Answer:

(A 40

Step-by-step explanation:

First, order the data set from least to greatest...

9, 10, 13, 15, 16, 32, 48, 51, 53, 60, 64

Note: (it already has that step done for us.)

Next, find the median-which is the middle number of the data set.

The Median is 32.

Then, find the Lower and Higher Quartile Range.

13 and 53.

Finally, subtract them from each other to get the interquartile range

The answer would be 40.

Therefore, the interquartile range is 40.

Answer:

A: -41/9

Step-by-step explanation:

Substitute the point (4, -5) and slope -1/9 into the equation y = mx + b.

-5 = -1/9(4) + b

-5 = -4/9 + b

Solve for b:

b = -41/9

Our equation: y = -1/9(x) - 41/9

Solve the following equation show your work 3{-x + (2x + 1)} = x - 1

Reika [66]

Answer:

x = -2

Step-by-step explanation:

For this problem, we must simply solve for x. To do this, we will need equation operations, and the use of the distributive property.

Let's work this line by line until we have the value for x:

3{-x + (2x + 1)} = x - 1

3*-x + 3*(2x + 1) = x - 1

-3x + 6x + 3 = x - 1

3x + 3 = x - 1

2x = -4

x = -2

Now we can check our answer for x by plugging back into the original equation and see if the left hand side is equal to the right hand side:

3{-x + (2x + 1)} = x - 1

3{-(-2) + (2(-2) + 1)} ?= (-2) - 1

3{2 + (-4 + 1)} ?= -3

3{2 + (-3)} ?= -3

3{-1} ?= -3

-3 == -3

Thus, we have found the solution for x to be equivalent to negative 2.

Cheers.

Supervisor: "Because you are working a late shift, you will get an increase in your wage. You will get an additional 10% per hou

rewona [7]

Answer:

I will make <u>$ 13.20</u> per hour

Step-by-step explanation:

Given:

Employee gets money for Working from 2.00 PM to 6.00 PM = $\$ 12$ per hour

Employee gets money for working from 6.00 PM to 12.00 AM will get additional 10 $\%$ = $\frac{10}{100}\times12= \$ 1.2$ per hour

Employee gets money for working from 12.00 AM to 01.00 AM will get additional 15 $\%$ = $\frac{15}{100}\times12= \$ 1.8$ per hour

Solution:

Employee works from 2.00 PM to 12.00 AM= Employee gets money for Working from 2.00 PM to 6.00 PM + 10 $\%$ extra wage = $\$ 12 + \$ 1.2 = \$ 13.2$
