Answer:

1. 4/11 2. 2/10 or 1/5

Step-by-step explanation:

The first thing you need to do is find the total number of marble and then break it into their probabilities. 4+2+5= 11

Red: 4/11, Yellow: 2/11 and Blue: 5/11

So for 1. you just need the probability of pulling a red marble with we already figured out, 4/11.

For the second part you're looking for the probability of pulling a yellow marble after a red was pulled and not replaced. When we take one out and don't replace it the only thing that changes is the total and the number for that color so, the probabilities change to: Red: 3/10, Yellow: 2/10 and Blue: 5/10.

So now you have the probability of pulling a yellow if a red was pulled first without being replaced.

How do you identify the opposite and the absolute value of a rational number
Sergeeva-Olga [200]

Rational numbers are the numbers that can be written as the fraction of two integers and absolute value is the distance a number is away from 0. If we look at a number line, the absolute value is the distance any number on the number line is away from 0. Distance is always positive, so our absolute value is always 0.

By applying the law of sines and some algebraic handling, the length of the side LJ is approximately equal to 3.517 units. (Right choice: D)

<h3>What is the missing side of the triangle according to the law of sines?</h3>

The law of sines presents a relationship between sides and <em>opposite</em> angles, which is described below:

9/sin 89° = LJ/sin 23°     (1)

LJ = 9 × sin 23°/sin 89°

LJ ≈ 3.517

By applying the law of sines and some algebraic handling, the length of the side LJ is approximately equal to 3.517 units. (Right choice: D)
