A recently admitted class of graduate students at a large state university has a mean GRE verbal score of 650 with a standard de
hjlf

Answer:

The answer is below

Step-by-step explanation:

The z score is a score used to determine the number of standard deviations by which the raw score is above or below the mean, it is given by the equation:

z=\frac{x-\mu}{\sigma} \\\\\mu=mean, \sigma=standard\ deviation,x=raw\ score\\\\for\ a\ sample\ n:\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }

Given that μ = 650, σ = 50. To find the probability that 5 students who have a mean of 490, we use:

z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{490-650}{50/\sqrt{5} } =-7.16

From the normal distribution table, P(x < 490) = P(Z < -7.16) = 0.0001 = 0.01%

Since only a small percentage of people score about 490, hence the local newspaper editor should write a scathing editorial about favoritism

The vertex form of the function <br> y=x^2+8x+29
stira [4]

Answer:

y = (x+4)^2 +13

Step-by-step explanation:

y=x^2+8x+29

To complete the square take  the coefficient of the x term

8

Divide by 2

8/2 =4

Then square it

4^2 =16

y=x^2+8x+16+13

 = (x^2+8x+16)  +13

 = (x+4)^2 +13

Solve for the unknown.
kenny6666 [7]

Based on the balance sheet of Company MSK, we can find the unknown amount of Net Income (loss) to be $18,843.

<h3>What is the Net Income (loss)?</h3>

The Assets as at 2021 should be equal to the sum of liabilities and equity.

The Equity is:

= Issued stocks + Net income - Dividends

The missing figure is therefore:

35,564 = 15,721 + 1,400 + Net Income - 400

Net Income = 35,564 + 400 - 15,721 - 1,400

= $18,843
