Answer:
x=1 -3(1+4)=-15
Step-by-step explanation:
-3(x+4)=-15
---------------
-3 -3
x+4= 5
-4=-4
x=1
That should be right
9514 1404 393
Answer:
x = 65
Step-by-step explanation:
The sum of exterior angles of a polygon is 360°.
40 + x + 77 + 2x + 45 = 360
3x + 165 = 360 . . . . simplify
x + 55 = 120 . . . . . . divide by 3
x = 65 . . . . . . . . . . . subtract 55
Success = p
failure = (1-p)
is the correct first step.
To find the probability of at least one success, P(X>0), it is much easier to first calculate the probability of P(X=0)=NO success. Then the complement of
P(X=0)'=1-P(X=0) = P(>0) = probability of at least one success.
By the multiplication rule,
P(X=0)=(1-p)^9
or the binomial distribution
P(X=0)=C(9,0)(p^0)(1-p)^9=1*1*(1-p)^9=(1-p)^9
So the probability of at least one success = 1-P(X=0)
=1-(1-p)^9
