The probability that John will drive to school is 0.36 , the probability that he will ride with friends is 0.11 , and the probability that his parents will take him is 0.53 . He is not allowed to have passengers in the car when he is driving. What is the probability that John will have company on the way to school?

0.64 = 64% probability that John will have company on the way to school

Step-by-step explanation:

John will have company when:

He rides with his friends(0.11 probability).

His parents take him(0.53 probability).

What is the probability that John will have company on the way to school?

0.11 + 0.53 = 0.64

0.64 = 64% probability that John will have company on the way to school

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
