forsale [732]

Answer: x = 15

Step-by-step explanation:

12 = (4/5)x

3) Multiply by 5/4 on both sides.

Pepsi [2]

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

$\frac{12}{60}\times 100\\\\=\frac{1}{5}\times 100\\\\=20\%$

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

So, he makes a reasonable inference.
