Z = 0.80 just to the right of z= 0. Note that the area to the right of z=0 is 0.5. The area to the right of 0.80 is smaller.
One way of answering this question is to use a calculator:
normalcdf(0.80, 1000) = 0.212 (answer)
Answer:
The answer to the question is 15.25
Answer:
Well this is kinda confusing
Step-by-step explanation:
im explaining the best way I can.
for exp 10 to the power of four = 40
but 10 to the power of 0 is 10
This is because your not multiplying by anything. it's just a normal number. I'm sorry I don't know what I got at here but I hope it helps a little. I'm honestly really sorry.
Answer:
See below.
Step-by-step explanation:
Plot some points:
y = 4^x
When x = 0 y = 4^0 = 1 so the graph passes through (0,1).
x = 1, y = 4^1 = 4 so it passes through (1,4).
You can plot a few more points for x = 2 and x = 3 . You'll see that the graph rises at a fast rate for positive values of x.
When x = -1 , y = 4^-1 = 1/4
x = -2 , y = 1/16
x = -3, y = 1/64
Thus, for negative values of x, the values of y rise slowly from close to y = 0 to meet the y axis at y = 1. When x approaches negative infinity y is very close to 0 but never is 0.
