2900 dollars is placed in an account with an annual interest rate of 9%. How much will be in the account after 13 years, to the
1 answer:
Answer:
$8,890.83
Step-by-step explanation:
To find the answer we have to use this equation:
A = The total amount
P = The initial amount
R = The interest rate
T = Time
Given in the question:
A = ?
P = 2,900
R = .09
T = 13
Plug it into the equation and solve:
Therefore, after 13 years there will be $8,890.83 in the account.

Answer:
Step-by-step explanation:
Sample proportion p is the proportion of favourable numbers to total number in the sample
By central limit theorem and also approximation of binomial to normal , we have sample proportion for large number of samples will be normal
with mean = sample proportion
and std deviation =
Thus we find standard deviation of proportion sample is inversely proportional to the square of the sample size n.
It follows automatically that as sample size increases std deviation decreases.
Here from 80 sample size was made to 200
So std deviation would decrease automatically
