Answer:

0.37

Step-by-step explanation:

we have given that emails arrives at the server at the rate of 10 per hour means $\frac{10}{60}=0.166$ per minute

we have to find the probability that the time difference between the two email is more than 2 minute

so probability $P\left ( X> 2 \right )=e^{-2\lambda }=e^{-2\times 0.166}=0.7166$

A company makes video games. The price of a video game is modeled by the function p(x) = 30x + 2, where x is the number of years

atroni [7]

The answer is option C "multiplication." You have the function p(x) = 30x + 2 and x equals the number of years since the company started producing games which has this equation also s(x) = 500x + 250 in order to find the revenue from their video games the company should use the multiplication on the polynomials.

Hope this helps!

7,210 books in a library are organized into 3 rooms. there are 1,960 more books in the first room than in the second room. the n

Free_Kalibri [48]

Answer:

750 books

Step-by-step explanation:

Let there be "x" number of books in the 3rd room

Now,

2nd room has 3 times as 3rd room, so we can write:

Second Room = 3x

Also, there are 1960 MORE books in 1st room than 2nd room, so we can write:

First Room = 3x + 1960

In total there are 7210 books in all three rooms, thus we can write:

First Room + Second Room + Third Room = 7210

Now, replacing the first 2 equations in this, we get:

3x + 1960 + 3x + x = 7210

Solving for x:

$3x + 1960 + 3x + x = 7210\\7x=7210-1960\\7x=5250\\x=\frac{5250}{7}\\x=750$

"x" is indeed what we are looking for. Thus,

There are 750 books in the third room
