In one town, 4% of 18-29 year olds own a house, as do 21% of 30-50 year olds and 55% of those over 50. according to a recent census taken in the town, 28.9% of adults in the town are 18-29 years old, 39.4% are 30-50 years old, and 31.7% are over 50. what is the probability of an adult owning a house in this town?
a) 0.027
b) 0.186
c) 0.269
d) 0.267

answear:

a

step-by-step explanation: a

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

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

2, 2, 2 or -4, 20, 29

step-by-step explanation:

there is two ways you can do it.
