Identify the lower quartile (Q1), the median (Q2), and the upper quartile (Q3) for this data set. {1, 2, 4, 5, 7, 7, 8, 9, 9, 10}

a Q1 = 1, Q2 = 7, Q3 = 10
b Q1 = 4, Q2 = 7, Q3 = 9
c Q1 = 2, Q2 = 8, Q3 = 8
d Q1 = 4.5, Q2 = 7.5, Q3 = 9.5

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
