Answer:
88
Step-by-step explanation:
this question is a question that involves the use of the statistical principles of finding average
let the summation of the six scores of the biology test be represented as ∑x
∴ ∑x÷ 6=74
∑x=74 × 6
=444
444 is the summation of all the scores of all the six biology scores reuben had
the next test would be his 7th
let y represent the score for the 7th test
therefore, 
= 76
444 + y = (76 × 7)
444 + y = 532
y=88
Reuben needs to score 88 to raise his average to 76
Answer:
a) Arithmetic yₙ = 3*(n - 1) + 13
b) Geometric yₙ = 2*5⁽ⁿ⁻¹⁾
Step-by-step explanation:
Y= -1/3x + 4
This would make the equation in slope intercept form
Answer:
David scored : 24 < 6x = 0
Step-by-step explanation:
From the information given;
David scored ??? points less than six times the number of points Rich scored in a video game.
If ??? represents the number of points scored by Rich
The objective is to write an expression representing the number of points scored by David.
since the value of David points and Rich letter representing the number of points scored by RIch are not given, Let's based our calculation on assumptions, the main thing is to understand the the process in solving the question.
Assumption:
Let assume that,
David scored 24 points and x should be the number of points scored by Rich
Then; the linear equation representing David score is:
David scored : 24 < 6x = 0
