Answer:
3.625
Step-by-step explanation:
The formula for sample standard deviation = Population standard deviation/√n
Where n = number of random samples
Population standard deviation = 29 pounds
n = 64 male students
Sample standard deviation = 29/√64
= 29/8
= 3.625
Therefore, the Sample standard deviation = 3.625
The first statement is true Bc the number of customers are increasing between 30min and 60 min
The Max number would be 50 customers not 60. It would’ve been true if it changed it to max number of customers was at 60 mins
5 + 9 = 14
4.9 / 14 = 0.35
0.35 * 5 = 1.75
0.35 * 9 = 3.15
The answer is 1.75 / 3.75
M= 4/6
<span>4m + 10 = 14 − 2m
6m+10=14
6m=4
m=4/6

Angle DFB = (1/2)*[(arc CE)+(arc BD)]
Angle DFB = (1/2)*(84+38)
Angle DFB = (1/2)*122
Angle DFB = 61
(Angle DFB) + (angle DFE) = 180
angle DFE = 180 - (Angle DFB)
angle DFE = 180 - 61
angle DFE = 119 degrees
---------------------------------------
Final Answer is choice D) 119 degrees
