The Z-score (z) is calculated according to the formula: z = (x - μ) / σ
Where: x is the raw score value, μ is the mean of the population, σ is the standard deviation of the population.
x = 80, μ = 5, σ = 4
z = (80 - 5) / 4
z = 75 / 4 = 18.7500
Z-score is 18.7500
Answer:
The range is y > 0
Step-by-step explanation:
3^x is always greater than 0 and cannot be negative unless x is not real
I'm assuming you want to find the wind speed.
the ground speed against the wind is 410.
2460 / 6 = 410
the ground speed against the wind is 492.
2460 / 5 = 592
the difference is 82 mph, but you need to divide by 2 because speed is being added in one direction and subtracted in the other.
82 / 2 = 41
your final answer is 41 mph.
Answer:
The height of ball when it is at maximum height is 12 unit
Step-by-step explanation:
Given as :
A ball is thrown by child to height y
And y as a function x is y = 
So, for maximum value of height ,
= 0
Or , 
= 0
Or, 
= 0
Or, 
= 2
or, x = 12
Hence The height of ball when it is at maximum height is 12 unit Answer
Step-by-step explanation:
write the one digit in the square of each of the following numbers
a.13
