Answer:
0.3257
Step-by-step explanation:
Given an approximately normal distribution:
Z = (x - mean) / standard deviation
Mean = 496 ; Standard deviation = 110
For :
P(x > 545.7)
We obtain the standardized, Z score
Z = (545.7 - 496) / 110
Z = 49.7 / 110
Z = 0.4518
Hence, using the Z distribution table :
P(Z > 0.4518) = 1 - P(Z < 0.4518)
P(Z > 0.4518) = 1 - 0.67429
P(Z > 0.4518) = 0.32571
Answer:
D)
Step-by-step explanation:
0.04, 0.40, 4.04, 40.04
Ok first I call the slope gradient
The gradient is
rise / run
This means
The change in the y value over two points/
The change in the x value over two points
eg
(3,5) (6,7)
Let’s say I took those two points out of my graph
Then the gradient is
7-5 / 6-3
Rise/run
Which is
2/3
Now let’s the the same with yours
Choose two points on your graph and do the same
