Answer:

Building and solving an equation, it is found that the coordinates are: (9,0).

We are given two points: A(-9,3) and B(21, -2).

We also want point C(x,y).

C is 3/5 of the way from A to B, thus:

This is used to find both the x-coordinate and the y-coordinate of C.

First, the x-coordinate, considering .

Then we get 9,0

The caffeine content of a cup of home-brewed coffee is a normally distributed random variable with a mean of 115 mg and a standa
sdas [7]

Answer:

115 mg

Step-by-step explanation:

The 50th percentile has a corresponding z-score of z = 0. The z-score, for any given value of caffeine, X, is given by:

z = \frac{X-mean}{SD}

Therefore, if z=0, then X must be equal to the mean value of the normal distribution, which is 115 mg. Thus, the 50th percentile value of caffeine content is 115 mg.
