Answer:
x = 36
Step-by-step explanation:
EAB is a straight line so it equal 180
EAF + FAB = EAB
3x+2x = 180
Combine like terms
5x = 180
Divide each side by 5
5x/5 = 180/5
x = 36
It is the first choice
Pick any point on the purple heart and follow it to that exact point on the red heart
Hope that helps!
Answer:

And using the probability mass function we got:
Step-by-step explanation:
Let X the random variable of interest "number of times that 6 appears", on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want to find this probability:

And using the probability mass function we got:
Answer:
Step-by-step explanation:
#6
a n
---- = ---- Solve for a. Note that if we multiply both sides of this equation by
m p n
m, we get a = m * ----
p
m*n
and this simplifies to a = mn/p or a = ---------
#7 Solve mx = np for x. We want to isolate x on the left side. Dividing
both sides by m isolates x on the left and adds the divisor m on the right:
np
mx = np => x = ------
m
#8 Solve c - x = d + r for x We want -x alone on the left side. Accomplish this by subtracting c from both sides, obtaining:
-x = d + r - c. Now multiply both sides by -1, obtaining x = -d - r + c
