An electronic dartboard has a diameter of 10 inches. the bull’s-eye has a radius of 1.5 inches. if a dart hits the board randomly, what is the chance it hits the bull’s-eye? check all that apply.
the dartboard area is roughly 78.54 square inches.
the dartboard area is roughly 314.16 square inches.
the bull’s-eye area is roughly 7.07 square inches.
the probability that a random dart strikes the bull’s-eye is roughly 0.09.
the probability that a random dart strikes the bull’s-eye is roughly 0.02.

Options

a); c); d)

Step-by-step explanation:

We calculate the area of the target using the formula of the area of a circle

Where r is the radius, which is equal to half the diameter.

Then the radius of the dartboard is 10 inches

Your area is:

We use the same formula to calculate the area of the porthole.

Where r = 1.5 in

The probability that a randomly launched dart hits the bull's eye is:

Finally the answer is:

- The dartboard area is roughly 78.54 square inches.

- The bull’s-eye area is roughly 7.07 square inches.

- The probability that a random dart strikes the bull’s-eye is roughly 0.09.

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
