Answer:
<em><u>The number of students that like only Nokia </u></em>
<h2>= 30</h2>
Step-by-step explanation:
consider N the number of students who like Nokia → N=?
T the number of students who like Techno → T=35
Statement 1: In a class of 40 students, 5 like neither Nokia nor Techno
we can translate it like this: 35 student like Nokia or Techno
we can note it like this : T∪N= 35
Statement 2: 30 like Techno and Nokia
we can note it : T∩N = 30
using a rule concerning the number of element of a set :
T∪N = N + T - T∩N
then
35 = N + 35 - 30
⇒ N - 30 = 0
⇒ N = 30
Answer:
C. y = [x] - 6
Step-by-step explanation:
The point that lies on the x-axis is sitting at (6,0), 6 being x and 0 being y, when you relpace the [x] with 6 and do the equation, you will get 0, which is what y happens to be equal to.
x = 6
y = [6] - 6 = 0
y = 0
