Me ! an equation was used to predict possible weights of puppies at 6 months of age. the actual weights of the puppies are also listed. actual weight (ounces) 9 15 16 20 20 26 predicted weight (ounces) 9 12 15 18 21 24 the sum of the residuals is

7

Step-by-step explanation:

Given :

Actual weight (ounces)             Predicted weight (ounces)21

9                                                        9

15                                                        12

16                                                         15

20                                                        18

20                                                        21

26                                                        24

To Find : the sum of residuals

Solution :

Actual - Predicted=Residuals

9-9=0

15-12=3

16-15=1

20-18=2

20-21=-1

26-24=2

So, the residuals are 0,3,1,2, -1,2

Thus the sum of all residuals = 0+3+1+2-1+2 = 7

Hence the sum of residuals is 7

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
