The formula to calculate the z-score of a certain value is:
z = (x - (mean))/(standard deviation)
In this example, the x-value is 450, the S.D. is 100, and the mean is 500.
So, substitute these values into the formula.
z = (450-(500))/100
z=-50/100
z=-0.5
Therefore, the z-score is -0.5.
Ur answer would be B.. Hope it helps let me know if its right or not!
Answer:
-75 meters
Step-by-step explanation:
First, subtract 15 from 50, since it is going up:
50 - 15
= 35
Then, add 40, since it is going back down:
35 + 40
= 75
So, the new position is -75 meters relative to sea level
Answer:
8/3
Step-by-step explanation:
Subtract 6n and subtract 1
3n = 8
Divide by 3
n = 8/3
The answer will be 0.2 and 0.03 that will be the prduct of 0.4 and 0.09 I hope that helped you.
