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
First off, you have to make 65 % into an actual number, which is 0.65 (every time you want to convert percentages into numbers, you have to divide that by 100)
Now
0.65 * 8700 = 5655
Answer: 5655
Use the given equation and solve for C.
F = 9C/5 + 32
F - 32 = 9C/5
5(F-32) = 9C
C = 5(F-32)/9
Answer:
x=8cm
Step-by-step explanation:
32=4x
divide both sides by four to get 8=x
32/4=8
4x/4=x
8=x
The height of the ramp of Raúl is calculated as; 8ft
<h3>How to use the principle of similar triangles?</h3>
Both big and small triangles are similar triangles because all three of their corresponding angles are congruent.
Now, to get the height we will use the concept of similar triangles to get;
h/2 = 12/3
Cross multiply to get;
h = 24/3
h = 8 ft
Thus, the height of the ramp of Raúl is 8ft.
