1. IQR = Q3 - Q1 = 35 - 20 = 15

A. 15

3. The ages include 20 and 25 so A and C are out, and the ages are between the two ages

B. a >= 20 and a <= 25

4. With the addition of 30, there are now 14 dots. Therefore, the median will be the mean of the 7th and 8th dots from least to greatest on the number line. In this case, it would still be 22.

Answer:

Step-by-step explanation:

y - y₁ = m ( x - x₁)

y - 5 = - 3 (x - 12)

y - 5 = -3x + 36

Answer:

$\huge\boxed{A=4d^2+4h}$

Step-by-step explanation:

$\dfrac{1}{4}A-h=d^2\qquad\text{add}\ h\ \text{to both sides}\\\\\dfrac{1}{4}A-h+h=d^2+h\\\\\dfrac{1}{4}A=d^2+h\qquad\text{multiply both sides by 4}\\\\4\!\!\!\!\diagup^1\cdot\dfrac{1}{4\!\!\!\!\diagup_1}A=4d^2+4h\\\\A=4d^2+4h$
