We can start by separating the x^3, and that means we have to multiply both sides by 4, resulting in x^3=27. Next, we can find the cube root of both sides ( as x is the cube root of x^3), getting x=3
Answer:
Step-by-step explanation:
The z-score corresponding to a given area of a distribution, is the number of standard deviations that the values in that area have/are from the mean.
In this case, we have a STANDARD normal distribution. In a standard normal distribution, the mean is 0 and the standard deviation is 1.
The Z-score corresponding to a given area, say the 30th percentile is
X = 0 + (-0.524)(1)
Hence, the X (number of values in the given percentile - in this case, 30th) is same as the z-table or z-calculator value for the 30th percentile in ANY normal distribution.
Answer:
Step-by-step explanation:
we know that
The surface area of the cone is equal to
where
r is the radius
l is the slant height
we have
----> the radius is half the diameter
substitute the values in the formula
Answer:
28.26 = 88.78140839
Step-by-step explanation:
C = 2 pi r
56.52=2 pi r
divide both sides by 2pie.
I'm confused??? Plz comment on this if you have more detail for the question.
