Answer:
for n = 3
for n = 10
Step-by-step explanation:
from the question we are that
The number of applicant is n
The number of people on the committee is
Generally given that the applicant ranking is random the probability of a candidate being accepted is mathematically represented as
Now for n = 3
Now for n = 10
5 5/16 is greater.
You can find that out by dividing 5/16 and 7/24
So that gives .31 and .29
Thus, 5 5/16 are greater
Answer:
Step-by-step explanation:
The probability distribution of sampling distribution is known as it sampling distribution.
The mean and standard deviation of the proportion is given by :-
, where p =population proportion and n= sample size.
Given : According to a survey, 50% of Americans were in 2005 satisfied with their job.
i.e. p = 50%=0.50
Now, for sample size n= 1000 , the mean and standard deviation of the proportion will be :-
Hence, the mean and standard deviation of the proportion for a sample of 1000:
Answer: t ≈ 20 years
Step-by-step explanation:
Since it is compounded continuously , we will use the compound interest formula:
A = P
Where A is the amount when tripled
P is the initial amount
r is the rate
t is the time
since the investment is tripled , it means the A = 3P.
From the question:
A = 3P
P = $6000
r = 5.5%
t = ?
Substituting into the formula , we have
3P = P , that is
3(6000) = 6000
Dividing through by 6000 , we have
3 =
Take the In of both sides in order to remove the exponential , that is
In 3 = 0.055t
divide through by 0.055
t = In 3 / 0.055
Therefore :
t = 19.97476888
t≈ 20 years
It would be: 3.78/1
Substitute for Unit values. That's all
