Measures of variation: <span> ways to describe measures of central tendency for a data.
<em>
</em><em>the most common measure of variation is range, so in this case, the smallest number is 1, and the largest is 17. This means the range is 16.
</em>
Interquartile Range:
<em>Lower q: {1, 2, 4}
</em><em>Upper q: {8, 12, 17}
</em>Here you have to subtract 12 from 2, which gives you 10.
Mean absolute deviation:
Alright, let's first find the mean...
(1+2+4+5+8+12+17)
---------------------------= 7
7
What is the distance of each number from 7?
1: 6 units
2: 5 units
4: 3 units
5: 2 units
8: 1 unit
12: 5 units
17: 10 units
After adding all of these together, and dividing by 7, you will get...
<em>4.571428 </em></span>≈ <em>4.6 or 5.

Answer:
55.3
Step-by-step explanation:
First, take $64 and multiply it by .2.
You'll get an answer of 12.8, now subtract that from 64 to get 51.2.
Take 51.2 and multiply that by .08.
Add 4.1, (since we are rounding) to 51.2, to end with your answer: $55.30.
Answer:
x=10.4, y=5.2
Step-by-step explanation:
3:y=y:9
y^2=27
y≈5.2

Hope this helps!
Answer:

Step-by-step explanation:
using the slope-intercept formula, u have this so far as an equation (just knowing the slope): 
To find the y-intercept, substitute in the values of the coordinates given to solve for b:

so u can just put 8 into your slope-intercept formula (
) and that's it! hope this helps!
Answer:
WOW that's tough to read all squished together!!!
Jayden and Sheridan both tried to find the missing side of the right triangle. A right triangle is shown. One leg is labeled as 7 centimeters. The hypotenuse is labeled as 13 centimeters.
Jayden's Work
Sheridan's Work
a2 + b2 = c2
a2 + b2 = c
272 + 132 = c272 + b2 = 132
49 + 169 = c
249 + b2 = 169
218 = c2b2 = 120
Square root 218 equals square root c squared.
Square root b squared equals
square root 120.
14.76 ≈ cb ≈
10.95Is either of them correct?
***************************************************
In a right triangle
hypotenuse^2 = leg1 ^2 + leg2^2
13^2 = 7^2 + leg2^2
leg2^2 = 120
leg 2 = 10.9544511501
Basically, whoever said 10.95 is correct.
