Linda has a bag of marbles. She chooses a marble from the bag. writes down the color, and places the marbles back in the bag. She repeats this process 130 times. Linda calculates the relative frequency of each color marble.

Which statement about Linda's experiment is true?

A. The outcomes do not appear to be equally likely, so a uniform probability model is not a good model to represent probabilities in Linda's experiment.

B. The outcomes appear to be equally likely, so a uniform probability model IS a good model to represent probabilities in Linda's experiment.

C. The outcomes do not appear to be equally likely, so a uniform probability model is a good model to represent probabilities in Linda's experiment.

D. The outcomes appear to be equally likely, so a uniform probability model is not a good model to represent probabilities in Linda's experiment.

Answers

Answer 1

Answer:

Option: B is the correct answer.

B. The outcomes appear to be equally likely, so a uniform probability model IS a good model to represent probabilities in Linda's experiment.

Step-by-step explanation:

Equally likely outcomes--

The equally likely outcomes are the one that have equal chance or probability or likelihood of occurring.

Also, from the given relative frequency from the table we could observe that the outcomes have approximately the same relative frequency or the chances of their occurrence is almost similar.

Hence, the outcomes are equally likely.

Also a uniform probability model is one in which the outcomes have equal probability.

Hence, the statement that is true about Linda's experiment is:

Option: B

Answers

Materials = $4.25
Labor = $5.35
Sale Price = $16.99

A.) Profit = Sale Price - (Materials + Labor)
Profit = 16.99 - (4.25 + 5.35)
Profit = 16.99 - (9.60)
Profit = $7.39

Profit / Sale Price = % Profit
7.39 / 16.99
or
739 / 1699

B.) % Profit = Profit / Sale Price × 100
  % Profit = 7.39 / 16.99 × 100
  % Profit = 0.43496 × 100
  % Profit = 43.496 %
  % Profit = 43 %

C.) Total Sales = $324.86

Necklaces Sold = Total Sales / Individual Sale Price
Necklaces Sold = 324.86 / 16.99
Necklaces Sold = 19.12

**This question is absolutely ridiculous because either she made money from tips or someone either paid too much or too little**

Total Profit = Necklaces Sold × [Sale Price - (Materials + Labor)]
Total Profit = 19 × [16.99 - (4.25 + 5.35)]
Total Profit = 19 × (7.39)
Total Profit = $140.41

OR

Total Profit = 20 × (7.39)
Total Profit = $147.80

Jimmy is making a rectangular sandbox in his backyard for his son. Jimmy will be using wood to frame the sides of the sandbox. He wants the length of the sandbox to be 4 feet longer than the width. Jimmy can use no more than 60 feet of wood. What inequality can show a possible width for the sandbox?

Answers

The required possible width for the sandbox is w ≤ 13 feet.

What is inequality?

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Let w be the width of the sandbox in feet.

According to the problem, the length of the sandbox is 4 feet longer than the width, so the length can be represented as w + 4.

To find the amount of wood needed to frame the sandbox, we need to find the perimeter of the sandbox, which is the sum of the lengths of all four sides. Since there are two sides of width w and two sides of length w + 4, the perimeter of the sandbox is:

Perimeter = 2w + 2(w + 4) = 4w + 8

The problem states that Jimmy can use no more than 60 feet of wood, so we can write an inequality that represents this constraint:

4w + 8 ≤ 60

Simplifying this inequality, we get:

4w ≤ 52

w ≤ 13

Therefore, a possible width for the sandbox is w ≤ 13 feet.

Which numbers are solutions to the inequality x < −7, using the replacement set {−15, −10.5, −7.2, −7, 0}?Choose all answers that are correct.

A.
–7

B.
−7.2

C.
−10.5

D.
−15

Answers

The correct answers are B, -7.2, C, -10.5, and D, -15. The inequality x < -7 means that x is less than -7. Keep in mind that the larger a negative number appears to be, the smaller a number it actually is. For example, if you were 1 dollar in debt, then you would have more money than if you were 100 dollars in debt.

x < -7 Given
-7 < -7 Substitute for answer choice A
This inequality is untrue, because -7 is equal to -7.

-7.2 < -7 Substitute for answer choice B
This inequality is true, because -7.2 is less than -7.

-10.5 < -7 Substitute for answer choice C
This inequality is true, because -10.5 is less than -7.

-15 < -7 Substitute for answer choice D
This inequality is true, because -15 is less than -7.

Jimmy's 9th-grade class is made up of 223 students. He wants to know the average height for the students in his class, and he wants to use the census method to do this. What is the SMALLEST number of students he must measure?A) 10
B) 30
C) 100
D) 223

Answers

Answer: 223

Step-by-step explanation:

The census method is also known as a complete enumeration survey method where each and every individual in the given population is selected for the data collection.

Therefore, the SMALLEST number of students he must measure is the total number of students surveyed i.e. 223.

Hence, the SMALLEST number of students he must measure =223

I believe that the smallest number of students Jimmy can measure is 223, and I know this is right because one of my teachers had us do this probem and she said this was it.
