The probability that a lab specimen contains high levels of contamination is 0.12. A group of 4 independent samples are checked.

sergiy2304 [10]

Answer:

0.5996 is the probability that none contain high levels of contamination.

Step-by-step explanation:

We are given the following information:

We treat lab specimen containing high levels of contamination as a success.

P( lab specimen containing high levels of contamination) = 0.12

Then the number of lab specimens 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 find the probability that none of the lab specimen consist of high level of contamination.

We have to evaluate:

$P(x = 0)\\= \binom{4}{0}(0.12)^0(1-0.12)^{(4-0)}\\= 0.5996$

0.5996 is the probability that none contain high levels of contamination.

I wrote down 3 different positive whole numbers that add 96. the sum of any 2 is divisible by the third.

il63 [147K]

This question is really simple if you focus on this part

“The sum of any two is divisible by the third”

⟹⟹ Pairwise, the numbers must have a GCD greater than one.

Let this GCD be xx.

The first three easiest numbers I can think of are x,2xx,2x and 3x3x

Because

gcd(x,2x)=gcd(2x,3x)=gcd(3x,x)=xgcd(x,2x)=gcd(2x,3x)=gcd(3x,x)=x

The numbers sum to 9696

⟹x+2x+3x=96⟹x+2x+3x=96

⟹6x=96⟹6x=96

⟹x=16⟹x=16

The largest number is 3x=3×16=483x=3×16=48

Does anyone know how to do number 8?

Alekssandra [29.7K]

$\frac{a - 1}{7 - 7a} = \frac{a - 1}{7(1 - a)} = \frac{ - (1 - a)}{7(1 - a)} = \frac{ - 1}{7}$
for all a except a=1
which is choice 3
