Write this equation in standard form: (4, -1) m = 3

ziro4ka [17]

Standard form looks like this: Ax + By = C.

y - (-1) = 3(x - 4)

y + 1 = 3x - 12

y = 3x - 12 - 1

y = 3x + 13

Move 13 to left side and y to right side.

-13 = 3x - y

Done!

The sum of 4 consecutive integers is 182. W hat is the sum of the middle two numbers?

Kamila [148]

Answer:

91

Step-by-step explanation:

Let

x = first number

x+1 = second number

x+2 = third number

x+3 = fourth number

Total = 182

x + x + 1 + x + 2 + x + 3 = 182

4x + 6 = 182

Subtract 6 from both sides

4x + 6 - 6 = 182 - 6

4x = 176

Divide both sides by 4

x = 176 / 4

= 44

x = 44

x = 44

x+1 = 44 + 1 = 45

x+2 = 44 + 2 = 46

x+3 = 44 + 3 = 47

Sum of the two middle numbers = 45 + 46

= 91

Step-by-step explanation:

female : male

x : 1000

x : 4000

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
