Answer:
The distribution of sample averages will have a normal distribution withe mean = 100 and a stamdard deviation of 1.789.
Step-by-step explanation:
According to the central limit theorem, the mean of the distribution of sample means is equal to the population mean.
μₓ = μ = 100
The theorem goes further to explain that if samples of finite size are obtained from the population, the distribution of sample means will approximate the distribution of the population. Since the population is known to have data that is distributed normally, the distribution of sample means will have a normal distribution too.
The standard deviation of the distribution of sample means is given as the standard error of the mean,
σₓ = (σ/√n)
where σ = population standard deviation = 4
n = sample size = 5
σₓ = (4/√5) = 1.789

Answer:
C
Step-by-step explanation:
4(10^2) = 400
Check:
10x10=100 (area of 1 wall)
100× 4(the 4 walls)
4(10^2) = 400✅
I think the answer is x but I don't know I hope you get it right the answer should be d good luck
Because B is the midpoint of AC, point B divides AC into two equal segments:
AB = BC
Substitute all known values into the above equation:
x + 5 = 2x – 11
Add 11 to both sides of the equation:
x + 16 = 2x
Subtract "x" from both sides of the equation:
16 = x
We have proven that x = 16. Now we are asked to find the measure of AB. Simply substitute the known value of "x" into the equation for AB:
AB = 16 + 5
Simplify the right side of the equation:
AB = 21
The measure of segment AB is 21
I hope this helps!
