Answer:
1.5
Step-by-step explanation:
Applying,
Z = (x-μ)/σ................. Equation 1
Where Z = Z score for a height of 67 inches, x = height, μ = mean of the height, σ = standard deviation of the height.
From the question,
Given: x = 67 inches, μ = 64 inches, σ = 2 inches.
Substitute these values into equation 1
Z = (67-64)/2
Z = 3/2
Z = 1.5
Answer:
the force of the baseball is 300 N
So the area of a circle is pi x the radius squared.
To find the radius we need to half the diameter so 2.85mm
Next we need to square this so 2.85 x 2.85 = 8.1225mm
The area = pi x 8.1225
= 25.51758633mmsquared
= 25.5 mmsquared
Answer:
y=4
Step-by-step explanation:
first you that the number outside of the parenthesis and multiply it by the numbers inside 3x3y (ignore the y for right now) and 6x3 now we have 9y-18=18 now we move the 18 so the y is by itself now we have 9y=36 divide both by 9 and you get your answer y=4
