Answer:
of what?
Step-by-step explanation:
Answer:
y=-2x+2
Step-by-step explanation:
This is a proportion problem that involves cross multiplication
3/5 = x/650
650 x 3 = 1950
1950/ 5 =390
Or you could have done 650 x .6 (which is the decimal form of 3/5) and got 390 as your answer
Answer:
1557/1892
Step-by-step explanation:
Your calculator can do this:

Answer:

And we can find this probability using the normal standard distribution and we got:

Step-by-step explanation:
For this case we have the foolowing parameters given:
represent the mean
represent the standard deviation
the sample size selected
And for this case since the sample size is large enough (n>30) we can apply the central limit theorem and the distribution for the sample mean would be given by:

And we want to find this probability:

We can use the z score formula given by:

And we can find this probability using the normal standard distribution and we got:
