47 X 4 = 188. That is 50 too many legs. 50/2=25. If you take away 25 sheep and add 25 chicken you have the correct number of legs. There are 25 chicken and 22 sheep.
Answer:
65.5%
Step-by-step explanation:
Arrival rate, λ = average number of customers per hour = 38
Servive rate, μ = number of customers attended to per hour = 58
Utilization factor, ρ = λ / μ
ρ = 38 / 58
ρ = 0.6551724
Utilization rate (%) = 0.6551724 * 100% = 65.5%
Answer:
pls mark me as brainliest
Step-by-step explanation:
Using the normal distribution, it is found that x = 3.5 has a z-score of -2, which means that it is 2 standard deviations below the mean.
--------------------------------
In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:
The z-score measures how many standard deviations the measure X is from the mean, above or below.
X∼N(6.5,1.5), which means that .
The measure is
The z-score is:
The measure x = 3.5 has a z-score of -2, which means that it is 2 standard deviations below the mean.
