Answer:
44 swimmers
Step-by-step explanation:
Given the data points :
66, 8) (71, 23) (72 16) (75 30) (78 35) (80 24) (82 37) (86 37) (87 42) (90 50)
Temperature X:
66
71
72
75
78
80
82
86
87
90
Number of swimmers Y:
8
23
16
30
35
24
37
37
42
50
Using the online regression calculator :
The regression model obtained is ;
ŷ = 1.5045X - 88.2056
Where
1.5045 = gradient or slope
-88.2056 = intercept
x = independent variable
y = dependent variable
Number of swimmers when temperature = 88
y = 1.5045(88) - 88.2056
y = 44.19
y = 44 (nearest whole number)
Answer:

I am not shure that is right but I think an ordered pair is form of a funtion.
Answer:
x = 169º
Step-by-step explanation:
So we know that a straight line equals 180º. Now we have to come up with an equation. We're given 11º so the equation should look like:
x + 11 = 180 or 180 - 11 = x
I'll solve for both.
x + 11 = 180
-11 -11
x = 169
180 - 11 = x
180 - 11 = 169
x = 169
