What are the mean the mode of the set of data 5,12,1,5,7

Hello There!

Mean: Average of numbers in a set of data.

STEP 1: To find the mean of these numbers, we first have to add the numbers

up and get our sum. In this case, we would add 5 + 12 + 1 + 5 + 7 = 30

STEP 2: Divide the sum by the number of digits you added. We would divide

30 "sum of the numbers" by 5 "number of digits" and we would get a quotient of 6

The mean for this set of data is 6

Mode: The number that occurs most often in a set of numbers.

Looking at our numbers, we can see that the number 5 appears twice in the set and no other numbers appear more than once. This means that our mode for our set of numbers is 5

The mode for this set of data is 5

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
