Answer:
4.9 units
Step-by-step explanation:
We are dealing with a Right angle triangle, and the c is actually the hypotenuse. We are given the measures of a and b.
a being 4, and b being 3.
We need to use the Pythagorean Theorem to solve this.
we can rewrite this as;
Calculation time
15 + 9 = c
c = 24
Now we find the square root of each equation to determine what is.
4 + 3 = 4.89897948557
Let's round that to the nearest tenth.
4.9 units

Answer:
Will have an expected value of the mean = 80 and a standard error of the mean = 5
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed 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:
n = 16
So the mean is 80 and the standard deviation is
Will have an expected value of the mean = 80 and a standard error of the mean = 5
