Given a spinner with 9 equal-area sections, a trial of 100 spins resulted in an experimental probability of 13% for the spinner
landing on 4. which of the following statements must be false?
a. the theoretical probability p(spinner < 4) = 100%
b. the theoretical probability p(spinner =4) = 11%
c. in a new trial of 100 spins, the experimental probability, p(spinner=4) may be different.
d. the experimental probability p(not spinner =4) = 87% for this trial.

The answer is spinner B. There are 8 sections on the spinner and 4 of them have letter A, so P(A)= 1/2.

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.
