<span>(360) = 10/25 = .4
z(380) = 30/25 = 1.2
P(350 < x < 380) = normalcdf(.4, 1.2)</span>
Answer:7.8102 is the distance between those two points
Step-by-step explanation:
Answer:
Red:green = 3:1, not 3:2
r:g = 3:1, so g:r = 1:3 = 2:6
r:t = 2:11 = 6:33
g:r:t = 2:6:33
now just read off the ratios.
r:t = 6:33 = 2/11
b:t = 1 - (g:t - r:t) = 25/33
b:g = 25/2
r:b = 6/25
Step-by-step explanation:
(I deserve to be the brainliest )
P= k/Q
16.4= k/123
k= 16.4 * 123
k= 2017.2
Therefore, P= 2017.2/Q
Hi, it will be really easy if you start out by plotting a tree diagram and tracing out the probabilities. Then you simply have to multiply the probabilities of placebo and improvement.
-----80% Medication -----76% improvement
-----24% no improvement
|
------20%Placebo --------62% no improvement
-----------38% improvement
Solving for P(placebo and improvement) = .20 x .38 = 0.076 = 7.6%
