Answer:
60 degrees
Step-by-step explanation:
180 - 120= 60
Given:
The equation is
To find:
The value of b.
Solution:
We have,
Subtracting both sides by 
, we get
Therefore, the value of b is 
.
Answer:
-4/15
Step-by-step explanation:
2/5-4/6=2/5-2/3=6/15-10/15=-4/15
Answer:
x=2
Step-by-step explanation:
5(7-x)-3(x+4)-4=4(x-3)+7
35-5x-3x-12-4=4x-12+7
19-8x=4x-5
+8x. +8x
24=12x
x=2
Answer:
the average distance from the mean is:
$ 7.2
step-by-step explanation:
we are given data points as:
$7, $20 , $9 , $35 , $12 , $15 , $7 , $10 , $20 , $25 , $7 , $20 , $9 , $35 , $12 , $15 , $7 , $10 , $20 , $25
the mean of the data set is:
now we are asked to find the average distance from the mean or mad of the data.
the absolute difference of each data point from mean is calculated as follows:
|7-16|=9
|20-16|=4
|9-16|=7
|35-16|=19
|12-16|=4
|15-16|=1
|7-16|=9
|10-16|=6
|20-16|=4
|25-16|=9
|7-16|=9
|20-16|=4
|9-16|=7
|35-16|=19
|12-16|=4
|15-16|=1
|7-16|=9
|10-16|=6
|20-16|=4
|25-16|=9
the answer is: $ 7.2
