Answer:
1.66
Step-by-step explanation:
Calculation to find the standard deviation for the random variable X of the number of students who work full time in samples of size
Using this formula
Standard deviation(X)=√np(1−p)
Where,
n represent the number of students=16
p represent the percentage of all students who work full time=22
Let plug in the formula
Standard deviation(X)=√16(0.22)(1−0.22)
Standard deviation(X)=√(3.52)(0.78)
Standard deviation(X)=√2.7456
Standard deviation(X)=1.656
Standard deviation(X)=1.66 (Approximately)
Therefore the standard deviation for the number of students who work full time in samples of size 16 will be 1.66
Answer: The answer is x >7
Step-by-step explanation:
56⋅x>616−224
56⋅x>616-224
Simplify :
56⋅x>392
56⋅x>392
Dividing by the variable coefficient :
x>
392
56
x>39256
Simplify :
x>7
x>7
Inequality
56⋅x+224>616
56⋅x+224>616
is true for
x>7
x>7
Answer:
10 times.
Step-by-step explanation:
The number in the tenths place is 90. The number in the ones place is 9. 9 times 10 is 90.
