3-2y-8x is it's most simplified form I think.
The Z- score representing the 99th percentile is given by 2.33
Problems of commonly distributed samples can be solved using the z-score formula.
For a set with a standard deviation, the z-score scale X is provided by:
Z = ( x- mean )/ standard deviation
Z-score measures how many standard deviations are derived from the description. 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 scale is less than X, that is, the X percentage. Subtract 1 with p-value, we get the chance that the average value is greater than X.
To Find the z-result corresponding to P99, 99 percent of the normal distribution curve.
This is the Z value where X has a p-value of 0.99. This is between 2.32 and 2.33, so the answer is Z = 2.33

2 divided by 7 would give you 29%
Answer:
The circumference of circle is: 31.714 cm
Step-by-step explanation:
Let C be the circumference of the circle
And A be the area of circle
It is given that:
We have to find the radius first so that it can be used to find the circumference
The area of circle is given by the formula:
Putting the value of area
Taking square root on both sides
Now
Putting the value of radius
Hence,
The circumference of circle is: 31.714 cm
