The box-and-whisker plot shown represents the results of a final exam. Jimmy earned an 85 on the exam. Describe how his score co
mpares with those of his classmates.

(NOT A MULTIPLE CHOICE)
1 answer:
Answer:
a) False
b) False
c) False
d) True
Step-by-step explanation:
Since it is not a multiple choice question, I have answered it as a true/false question.
First, let's identify where Jimmy's score (an 85) lies in the box-and-whisker plot. It is on the upper quartile, which is also a 75% or ¾ mark compared to the scores his classmates obtained.
To the right, are those that score better than Jimmy (the scores increase to the right). Thus, to find the fraction of students that scored higher than him, we take 1 whole minus ¾, which would give us ¼.
Fraction of students that scored lower than Jimmy= ¾
(Since when we count the position of Jimmy's score, we count it with respect to the lowest score in the class.)

Answer:
A (first choice), F (last choice)
Step-by-step explanation:
Formulas for arithmetic sequences are generally written in one of two forms. The form you're given here is called an "explicit" formula. For some value of n, you can find the n-th term by evaluating the formula.
The form used in the first three answer choices is called a "recursive" formula. The value of the n-th term depends not on 'n', but on the previous term.
These two forms can be converted to each other like this:
explicit formula ⇔ recursive formula
The values of the first term (A₁), the common difference (d), and the term index number (n) are the same in both forms. Once you see this relationship, you should be able to find ...
- the first term
- the common difference
- the other formula for the same sequence
__
Here, the given function tells you ...
- A₁ = 5
- d = +4
This means the formulas that describe the same sequence are ...
_____
<em>Additional comment</em>
The commutative property of multiplication tells you that (n-1)(4) = 4(n-1). The order of the operands makes no difference. The given function has the first of these forms, the offered answer choices have the second of these forms.

C (see attached)
<h3>Step-by-step explanation:</h3>The linear portion of the graph is defined for x ≥ 1, with the point x=1 included. Only selections A and C do that.
The quadratic portion of the graph is defined for x < 1. Only selection C does that. (Selection A is doubly-defined for x > 1, so is not a function. It is undefined for x < 1.)
