Step-by-step explanation:
Before we can answer this question we need to understand what the information on the table shows.
This table shows how far away from the average rainfall each year was. When a number has a + in front of it, it was above average, which means there was more rain. If there is a - in front of it, it was below average, which means there was less rain.
From this, we can see that the largest negative numbers will be the least amount of rain and the largest positive numbers will be the greatest amount of rain.
This means that the order would be :
And in years this would be :
Answer:
D
Step-by-step explanation:
Basically, the space inside the circle is called the area. To find the area of a circle, the formula is pi times the radius squared.
In other words, you could write it like this:
Option D is this exact formula, therefore D is the correct answer.
The standard deviation of the data set is 19.3
<h3>How to find the standard deviation of the data set?</h3>
The dataset is given as:
82, 94, 105, 68, 57
Calculate the mean using
Mean = Sum/Count
So, we have
Mean = (82 + 94 + 105 + 68 + 57)/5
Evaluate
Mean = 81.2
The standard deviation is then calculated as:
So, we have:
SD = √[(82 - 81.2)^2 + (94 - 81.2)^2 + (105 - 81.2)^2 + (68 - 81.2)^2 + (57 - 81.2)^2)/5 - 1]
This gives:
SD = √[1490.8/4]
So, we have:
SD = 19.3
Hence, the standard deviation of the data set is 19.3

Answer:
C is the correct answer.
Step-by-step explanation:
Look at the X values for each coordinate pair. If an X value is represented twice with different Y values, it is not a function. If no X value is repeated, or it is repeated but has the same Y value, then it is a function. A has two values for x = 1, B has two values for x = -3, D has two values for x = 7, but C does not, so it is the correct answer.
