Answer:

interquartile range = upper quartile - lower quartile

first, order the scores from least to greatest

4, 6, 8, 10, 12, 12, 18

thus, UQ = 6 and LQ = 12

IQR = UQ - LQ = 12 - 6 = 6

Can someone help me solve X

Salsk061 [2.6K]

Answer:

x = 30

Step-by-step explanation:

The coordinates A(2, 1), B(7, 1), C(2, 4) form what type of polygon?

Digiron [165]

Step-by-step explanation:

$Slope \: of \: AB = \frac{1 - 1}{7 - 2} = \frac{0}{5} = 0 \\ \\ Slope \: of \: BC = \frac{4 - 1}{2 - 7} = \frac{3}{ - 5} = - \frac{3}{ 5} \\ \\ \because \: Slope \: of \: AB \neq \: Slope \: of \: BC \\ \\ \therefore \: given \: points \: are \: non - collinear. \\$
