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

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

What is the distance from (23. 5) 0 (23. -12)?

Answers

The distance between (23,5) and (23,-12) is 17 units.

Because the x values are equal then this makes this problem much easier. Since y value 5 and y value -12 are in different quadrants then you would add them together (because one value is positive and one is negative). You need to add 5 and the absolute value of -12 which is 12. Adding 5 and 12 and you would get 17.

A bag holds 6 tiles: 2 lettered and 4 numbered. Without looking, you choose a tile. What is the probability of drawing a number?

Answers

The bag contains 6 tiles: 2 lettered and 4 numbered. The probability of drawing a number without looking is 2/3.

Probability is the ratio of the number of favorable outcomes and a total number of outcomes. it deals with finding out the likelihood of the occurrence of an event.

Given that,

The bag holds 6 tiles.

Among the tiles, 2 are lettered and 4 are numbered.

The task is to choose a tile from the bag without looking.

The bag contains a total of 6 tiles: 2 lettered and 4 numbered.

Therefore,

The probability of drawing a number can be calculated by dividing the number of numbered tiles by the total number of tiles.

Probability of drawing a number = (Number of numbered tiles) / (Total number of tiles)

Probability of drawing a number = 4 / 6

Simplifying this fraction, we get:

Probability of drawing a number = 2 / 3

Hence,

The probability of drawing a number from the bag is 2/3.

you take the total number as the denominator and the amount of each become your numerators.For numbered it's 4/6 then you divide both the top and bottom number by two and you get 2/3 or 66%.
