5. no because each spinner is not the same size. it's not divided equally. 6. yes because a cube has 6 faces, so 1 on each is even. 7a. 12% 8. the bag with 25 tiles has a 40% chance of blue tiles and the bag with 250 tiles has a 30% chance, so the chances of picking a blue tile from the 250 tile bag is lower

Answer:

5 and 6 look down.

7. 12%

8. 75/250 30%

Step-by-step explanation:

5. The spinner shown is not a fair spinner because sections 1 and 5 are bigger than the rest of the sections.

6. The cube is fair because you have a 1 in 6 chance of getting a number. There is not a greater chance to roll a 1 than a 4.

7. There are 3 marbles that are white out of 25. This means that the probability of getting a white marble is a 3/25 chance.

There is a 12 percent chance that you will pick a marble

8. In this problem you are doing the same thing as 7. 10/25 is 40% chance and 75/250 is 30% chance.

A standard step height is 8". If there are 6 steps, how high is the top landing in<br> feet? *
DENIUS [597]

Answer:

4 feet

Step-by-step explanation:

If the standard step height is 8", this means that every step in a staircase will have a height of 8". If there are a total of 6 steps in the staircase we can simply multiply the number of steps by the height of each individual step to get the total height of the top landing. Like so...

6 * 8 = 48"

Finally, we can see that the top landing for the stairs is 48". We can turn this into feet by dividing by 12 since there are 12" in a foot

48 / 12 = 4 feet

Therefore, the top landing will have 4 feet ( or 48 inches)

F = mn/d

multiply both sides with d

d/F = mn/F

So..

d = mn/F

Which expression is equivalent to (x^27y)^1/3?
Kazeer [188]

Answer:

It's the second one

Step-by-step explanation:

If you use exponent rules (a*b)^n=a^n*b^n. Raise each term separately to 1/3 (by multiplying by 1/3) and then you get x^9 (y^1/3)
