Answer:
She need to walk 31/75 miles to school.
Step-by-step explanation:
It is given that,
Sofia has walk
miles to school. She has already walk
of a mile.
We need to find how much farther does she need to walk.
Total distance =

Let she has to walk x distance to school.

Hence, she need to walk 31/75 miles to school.
Using the arrangements formula, considering the given digits, it is found that Edward writes 6 numbers.
<h3>What is the arrangements formula?</h3>
The number of possible arrangements of n elements is given by the factorial of n, that is:

In this problem, the first digit has to be 5, while the other three are arranged, hence the total number of arrangements is given by:

A open circle means that x is < or >.
A closed circle means that x is ≤ and ≥.
--------------------------------------------------
Answer: A) x > -8 or x ≥ 5
--------------------------------------------------
Explanation: Their are two dots on the number line. One being a closed dot and the other being an open dot. The open dot symbolizes that x needs to be greater than -8. The closed dot symbolizes that x needs to be less than or equal to 5.

Answer:
The mean is 95 and the standard deviation is 2
Step-by-step explanation:
Central Limit Theorem
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 question:
Population:
Mean 95, Standard deviation 12
Samples of size 36:
By the Central Limit Theorem,
Mean 95
Standard deviation
