7n-2n+3p+2p
5n+5p (combine like terms)
the answer is 5n+5p
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.
Bro I’m rly sorry but I don’t know the answer to this
3ft/6yd= 7yd or in feet would be 21 feet or in inches would be 252 inches
f(x) = 2x - 7 This should be the answer!!
