THE RIGHT ANSWER IS D; Both distributions are skewed left, so the interquartile range is the best measure to compare variability.

100% the correct answer I just took the test, went back and copied ^ this over from my test. It was correct I promise!! Have a good day and get these credits finished before senior year like me!! :D

Plotting the data (attached photo) roughly shows that the data is skewed to the left. In other words, data is skewed negatively and that the long tail will be on the negative side of the peak.

In such a scenario, interquartile range is normally the best measure to compare variations of data.

Therefore, the last option is the best for the data provided.

Answer:

The distance between the art gallery and the office supply store is 42 miles

Step-by-step explanation:

Notice that the segment that joins the office store with the art gallery, has a length that equal the distance between the art gallery and the bank, plus the distance between the bank and the office supply store. That is;

32.1 mi + 9.9 mi = 42 mi

Amanda leaned a 15-foot ladder against the top of her house so she could get on the roof, which is 12 feet from the ground.

valentinak56 [21]

If you're trying to find the missing side of the "triangle" (the distance from the house to where the ladder touches the ground), you would use the pythagorean theorem, a²+b²=c². (c is always hypotenuse)

a²+b²=c²

12²+b²=15²

144+b²=225

b²=81

√b²=√81

b=9

Which of the following expressions represents the distance between-1/4 and 3/4

Shalnov [3]

Answer:

|-1/4 - 3/4|

Step-by-step explanation:

To get the distance, take the absolute value of the second point minus the first point

| 3/4 - - 1/4|

|3/4 + 1/4|

We can also take the absolute value of the first point minus the second point

|-1/4 - 3/4|
