Sin(35)x14 =8.03007...
So answer is 8
Answer:
The another term for the 4% value is : Margin of error
Step-by-step explanation:
Dr. Cyril conducts a simple random sample of 500 men.
He finds that 23% of them report being unsure of their ability to be good fathers, plus or minus 4%.
Now, the another term for the 4% value is : Margin of error
Means the estimate of father being unsure about his ability would be between 19% and 27%.
When sample size is increased, the margin of error becomes smaller.
Answer:
$262
Step-by-step explanation:
Answer:
D. 4/25
Step-by-step explanation:
To find probability, you multiply 4/10 by 4/10. You should get 16/100, which simplifies to 4/25.
Answer:
2.4
Step-by-step explanation:
We would first calculate the mean, because we would need it to calculate our varance.
Mean= sum of the number of given data set/ total number
Mean = (9 +8 +9 +5 +9 )/5
= 40/5= 8
variance (σ2):= [(9-8)^2 + (8-8)^2 + (9-8)^2 +(5-8)^2 +(9-8)^2]/5
=( 1+ 0 + 1 +9 +1)/5
= 12/5
variance (σ2)= 12/5
=2.4
