The number of days ahead travelers purchase their airline tickets can be modeled by an exponential distribution with the average

agasfer [191]

Answer:P(x<10) =0

Step-by-step explanation:

M =1/μ

M= 1/15 =0.066667

X- Exp (0.066667)

Where: X is the random variable for number of days

P (X<x) = 1 - e^-mx

P(X - x) = 1 - e^-0.06666 x10

P(x<10) = 0

At what simple interest rate will an amount of money gain 50% of the principal in 4 years

tatyana61 [14]

Answer:

Simple interest only pays interest on the original amount. So, if you want your amount to grow by 50% over 4 years, you will need it to grow by 1/4 of that each year. Just divide 50% by 4 to get 12.5%.

The scores of individual students on the American College Testing (ACT) Program composite college entrance examination have a No

Margarita [4]

Answer:

Option D) At least 3600

Step-by-step explanation:

We are given the following in the question:

The distribution of scores of individual students on the American College Testing is a bell shaped distribution that is a normal distribution.

Population standard deviation =

$\sigma = 6.0$

We want that the standard deviation of the sample should not be more than 0.1 that is the standard error should not be more than 0.1

Formula for standard error:

$S.E = \dfrac{\sigma}{\sqrt{n}}$

$S.E\leq 0.1\\\\\dfrac{\sigma}{\sqrt{n}}\leq 0.1\\\\\dfrac{6}{\sqrt{n}}\leq 0.1\\\\\sqrt{n}\geq \dfrac{6}{0.1}\\\\\sqrt{n}\geq 60\\n\geq 3600$

Thus, the sample size must be atleast 3600 so that the sample standard deviation is not more than 0.1.

Thus, the correct answer is

Option D) At least 3600
