You can separate them so 6-4 and 1/2 - 1/7
6-4=2
1/2-1/7 you need to find a common denominator- 14
As you need to multiply 2 by 7 to get 14 you multiply the 1 by 7 to get 7/14. For the 1/7, you need to times the 7 by two to get 14 so you times the 1 by 2 to get 2/14.
So you get 7/14-2/14, because you have the same denominators you just subtract the top numbers and leave the bottom so you get 5/14. Add the 2 from earlier and your answer is 2 5/14

The true statements are:
The interquartile range is 10.
The data is skewed.
<h3>What are the true statements?</h3>
A box plot is used to study the distribution and level of a set of scores
The end of the first whisker represents the minimum number and the end of the second whisker represents the maximum number.
On the box, the first line to the left represents the lower (first) quartile. The next line on the box represents the median. The third line on the box represents the upper (third) quartile. The interquartile range is the difference between the first and third quartile.
Interquartile range = 9 - (-1) = 10
A box plot is negative skewed because the median is not at the center of the box.
An outlier would be within: (Q1 - 1.5 * IQR or Q3 + 1.5 * IQR).
- 1 - (1.5 x 10 ) = -16
9 + (1.5 x 10) = 24

Answer: The probability is 1/4
Step-by-step explanation:
The odds of rolling a 1,2, or 3 on the first roll is 3/6 or 1/2.
The odds of rolling a 4,5, or 6 on the second roll is also 3/6 or 1/2
The odds all together is 1/4 because 1/2 divided by 1/2 is 1/4.
If I’m wrong tell me
Percent means parts out of 100
120%=120/100=1.2
80%=80/100=0.8
'of' means multiply
1.2 times a=0.8 times b
a=12
1.2 times 12=0.8 times b
14.4=0.8 times b
divide both sides by 0.8
18=b
so
a=12
b=18
a+b=12+18=30
