Answer:
5. not a function
6. function
7. not a function
8 function
9. not a function
10 function
Step-by-step explanation:
5. this fails the vertical line test. Since a vertical line would touch more than one point this is not a function
6. this is a function. Each input (or x) has only one output, so it is a function
7. This is not a function . X=2 goes to more than one y value x =2 goes to y=5 and y=6. so it is a relation not a function
8. this passes the vertical line test. Since a vertical line does not touch more than one point this is a function
9. This is not a function . X=5 goes to more than one y value x =5 goes to y=-4 and y=1. so it is a relation not a function
10. this is a function. Each input (or x) has only one output, so it is a function
Answer:
1/40
Step-by-step explanation:
A bag contains 5 blue, 3 red, and 8 green marbles
You have (5+3+8=16) marbles
P(red 1) = red/total = 3/16
You do not replace it
A bag contains 5 blue, 2 red, and 8 green marbles
You have (5+2+8=15) marbles
P(red 2nd) = red/total = 2/15
P(red 1, red 2) = P (red 1)* P (red 2) = 3/16 * 2/15
=1/40
Answer:
The price for each latte was $4.50
Equation: 45-18=6x
There are 24 hours in a day. 25% is 25 / 100
% can always be replaced by divide by 100.
25/100 * 24 = 25*24/100 = 600 / 100 = 6
Therefore someone spends 6 hours a day in school.
