Answer:
The correct answer is 2.2.
Step-by-step explanation:
The following represents the probability distribution for the daily demand of microcomputers at a local store:
Demand Probability
f(0)= .1
f(1)= .2
f(2)= .3
f(3)= .2
f(4)= .2.
Expectation of a discrete probability function f of the random variable x is given by ∑ x × f(x).
Thus the expected value of demand is given by
0.1 × 0 + 0.2 × 1 + 0.3 × 2 + 0.2 × 3 + 0.2 × 4 = 2.2.
The expected daily demand is 2.2.
Answer:
$1,272
Step-by-step explanation:
Just add 1,200 (how much she borrowed) and 6/100*1200 (6 percent of 1200) and you will get the answer of $1,272
Answer:
25.67 ft
Step-by-step explanation:
5.5 ft/6 = x/28 (5.5 ft is to 6 what x is to 28) (cross multiply)
(5.5 * 28) / 6 = 25.67 ft
