Cady's cats often share a carton of cat milk. Sammy always drinks 1/3 of the carton, tommy drinks 5/12 of the carton and Suzi dr

juin [17]

Start by making the denominators equal.

1/3 becomes 4/12
1/6 becomes 2/12
and you have 5/12.

Add together to get 10/12.

Once simplified, the answer should be 5/6.

Answer:

P(x = 0) = 0.004

P(x = 0) = 0.047

P(x = 0) = 0.211

P(x = 0) = 0.422

P(x = 0) = 0.316

Step-by-step explanation:

We are given the following information:

We treat a person who does not become a repeat offender as a success.

P(Success) = P(person who does not become a repeat offender) = 0.75

Then the number of people follows a binomial distribution, where

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 4

We have to evaluate:

$P(x = 0)\\= \binom{4}{0}(0.75)^0(1-0.75)^4 = 0.004$

$P(x = 1)\\= \binom{4}{1}(0.75)^1(1-0.75)^3 = 0.047$

$P(x = 2)\\= \binom{4}{2}(0.75)^2(1-0.75)^2 = 0.211$

$P(x = 3)\\= \binom{4}{3}(0.75)^3(1-0.75)^1 = 0.422$

$P(x = 4)\\= \binom{4}{4}(0.75)^4(1-0.75)^0 = 0.316$

Answer:

$0.002403$ $= 2.403 * 10^{-3}$

Step-by-step explanation:

Given

$0.002403$

Required

Express as scientific notation

The rule of scientific notation is that:

It is represented in form of: $a * 10^n$ where $1 \le a \le 10$

$0.002403$ will be represented as: a = 2.403; notice that the point was shifted forward by 3 units.

So:

n = -3

The equation becomes:

$a * 10^n$

$0.002403$ $= 2.403 * 10^{-3}$

Approximate

$0.002403$ $= 2.4 * 10^{-3}$

Can one fifth be simplified

Svetradugi [14.3K]

No, and never, cus there ain't any numbers that are greater than 1 that can go into both of them.
so basically if the numerator is 1, you can't simplify it anymore. Is Impossible.
