Answer:
X=3.33
Step-by-step explanation:
5(-3x+1)=-45
-15x+5=-45
-15x=-45-5
-15x=-50
x=3.33
Answer: 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
12/60 x 100
= 1/5 x 100
= 20%
Since Mr. Rodriguez used the data to draw the inference that about 20% of middle school students prefer to read science fiction.
So yes, he makes a reasonable inference.
