Answer:
e) The mean of the sampling distribution of sample mean is always the same as that of X, the distribution from which the sample is taken.
Step-by-step explanation:
The central limit theorem states that
"Given a population with a finite mean μ and a finite non-zero variance σ2, the sampling distribution of the mean approaches a normal distribution with a mean of μ and a variance of σ2/N as N, the sample size, increases."
This means that as the sample size increases, the sample mean of the sampling distribution of means approaches the population mean. This does not state that the sample mean will always be the same as the population mean.
Answer:
225 milliliters
Step-by-step explanation:
Marianne tried to drink a slushy as fast as she could. She drank the slushy at a rate of 4.5 milliliters per second. After 17 seconds 148 5 milliliters of slushy remains. how much slushy was originally in the cup?
let x = slushy originally in the cup
total slushy consumed in 17 seconds = 17 x 4.5 = 76.5 ml
x - 76.5 = 148.5
collect like terms
x = 148.5 + 76.5
x = 225 ml
Answer:
78.5398 cm^2
Step-by-step explanation:
r = 1/2*d => d = 10 cm
r = 5
A = pi*r^2
= pi*5^2 => 3.1415*5^2
=> 78.5398
Hi there!
nickels:19
We know that there is only nickels and dimes in his coin collection..
<u><em>1.Multiply two terms:</em></u>
<u><em /></u>
<u><em>·</em></u>
<u><em /></u>
<u><em>Then there would be 20 nickels but 1+1=2 not 2.05.</em></u>
<u><em>2.Multiply the terms:</em></u>
<u><em /></u>
<u><em>·</em></u>
<u><em /></u>
<u><em /></u>
<u><em>·</em></u>
<u><em /></u>
<u><em>3.Combine the two terms:</em></u>
<u><em /></u>
<u><em /></u>
Therefore, there would be 19 nickels...
