You use the rules of BEDMAS so start with the brackets -[2(-17)] start with 2*-17 which is -34 then multiply -4*-5=20 so now you have 20-(-17)=37 butttt the question is asking to SIMPLIFY so you combine like terms which adds up to 37

Marina CMI [18]

Answer:

6 students are served per hour.

45.12% probability a student waits less than 6 minutes.

Step-by-step explanation:

Exponential distribution:

The exponential probability distribution, with mean m, is described by the following equation:

$f(x) = \mu e^{-\mu x}$

In which $\mu = \frac{1}{m}$ is the decay parameter.

The probability that x is lower or equal to a is given by:

$P(X \leq x) = \int\limits^a_0 {f(x)} \, dx$

Which has the following solution:

$P(X \leq x) = 1 - e^{-\mu x}$

mean of 10 minutes.

This means that $m = 10$ , so $\mu = \frac{1}{10} = 0.1$

How many students are served per hour?

One student is served each 10 minutes, on average

An hour has 60 minutes

60/10 = 6

6 students are served per hour.

Calculate the probability a student waits less than 6 minutes.

$P(X \leq x) = 1 - e^{-0.1*6} = 0.4512$

45.12% probability a student waits less than 6 minutes.

Michell bought 5 packs of crayons for $13.75 what's the coust of one pack?

Keith_Richards [23]

All you would do is divide for this problem so,

13.75 ÷ 5 = 2.75

So one pack would cost 2.75

Answer:

8 units = L

Step-by-step explanation:

The area of a rectangle is the product of length and width.

A = L*W

If A = 56 units^2 and W = 7 units, then L = (56 units^2) / (7 units) = 8 units = L
