Answer:
Here is the answer.
Step-by-step explanation:
b) students are the frequency. so we need to add all the frequency.
5 + 4 + 7 + 10 + 4=30 students
c) here we need to use the summation.
total/ frequency= mean
6*5=30
7*4=28
8*7=56
9*10=90
10*4=40
we need to add them all= 244
total frequency= 30
mean = 244/30= 8.133333333...≈ 8 (this is a rounded of value as in 0.13, 3 goes on repeating.

We know that the addition rule states that P(A or B) = P(A) + P(B) − P(A and B) in this problem P(A)=0.72 P(B)=0.84 P(A and B)=0.64 so P(A or B) = P(A) + P(B) − P(A and B)-----> 0.72+0.84-0.64 P(A or B) = 0.92the answer is 0.92 (92%)
8²
(8^3)(8^-2)(8^1)
=512(8^-2)(8^1)
=512(1/64)(8^1)
=8(8^1)
=(8)(8)
=64
√64=8
(8•8 so 8²)
