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

Mean: so basically you add up all the numbers (5+12+1+5+7=30) and divide the sum (30) with how many numbers there are (5) so 30/5=6

mode: mode is numbers repeated, since there are two 5's it is the mode (you may also have multiple modes)

Carol has 1 5/8 cups of yogurt to make smoothies. Each smoothie uses 1/3 cup of yogurt. What is the maximum number of smoothies

Mashutka [201]

Answer:

The maximal number of smothies that Carol can make with the yogurt is 4.

Step-by-step explanation:

Divide the number of cups Carol has by the number of cups needed to make one smoothie.

$1\dfrac{5}{8}:\dfrac{1}{3}=\dfrac{13}{8}\cdot \dfrac{3}{1}=\dfrac{39}{8}=4\dfrac{7}{8}.$

The maximal number of smothies that Carol can make with the yogurt is 4.

In the diagram below, what is the relationship between the number of triangles and the perimeter?

Eduardwww [97]

The perimeter "P" is equal to the length of the base of one triangle multiplied by the "n" number of triangles in the figure plus two times the length of another side. The equation for the perimeter is P = 5n + 14.

We are given triangles. The triangles are arranged in a certain pattern. The length of the base of each triangle is equal to 5 units. The length of the other two sides is 7 units each. We conclude that all the triangles are isosceles. We need to find the relationship between the number of triangles and the perimeter of the figure. Let the perimeter of the figure having "n" number of triangles be represented by the variable "P".

P(1) = 14 + 5(1)

P(2) = 14 + 5(2)

P(3) = 14 + 5(3)

We can see and continue the pattern. The relationship between the perimeter and the number of triangles is given below.

P(n) = 14 + 5n

Answer:

System is given below

Step-by-step explanation:

Let (applicable to all three lines below)
Hard candy = x kg with price $1.60/kg
Gummy worms = y kg with price $2.20/kg
Total weight = 50 kg with mixed price $1.75/kg

Required equations:

x + y = 50 total weight
1.60x + 2.20y = 50*1.75 total price

=========================================

Note. It says don't solve but the solution below for those who is interested to know the answer.

Simplify the second equation and solve by substitution x = 50 - y:

1.6(50 - y) + 2.2y = 87.5
80 - 1.6y +2.2y = 87.5
0.6y = 7.5
y = 7.5/0.6
y = 12.5

Find the value of x:

x = 50 - 12.5 = 37.5

Hard candy = 37.5 kg and gummy worms = 12.5 kg
