Answer:

Mai has less variability as compared to that of Priya

Step-by-step explanation:

IQR is the Inter quartile range and is the difference between upper and lower quartiles. It measures the variability as in terms it depicts the middle 50% of values when the values are arranged in ascending order

In case of Priya's median score was 118, and her IQR was 15. IQR = 15 means that there is a difference of 15 between the upper and lower quartiles

While in case of Mai, the IQR is 5 only.

Hence, Mai has less variability as compared to that of Priya

When a 40-foot pole casts a shadow of

Semenov [28]

Set up a ratio with height over shadow height:

40/30 = x/15

Cross multiply:

40 x 15 = 30x

600 = 30x

Divide both sides by 30:

X = 20

The tree is 20 feet tall.
