Answer: y=4

Step-by-step explanation:

There are different ways to solve this problem. One is to know how functions work, and the other is to create a function and plug in x=1. In this case, we are lucky that they gave us a point where x=1. The point is (1,4).

Knowing a function, you plug in an x and output a y. In the point (1,4), you are inputting 1 and outputting 4.

This is the same things as saying f(1)=y, or f(1)=4. Therefore, the value is y=4.

Two sections of a class took the same quiz. Section A had 15 students who had a mean score of 80, and Section B had 20 students
Alex17521 [72]

Answer:

85.7

Step-by-step explanation:

Given that two sections of a class took the same quiz. Section A had 15 students who had a mean score of 80, and Section B had 20 students who had a mean score of 90.

Section A total score = 15*80=1200

Section B total score 20*90 = 1800

Overall total score=3000

Overall total students = 15+20 =35

Hence overall mean = \frac{3000}{35} \\=85.7143

rounding off to one decimal place

overall mean = 85.7
