Answer:

Range: 41

(IQR) Interquartile Range: 27.5

Step-by-step explanation:

Interquartile Range: Upper Quartile - Lower Quartile = answer

Range: Highest value - Lowest value = answer

Arrange the list of numbers from least to greatest.

9, 12, 14, 15, 17, 36, 45, 50

Range: 50 - 9 = 41

Median: 16

Lower Quartile: 13

Upper Quartile: 40.5

Interquartile Range: 40.5 - 13 = 27.5

Select the correct similarity statement.
Nostrana [21]

Answer:

∆STR ~ ∆RTQ

Step-by-step explanation:

For two fugures to be considered similar, it means the corresponding sides are proportional, and as such, the ratio of their corresponding sides are equal.

However, the corresponding angles of two similar figures are the same and equal.

Taking a look at the figure of the triangle given, ∆STR is a right angle triangle, and it is similar to ∆RTQ as the angle formed at <T in ∆RTQ = 90°.

<T in ∆STR = <T in ∆RTQ.

Therefore, the correct similarity statement is ∆STR ~ ∆RTQ.

The last option is correct.
