Mathematics

Eva8 [605]3 years ago
5 0

Answer:

x=-32

Step-by-step explanation:

expand -2(x+10): -2x-20

x-2x -20=12

add similar elements: x-2x=-x

x-20=12

add 20 to both sides

-x-20+20=12+20

simplify

-x=32  

divide both sides by -1

x=-32

Make 2 sets of data 8 numbers each between 1 and 25. Then calculate the median and IQR for each data set.
vlada-n [284]

The median of the data set will be 15.5. The data set is in between the 1 to 25.

<h3>What is median?</h3>

Median is such a number for the arranged data set in ascending or descending order, such that to its left and to its right belong the same number of observations.

The data set between the number is;

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25

The value of IQR for data set is;

First Quartile Q1 = 6.5

Second Quartile Q2 = 13

Third Quartile Q3 =19.5

The median of the data set is;

\rm Median= \frac{15+16}{2}  \\\\ Median= 15.5

Hence, the median of the data set will be 15.5.

A)- 5x-9<br> b)- 6x+20<br> c)- 6x^2-23x+20<br> d)- 6x^2-14-9
likoan [24]
Multiply:  (3x-4)(2x-5)

This comes out to 6x^2 - 15x - 8x + 20

Combine the x terms and you'll be done.
