A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a pers

tino4ka555 [31]

Answer:

19 situps

Step-by-step explanation:

Given that the regression equation to find a a relationship between hours of TV watched per day (x) and number of situps a person can do (y) was done.

The result was

y = ax+b

$y = -1.23x+22.738\\$

Correlation coefficient = 0.865

To predict the number of situps a person who watches 3 hours of TV

y = -1.23(3)+22.738

= 19.048

Approximately 19 situps.

A motorboat takes 3 hours to travel 108 kilometers going upstream. The return trip takes 2 hours going

IRISSAK [1]

Answer:

45 km/h and 9 km/h

Step-by-step explanation:

Let the rate of boat in still water be b and the speed of the current be c

Speed downstream = b + c
Speed upstream = b - c

We got equations for time:

108/(b - c) = 3 ⇒ b - c = 36
108/(b + c) = 2 ⇒ b + c = 54

Add up the equations:

b - c + b + c = 36 + 54
2b = 90
b = 45 km/h

Then finding the values of c

c = 45 - 36 = 9 km/h
