The manager of a hardware store sells batteries for $5 a package. She wants to see how much money she will earn if she increases the price
in 10¢ increments. A model of the price change is the revenue
function R(x) = – x2 + 10x + 3000, where x is the number of
10¢ increments and R(x) is in dollars. Explain how to determine the
maximum revenue.

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.

a box 3 3/4 feet long or 4+ feet.

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
