Mrs. Bowen asked students in her class the average number of minutes each person spent reading each night. The results are recorded below. Girls 43 27 20 20 28 32 26 35 22 30 30 42
Boys 35 20 21 10 15 12 15 45
What is the approximate difference between the standard deviation of boys and girls' reading times?
A 3
B. 8
C. 9
D.11​

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.

96 39 cause 135 -96=39 im smart (i used a calculater)

i recommend you do what your heart desires. if you're attracted to the same gender, then you're attracted to the same gender. you can't determine what your heart wants.
