Two teams, A and B, are about to play a game. Previous records show that A has an 80% chance of winning, while B has a 20% of winning. Spectators can either choose to buy regular tickets or special tickets. A spectator with a special ticket will receive a refund of $2 if team A wins and a refund of $5 if team B wins. How much extra, minimally, should the special ticket cost to cover the expected value of the refunds offered?

A. $16.00

B. $2.60

C. $26.00

D. $3.00

E. $10

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
