Answer 1

They are equals, but, they can be used as a percentage for an amount. For example

There are three numbers that are their own cube roots. What are the numbers?

Answers

The 3 number should be: 0, 1 and -1.

Final answer:

The three numbers that are their own cube roots are 0, 1, and 8.

Explanation:

The three numbers that are their own cube roots are 0, 1, and 8.

A cube root of a number is a value that, when raised to the power of 3, gives the original number. For example, the cube root of 8 is 2 because 2³ = 8. Similarly, the cube root of 0 is 0 and the cube root of 1 is 1.

So, the numbers that are their own cube roots are 0, 1, and 8.

The first quartile of a data set is 23, the median is 30, the third quartile is 33, and an outlier is 6. Which of these data values would be represented by a point in a modified box plot?

A. 30
B. 23
C. 6
D. 33

Answers

c. the outlier will most likely be the answer to this question

Answer: C. 6

Step-by-step explanation:

A box-plot mainly represents a five number summary of :

1) lowest data value 2) largest data value 3) first quartile 4) second quartile (Median) 5) third quartile.

The modified version of box-plot displays the outliers of the data by a point if present,

Since 6 is the outlier of the data.

Therefore the 6 is the value which would be represented by a point in a modified box plot.

Janine wishes to conduct a poll to predict how many dance club members will vote for her for club president.

Which polling methods are likely to be biased?

Select each correct answer.

A. Five of Janine's friends are selected and asked for whom they intend to vote.

B. From a list of all club members, 25 members are selected at random and asked for whom they intend to vote.

C. Janine chooses 5 members that plan on voting for her and asks each to select another 5 members. These 25 members are asked for whom they intend to vote.

D. Every 10th club member from a list of all members is selected and asked for whom the member intends to vote.

Answers

"Bias" means someone shows inclination towards someone or something because of the relationship that person has with that thing or person.

In this case, since Janine has friends that are also in the dance club, they are more likely to vote for her as president because they are friends with her. So, answer A is likely to be biased because the five people sampled are her friends.

Answer C is also biased because the sample chosen already plan on voting for her as president, and they are more than likely to find others who plan to vote for her.

Answer:

The answer is A & C

Somebody Really Help On These Questions 5 and 6!!!!!!!!!!!!!!!

Answers

The first question is.
6 + 6 = 12
n is the same thing on both sides of the equation
6 + 6 - n = 12 - n
You are taking an equal amount off both sides so the left and right sides are both equal still. Try it. Let n = 0.5

6 + 6 - 0.5 = 12 - 0.5
6 + 5.5 = 11.5
11.5 =? 11.5
They are both equal. In algebra a letter in an equation like this one can't change values if that letter is on opposite sides of the equation.

Write a algebraic expression for the quotient of 300 and sum of b and 24

Answers

The algebraic expressions would be 300/(b + 24). The important thing to note here is that you have a dividend and a divisor in a division problem. The first piece of info (300) is the dividend, the numerator if you are writing it in fraction form or the first number when using the standard division sign. The divisor is the SUM OF b + 24 which means you need to find the answer before dividing by it. To show that you will add first, place a parentheses around it. This is an expression, so there should be NO equals sign. It is not a complete sentence.

The algebraic expressions for the quotient of 300 and sum of b and 24 would be; 300/(b + 24).

Rectangle A has side lengths of 6 cm and 3.5 cm. The side lengths of rectangle B are proportional to the side lengths of rectangle A.
What could be the side lengths of rectangle B?

A. 3cm and 1.75cm
B. 5cm and 2.5cm
C.7 cm and 7cm
D. 12cm and 5 cm
E. 5.25cm and 9cm

Answers

To determine whether or not these are proportional, take the two side lengths that are given and create a ratio. 6cm:3.5cm. I suggest writing this in fraction form to better see the equivalency. If you divide both 6cm and 3.5 cm by 2, you create an equivalent ratio of 3 cm:1.75cm. This is answer A. There is another correct answer too! If you take 6cm:3.5cm and multiple both by 1.5, it will create an equivalent ratio of 9cm:5.25 cm (answer choice E), just in a different order.

Hello,

If you are starting with C as point (1, 1) all you have to do is multiply the coordinates by the scale factor. In this case, the scale factor is 0.25.

So we have: 0.25 x 1 = 0.25

Our new point C' will be (0.25, 0.25)
