If you trace your finger along the line, the points at where your finger increase and decrease along the y axis are these intervals. Interval notation is useful because it states starting points and end points. The first number is the min, and the second is the max number.
Decreasing:
[-8,-5)
[4,8)
Increasing:
(-5,0]
Answer:

Step-by-step explanation:
you add, then add again, and then subtract, then add again, and then subtract again.
Answer:
the probability that the project will be completed in 95 days or less, P(x ≤ 95) = 0.023
Step-by-step explanation:
This is a normal probability distribution question.
We'll need to standardize the 95 days to solve this.
The standardized score is the value minus the mean then divided by the standard deviation.
z = (x - xbar)/σ
x = 95 days
xbar = mean = 105 days
σ = standard deviation = √(variance) = √25 = 5
z = (95 - 105)/5 = - 2
To determine the probability that the project will be completed in 95 days or less, P(x ≤ 95) = P(z ≤ (-2))
We'll use data from the normal probability table for these probabilities
P(x ≤ 95) = P(z ≤ (-2)) = 0.02275 = 0.023
Answer:
y - 5 = 3(x - 2)
y - 5 = 3x - 6
y = 3x - 1
