A quarterback completes 55% of his passes. We are interested in how many passes he athrows before he gets his first completion.

a) Determine that this particular setting is a GEOMETRIC SETTING.

b) What is the probability that the quarterback throws 3 incomplete passes before he
has a completion?

c) How many passes can the quarterback expect (the mean) to throw before he
completes his first pass?

d) What is the probability that the quarterback throws more than 5 passes before he
completes his first pass?

160

step-by-step explanation:

idk

i hope i

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
