Answer:
170 muffins
Step-by-step explanation:
We start from the ratio between baker B and C
The ratio of cakes baked by both is 4:3.
We know baker C baker 150 muffins:
This mathematically means:
B:C = 4:3 = B:150
This means 4/3 = B/150
B = (4 * 150)/3 = 200
Baker B baked 200 cakes
We now move back to the first statement
The ratio between baker A and B is 8:5
Mathematically, this means:
A:B = 8:5 = A:200
8/5 = A/200
A = (8 * 200)/5 = 320
The number of cakes baker A baker pass baker C would be 320 - 150 = 170 muffins
The absolute value is the distance from 0, so it would be 4 and -4
The correct answer is: <span>D. The regression line is not a good model because the points in the residual plot form a curve. (i know this because i just passed the test ;) )</span>
