Hello!
First of all, for our first scenario, the variation or spread of a data set is represented by the range. You subtract the largest and smallest number in the data set to find how much is in between.
Next, the mode is the number of piece of data that shows up the most in the data set, or the most common piece. Therefore, the most popular color is the mode.
As you can see, number 3 clearly says mean in the problem. This is the average cost.
The median is the middle number. Basically, it splits the data in half. If half of the students are 15 or higher, the middle age is 15, therefore, the median is 15.
Therefore, our answers are below.
2. Mode
3. Mean
1. Range
4. Median

Hello!
Let's think about the denominators we have. A seventh goes on forever in no specified order. A fifth an a fourth have set decimal values, 0.2 and 0.25, so they are not repeating decimals. A ninth is 0.111111..., it repeats like this forever in a specified order. Therefore, 2/9, or 0.222222...., would be a repeating decimal.
Therefore, our answer is
.

Answer:15
Step-by-step explanation:
Solution
f(x) = -20
+14x + 12 and g(x) = 5x - 6.
(f/g)(x) = 
(f/g)(x) = 
<u>Step 1: </u>Now we have to factorize the numerator.
f(x) = -20x^2 + 14x + 12
Factor out -2, we get
= -2 (10x^2 - 7x - 6)
Now we can factorize 10x^2 - 7x - 6
f(x) = -2(2x + 1) (5x - 6)
<u>Step 2: </u>Plug in the factors
(f/g)(x) = 
<u>Step 3:</u> Cancel out the common factor (5x - 6) from the numerator and the denominator, we get
(f/g)(x) = -2(2x +1) = -4x -2
Since -4x -2 is linear expression, the domain is all the real numbers.
Therefore, the answer is –4x – 2; all real numbers
