(PLEASE ANSWER!!) a college student completed some courses worth 4 credits and some courses worth 3 credits. the student earned
Ierofanga [76]

The college student took 13 courses of 3 credit hours.

Step-by-step explanation:

Given,

Total credits = 59

Total courses = 18

Let,

Number of 3 credit hour courses = x

Number of 4 credit hour courses = y

According to given statement;

x+y=18     Eqn 1

3x+4y=59   Eqn 2

We will eliminate y to find the number of 3 credit hour courses, therefore,

Multiplying Eqn 1 by 4

4(x+y=18)\\4x+4y=72\ \ \ Eqn\ 3

Subtracting Eqn 2 from Eqn 3

(4x+4y)-(3x+4y)=72-59\\4x+4y-3x-4y=13\\x=13

The college student took 13 courses of 3 credit hours.

minimum : (smallest number) = 121
Q1 : 125
Q2 (median) : (132 + 135) / 2 = 267/2 = 133.5
