60=4/5x
4/5=0.8
60/0.8=75
X=75
Answer:
The probability that the center will have enough employees to handle this call volume is 0.2764
Step-by-step explanation:
Probability is defined as the ratio of favorable outcomes to the total number of outcomes.
Here the total mean expected number of outcomes=u = 4000
The favorable expected outcomes are = x= 22* 178= 3916
The standard deviation= σ= 5
The random variable X =178 has normal distribution with mean 4000/22 and standard deviation 5
So z= x-u/σ
Z= (3916-4000)/22/5
z= -0.764
From the table of areas under normal curve
P ( x= 3916)= P( -0.764 ≤ Z≤ 0)
P ( x= 3916)= 0.2764
The probability that the center will have enough employees to handle this call volume is 0.2764
The answer to this is D or at least that's what I got
Answer:
6 2/3 x 1 1/2 is 10
Step-by-step explanation:
Answer:
x = 54
Step-by-step explanation:
The 2 angles shown are vertical angles, so they are equal.
2x + 2 = 3x - 52
2x - 3x = -52 - 2
-x = -54
x = 54
They are 110° angles
