The standard deviation of the water depth is 3.53
<h3>Further explanation
</h3>
The standard deviation is a measure that is used to quantify the amount of variation or dispersion of a set of data values. The standard deviation is a measure of how spread out numbers are. Its symbol is σ (the greek letter sigma) The formula is the square root of the Variance. The variance is defined as the average of the squared differences from the mean.
There are steps to calculate the variance:
- Work out the Mean (the simple average of the numbers)
- Then for each number: subtract the Mean and square the result (the squared difference).
- Then work out the average of those squared differences.
A low standard deviation means that most of the numbers are close to the average. Whereas the high standard deviation means that the numbers are more spread out.

Ginny needs cups of sugar to make 36 cookies.
Step-by-step explanation:
Given,
Cups of sugar required to make 24 cookies =
Ratio of cups to cookies =
Let,
x be the cups of sugar required to make 36 cookies
Ratio of cups to cookies = x:36
Using proportion;
Ratio of cups to cookies :: Ratio of cups to cookies
Product of mean = Product of extreme
Dividing both sides by 24
Ginny needs cups of sugar to make 36 cookies.

Answer:
Easyy that is=√y2590
Step-by-step explanation:
that is for the equations
Step-by-step explanation:
Hey there!
According to the figure;
9v = 31° + 4v + 44° { The exterior angle is equal to the sum of opposite adjacent interior angles}
9v-4v = 44°+31°
5v = 75°
v = 75°/5
Therefore, v= 15°.
