Answer:
a) 151lb.
b) 6.25 lb
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, a large sample size can be approximated to a normal distribution with mean and standard deviation 
.
In this problem, we have that:
So
a) The expected value of the sample mean of the weights is 151 lb.
(b) What is the standard deviation of the sampling distribution of the sample mean weight?
This is 
So Boris has to pay:
10% * 8190 = 819
50% * 662 = 331
50% * 188 = 94
so in total he pays: 819 + 331 + 94 = 1244
deducted each week is (52 weeks in a year):
1244/52 = 23.92
so each week $23.92 are deducted from his paycheck
Answer:
C
Step-by-step explanation:
(4,200 - 725) + 215 + 375 = 4065
I WAS THE FIRST TO PUT THIS, so if someone says the same, they copied me
Sofia slept 546 miles and was awake for 45% which is 294 of the miles.
You can find this by finding 1%, and that would be 8.4. (You get 1% from dividing 100 from the 100% number.) Then you multiply it by 65 so now you get 546.
