Answer:
1. range is about 2 times or double the interquartile range.
2. 2.7222
Step-by-step explanation:
Mean: 15.9583
Median: 17
Range: 12
Lower quartile: 13
Upper quartile: 18.75
Interquartile range: 5.75
<u>2. Is also know as the (MAD) or Mean Absolute Deviation of a data set.</u>
3) subtract the second equation from the first...
(x+7y=64)
-(x+3y=28)
_________
4y=36 divide both sides by 4
y=9, which makes x+7y=64 become:
x+63=64
x=1
So the solution to the system of equations is the point (1,9)
4)
Subtract the second from the first:
4x-4y=24
-(x-4y=3)
_______
3x=21 divide both sides by 3
x=7, which makes x-4y=3 become:
7-4y=3
-4y=-4
y=1
So the solution to the system of equation is the point (7,1)
Answer:
It's 15+12=27
Step-by-step explanation:
Hmm that's good
Answer:
20%
Step-by-step explanation:
65 and 78 are both multiples of 13. Divide both by 13, we get 5 and 6.
If we use 5 as our main value (100%), 6 would be 120% as adding 1 to the main number (5) increases it by 20%. So 6 is a 20% increase from 5.

Answer:
The sin(A) goes with 'a'
sin(B) goes with b
sin(C) goes with c
Each angle goes with the corresponding side to form the three fractions shown. You can break up that triple equation into smaller equations such as and and
Note: if you apply the reciprocal to all three sides, then you'll get an equivalent equation. I'm using the rule that A/B = C/D is the same as B/A = D/C.
