A) An elliptical-shaped whispering gallery has two chairs positioned at the foci of the ellipse, 6 m apart. The width of the room, measured along its minor axis, is 8 m. What equation represents the elliptical-floor if its center is at the origin and its major axis is horizontal?

B) The area of an ellipse is A = πab, where a is the semi-major axis, and b is the semi-minor axis. What is the area of the floor of the room? Round your answer to the nearest tenth.

area = m

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

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 %
