Answer:
finding how many inches he goes in an hour (multiply by 3600)
Step-by-step explanation:
Answer: x+46
Step-by-step explanation:
For this problem, you want to first distribute each term.
4(-8x+5)-(-33x-26) [distrubute 4 and -1]
-32x+20+33x+26 [combine like terms]
x+46
⇒The Variance tells us spread between each variate in data set from mean.
Now, Coming to the Question
⇒Sample of 14 students were taken from a population of 168 students.
Variance =Expected value of square of each variate taken from mean, which can be represented as

Size of Sample taken in terms of Percentage

⇒Sample Size is Approximately only 8.4% of total Population,which is very small, that can't represent the whole Population Variance.
Option B:→ 14 , is most appropriate, which Represents the Variance of 14 student height.
1 is 3 2 is 48 4 is 5 5 is 51 6 is 27:12 7 is 15 8 is 26
12% = 12/100 = 0,12
0,12 x x = 9
x = 9/0.12
x = 75
9 is 12% of 75
