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.

I hope these answers help you! Please give me brainliest!</span>
Answer:
-8 x2
1.25 x2
x2
Step-by-step explanation:
Like terms are those which have the same variable. For example x²= x ² but x³≠x² functions having the same variable are called like terms. Terms vary with the change in exponents.
-8 x2
1.25 x2
x2
These three are like terms because they have the same variable with the same exponent.
The following are not like terms. They are unlike terms each having a different variable with a different exponent.
5 yx2
-3.4 x3
4 x
5
Like terms -8 x2 1.25 x2 x2
Unlike terms :5 yx2 -3.4 x3 4 x 5
Answer:
uhh if I did the math right i think it was 300
A is for Alexis and F is for Francisco
A = 1/6 + 1/2 + 1/2 = 1 and 1/6
F = 2/3 + 1/2 + 1/3 = 1 and 1/2
1 1/6 < 1 1/2
A < F
Francisco ate the most pie.
1/6 of cherry pie is left.
No apple pie is left.
1/6 blueberry pie is left.
Answer:
See below
Step-by-step explanation:
a) 43.8 - 38 = 5.8 yrs
b) SD = 8.9 yrs 5.8 / 8.9 = .6517 SD <u> below</u> the mean
(A z score merely shows how many standard deviations a score (age) is above or below the mean in SD units)
c) Z = - .6517 Negative because it is <u>BELOW</u> the mean ( FYI from z-score table: this is .2578 in percentage )
d) usual ( it (-.6517) is between -2 and + 2 )
