Answer: 22 degrees.

Step-by-step explanation:

A standard deviation is used to show what values are statistically close to the mean value of a set of values.

In this case, the mean is 24 degrees. A standard deviation of 4 degrees means that any value less than or greater than 24 by 4 degrees would be considered within one standard deviation.

This means that 21 degrees would be within one standard deviation, as would 26.

Looking at our choices, we can notice that 18 and 19 are both less than 20, the minimum value needed for one standard deviation. 30 meanwhile is above the maximum value (28) needed for one standard deviation.

The correct answer here is 22 degrees.

Each output value is equal to the square of the input value minus<br> five
Ivenika [448]

i think that A pair of an input value and its corresponding output value is called an ordered pair and can be written as (a, b). In an ordered pair the first number, the input a, corresponds to the horizontal axis and the second number, the output b, corresponds to the vertical axis.

We can thus write our values as ordered pairs

(0, 0) - This ordered pair is also referred to as the origin

(1, 2.5)

(2, 5)

(3, 7.5)

These ordered pairs can then be plotted into a graph.
