Answer:

Step-by-step explanation:

U = {-3, -2, -1, 0, 1, 2, 3,4}

M= {-2, -1, 0 , 2}

M' = {-3, 1, 3, 4}

Complement of M refers to elements not in M and in U

Answer:

Therefore the required probability is 0.15.

Step-by-step explanation:

Poisson distribution:

The Poisson distribution is the number of an event is occur within a time period.

$P(X=x)=\frac{e^{-\mu}\mu^x}{x!}$

μ= The mean

x= event.

In Poisson distribution , the average rate event per time period is constant.

12% defective parts is produced by one of the machines of the time.

μ= (12%×7)= 0.84

x= the number of defective product =2

$P(X=2)=\frac{e^{-0.84}(0.84)^2}{2!}$

=0.15

Therefore the required probability is 0.15.

4x + 2 < −2 OR 4x + 2 > 26 <br><br><br> solve pl

inn [45]

Step-by-step explanation:

The easiest thing to do here is:

4x + 2 = -2 and 4x + 2 = 26

Just know whaever you get for x is greater or less than the actual answer.

4x + 2 = -2

- 2 - 2

4x = -4

$\frac{4x}{4} = \frac{-4}{4}$

x = -1 <--- Because -2 is supposed to be greater than x, x equals any number less than -1 but not -1.

4x + 2 = 26

- 2 - 2

4x = 24

$\frac{4x}{4} = \frac{24}{4}$

x = 6 <--- Because 26 is supposed to be less than x, x equals any numbey greater than 6 but not 6
