Given:
4 relations in the options.
To find:
The relation which represents a function.
Solution:
We know that, a relation is a function if there exist a unique output value for each input value.
In option A, we have two output values y=-5 and y=1 for single input value x=-1. So, it is not a function.
In option B, we have two output values y=2 and y=4 for single input value x=3. So, it is not a function.
In option C, we have two output values y=1 and y=7 for single input value x=-1. So, it is not a function.
In option D, we have unique output value for each input value. So, it is a function.
Therefore, the correct option is D.
Step-by-step explanation:
given that
p= "I do my chores"
q= "I get my allowance."
The statement that uses p as hypothesis is, if "I do my chores", which leads to the conclusion of "I get my allowance."
hence the test/ hypothesis is if "I do my chores", i get my allowance
I only know D. but I'll try to figure out the rest too. D. 9 years old
Answer: 0.03%
Explanation: 3/100
Answer:7.125 min
Step-by-step explanation:
Given
Resting time =24 min
Personal time=10 min
Delay=14 min
Observed Time=6min/cycle
Performance Rating=95%
Allowance Time=Rest time+Personal time+delay
Allowance time=24+10+14=48 min

Allowance Factor=
Calculate the Normal Time
Normal time=Observed time
personal Time=6\times 0.95=5.7 min
Standard time=Normal time
Allowance Factor
Standard time =
=7.125 min
