Answer:
1. No, because each x value can only have one y value (one-to-one relationship).
2. No, because each x value can only have one y value (one-to-one relationship).
3. Yes, because one member of the domain is assigned to one member of the range.
Step-by-step explanation:
6x^2+14x+4
First factor out all numerical factors (=2 in this case)
2(3x^2+7x+2)
look for m,n such that m*n=3*2, m+n=7 => m=6, n=1
2(3x^2+6x + 1x+2)
Factor 3x^2+6x into 3x(x+2)
2( 3x(x+2)+1(x+2) )
factor out common factor (x+2)
2(x+2)(3x+1)
=>
6x^2+14x+4=2(x+2)(3x+1)
Answer:
26.3 feet
Step-by-step explanation:
We have to first find the length of the side of each tile.
The area of each tile is 19.2 
.
The area of a square is:
A = 
where L = length of side
Therefore:
6 tiles will be lined end to end to construct the walkway, hence, the length of the walkway is:
6 * 4.38 ≅ 26.3 feet
Answer:
She used the simple random sampling technique because there was no condition attached to the samples she took.
Step-by-step explanation:
we have basically four types of sampling
1.Simple random sampling.
2.Systematic sampling.
3.Stratified sampling.
4.Cluster sampling.
simple Random sampling: is a sampling technique where every item in the population has an even chance and likelihood of being selected in the sample.
