Answer:
-3
Step-by-step explanation:
Parallel lines have slopes that are the same.
So if one line has a slope that is -3, any line that is parallel will have the same slope

Answer:
Therefore the value of given expression when r = 14 and s = 8 is
Step-by-step explanation:
Given:
To Find:
Value of above equation when r = 14 and s = 8
Solution:
.............Given
Put,
Now 7 × 2 = 14 and 8 will cancel each other we get
Therefore the value of given expression is
16 because the length is 5 and the width is 3

Answer: For the sum of 130
First: $90
Second: $40
Step-by-step explanation:
We write equations for each part of this situation.
<u>The Total Charge</u>
Together they charged 1550. This means 1550 is made up of the first mechanics rate for 15 hours and the second's rate for 5 hours. Lets call the first's rate a, so he charges 15a. The second's let's call b. He charges 5b. We add them together 15a+5b=1550.
<u>The Sum of the Rates</u>
Since the first's rate is a and the second is b, we can write a+b=130 since their sum is 130.
We solve for a and b by substituting one equation into another. Solve for the variable. Then substitute the value into the equation to find the other variable.
For a+b=130, rearrange to b=130-a and substitute into 15a+5b=1550.
15a + 5 (130-a)=1550
15a+650-5a=1550
10a+650-650=1550-650
10a=900
a=$90 was charged by the first mechanic.
We substitute to find the second mechanic's rate.
90+b=130
90-90+b=130-90
b= $40 was charged by the second mechanic
The region that contains the most dispersed data is between the upper quartile and the median.
<h3>Which region contains the most dispersed data?</h3>
A box plot is used to study the distribution and level of a set of scores. The box plot consists of whiskers which measure the minimum and maximum numbers.
On the box, the first line to the left represents the lower quartile. The next line on the box represents the median. The third line on the box represents the upper quartile.
- Difference between the lower quartile and the median : 300 - 275 = 25
- Difference between the upper quartile and the median : 340 - 300 = 40
- Difference between the upper quartile and the maximum : 355 - 340 = 15
- Difference between the minimum and the lower quartile : 275 - 250 = 25
