Answer:
Step-by-step explanation:
z(lower) = (15-15)/4 = 0
z(upper) = (19-15)/4= 1
z at 0 = .5
z at 1 = 0.841344746
(look these up in a Z table)
probability "between" = 0.841344746 - .5 = 0.3841344746
Factor the numerator to get:
(-3z(z+5))/(z+5) now you notice that (x+5) cancel out leaving:
-3z
Volume formula is WxHxL so 3/2 times 4 times 1/2 is 3, the answer is 3 cm^3
If you look at the line it never stops. Y can be any number and X can be any number so X and y are elements of reels meaning your answer is a
Let me see if I am correct I will get back to u
