Answer:
The answer to your question is: V = 5x² + 40x + 80
Step-by-step explanation:
Formula = V = r²h
r = x + 4
h = 5
Substitution
V = (x + 4 )² 5
V = (x² + 8x + 16)5 expand
V= 5x² + 40x + 80 simplify
Answer:
b. No
Step-by-step explanation:
Binomial approximation to the normal:
Binomial distribution has n trials, with p probability.
If
and , it can be approximated to the normal distribution.
Assume the probability that a given student will not pass their college placement exam is 98%.
This means that
134 students:
This means that
Necessary conditions:
Since the necessary condition n(1-p) < 10 is not satisfied, the answer is No, given by option b.
Answer:
496.6
Step-by-step explanation:
circumference of circle=8pie^2
2*pie*r=8*pie^2
2*r=8*pie
2r=8*22/7
r=176/7÷2
r=12.57
Area of circle=pie*r^2
=22/7*12.57^2
=22/7*158
=496.6
