If the value of the z-score is 1. Then the probability that a cat will weigh less than 11 pounds will be 0.84134.
<h3>What is the z-score?</h3>
The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.
The z-score is given as
z = (x - μ) / σ
Where μ is the mean, σ is the standard deviation, and x is the sample.
The weight of a cat is normally distributed with a mean of 9 pounds and a standard deviation of 2 pounds.
Then the probability that a cat will weigh less than 11 pounds will be
The value of z-score will be
z = (11 – 9) / 2
z = 1
Then the probability will be
P(x < 11) = P(z < 1)
P(x < 11) = 0.84134
Thus, the probability that a cat will weigh less than 11 pounds will be 0.84134.

The period is found in one full cycle of the function. One "up-down-up", if you will. Our function starts below the x axis, so one full cycle goes from down to up to back down to back up. This up-down-up is complete at 3pi. So your answer is the third choice down.
SA=4pir^2
r=20m
SA=4pi20^2
SA=4pi400
SA=1600pi m^2
3/4 mate, since a fraction is almost always under 1, (except for improper ones), 3/4 should be 0.75 in decimal form.
