Write an expression to represent: Nine minus the quotient of two and a number x.

Lets break it down:

I think “nine minus” is clear — it starts off with “9 - something”.

Now, a quotient is the result of division. For example, the quotient of 10/5 is 2, or the quotient of 16/2 is 8. Since in the phrase “quotient of two and x” two comes first, we are diving 2 by x. This is the quotient (2/x).

So to add it all together:

9 - 2/x would be your expression.

The number of failures of a testing instrument from contamination particles on the product is a Poisson random variable with a m

photoshop1234 [79]

Answer: 0.1353

Step-by-step explanation:

Given : The mean of failures = 0.025 per hour.

Then for 8 hours , the mean of failures = $\lambda=8\times0.25=2$ per eight hours.

Let X be the number of failures.

The formula to calculate the Poisson distribution is given by :_

$P(X=x)=\dfrac{e^{-\lambda}\lambda^x}{x!}$

Now, the probability that the instrument does not fail in an 8-hour shift :-

$P(X=0)=\dfrac{e^{-2}2^0}{0!}=0.1353352\approx0.1353$

Hence, the the probability that the instrument does not fail in an 8-hour shift = 0.1353

A toy that originally sold for 12 dollars went of sale for 8 dollars what was the percent discount? Remember to show your work!

harkovskaia [24]

12———-100%
8 ———— x
X=(8*100)/12=800/12=66.66%
Then discount percent is 100-66.66=33.33%
