Answer:
--- Mean absolute deviation of educational documentary
--- Mean absolute deviation of prime time drama
Step-by-step explanation:
Given
See attachment for table
Required
Determine the mean absolute deviation of each
Mean absolute deviation m(x) is calculated as:
For Educational Documentary
First, calculate the mean
So:
The mean absolute deviation is then calculated as:
For Prime time Drama
First, calculate the mean
So:
The mean absolute deviation is then calculated as:
Answer:
32 minutes
Step-by-step explanation:
all you have to do is know that the unit rate is 4 so multiply 8 and 4 to get 32
Answer:
74
Step-by-step explanation:
Answer:
x=1
Step-by-step explanation:
55+70=125
sum of angles in a triangle is 180 so
180-125=55
54x+1=55
x=1
Answer:
4 hours
Step-by-step explanation:
The amount remaining at the end of each hour is 0.85 of the amount at the start of the hour. You want to find the exponent such that ...
... 0.85^x = 0.5 . . . . . x = the number of hours until half is left
... x·log(0.85) = log(0.5) . . . . . take the log to turn it to a linear equation
... x = log(0.5)/log(0.85) ≈ 4.265024
Rounded to the nearest hour, x = 4.
