N(75/100)=4.5 multiply both sides by 100
75n=450 divide both sides by 75
n=6cm

For your question: "A teacher wants to investigate whether listening to music while taking a math test increases scores. He instructs half
of his 36 students to listen to music while taking a test and the other half to not listen to music during the test. To
determine who listens and who does not, the teacher identifies the two students who scored highest on the last test
and randomly instructs one to listen to music and one to not. The teacher does the same for the next two highest-
scoring students and continues in this manner until each student has their instructions. Which of the following best
describes this plan?"
The answer is D
Answer: A
Step-by-step explanation:
<em>- and - = + </em>
-8 (4 - x) = 16
-32 + 8x = 16
8x = 16 + 32
8x = 48
x = 6
Answer:
25
Step-by-step explanation:
Given the indicinal equation
5^-1/5^-3
According to one of the law of indices, if a, b, m and n are integers then;
a^m/a^n = a^(m-n)
When the base are equal, the powers will be subtracted.
Applying this formula to the given expression
5^-1/5^-3
= 5^{-1-(-3)}
= 5^(-1+3)
= 5^2
= 25
Therefore the answer is 25
