Answer:

1\dfrac{11}{16}

Step-by-step explanation:

\left(2 + \dfrac{2}{3}\right)^{2} =\left(\dfrac{2*3}{1*3}+\dfrac{2}{3} \right)^{2}\\\\\\=\left( \dfrac{6}{3}+\dfrac{2}{3} \right)^{2}\\\\\\=\left( \dfrac{8}{3} \right)^{2}\\\\=\dfrac{64}{9}

12 ÷ (2 + 2/3)² = 12 ÷ (64/9)

                      = 12 *\dfrac{9}{64}\\\\= 3 *\dfrac{9}{16}\\\\= \dfrac{27}{16}\\\\\\= 1\dfrac{11}{16}

How to calculate a probability
Lelu [443]
Probability is calculated by comparing the odds to a certain event occurring to the number of possible events.

P=\frac{possibility-of-an-event-occuring}{number-of-total-outcomes}

For example, take a six-sided dice number 1-6 on each side. The probability of rolling a 4 would be1 in 6 or 1/6. This is because of the six possible outcomes, rolling a 4 is only one of them.

P(4)=1/6

Now take the same dice. The probability of rolling an even number is 3/6. To see why, lets look at the total possible outcomes:

1
2
3
4
5
6

Of the 6 possibilities, 3 are even numbers.

P(even)=3/6 or 1/2

Simplify the expression. (3x/y)^-3
AysviL [449]

Answer:

y^3/(27 x^3)

Step-by-step explanation:

Simplify the following:

((3 x)/y)^(-3)

((3 x)/y)^(-3) = (y/(3 x))^3:

(y/(3 x))^3

Multiply each exponent in y/(3 x) by 3:

(y^3)/((3 x)^3)

Multiply each exponent in 3 x by 3:

y^3/(3^3 x^3)

3^3 = 3×3^2:

y^3/(3×3^2 x^3)

3^2 = 9:

y^3/(3×9 x^3)

3×9 = 27:

Answer:  y^3/(27 x^3)

Arrange these numbers from least to greatest:
zmey [24]
First let's put them all over 100.
-\frac{5}{8} would change to -\frac{62.5}{100}

-\frac{7}{9} to -\frac{77.7}{100}

-\frac{4}{5} to -\frac{80}{100}

-\frac{3}{7} to -\frac{42.8}{100}

Then if we put them from least to greatest it would be from highest to lowest (since they are negatives)

-\frac{4}{5}, -\frac{7}{9}, -\frac{5}{8}, -\frac{3}{7}

The answer would be B
