The weather service recorded some temperatures in Baltimore and Seattle throughout the month of October. Which statement is TRUE when comparing the interquartile range (IQR) of the cities?

A) The amount of spread in the middle-half of Baltimore's data is greater than Seattle's

Step-by-step explanation:

C)The temperatures in Baltimore and Seattle varied about the same for the month.

Step-by-step explanation:

The temperatures in Baltimore and Seattle varied about the same for the month..

Range = Max − Min

Baltimore: 35 − 23 = 12

Seattle: 28 − 16 = 12

The range for each city is 12: therefore, the temperature in each city varied about the same.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
