Answer: 5/36

Step-by-step explanation: 2-6, 3-5, 4-4, 5-3, 6-2 are all the possible number permutaions that the sum is 8 on two fair dice. There are only 5 ways to make 8. the total number of possible number permutations you would get by squaring 6 to get 36. your answer would then be A. 5/36

13.50 for food
2.40 for drink

Since there is a voucher for 1/3 of food,

13.50 multiplied by 1/3 is 4.5 which is the discount

13.50-4.5=9

9 is the final cost for the food.

Add 9 to 2.40 for the drink which results in a total of 11.40

To find the amount charged for service you multiply 11.40 by .15

11.40 × .15 = 1.71

You add 1.71 to 11.40

The total is 13.11

Answer:Probability = 1/8.

Step-by-step explanation:

A number cube has six sides. Each side has a number from 1 to 6. This means that there are 3 even numbers (2, 4, and 6) and 3 odd numbers (1, 3, and 5). Therefore:

P(number cube lands on an even number after roll) = Number of even numbers/Number of total numbers. = 3/6 = 1/2.

Since the cube has to be rolled three times, the probability will be multiplied 3 times (assuming that each roll in independent of each other). Therefore:

P(number cube lands on an even number 3 times after roll) = 1/2 * 1/2 * 1/2 = 1/8.

Therefore, the answer is 1/8!!!

How do you write the equation of the horizontal line passing through (1,9)?
Leviafan [203]

he equation of any horizontal line is

y = .. a number

The x-value has no effect on the equation or on the line at all, as long as y-value stays the same.

In this case the line passes though the point (−8,9)

which tells us that the y-value we want is 9.

Therefore the equation is y=9
