Answer:
P(odd number) = 0.5
Step-by-step explanation:
There are 90 members in the set (10, 11, 12, .. , 97, 98, 99)
When we have an even number of consecutive numbers, the number of even numbers equals the number of odd numbers. This means that half of the numbers in this set are even and half of them are odd.
So the probability of P(odd number) = 0.5
Answer: y=-5x(x- 2/5)^2 +4/5
Answer:
y = -3x - 4
Step-by-step explanation:
to get -3x, you calculate the slope, so you can pick a point and use rise over run, and to get -4, it starts -4 down on the x line
Ok, the explanation is horrible, but i promise the answer is correct
Distribute:
2x-6 = 8x-48
Solve for x:
2x-6 = 8x-48
-2x -2x
------------------
-6 = 6x - 48
+48 +48
----------------
42 = 6x
divide by 6 on both sides...
x=7
