A company finds that if it charges x dollars for a cell phone, it can expect to sell 1,000 – 2x phones. The company uses the function r defined by r(x) = x times (1,000 -2x) to model the expected revenue, in dollars, from selling cell phones at x dollars
each.

Use graphing technology to graph the function r. Sketch the graph here and
show the coordinates of the vertex and any intercepts.

step-by-step explanation:

answer: i literally just answered this question but they want me to do it again

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 %

it would rotate about 180 degrees.
