22. Which is the interquartile range for the city that has the
greater variability
in temperature?

40

Step-by-step explanation:

Variability is a measures of the interquartile range of a given set of data. The greater the interquartile range, the more the variability.

The interquartile range (IQR) = Third quartile (Q3) - First Quartile (Q1)

IQR for City A = 70 - 40 = 30

IQR for City B = 80 - 40 = 40.

City B has a greater IQR value, therefore, it has the greater variability in temperature.

The interquartile range for the city with greater variability is 40.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
