Step-by-step explanation:
Just did it on edge
Solution:
As one of the fraction is a proper fraction and another one is Mixed fraction.
There are two methods of solving it.
1. 
2. ![\frac{1}{2}\times-4 \frac{4}{5}=\frac{1}{2}[-4-\frac{4}{5}]=\frac{1}{2}\times (-4)+\frac{1}{2}\times\frac{-4}{5}=-2+\frac{-2}{5}=\frac{-10-2}{5}=\frac{-12}{5}=-2\frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Ctimes-4%20%5Cfrac%7B4%7D%7B5%7D%3D%5Cfrac%7B1%7D%7B2%7D%5B-4-%5Cfrac%7B4%7D%7B5%7D%5D%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%28-4%29%2B%5Cfrac%7B1%7D%7B2%7D%5Ctimes%5Cfrac%7B-4%7D%7B5%7D%3D-2%2B%5Cfrac%7B-2%7D%7B5%7D%3D%5Cfrac%7B-10-2%7D%7B5%7D%3D%5Cfrac%7B-12%7D%7B5%7D%3D-2%5Cfrac%7B2%7D%7B5%7D)
→→Here i have used Distributive property with respect to addition and Subtraction i.e a×(b+c)= a ×b + a×c or a×(b-c)=a×b-a×c
Now, you can fill the blanks by yourself.
Answer:
the answer is 22 common value
Answer:
d. The median and the IQR
Step-by-step explanation:
The median separates the upper half from the lower half of a set. So 50% of the values in a data set lie at or below the median, and 50% lie at or above the median. This means that the median is the appropriate numerical measure to describe the center.
The first quartile(Q1) separates the lower 25% from the upper 75% of a set. So 25% of the values in a data set lie at or below the first quartile, and 75% of the values in a data set lie at or above the first quartile.
The third quartile(Q3) separates the lower 75% from the upper 25% of a set. So 75% of the values in a data set lie at or below the third quartile, and 25% of the values in a data set lie at or the third quartile.
The quartiles are used to measure the spread of a data-set.
The interquartile range(IQR), is Q3-Q1.
So the correct answer is:
d. The median and the IQR
