Change the fraction 1/5 to a percent

Answers

A fraction is a short way to write a division problem.

Whenever you see a fraction, it means

(the top number) divided by (the bottom number).

When you pick up your pencil or your calculator and actually do the
division, the answer to the division is the decimal form of the fraction.

To change that fraction 1/5 to a decimal, divide 1 by 5 .

Then, to change the decimal to a percent, move the
decimal point 2 places that way ==>.

A bag contains 5 blue marbles, 6 red marbles, and 9 green marbles. Two marbles are drawn at random, one at a time. What is the probability of selecting a green marble and then, without replacing it, a red marble? A. 9/38 B. 9/190 C. 27/190 D. 3/38

Answers

Your answer would be C. 27/190.

This is because the probability of choosing green as the first marble would be 9/20, as there are 20 marbles in total and 9 of those are green.

The probability of choosing a red marble as the second marble would be 6/19, as no red marbles would have been lost if green was picked first, but there would be one less marble in total.

The 'and' rule for probability, the one that is used to determine the probability of P(A) and P(B), is to multiply, so we need to do 9/20 × 6/19 = 54/380 = 27/190.

State an equation, in vertex form for a quadratic relation whose vertex is not (0,0) but the vertex occurs the same location as x intercept

Answers

y= $(x-1)^(2)$

The vertex would be at (1,0). It also touches the x axis at (1,0).
