Answer:
And we can find this probability on this way:
And using the normal standard distribution table or excel and we got:
Step-by-step explanation:
Let X the random variable that represent the length of time student of a population, and for this case we know the distribution for X is given by:
Where 
and 
We are interested on this probability
We can solve the problem using the z score formula given by:
If we apply this formula to our probability we got this:
And we can find this probability on this way:
And using the normal standard distribution table or excel and we got:
Answer:
Step-by-step explanation:
Every time the line moves 5 units to the right, it moves up 4 units as well. Since the slope is the difference in y divided by the difference in x, the slope is 4/5. In addition, the y-intercept is -1. Therefore, the equation of this line is .
Answer:
angle x is an exterior angle of the triangle
If you would like to solve 2 1/2 divided by 1 5/8, you can calculate this using the following steps:
2 1/2 / 1 5/8 = 5/2 / 13/8 = 5/2 * 8/13 = 20/13 = 1 7/13
The correct result would be C. 1 and 7/13.
I'm pretty sure the answer will just be the 1.6 multiply by 512
