The number of soccer players is 4 times the number of volleyball players
Answer:
2.75
Step-by-step explanation:
Divide 13.75 by five.
Step-by-step explanation:
Margin of error = critical value × standard error
ME = CV × SE
At 95% confidence and 20 degrees of freedom, CV = 2.086.
SE = s / √n
SE = 0.16 / √21
SE = 0.035
So the margin of error is:
ME = 2.086 × 0.035
ME = 0.073
Answer:
12.71in
step explanation:
The Length of an arc given is expressed as;
A = theta/360 * 2πr
10 = 45/360 * 2 * 3.14r
10 = 1/8 * 6.28r
Cross multiply
10 * 8 = 6.28r
80 = 6.28r
r = 80/6.28
r = 12.74in
Hence the radius is 12.71in
