<u><em>Answer: </em></u>

Median : 23

Mode: 11 and 24

Range: 28

<u><em> </em></u>

<u><em>Step-by-step explanation: </em></u>

A stem-and- leaf plot is a very special table where each " value" is split into a stem.

Basically the stem is the foirst value of the number and the leaves are the last digits.

Example: A stem of 1 and a leaf of 1 has a value of 11.

A stem of 1 and a leaf of 2 has a value of 12.

In this case the numbers in the plot are:

11, 11, 12, 13, 14, 15, 22, 23, 24, 24, 27, 32, 35, 37, 39

The questions are :

<u><em> </em></u>

<u><em>1. What is the median? </em></u>

<u><em>2. What is the mode ? </em></u>

<u><em>3. What is the range ? </em></u>

To answer the first question, you need to list them in order.

Then find the center of those numbers. Cross out one number from the left and the right and keep doing it until there is only one ot two numbers.

One number- that is the median

two numbers left - find the mean of the two numbers and that is the median

So in this case the median is 23 crossing out seven numbers on each side.

To answer the second question, you need to find the number that comes up the most. In this case, 11 and 24.

To answer the third and last question, you need to find the mininum value and the maximum and find the difference.

In this case, 11 and 39, the difference is 28.

this week maddie worked 2 1/2 hours on monday, 2 2/3 hours on tuesday and 3 1/4 hours on wednesday. how many more hours will mad

For this you will have to know how to add fractions. First of all i like to add the whole numbers together first, so 2+2+3= 7. so now what you have to do is add the fractions together. so 2/3 + 1/4 + 1/2 = ? you will have to find a common denominator for 3, 4, and 2; which is 12. Multiply each fraction by the needed number to get each denominator to 12. so 2/3 will be multiplied by 4, 1/4 will be multiplied by 3, and 1/2 will be multiplied by 6. The new equation and answer will be: 8/12 + 3/12 + 6/12 = 17/12. 17/12 as a mixed fraction is 1 5/12. now we add 1 5/12 and 7 to equal 8 5/12. and then you will have to subtract this from 10, using common denominators and such to get your final answer of 2 1/12. (sorry for the long spiel on how to do this question)

The figure below shows two half-circles at the ends of a rectangle with the dimension shown.

timurjin [86]

Answer:

D. 154

Step-by-step explanation:

The area of the rectangle is 15*5= 75 inches

The area of the 2 semicircles combined, which make a circle, are:

π*r², where r is 5

r²=25

π*25=78.53981633

75 + 78.53981633 is about 154
