The volume of a shampoo filled into a container is uniformly distributed between 370 and 385 milliliters. (a) what are the mean and standard deviation of the volume of shampoo? (b) what is the probability that the container is filled with less than the advertised target of 375 milliliters? (c) what is the volume of shampoo that is exceeded by 95% of the containers?

(a) mean = 377.5ml. standard deviation = 4.33

(b) 0.333

(c) 384.25 ml

Step-by-step explanation:

(a)The mean:

The standard deviation:

(b)

(c)P(x > m) = 0.95

So the volumn of shampoo should be 384.25ml to exceed 95% of containers.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
