Answer:
Recursive formulas give us two pieces of information:
The first term of the sequence
The pattern rule to get any term from the term that comes before it
So I think A.Pattern
Answer: B - The mean height of all the students of the college.
Explanation:
In statistics, the concept of parameter refers to the value that you want to know about a population to characterize it, for example, mean height, mean age, etc.
In this case, the value that you want to know about the population of the college is the mean height of its students, so the correct option is B.
The following concepts are used in statistics that can be applied to the given example:
- Population (all students of the university).
- Parameter (mean height of university students).
- Sample (the 25 randomly selected students).
- Elements (the heights of the selected students).
- Estimator (average height of randomly selected students).
First let's set up an equation: 35+0.05t.
35 is the phone rate per month plus the number of texts (t) times 0.05 (cost of 1 text)
Now we can find the amount of texts she sent each month.
March
35+0.05t=72.60
-35 -35
0.05t=37.60
------ -------
0.05 0.05
t=752
April
35+0.05t=65.85
-35 -35
0.05t=30.85
------ -------
0.05 0.05
t=617
She sent 752 texts in March and 617 texts in April.
1.64 euros times by 400 pounds is 656 euros
The fourth one because to know if it is a function or not it has to pass the vertical line test the first one when you draw a vertical line some of the lines repeats so does the second and third but the last one when you draw a vertical line it doesn't repeat s that means its a function
