ok I got this
So we need to find the value of X so
First, we need to see which one can add up to 22
as we already know, 14+8=22
so B.8
also so yk I'm not just playing I'll even put it in a calculator and show ya
Among the students who did not make the honor roll. Then the relative frequency of having no curfew will be 7.
<h3>How to find the relative frequency?</h3>
Relative frequency is the ratio of the considered sub-group count to the total count. (so its frequency of the considered sub-group relative to the total frequency).
Curfew No Curfew No
Honor Roll: 18 10
No Honor Roll: 2 7
Among the students who did not make the honor roll.
Then the relative frequency of having no curfew will be 7.

57 - 4t > = 13.....subtract 57 from both sides
-4t > = 13 - 57
-4t > = - 44 ...divide both sides by -4, and change the inequality sign
t < = -44 / -4
t < = 11
u solve inequalities much like u do equations except for one very important rule. In an inequality, if u divide/multiply by a negative number, u have to change the inequality sign.
Based on the information given, the correct options will be:
a.) Mary would use the sample standard deviation to calculate a t-statistic.
c.) The value for the degrees of freedom for Mary's sample population is six.
One-sample t-test simply means a statistical hypothesis test that's used for the determination of whether an unknown population mean will be different from the specific value.
In this case, the value of the degree of freedom for the sample will be:
= (n - 1) = 7 - 1 = 6.
Also, it should be noted that Mary would use the sample standard deviation to calculate a t-statistic.

Answer:
D, infinitely many solutions
Step-by-step explanation:
1. multiply out
5(x-3) = 5x-15
2. combine like terms
5x-15-3x=8x-15-6x = 2x-15=2x-15
they are equal so there are infinite solutions.
