In a random sample of 250 frozen pepperoni pizzas of a particular brand, 7 do not have enough pepperoni slices. At this rate, how many of 12,000 frozen pepperoni pizzas of the same brand will not have enough pepperoni slices?
Q. In a random sample of 250 frozen pepperoni pizzas of a particular brand, 7 do not have enough pepperoni slices. At this rate, how many of 12,000 frozen pepperoni pizzas of the same brand will not have enough pepperoni slices?
Problem Understanding: Understand the problem.We are given a sample rate of pizzas without enough pepperoni slices and need to apply this rate to a larger quantity of pizzas.
Finding the Rate: Find the rate of pizzas without enough pepperoni slices in the sample.Rate = Total number of pizzas in the sampleNumber of pizzas without enough pepperoniRate = 2507
Calculating Expected Number: Calculate the expected number of pizzas without enough pepperoni slices in 12,000 pizzas.Expected number = Rate × Total number of pizzasExpected number =(2507)×12,000
Performing the Calculation: Perform the calculation.Expected number = (2507)×12,000Expected number = (7×12,000)/250Expected number = 84,000/250Expected number = 336
