Answer:
96 employees
Step-by-step explanation:
Given that the standard deviation = 22.8
The width in the question = 12
We solve for the margin of error E.
E = width / 2
= 12/2 = 6
At 99%
Alpha = 1-0.99
= 0.01
Alpha/2 = 0.01/2 = 0.005
Z0.005 = 2.576
Sample size n
= ((2.576x22.8)/2)²
= 95.8
= 96
The number of employees is 96

Answer:
4.57 * 10^8
Step-by-step explanation:
457,000,000
Imagine there is a decimal point at the end like so
457,000,000.
In order to get to 4.57000000, you need to move the decimal 8 spaces left.
Thus, 457,000,000 in scientific notation is 4.57 * 10^8
<span>D. y = 20(0.75)^x,
for function to be decreasing value under exponent should be less than 1,
y(int) can be found when x=0
</span>y = 20(0.75)^0=20*1=20
Answer:
C.
Step-by-step explanation:
When you fix in the values of x from the table, you'll get y
