An injective function is not a function that is surjective. This means that you want a function that has a unique output for each input, that doesn't cover the natural numbers.
In formal terms a function [Math Processing Error] is injective if [Math Processing Error] implies [Math Processing Error].
We also know that it's not surjective because no value maps to [Math Processing Error] (or any odd number) since if [Math Processing Error], then [Math Processing Error]. However, since [Math Processing Error], the function isn't surjective.

Answer: 5.5
Step-by-step explanation:
3m+13=29.5
Answer: z equals 0.60 minus 0.72 all over the square root of the quantity 0.72 times 0.28 over 80
Step-by-step explanation:
let p be the population proportion of students complete their homework on a daily basis.
As per given , we have
p= 0.72
sample size : n= 80
Sample proportion : 
Test statistic for proportion:
i.e.
i.e.
That is , z equals 0.60 minus 0.72 all over the square root of the quantity 0.72 times 0.28 over 80
Answer: 2/3, 29/36, 5/6, 8/9
Step-by-step explanation:
You find the common denominator you could use for all fractions. In this instance, you can use 36 for the common denominator.
2/3: 36/3=12, 2x12=24 therefore 2/3 becomes 24/36.
29/36: you leave this one alone, it has already been simplified.
5/6: 36/6=6, 6x5=30 therefore 5/6 becomes 30/36.
8/9: 36/9=4, 8x4=32 therefore 8/9 becomes 32/26.
E would be your answer because the two negatives become a positive
