On the left, first distribute the 8 to both terms to get 8*3a + 8*6 which =
24a+48.
Now you distribute on the right side to get 9*2a - 4*9 which = 18a - 36.
Now you set them both equal to get 24a+48 = 18a - 36
Get your a-terms together by subtracting 18a from both sides to get 6a+48=-36
Then subtract 48 from both sides and get 6a=-84. Divide by 6 and get
a = -14
Answer:
a) 0.9961
b) 0.9886
Step-by-step explanation:
We are given the following information:
We treat passenger not showing up as a success.
P(passenger not showing up) = 0.10
Then the number of passengers follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 125
a) probability that every passenger who shows up can take the flight
b) probability that the flight departs with empty seats
Answer:
there are 8 possible outcomes if that is what the question is.
otherwise the answer is 6 because 2 times 3 is 6
Answer:
x = 10
Step-by-step explanation:
You know z = x+4, so ...
3z -x/2 = 37 . . . . . . . . the given relation
3(x +4) -x/2 = 37 . . . . substituting for z
5/2x +12 = 37 . . . . . . .eliminate parentheses and simplify
5/2x = 25 . . . . . . . . . . subtract 12
x = 10 . . . . . . . . . . . . . multiply by 2/5
_____
<em>Check</em>
3z = 3·14 = 42
x/2 = 10/2 = 5
42 exceeds 5 by 37 . . . . true
