Formula for Pythagorean theorem is a squared plus b squared equals c squared. The longest side is c and the rest is a and bb. Since we already have c we use formula a squared equals c squared minus b squared. AsquaredsquaredsquaredsquaredAsquaredsquaredsquaredsquared my thing is broken so I can't continuecontinue. Hope this helpshelps though

You are interested in estimating the mean of a population. You plan to take a random sample from the population and use the samp

Alja [10]

Answer: The standard deviation of the sampling distribution of M is equal to the standard deviation of the population divided by the square root of the sample size.

You can assume that the sampling distribution of M is normally distributed for any sample size.

Step-by-step explanation:

According to the central limit theorem , if we have a population with mean $(\mu)$ and standard deviation $\sigma$ , then if we take a sufficiently large random samples from the population with replacement , the distribution of the sample means will be approximately normally distributed.
When population is normally distributed , then the mean of the sampling distribution = Population mean $(\mu)$
Standard deviation of the sampling distribution = $\dfrac{\sigma}{\sqrt{n}}$ , where $\sigma$ = standard deviation of the population , n= sample size.

So, the correct statements are:

You can assume that the sampling distribution of M is normally distributed for any sample size.
The standard deviation of the sampling distribution of M is equal to the standard deviation of the population divided by the square root of the sample size.

What is the ratio of rise to run between the points (3,4) and (-2,0)?

Mila [183]

Ratio of rise can also mean the slope so let's find the slope given the two points.

slope formula;
m = y2 - y1/ x2 - x1 (3, 4), (-2, 0) (x1, y1), (x2, y2)

m = 0 - 4/ -2 - 3
m = -4/-5
m = 4/5

so your answer is B.

hope this helps, God bless!
