Answer:
1. 45 minutes a day cycling
2.$1.55 on each cup of coffee a day
Step-by-step explanation:
1. You would figure up how much he jogs per week by multiplying 15 times 5 which would be 75 minutes and then from there you would subtract 75 from 300 and get 225 and divide 225 and 5 and end up with 45
2. You would multiply $.75 by 4 to figure up how much he spends on donuts which is $3 and then subtract 15.40 from 3 and get 12.40 and divide 12.40 by 8 since he goes twice a day and end up with 1.55
The answers would be 320ft. Squared
Answer: 0.22
Step-by-step explanation:
We know that the best point estimate for the difference between two population mean is the difference between their sample means.
Given : For the 39 randomly selected upperclassmen, the sample mean was 0.12 and sample standard deviation was 0.42. For the 35 randomly selected underclassmen, the sample mean was 0.34 and the sample standard deviation was 0.87.
Let A denotes the population of upperclassmen and B denotes the population of underclassmen .
Then, the point estimate of the difference in the population mean volunteered between underclassmen and upperclassmen will be :-
Hence, the point estimate of the difference in the population mean volunteered between underclassmen and upperclassmen =0.22
Answer:
( x - (-1) )^2 + ( y - (-1) )^2 = 3^2
Step-by-step explanation:
The equation of a circle is ( x - h )^2 + ( y - k )^2 = r^2, r is the radius.
(h,k) is the coordinates for the center point.
In this image, it appears K is 3 units away from any point on the circle, making 3 the radius.
Our equation is now ( x - h )^2 + ( y - k )^2 = 3^2
Now, we need to find the coordinate of K; the center point.
K's x is -1 and K's y is also -1.
Our equation is now:
( x - (-1) )^2 + ( y - (-1) )^2 = 3^2
