93 x 2 = 186
x = 186 - 112
x = 74
y = 2(80) - 74
y = 160 -74
y = 86
360 - 112 - 74 - 86 = 88
z = (88+86)/2
z = 87
2n<2
divide both sides by 2 to solve/isolate n
n<1

Step-by-step explanation:
Answer:
(a) 13 ounces.
(b) 1.732 ounces.
(c) 0.5
(d) 0.33
Step-by-step explanation:
Given : The amount of water dispensed follows a continuous uniform distribution from 10 ounces to 16 ounces. So, a=10 and b=16.
(a) The average amount of water dispensed by the machine = (a+b)/2 = (10+16)/2 = 13 ounces.
(b) The standard deviation of the amount of water dispensed =
= √36/12 =√3 = 1.732 ounces.
(c) P (13 or more ounces will be dispensed in a given glass) =
=
= 0.5
(d) P (between 12 and 14 ounces will be dispensed in a given glass) = ( here a=12 and b=14.)
=
= 0.33
