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

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
