Find an explicit formula for f(n). ​
soldi70 [24.7K]

Answer:

f(n) = 2n - 2

Step-by-step explanation:

Given the recursive formula

f(n) = f(n - 1) + 2 with f(1) = 0, then

f(2) = f(1) + 2 = 0 + 2 = 2

f(3) = f(2) + 2 = 2 + 2 = 4

f(4) = f(3) + 2 = 4 + 2 = 6

The terms of the sequence are 0, 2, 4, 6, ....

These are the first 4 terms of an arithmetic sequence with explicit formula

f(n) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here d = 2 - 0 = 4 - 2 = 6 - 4 = 2 and a₁ = 0, thus

f(n) = 0 + 2(n - 1), that is

f(n) = 2n - 2 ← explicit formula

Walter’s history test scores and Janine’s history test scores are shown on the dot plots below.
gogolik [260]

Using the dot plot and statistical concepts, it is found that the correct option is:

  • Their means will be most affected because this value will be an outlier.

<h3>What is a dot plot?</h3>
  • The dot plot shows the <u>number of times each measure appears in the data-set.</u>

In this problem, for both Walter and Janine, the dot plots are cluster between 80 and 90, which means that their grades are in this range.

  • Hence, for both, a grade of 65 would be an outlier, and the measure that is most affected by outliers is the mean.

Hence, the correct option is:

  • Their means will be most affected because this value will be an outlier.
