Answer:
(A) ∫₁⁵[Xₙ + k] where n ranges from 1 to 5
(B) 73.6
Step-by-step explanation:
The question is clear enough. Kudos!
So there are many players but we're focusing on Ricky.
Ricky has already recorded his score for each of the 5 rounds in the tournament.
The number of strokes in Ricky's record are to be added to or subtracted from a given number 72
ROUND 1: [72 - 5] strokes = 67
ROUND 2: [72 + 6] strokes = 78
ROUND 3: [72 - 2] strokes = 70
ROUND 4: [72 + 4] strokes = 76
ROUND 5: [72 + 5] strokes = 77
(A) Write an expression to represent Ricky's total number of strokes for the five rounds.
Do not panic at this first exercise. You are to write an expression which when evaluated, will give the total number of strokes for all five rounds!
You are already given an abstract number '72' to work with in this question.
It is a fixed quantity which influences the value of strokes for each round.
We will represent this by an algebra, if we have to create the above required expression.
The expression will then be:
∫₁⁵[Xₙ + k] where n ranges from 1 to 5
You already know that the sigma sign '∫' represents summation and that's summation from the subscript '1' to the superscript '5'.
X₁ would be -5, X₂ would be +6, X₃ would be -2, X₄ would be +4, X₅ would be +5
K is the constant 72
(B) What was Ricky's average number of strokes per round?
Out of the 5 rounds, the average number of strokes per round would be
[67 + 78 + 70 + 76 +77] ÷ 5
= 368/5 = 73.6

What is simple interest?We know simple interest (SI) is given by SI = (p×r×t)/100, where
p = principle, r = rate in percentage, and t = time in years.
Given, On February 1, the balance in your account is $516.81 and the bank pays 6.25% interest.
Now, from February 1 to July 1 is 5 months or 5/12 years.
∴ SI earned is = (561.81×6.25×5/12)/100.
= $14.6
On July 1, you deposit $310.90 so the current balance is
$(516.81 + 14.6 + 310.90) = $842.31.
From july 1 to november 1 it is 4 months or 4/12 = 1/3 years.
∴ SI = (842.31×6.25×1/3)/100.
= $17.5.
The amount on November 1 is $(842.31 + 17.5) = $859.81

Find the series:0,2,6,12,20and.......?
Answer:
The series is represented by sum [tex]f(n) = 2 \cdot \Sigma\limits_{i=0}^{n} n[/tex], [tex]n \in\mathbb{N }[/tex]. The remaining element of the series is 30.
Step-by-step explanation:
This exercise consist in deriving the function which contains every element of the given series. The sum that contains all elements of the series { 0, 2, 6, 12, 20,...} is represented by the following formula:
[tex]f(n) = 2 \cdot \Sigma\limits_{i=0}^{n} n[/tex], [tex]n \in\mathbb{N }[/tex] (1)
Where [tex]n[/tex] is the cardinal associated with the element of the series.
Lastly, we proceed to evaluate the sum for the first five elements:
n = 0
[tex]f(0) = 0[/tex]
n = 1
[tex]f(1) = 0 +2[/tex]
[tex]f(1) = 2[/tex]
n = 2
[tex]f(2) = 0 + 2 + 4[/tex]
[tex]f(2) = 6[/tex]
n = 3
[tex]f(3) = 0 + 2 + 4 + 6[/tex]
[tex]f(3) = 12[/tex]
n = 4
[tex]f(4) = 0+2+4+6+8[/tex]
[tex]f(4) = 20[/tex]
The series is represented by sum [tex]f(n) = 2 \cdot \Sigma\limits_{i=0}^{n} n[/tex], [tex]n \in\mathbb{N }[/tex].
Lastly, the missing element is found by evaluating the function at [tex]n = 5[/tex], that is:
n = 5
[tex]f(5) = 0 + 2 + 4 + 6 + 8 + 10[/tex]
[tex]f(5) = 30[/tex]
The remaining element of the series is 30.
