This is an algebraic expression, not an equation,. There is nothing to do to it. It is simplified.
Answer:
<h2>
9/35, 0.257 or 25.7%</h2>
Step-by-step explanation:
The basic and simple way to calculate the probability of an event happening is by using this equation:
<h2>Number of desired outcomes</h2><h2>------------------------------------------------- = Probability </h2><h2>Number of all possible outcomes</h2><h2 />
Our desired outcomes are picking either red or yellow candies. The number of desired outcomes in this case is the total number of red and yellow candies. 6 red + 3 yellow = 9
Number of desired outcomes = 9
Number of all possible outcomes in this case is the total number of candies in the bag. 10 green + 8 brown + 3 yellow + 8 blue + 6 red = 35
Number of all possible outcomes = 35
Use the formula and we get that the probabbility of drawing out a yellow or red candy is: 9/35, 0.257 or 25.7% (those are 3 different ways to write the probability)
Answer:
x = -5, 7
Step-by-step explanation:
Step 1: Write equation
x² - 2x - 35 = 0
Step 2: Solve for <em>x</em>
<u>Factor:</u> (x - 7)(x + 5) = 0
<u>Find roots:</u> x = -5, 7
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
(-5)² - 2(-5) - 35 = 0
25 + 10 - 35 = 0
35 - 35 = 0
0 = 0
7² - 2(7) - 35 = 0
49 - 14 - 35 = 0
35 - 35 = 0
0 = 0
