0.29m+10=0.35m

0.29m-0.29m+10= 0.35m-0.29m

10=0.06 m

Divide by 0.06 for 10 and 0.06

10/0.06= 0.06/0.06 m

m= 166.66666

Answer is m = 166.66666- the number 6 continues

What percent of 75 is 24?

Scilla [17]

Answer:

<h2>Your Answer is 32%</h2>

Explaination:

We already have our first value 75 and the second value 24. Let's assume the unknown value is Y which answer we will find out.

We already have our first value 75 and the second value 24. Let's assume the unknown value is Y which answer we will find out.As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

STEP 1 >> Y = 24

75

STEP 2 >>

24 × 100 = 32

75 × 100 100

STEP 3>> Y = 32%

Finally, we have found the value of Y which is 32 and that is our answer.

You can use a calculator to find what percent of 75 is 24, just enter 24 ÷ 75 × 100 and you will get your answer which is 32.

Please help me find the area of this shape

Sloan [31]

Answer:

73.5 cm²

Step-by-step explanation:

Find the area of the rectangle:

A = (3 + 12)*7 = 15*7 = 105 cm²

Find the area of triangles:

A = 1/2(3 + 15 - 9)*7 = 1/2*9*7 = 31.5 cm²

Find the shaded area:

A = 105 - 31.5 = 73.5 cm²

In a quiz contest, Mary answers 90% of the questions correctly without any additional clues from the quiz coordinator. The rando

marishachu [46]

To solve this problem, we should note that there are:

total questions = 100

questions answered correctly = 90

questions that needed additional clues = 10

1. The first question is to find the probability that in the third question, Mary would need additional clue. Therefore this implies that in the first and second questions, Mary would answer it correctly. Therefore:

Probability = (question 1 answered correctly) * (question 2 answered correctly) * (question 3 needed clue)

Probability = (90/100)*(89/99)*(10/98)

Probability = 0.08256 = 8.26%

2. The second question finds for the probability that two consecutive needs additional clue, therefore:

Probability = (question 1 needed clue) * (question 2 needed clue)

Probability = (10/100)*(9/99)

Probability = 9.1*10^-3 = 0.91%

Fine the lower and upper quartiles and interquetile range.

Gnom [1K]

Answer:

Lower Quartile = 25.5

Upper Quartile = 61.5

IQR = 36

Step-by-step explanation:

Given data is:

5, 12, 17, 23, 28, 31, 37, 41, 42, 49, 54, 58, 65, 68, 73, 71

The lower quartile is the first quartile and upper quartile is the third quartile.

A median divides the data set in two equal halves.

Lower quartile also known as first quartile is the middle value in the first half.

The first half is:

5, 12, 17, 23, 28, 31, 37, 41

As the number of values is even, the quartile will be the average of two middle values

$Q_1 = \frac{23+28}{2} =\frac{51}{2}= 25.5$

Upper quartile is the average of middle two values in the second half when the number of values is even.

42, 49, 54, 58, 65, 68, 73, 71

$Q_3 = \frac{58+65}{2} = \frac{123}{2} = 61.5$

Interquartile range is the difference of third quartile and first quartile

$IQR = Q_3 - Q_1 = 61.5-25.5=36$

Hence,

Lower Quartile = 25.5

Upper Quartile = 61.5

IQR = 36
