scores on a college entrance examination are normally distributed with a mean of 500 and a standard deviation of 100% of people who write this exam obtain scores between 425 and 575

Answers

We have

$\mu = 500$

$\sigma = 100$

425 corresponds to a z of

$z_1 = (425 - 500)/(100) = -\frac 3 4$

575 corresponds to

$z_2 = (575 - 500)/(100) = \frac 3 4$

So we want the area of the standard Gaussian between -3/4 and 3/4.

We look up z in the standard normal table, the one that starts with 0 at z=0 and increases. That's the integral from 0 to z of the standard Gaussian.

For z=0.75 we get p=0.2734. So the probability, which is the integral from -3/4 to 3/4, is double that, 0.5468.

You choose two different movies on a list at random. Out of 15 movies on the list, 9 are action movies. The first movie you choose is an action movie. What is the probability that the second movie is also an action movie? Write your answer as a fraction in simplest form.

Answers

Answer:

the probability is 8/15 depending on whether the problem counts the drawing one out of the bag as one gone. Leaving the first one drawn, the probability would be 3/5.

Step-by-step explanation:

number of action movies/total number of movies= 9/15=3/5

3/5 is the probability of drawing an action movie from the bag. However, since you just drew one out, the fraction changes to 8/15.

The length of 2 legs of a right triangle measure 5 meters snd 3 meters The length of the hypotenuse if √34 ( sqaure root of 34 ) meters. Approximate the length of the hypotenuse to the nearest thousandth of a meter.

Answers

Answer:5.830

Step-by-step explanation:

You just do √34 which is 5.830 because the legs are 5^2 which is 25 and 3^2 which is 9 and 25+9=34.
