She starts off with $10.25 and gets a raise of $0.50, so she earns $10.75 per hour. Then she gets a raise of 10%, so then 10.75 x 0.10 = 1.075, so she earns $11.825 per hour. Then her third raise is $0.50 so she earns $12.325 per hour. The raise for next summer is 5%, so 12.325 x 0.05 = 0.61625, so she earns $12.94125. She will earn about $12.94 per hour starting off next summer.
<h3>Use the formula y2- y1 over x2-x1 so it should look like this 1-3 over 3-1 which is -2 over 2 then you divide that which is -1 and if you have to find one all you have to do is use one point label which is x and y so I pick (1,3) so you put 3=-1(1) once you have that you multipy so -1 times 1 is -1 so your gonna add 1 to the -1 and the three the -1 cancel out because it is a zero pair 3+1 is 4 so B=4 </h3>
As with simple linear regression, we desire the residuals to:
Have constant variance.
Have a mean close to 0.
<h3>What is a simple linear regression?</h3>
It should be noted that a simple linearregression simply means a model that describes the relationship between a dependent variable and an independent variable.
In this case, as with simple linearregression, we desire the residuals to have constant variance and have a mean close to 0.
