Well, since we have not actually done this experiment, we cannot use a experimental probabiltity, so we can say the correct answer is: <span>
</span><span>D. The theoretical probability is 50%.</span>

When an experiment was conducted and the results are from an actual experiment or actual data set, it is experimental probability.
When the probability is based on what is SHOULD be, as in flipping a coin should be 50% heads and 50% tails, it is theoretical probability.
One-half represents 50%. This is data from an actual club so I would say it is experimental, LETTER A.

<h3>1.) Turn each fraction into a decimal:</h3>

$1\frac{1}{2}=1.5$

$2\frac{3}{4}=2.75$

$3=3$

$2\frac{3}{4}=2.75$

$2\frac{1}{2}=2.5$

$2\frac{3}{4}=2.75$

$3\frac{3}{4}=3.75$

$3=3$

$3\frac{1}{2}=3.5$

$2\frac{1}{2}=2.5$

$3\frac{1}{2}=3.5$

Q=3(r+1)/r<br> Make r the subject of the formula

DiKsa [7]

Distribute the 3 to the parentheses. Q=3r+3/r

Next multiply both sides by r to get rid of the division sign.

Qr=3r+3

Subtract 3r on both sides and you get Qr-3r=3

Since both numbers have an r in it, we can factor out the r

r(Q-3)=3

Then we divide Q-3 on both sides

r=3 / (Q-3)

An amusement park sells child and adult tickets at a ratio of 3:1. On Saturday, they sold 63 adult tickets. How many child ticke

nalin [4]

Answer:

The number of child tickets sold by the amusement park is 189.

Step-by-step explanation:

Let A represent the number of adult tickets and C represents the number of child tickets, therefore we have:

3:1 = C:A .................... (1)

Where;

C = ?

A = 63

Substituting for the value into equation (1), we have:

3:1 = C:63

This can be converted to solve for C as follows:

3 / (3 + 1) = C / (C + 63)

3 / 4 = C / (C + 63)

0.75 = C / (C + 63)

0.75(C + 63) = C

0.75C + (0.75 * 63) = C

0.75C + 47.25 = C

47.25 = C - 0.75C

47.25 = 0.25C

C = 47.25 / 0.25

C = 189

Therefore, the number of child tickets sold by the amusement park is 189.

I am thinking of six different odd numbers, the mean of the numbers is 16, the median is 15, the range is 26, the greatest numbe

Sedaia [141]

Answer:

Step-by-step explanation:

information from the range

If the range is 26 and the largest number is 31 then the smallest number is 31 - 26 = 5

Information from the median

The median must consist of 2 numbers because we have 6 integers for the data and median must consist of the middle 2. Since we are told that the median is 15 and we need 2 integers the other integer must be 15 as well..

So what do we know so far.

5 15 15 31

Information from the mean

There are six integers making up the series of numbers. The mean is 16. Therefore all 6 integers added together must be 6 * 16 = 96

What do we have so for?

5 + 15 + 15 + 31 = 66

What do the other two numbers sum to?

96 -66 = 30

Getting the answer.

The first number to try must be 13. It has to be below 15 (the median and odd. That's 13).

So now we have

5 13 15 15 ___ 31

But from the mean we need 30

30 - 13 = 17

And we have a winner because 17 is above 15.

Answer

5 13 15 15 17 31
