7. If U= {2, 4, 6, 8, 10, 12, 14, 16} and<br> A = {6, 10, 14}, what is A'?
Tresset [83]

The compliment of set A that is A' is equal to {2, 4, 8, 12, 16}.

We are given the universal set as:

U = {2, 4, 6, 8, 10, 12, 14, 16}

We are also given that set A is:

A = {6, 10, 14}

We need to find A'

For this, we will subtract set A from the universal set, U.

So, we get that:

A' = U - A

A' = {2, 4, 6, 8, 10, 12, 14, 16} - {6, 10, 14}

Solving the expression, we get that:

A' = {2, 4, 8, 12, 16}

Therefore, we get that, the compliment of set A that is A' is equal to {2, 4, 8, 12, 16}.

What is 1.45 as a mixed number in simplest form?
g100num [7]
Answer is (1 9/20) because 1 and 45/ 100 can be simplified by divided 45/100 by 5.  45 divided by 5 is 9 and 100 divided by 5 is 20.  A mixed number is a combination of a whole number and a fraction.  The whole number is 1 and the fraction is reduced to 9/20.

The department of public safety has an old memo stating that the number of accidents per week at a hazardous intersection varies
ELEN [110]

Answer:

P-value = 0.1515

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 2.2

Sample mean, \bar{x} = 2

Sample size, n = 52

Alpha, α = 0.05

Population standard deviation, σ = 1.4

First, we design the null and the alternate hypothesis

H_{0}: \mu =2.2\\H_A: \mu < 2.2

We use one-tailed(left) z test to perform this hypothesis.

Formula:

z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }

Putting all the values, we have

z_{stat} = \displaystyle\frac{2 - 2.2}{\frac{1.4}{\sqrt{52}} } = -1.03

Now, we calculate the p-value from the normal standard table.

P-value = 0.1515

Which of the following could not be the side lengths of a right triangle?
omeli [17]

Answer:

pls show what is the following

Step-by-step explanation:

how to find it by yourself:

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. ... In other words, as soon as you know that the sum of 2 sides is less than (or equal to) the measure of a third side, then you know that the sides do not make up a triangle.
