The z-score is -0.428
<h3>What is a z-score?</h3>
A z-score, also known as a standard score, provides information on how far a data point is from the mean. Technically speaking, however, it's a measurement of how many standard deviations a raw score is from or above the population mean.
You can plot a z-score on a normal distribution curve.
You must be aware of the mean and population standard deviation to use a z-score.
Z-scores allow results to be compared to a "normal" population.
According to the question,
x=500
μ=533
σ=77
z-score=(x-μ)/σ
On substituting the values,
z-score=(500-533)/77
= -0.428

prove me wrong
Answer:
The area of the whole cirlce should be: S = πr² = 3.14 . 5² = 78.5 (yd²)
The area of the triangle inside the cirlce should be: S = hb/2 = 7(4 . 2)/2 = 28 (yd²)
Now to find the area of the shaded region we just need to subtract the area of the cirle to the area of the triangle: 78.5 - 28 = 50.5 (yd²)
You would do 92 minus 20 and get 72 and divide that by 9 for 9 hours so the answer is 8
