Answer: The required simplified form of the given expression is $5y^2-4y-14.$

Step-by-step explanation: We are given to simplify the following expression :

$E=2(3y-7)-5y(2-y).$

To simplify the given expression, we need to evaluate the bracket first.

The simplification is as follows :

$E\\\\=2(3y-7)-5y(2-y)\\\\=6y-14-10y+5y^2\\\\=5y^2-4y-14.$

Thus, the required simplified form of the given expression is $5y^2-4y-14.$

2(3y - 7) - 5y(2 - y)

2*3y - 2*7 - 5y*2 -5y*(-y)

6y - 14 - 10y + 5y²

5y² + 6y - 10y - 14

5y² -4y - 14

Answer:

$0.8\ m$

Step-by-step explanation:

In this problem we know that

The scale is equal to

$\frac{1}{250}\frac{m}{m}$

by proportion

Find what will be the height of the scale model

$\frac{1}{250}\frac{m}{m}=\frac{x}{212}\frac{m}{m}\\ \\x=212/250\\ \\x= 0.848\ m$

Round to the nearest tenth of a meter

$0.848\ m=0.8\ m$

Answer:

36.58% probability that one of the devices fail

Step-by-step explanation:

For each device, there are only two possible outcomes. Either it fails, or it does not fail. The probability of a device failling is independent of other devices. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

A total of 15 devices will be used.

This means that $n = 15$

Assume that each device has a probability of 0.05 of failure during the course of the monitoring period.

This means that $p = 0.05$

What is the probability that one of the devices fail?

This is $P(X = 1)$

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 1) = C_{15,1}.(0.05)^{1}.(0.95)^{14} = 0.3658$

36.58% probability that one of the devices fail
