Answer:

1. The correct answer is D) 1/36

Step-by-step explanation:

WE can tell this because the chance of rolling either is 1/6. To find the total probability we multiply those together.

1/6 * 1/6 = 1/36

Answer:

2x - 2y = 14

x - y = 2

1.) x = 2+ y

2.) 2(2+ y) - 2y = 14

3.) 4 + 4y - 2y = 14

4.) 4y - 2y = 14 - 4

5.) 2y = 10

6.) 2y/2 = 10/2

7.) y = 5

x - y = 2

8.) x - 5 = 2

9.) x = 2 + 5

10.) x = 7

Therefore, x = 7 and y = 5

Step-by-step explanation:

1. First make one of the variables in any equation the subject of the formula

2. Then substitute the variables equating to the subject of the formula

3. Group the like terms,then solve the equation.

4. Replace the value you will find in the first equation into the other equation.

5. Repeat with the same

A web site was hit 300 times over a period of 15 days Show that over some period of 3 consecutive days, it was hit at least 60 t
marshall27 [118]

Answer:

We will divide the 15 days in five periods of 3 consecutive days each.

Now to solve this we will use the pigeonhole principle.

This states that if (N+1) pigeons occupy N holes, then some hole must have at least 2 pigeons.

So, we have n=300 pigeons  and k=5 holes.

[\frac{n}{k} ]=[\frac{300}{5} ]

Hence, there is a period of 3 consecutive days in which the website was hit at least 60 times.
