Step-by-step explanation:

Given,

  • Total number of marbles = 6
  • Number of blue marbles = 2
  • Number of yellow marbles = 1
  • Number of red marbles = 3

We are asked to find the probability of choosing a blue marble if they are randomly chosen. Then,

Probabilty of a blue marble

= Number of blue marbles / Total number of marbles

= 2/6

= 1/3

               30- 2.5
               40- 12.5
               20- 7.5
3) Find the mean of those distances
               7.5+17.5+2.5+7.5+22.5+2.5+12.5+7.5/8=10

The Mean absolute deviation for this data set is 10.

What is 152,909 rounded to the nearest hundred thousands
lara31 [8.8K]
152,909 rounded to the nearest hundred thousands is 200,000.

Rules of rounding numbers
1) if the number being rounded off is followed by 0, 1, 2, 3, and 4, round the number down.
2) if the number being rounded off is followed by 5, 6, 7, 8, and 9, round the number down.

1 is the number on the hundred thousands place. It is followed by 5. We round 1 up to 2. Thus 2 is now in the hundred thousands place.

3√24= 3√2^2*6 = 3*2√6 = 6√6

2√384= 2√8^2*6 = 2*8√6 = 16√6

√96= √4^2*6 = 4√6

6√6 -16√6- 4√6 = -14√6

Final answer: -14√6

seropon [69]

Answer:

  Paolo made an error when he cross multiplied the proportion

Step-by-step explanation:

The proportion is ...

  \dfrac{3}{12}=\dfrac{x}{8}

"Cross multiply" means "multiply both sides of the equation by the product of the denominators."

  \dfrac{3}{12}(12)(8)=\dfrac{x}{8}(12)(8) \quad\text{cross multiply}\\\\(3)(8)=(x)(12) \quad\text{Paolo got something different}
