Mr. rodriguez asked 60 randomly chosen students from each grade level at willowbrook school about their favorite types of reading materials. of those 60 students, 12 chose science fiction. mr. rodriguez used the data to draw the inference that about 20% of middle school students prefer to read science fiction. if 150 students attend the school, did he make a reasonable inference? explain.

Yes, he makes a reasonable inference.

Step-by-step explanation:

Since we have given that

Number of students = 60

Number of chosen science students = 12

Percentage of students who chose science is given by

Since Mr. Rodriguez used the data to draw the inference that about 20% of middle school students prefer to read science fiction.

So, he makes a reasonable inference.

Step-by-step explanation:

Evaluate the following, when a = –5 and b = 5.

Replace the value of 'a'  and b in the given expression

a^3 is (-5)^3 = -5 times -5 times -5 = -125

b^2 is (5)^2 is 25

b^3 is (5)^3 is 125

a^2 is (-5)^2 = 25
