Answer:
The z-score is 2.5106 which is an unusual value of z-score as it is greater than 2.00
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 161 pounds
Standard Deviation, σ = 23.5 pounds
x = 220 pounds
Formula:
Putting values, we get,
Thus, the z-score is 2.5106 which is an unusual value of z-score as it is greater than 2.00
Answer:
1/4πs^3
Step-by-step explanation:
The volume of a cylinder = πr^2h.
Here its height h = s and its radius r = 1/2 diameter = s/2.
So it's volume is π(s/2)^2s
= 1/4πs^3.
Answer: If the plane is perpendicular to the line, the normal vector of the plane is equal to the direction vector of the line
Step-by-step explanation:
Answer:
1 and -2
Step-by-step explanation:
-2x^2=2x-4 so 2x^2 + 2x -4 = 0
2(x^2+x-2)=0
x^2+x-2 = (x-1)(x+2)
x=1 x=-2
