
Step-by-step explanation:
Regression analysis is used to infer about the relationship between two or more variables.
The line of best fit is a straight line representing the regression equation on a scatter plot. The may pass through either some point or all points or none of the points.
<u>Method 1:</u>
Using regression analysis the line of best fit is: 
Here <em>α </em>= intercept, <em>β</em> = slope and <em>e</em> = error.
The formula to compute the intercept is:

Here<em> </em>
and
are mean of the <em>y</em> and <em>x</em> values respectively.

The formula to compute the slope is:

And the formula to compute the error is:

<u>Method 2:</u>
The regression line can be determined using the descriptive statistics mean, standard deviation and correlation.
The equation of the line of best fit is:

Here <em>r</em> = correlation coefficient = 
and
are standard deviation of <em>x</em> and <em>y</em> respectively.

12
Note:
Since there is no y value m can not be determine. Therefore finding the sum here can not be determined so instead you can try simplifying
