Answer:

r=19

IQR=9

SD=5.81

Step-by-step explanation:

Given the following data set:

26, 27, 20, 15, 30, 34, 28,20

To find the range of a data set we have to find the largest and the smallest number of the set and then subtract them.

26, 27, 20, 15, 30, 34, 28,20

34-15=19

r=19

To find the interquartile range we have to subtract the third quartile by the first quartile.

26, 27, 20, 15, 30, 34, 28,20

IQR=Q3-Q1

Q1=20

Q3=29

IQR=29-20=9

IQR=9

To find the standard deviation of a data set we have to use the formula to calculate standard deviation with the given values.

SD=\frac{(26-25)^2+...+(20-25)^2}{8}

SD=\frac{270}{8} =\sqrt{33.75} =5.8094750193111

5.8094750193111

9>5

SD=5.81

Hope this helps.

MrMuchimi

Answer:

The owner says that she will work 12 hours more than you if you get the job.

We know that she works 50 hours each week.

then, knowing that she works 50 hours per week and that she works 12 hours more than you, you have that, if H is the number of hours that you work per week, you have:

H + 12 = 50

Here says that the number of hours that you work, plus 12 hours, is equal to the number of hours that the owner works.

H = 50 - 12 = 38

This means that you would work 38 hours per week.

Answer:

Histogram.

Step-by-step explanation:

Such a Graph is called Histogram.

A histogram can be defined as a visual representation of data in form of bars of different heights. In histogram, each and every bar groups numbers into ranges. The greater the height of the bar, the larger the data falls into its range. It basically represents shape and spread of continuous data sample.

How do I find the factor of the trinomial of y^2+7y-30
wel
Find two numbers that multiply to -30 (last term) and add to 7 (middle coefficient)

The two numbers are 10 and -3
10 times -3 = -30
10 plus -3 = 7

Using those two values gets us the two factors (y+10) and (y-3)

Therefore, y^2+7y-30 factors to (y+10)(y-3)

The equation y^2+7y-30 = (y+10)(y-3) is true for all values of y.
