What is the mean of the values in the stem-and-leaf plot?

Enter your answer in the box.

Answers

Answer:

The mean is the average of a set of data.

Example:

To find the mean, add up all of the numbers in the set and divide by the number of values that you added.

35 + 36 + 37 + 38 + 40 + 40 + 41 + 42 + 43 + 55 + 55 + 55 + 56 + 57 + 58 + 59 = 747

Answer:

64 degrees

Step-by-step explanation:

Combining the 90 degrees, x degrees, and 26 degrees creates a flat angle or 180 degrees

so first, combine 90 and 26 degrees

then subtract 116 from 180

180-116= 64 degrees

If a designer sold 2,000 units of a dress with total sales of $190,000, what was the average price of the garment?

A 36-oz bottle of water costs $2.88.

What is the cost per ounce?

Answers

I got $0.08. I did the math but I am sorry if this doesn’t help you as well.

The cost of the water bottle per ounce is $0.077.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a 36-oz bottle of water costs $2.88. The cost of 1 ounce of the bottle is calculated as,

1 OZ = 1.04 ounces

36 OZ = 36 x 1.04 ounces

36 OZ = 37.44 ounces

37.44 ounces = $2.44

1 ounce = $2.44 / 37.44

1 ounces = $0.077

there are five marbles in a bag. three are green and two are yellow. you draw a marble, replace it, and then draw another. what is the probability of choosing a green marble and then a yellow marble.

Answers

Answer: 1/10

Step-by-step explanation:

1: Let’s take out the “DO NOT REPLACE IT.” It can make the whole thing seem harder. Rather, here is this. “There are five marbles in a bag, 3/5 are green and 2/5 are yellow. You DRAW TWO MARBLES. What is the chance of you drawing two yellow marbles?”

2 : Now let’s look at some important information.

100% of marbles= 5 marbles.

60% of marbles= the three green marbles.

40% of marbles= the two yellow ones.

Picking 2 of the 5 marbles will mean taking 40% of the marbles out of the bag.

Simplify: Now, to make it easier, the question is this. what is the chances of the 40% being the same color, Specifically yellow.

3: Let me explain. There are two yellow marbles, you pick out two. That is a one out of five chance of you getting ONE yellow marble the first time. That is 1/5. picking two at the same time results in a 2/5 chance.

4: if you pick twice it would be 1/10 chance.
