Arandom sample of people at a mall shows that 22 prefer to take a
family trip by car, 18 prefer to travel by plane, and 4 prefer to travel by
bus. is the sample method valid? if so, how many people out of 500
would you expect to say they prefer to travel by plane? (example 4)
also can you tell me how you got the answer .

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

step-by-step explanation:

a = (-2, 0)

b= (-4, 0)

c = (-5,2)

d = (-1,2)

his answer is incorrect. i just used it, and it said it was incorrect. the answer is 0.
