F(x) = 3x-1
g(x) = x+2
Find (f-g)(x), this means we need to subtract g from x.
(3x-1) - (x+2)
Subtract the like terms:
3x -x = 2x
-1 -2 = -3
Combine them to get 2x-3
The answer is A.
Answer:
k-n+1
Step-by-step explanation:
How many numbers are written from n to k
Lets look at a smaller example with real number
Lets go from 3 to 8
3 4 5 6 7 8
There are 6 numbers
We take 8 -3 = 5, but we include the number 3 so we add it back in +1
5+1 =6
Lets look at a larger example
2 to 11
2,3,4,5,6,7,8,9,10,11
There are 10 numbers
11-2 =9 but we have to add back in the first number
9+1 =10
Now we are going from n to k
k-n = k-n, but we have to add back in the first number
k-n+1
Answer:
<u>Descriptive</u> statistics consists of organizing and summarizing information collected, while <u>inferential</u> statistics use methods that generalize results obtained from a sample to the population and measure the reliability of the results.
Step-by-step explanation:
By definition, descriptive statistics summarize a given data set using measures of central tendency and measures of variability.
Measures of central tendency include:
Measures of variability include:
- standard deviation.
- variance.
- the minimum and maximum variables.
By definition, inferential statistics are used to make generalizations about a population from data samples.
For example, you might ask a sample of 100 people if they like shopping. You could make a bar chart of yes or no answers (descriptive statistics) or you could use your research and then, reason which is the percentage of the population that likes shopping (inferential statistics).
