A number is selected from the set (1, 2, 3, 5, 15, 21, 29, 38, 500). If equal elemental probabilities are assigned, what is

Katen [24]

Answer:

$\frac{7}{9}$ OR 77.78%

Step-by-step explanation:

So, we first need to find out how many numbers fit the "less than 29 or odd" group.

This would be: 1, 2, 3, 5, 15, 21, and 29, which is a total of 7 numbers.

Next, we figure out the total amount of numbers in the population.

This would be: 1, 2, 3, 5, 15, 21, 29, 38, and 500, which is a total of 9 numbers.

Finally, we put the first number (7) over the total (9) = $\frac{7}{9}$

$\frac{7}{9}$ is now able to be written in a percentage, if you need.

The probability is $\frac{7}{9}$ OR 77.78%

What is the expression in radical form?

RoseWind [281]

Answer:

The answer is;

4^3/10 • x^9/10 •y^3/5

Step-by-step explanation:

We want to express the expression in the bracket in radical form;

(4x^3y^2)^3/10

What we shall do here is to multiply all the powers of the terms in the bracket by 3/10

So we shall have;

4^3/10 • x^(3*3/10) * y^(2*3/10)

= 4^3/10 • x^9/10 • y^3/5
