Hi!
<h3>To find the prime factorization of a number, keep dividing by the smallest factor that goes into it. </h3>
63/3 = 21
21/3 = 7
7/7 = 1
<u>3 · 3 · 7 = 63</u>
<h2>The answer is D. 3 · 3 · 7 </h2>
Hope this helps! :)

Answer:

Step-by-step explanation:
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The t distribution or Student’s t-distribution is a "probability distribution that is used to estimate population parameters when the sample size is small (n<30) or when the population variance is unknown".
The shape of the t distribution is determined by its degrees of freedom and when the degrees of freedom increase the t distirbution becomes a normal distribution approximately.
Data given
Confidence =0.99 or 99%
represent the significance level
n =16 represent the sample size
We don't know the population deviation 
Solution for the problem
For this case since we don't know the population deviation and our sample size is <30 we can't use the normal distribution. We neeed to use on this case the t distribution, first we need to calculate the degrees of freedom given by:

We know that
so then
and we can find on the t distribution with 15 degrees of freedom a value that accumulates 0.005 of the area on the left tail. We can use the following excel code to find it:
"=T.INV(0.005;15)" and we got
on this case since the distribution is symmetric we know that the other critical value is 
Hi There!
----------------------------------------------
Part A:
Slope Intercept Form: y = mx + b
m = slope (slope =
)
b = y intercept

b = 3
Answer: y = -1/2x + 3
----------------------------------------------
Part B:
Just substitue f(x) for y.
Function Notation = f(x) -1/2 + 3
----------------------------------------------
Part C:
This function given looks almost the same but the slope is different while the one stated in the question has a slope of +2 and the equation given at the start with the slope being -1/2.

Answer:
There is no clear relationship between the number of times students arrive late and the distances they live from school.
Step-by-step explanation:
By looking at the graph, there is no clear direction or association that the graph has. Therefore, there is no clear relationship between the variables being compared.
Thank you for spreading this message! Very appreciated :D I’ve never encountered one but I hope not.
