Which of the following statements shows the inverse property of addition?

Kaylis [27]

Answer:

$a+(-a)=0$

Step-by-step explanation:

Let $a\in \mathbb R$ , that is a be any real number.

The inverse property of addition says that, the sum of a number $a$ and its additive inverse $-a$ gives the identity element of addition which is zero.

That is :

$a+(-a)=0$

We can rewrite this as $-a+a=0$

From the above options, we have the correct answer to be the first choice

A process is normally distributed with a mean of 104 rotations per minute and a standard deviation of 8.2 rotations per minute.

Ilia_Sergeevich [38]

Answer:

Option B) In control as this one data point is not more than three standard deviations from the mean

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 104 rotations per minute

Standard Deviation, σ = 8.2 rotations per

We are given that the distribution of process is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

For x = 118

$z = \displaystyle\frac{118-104}{8.2} = 1.7073$

Thus, we could say that this data point lies within three standard deviations from the mean as:

$\mu - 3\sigma < x < \mu + 3\sigma\\104-3(8.2) < x < 104 + 3(8.2)\\79.4 < 118 < 128.6$

Thus, it could be said

Option B) In control as this one data point is not more than three standard deviations from the mean

wyatt earns 21$ for painting fences for 3 hours, if wyatt charges at the same rate how many hours will it take him to earn 28?

Dvinal [7]

Answer:

4 hours

Step-by-step explanation:

$\frac{28}{21} :\frac{y}{3}$

21 · y = 3 · 28

21y = 84

21y ÷ 21 = 84 ÷ 21

y = 4

How to solve k(a)=4a + 2: find k(a-3)

uysha [10]

If you meant to say k=(-3)

First thing you would do is plug in the (-3) to a

Your equations would look like this:

k(a) = 4(-3) + 2

You would multiply 4 × -3, giving you -12.

k(a) = 12 + 2

Then you would add 12 + 2, giving you 14.

k(a) = 14

k(a) would equal 14.
