Sample size :
Mean :
Standard deviation =
Let x be a binomial variable.
Using the standard normal distribution table ,
(1)
Z score fro normal distribution:-
For x=4
For x=3
Then , from (1)
Hence, the probability that four students are absent =

Can I get brainiest please
1. Count how many men are fit to climb:
200 men - 100%
x men - 12 %
Then
2. 60 are fit enough to climb Mount Shasta in California, among them 24 are men, then 60-24=36 are women.
3. The probability that a person picked at random from the group is a male is
4. The probability that a person picked at random from the group is fit to climb Mount Shasta is
5. Use formula
6.
Then
7.
Answer: 0.472 (or in percent near 47.2%).
Answer:
f(x)= 2ˣ
We have to find x when f(x) is 8
8=2ˣ
we can write 8 in exponential form as 2³
2³=2ˣ
here base is same (2) on both left and right side
comparing the powers we get
x=3

Set it up as an equation:
m=miles she can drive
42+.35m=70
Subtract the 42, so
.35m= 28
Divide by .35, so
m=80
She can drive 80 miles
