You have to integrate two equations, one for the case where the value in the absolute signs is negative and one for the case where the value is positive...
So you will integrate one on the interval 0 to 1 and the other on the interval from 1 to 3...
⌠-x+1 dx, x=[0,1] + ⌠x-1 dx, x=[1,3]
(-x^2/2+x)[0,1] + (x^2/2-x)[1,3]
(-0.5+1)+(4.5-3-0.5+1)
(0.5)+(2)
2.5 u^2
Answer:
Step-by-step explanation:
n/3 - 2 = 4 Add 2 to both sides
n/3 - 2 + 2 = 4+2 Combine
n/3 = 6 Multiply both sides by 3
3*n/3 = 6 * 3
n = 18
P = probability it rains tomorrow
q = probability it does not rain tomorrow
Since it either rains or it doesn't rain, this means p+q = 1
Think of 1 as 100% indicating total certainty
Solve for q to get
q = 1-p
by subtracting p from both sides
We're given p = 0.30 which is the probability of it raining, so,
q = 1-p
q = 1-0.30
q = 0.70
Answer: 0.70
