Triangles ABC and XYZ are similar, so the corresponding angle to A in XYZ triangle is angle X. We can actually find sin(X) very easily.
Because we know all sides and the right angle, we can use certain formula to find sin(X), like this:
sin(X) = opposite side / hypotenuse = 6/10 = 3/5
sin(X) = sin(A)
The correct answer is sin(A) = 3/5.
Answer:

And using the normal standard distribution table or excel we got:

The excel code would be:
"=NORM.DIST(1.38,0,1,TRUE) -=NORM.DIST(0,0,1,TRUE)"
Step-by-step explanation:
For this case we know that our random variable of interest is Z and the distribution is given by:

This distribution is an special case of the normal distribution.
And we want to find this probability:

And we can find this probability with this difference and using the concept of cumulative distribution function for a continuous distribution:

And using the normal standard distribution table or excel we got:

The excel code would be:
"=NORM.DIST(1.38,0,1,TRUE) -=NORM.DIST(0,0,1,TRUE)"
Answer:
-11/7
Step-by-step explanation:
Idk much. But for #1. You can actually overdose on both if you take a lot of it. So it’s wrong
