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
y is -2/53
Step-by-step explanation:
- Step 1: Given equation is y = 2/5x-3 and x = -10. Substitute value of x to find the solution.
⇒ y = 2/(5 × -10 - 3) = 2/-53 = -2/53
Start at +1 on the x axis and then use 3/1 for rise over run. So you will start at +1 and then from that point rise 3 run 1
The answer would be -x^2 + 6x - 3/2
The answer is b because 2S + L is equal to L + 2S.
