<h3><u>Answer:</u></h3>

The correct answer is:

<em>d.  the middle quartile is the median of the data.</em>

<h3><u>Step-by-step explanation:</u></h3>

We know that the median of data is the measure of central tendency.

The median is also the number that is halfway into the set.

We know that we divide the quartiles into three parts :

Lower QuartileQ_1, Upper QuartileQ_3 , Middle QuartileQ_2.

Where the middle quartile is the median of the data which is basically calculated as arranging the data in the ascending or descending order and then finding the middle value of the data.

Hence, to find the middle quartile of a box-and-whisker plot:

d. the middle quartile is the median of the data.

PLEASE HELP I’M SO CONFUSED
bekas [8.4K]

Answer:

a. $45 an hour

b. 5.25 hours

Step-by-step explanation:

a. The plumber charges $75 per job, so it is irrelevant to the number of hours they work. 45(h) is $45 multiplied by the number of hours they work.

b.

First, plug the numbers into the equation, the cost being C(h):

311.25 = 45(h) + 75

Next, subtract $75 as it is a set price that is always payed:

236.25 = 45(h)

Then, divide both sides by 45 to find how many hours were worked:

h = 5.25

Hours = $5.25

Subtract. 5x^2-5x+1-(2x^2+9x-6)
Talja [164]
<h2>Hello!</h2>

The answer is:

3x^{2} -14x+7

<h2>Why?</h2>

To solve the problem we need to add/subtract like terms. We need to remember that like terms are the terms that share the same variable and the same exponent.

For example, we have:

x^{2} +2x+3x=x^{2} +(2x+3x)=x^{2}+5x

We have that we were able to add just the terms that were sharing the same variable and exponenr (x for this case).

So, we are given the expression:

5x^2-5x+1-(2x^2+9x-6)=5x^{2}-2x^{2}-5x-9x+1-(-6)\\\\(5x^{2}-2x^{2})+(-5x-9x)+(1-(-6))=3x^{2}-14x+7

Hence, the answer is:

3x^{2} -14x+7

Have a nice day!
