The finishing times, in minutes, for running marathons have an unknown distribution with mean 297 and standard deviation 32 minu
dangina [55]

Answer:

The mean for the sample mean distribution is 297 minutes.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, a large sample size can be approximated to a normal distribution with mean \mu and standard deviation \frac{\sigma}{\sqrt{n}}.

Using the Central Limit Theorem for Means, what is the mean for the sample mean distribution?

The mean is the same as the population mean, that is, 297 minutes.

Derek walks along a road which can be modeled by the equation y =2x, where (0,0) represents his starting point. When he reaches
Lady_Fox [76]

Answer:

(35,0)

Step-by-step explanation:

Consider the diagram below, the starting point is given as A and the finish point given as C.

Using similar right-angle triangle, we have that:

\frac{|AM|}{|BM|}= \frac{|BM|}{|MC|}\\\frac{7}{14}= \frac{14}{x}\\7x=14 X 14\\x=196/7=28

Therefore to find the point where Derek stops at C, we first determine the distance |AC|

|AC|=7+28=35

The Coordinates at C where Derek stops is (35,0)
