A survey of people regarding their favorite flavor of ice cream shows 60% prefer chocolate ice cream, 30% prefer vanilla, and 10% prefer other flavors. If 86 people were surveyed in total, how many prefer vanilla? Round to a whole number.

Answers

Answer 1
Answer:

26 people would prefer vanilla out of 86 people

Step-by-step explanation:

The percentage is calculated by multiplying the quantity with rate of percentage

Given

Total people surveyed = 86

We have to calculate the number of people who prefer vanilla

The percentage of people who prefer vanilla = 30%

So,

No.\ of\ people\ who\ prefer\ vanilla = 30\%\ of\ 86\n= 0.30 * 86\n= 25.8

Rounding off to the nearest whole number: 26

So,

26 people would prefer vanilla out of 86 people

A town in east Texas received 10 inches of rain in two weeks. If it kept raining at this rate for a 31-day month, how much rain did the town receive?

Answers

If it rained 10 inches in 14 days, then it seems that it rained 10/14 or 5/7 inches of rain per day hypothetical. And since you want to see how many inches it rained in 31 day, multiply 5/7 by 31 and you get about 22.1 inches of rain. Hope this helps. 

Ellie and heather drew floor models of their living rooms. Ellie's model represented 20 feet by 15 feet. Heathers model represented 18 feet by 18 feet. Whose floor model represents the greater area? How much greater?

Answers

Answer:

Heather's model has greater area by 24 sq.ft.

Step-by-step explanation:

Given : Ellie's model represented 20 feet by 15 feet.

           Heather's model represented 18 feet by 18 feet.

To Find: Whose floor model represents the greater area? How much greater?

Solution:

Length of Ellie's model = 20 feet

Width of Ellie's model = 15 feet

Area = Length * Breadth

       = 20*15

       = 300ft^2

Length of Heather's model = 18 feet

Width of Heather's model = 18 feet

Area = Length * Breadth

       = 18*18

       = 324ft^2

Thus Heather's model has greater area by (324-300)= 24 sq.ft.
Heather's model is 324 square feet and Ellie's is 300 square feet. Therefore Heathers models is 24 square feet more than Ellie's model.

A supermarket has found that 60% of their customers spend more than $75 each visit. Whats the probability that the next 2 customers will each spend more than $75? ×

Answers

Answer: 0.36 or 36%
60%=60/100=0.6

60% is the same as saying 60/100 or 0.6

To solve for the probability of this problem, we have to, multiply the odds of the two separate events together

event1 is a customer that spends more than 75$. The odds of that happening are .6

event 2 is a customer that spends more than 75$. The odds of that happening are .6

probability=event1*event2
probability=.6*.6 
probability=.36 or 36%

Last school year the enrollment of Genoa Middle School was 465 students. This year the enrollment is 525. What is the percent of change rounded to the nearest whole?

Answers

Okay since the numbers increased, these are the steps to find the percentage.
1: find the difference between the 2 numbers. So 525- 465 = ?
2: divide the answer you got in # 1 by the original number which is 465.
3: multiply the answer you got in number 2 by 100.
4: add a percent sign at the end of your answer in #3 and there ya go. (:
Technically I think its is 99% because 525+465= 990 so in fraction it would be 990/ 1000 so if u take out a zero itwould be 99/ 100 so it would be %90
