P is equal to plus or minus 2 because it'll both be equal to 4
3y=7. x-5+5=3y-5 x-3y=-5 -3y+3y x-3y=-5
In order to solve for x, you need to get it by itself. To get it by itself you need to get rid a A by subtracting it from both sides.
Answer:
a. Use the regression equation
Step-by-step explanation:
Given

What can be used to predict diameter, given family income
We can see (by observation) that the data on the table can only be represented on a scattered plot, and scattered plot uses regression equation for data prediction.
i.e.
--- equation of line of best fit
In this case;


<em>When the x value (income) is known, we can simply plug in the value in the above equation to get the y value (diameter)</em>
A = LW....L = A/W
A = 93.5
W = 8.5
L = 93.5 / 8.5
L = 11....the length of the cake is 11 inches
