Answer:
μ= 65 inches; σ= 0.625 inch
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed(bell-shaped) random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem, we have that:
By the central limit theorem, the sample of 16 will have:
So the correct answer is:
μ= 65 inches; σ= 0.625 inch
Answer:
24
Step-by-step explanation:
To evaluate this, we just need to substitute 2 for whenever we see x.
40 - 8 (2)
From here, we can just use order of operations to simplify it down to a single number.
40 - 16
24
So, when x = 2, we get 24.
Answer:
P = 6.4 m
Step-by-step explanation:
Hello,
The perimeter is the sum o each side of that square, so:
Psquare = 4*(lenght of side)
P = 4*(1.6m)
P = 6.4 m
PD: PI IS NOT NECESSARY, WORKS ONLY FOR CIRCLE
Best regards
Answer:
cp=2800
mp=cp+30%of cp=2800+30/100×2800=3640
discount=10%
discount amount=10%ofmp=10/100×3640=364
sp=mp-discount=3640-364=3276
vat=15%
sp with vat=sp+vat%of sp=3276+15/100×3276=3276+491.4=3767.40
The second one is correct
