Answer: -0.95
Step-by-step explanation:
The value that explains the least-squares regression line is 90% or 0.9, and is also r^2.
You would just square root r^2 and get r=0.948. since the relationship is negative, r= -0.948, or -0.95
Answer:
4.75
Step-by-step explanation:
For 2 weeks.
In a week there are 7 days.
So for 2 weeks there are a total of 2*7 = 14 days.
So there would be 14 mornings
And if each morning he runs 50 minutes,
So for the 14 mornings = 14 * 50 = 700 minutes
700 minutes converting to hours = 700 / 60 = 11 hours remainder of 40 minutes
So total time = 11 hours and 40 minutes
Hope this explains it.
Answer:
7m
Step-by-step explanation:
v=πr^2h
769.3=3.14*r^2*5
769.3=15.7r^2
769.3/15.7=15.7r^2/15.7
49=r^2
√49=√r^2
√49=r
r=7m
