Question

A basketball weighs an average of 22 ounces, and it is possible for its weight to vary at most 0.75 ounces from this average. What's the range for a basketball's weight? Question 1 options: A) 21.25 ≤ x ≤ 22.75 B) 21.25 22.75 or x < 21.25

Answer 1

Answer: A) 21.25 ≤ x ≤ 22.75

Explanation:

Given, Average weight of basketballs = 22 ounces

It is possible for its weight to vary at most 0.75 ounces from this average.

Let x denotes the weight of the basket ball.

Then, the required range for a basketball's weight:

Average-0.75 ≤ x ≤ Average+0.75

⇒22-0.75 ≤ x ≤ 22+0.75

⇒21.25 ≤ x ≤ 22.75

Hence, the range for a basketball's weight: 21.25 ≤ x ≤ 22.75 .

Correct option: A) 21.25 ≤ x ≤ 22.75
