Answer:

The answer is proportions.

Step-by-step explanation:

To work backwards to find realized income needed from a given mortgage payment amount, you use proportions.

For example:

Say you are paying $1250 as monthly rent.

So, if you spend 25% of your monthly income on rent, you need a monthly income of $5000. If you can spend 30% in rent, then you will need a monthly income of $4166.66.

This way proportion is used to find the required answer.

Answer: 2sqrt(10)

Step-by-step explanation:

I'll do the top left one as an example, you can do the rest.

From the geometric mean theorem, we get that 5/x = x/8.

This rearranges to x^2 = 40

x = 40 = 2sqrt(10)

Andreyy89

Answer:

B. 21, 28, 33, 41, 81

Step-by-step explanation:

Data : 21, 22, 22, 24, 24, 24, 24, 25, 26, 26, 26, 26, 26, 26, 26, 26, 26, 27, 27, 27, 27, 28, 28, 28, 28, 29, 29, 29, 29, 29, 30, 30, 30, 30, 30, 30, 31, 31, 31, 32, 32, 33, 33, 33, 33, 33, 33, 33, 34, 34, 34, 34, 34, 35, 35, 35, 35, 35, 37, 37, 37, 37, 38, 38, 38, 39, 39, 39, 41, 41, 41, 41, 42, 42, 44, 45, 45, 45, 47, 49, 49, 54, 60, 60, 61, 61, 61, 62, 62, 74, 81

Five number summary includes :

1. Minimum vale

2. First Quartile

3. Median : mid value of the given data is 46th term = 33

4.Third Quartile

5.Maximum value

Solution :

1. Minimum vale : smallest value of data = 21

2. First Quartile: median of the data (first number to the actual median) i.e. from 1st term to 46th term

Median for even number of terms :  \frac{\frac{n}{2}th+(\frac{n}{2}+1)th}{2}

n = 46

so, median =  \frac{\frac{46}{2}th+(\frac{46}{2}+1)th}{2}

                    = \frac{23th+24th}{2}

                    = \frac{28+28}{2}

                   = \frac{56}{2}

                     = 28

Thus first quartile = 28                

3. Median : mid value of the given data(ages of 91 women) is 46th term = 33

4.Third Quartile :median of the data (46th number[actual median] to the 91th)

Median for even number of terms :  \frac{\frac{n}{2}th+(\frac{n}{2}+1)th}{2}

n = 46

so, median =  \frac{\frac{46}{2}th+(\frac{46}{2}+1)th}{2}

                    = \frac{23th+24th}{2}

                    = \frac{41+41}{2}

                   = \frac{82}{2}

                     = 41

Thus third quartile = 41

5.Maximum value : highest value of data = 81

Thus the five number summary is  21, 28, 33, 41, 81

Hence Option B is correct

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  

10

. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
