Abdul used a probability simulator to roll a 6-sided number cube and flip a coin 100 times. the results are shown in the tables below:
using abdul's simulation, what is the probability of rolling a '2' on the number cube and the coin landing on heads up?
a. 320/1
b. 450/1
c. 55/100
d. 65/100

P( rolling 2 and head) = .

Step-by-step explanation:

Given : Abdul used a probability simulator to roll a 6-sided number cube and flip a coin 100 times. The results are shown in the tables below.

To find :  what is the probability of rolling a '2' on the number cube and the coin landing on heads up.

Solution : we have given :

Number 2 on cube rolled = 10 times

Total number of times it rolled = 100.

Probability  = .

Probability of 2 rolled on cube = .

coin landing on heads up = 45.

Total number of times coin flip = 100.

Probability of landing on heads up = .

Then, P( rolling 2 and head) = P( rolling 2) * P( head).

Both are independent

P( rolling 2 and head) = *  .

P( rolling 2 and head) = .

Therefore, P( rolling 2 and head) = .

step-by-step explanation:

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.
