It’s a bro trust me on this one
Answer:
I hope I'm right but not totally sure (0,0) and (1,2)
Step-by-step explanation:
Graph the line using the slope and y-intercept, or two points.
Slope: 2
y-intercept: 0
x y
0 0 <<<<< That's supposed to be a chart
1 2
The answer should be 40 degrees. A triangle has 180 degrees total, so if you add the angles together then subtract from 180 it would be 40
Answer:
Step-by-step explanation:
Given
--- Mean
--- Variance
Calculate the standard deviation
Solving (a): P(X < 1.96)
First, we calculate the z score using:
This gives:
The probability is then solved using:
From the standard normal distribution table
So:
Solving (b): P(X > 1.64)
First, we calculate the z score using:
This gives:
The probability is then solved using:
From the standard normal distribution table
So:
Solving (c): P(0.5 < X < 0.5)
This can be split as:
In probability:
becomes
