is the mean.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation
, the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Upper 20% of weights:
The upper 20% of the weighs are weighs of at least X, which is found when Z has a p-value of 0.8. So X when Z = 0.84. Then
The upper 20% of the weighs are weights of at least X, which is , in which
is the standard deviation of all weights and
is the mean.
Answer:
Option A is correct answer.
Step-by-step explanation
If the given function is given as
f(x) =
then vertex is (h,k) and Its domain is set of all real numbers
and range is given to be y ≥k for a>0
So here in the question the equation is given as
on comparing the equation with given standard equation
we get a=3 which is greater than zero
h =1 and k=2
therefore vertex is (1,2) ,Domain is set of all real number
and range is y≥2
That is option A is correct!
