In this diagram below, DE is parallel to XY. What is the value of y?
2 answers:
Answer: The value of y is 122°
Step-by-step explanation:
Since we have given that
DE is parallel to XY
So, Corresponding angles will be equal and vertically opposite angles are equal too.
So, x=122° (∴ Vertically opposite angles are equal )
and x=y=122° (∵ Corresponding angles are equal )
Hence, The value of y is 122°

3) This is definitely a positive association, but the question is - is it linear?
Since a somewhat straight line can be drawn through the points, it is linear.
<span>Answer: positive linear association
</span>
4) Find the slope using the formula
m = 43 - 48/ 4 - 2 = -5/2 = -2.5
Negative association, but is it linear? Lets find out
Oh no! It seems that their is not a pattern in the association, so its nonlinear!
Answer: Negative nonlinear association
5) <span>
m = 80 - 66/ 5 - 3
m = 14/2
m = 7
Positive! But is it linear??
Let us draw a graph this time.
I know my graph is messy, but can you see the nonlinear-ness? It doesnt form a straight line!
Answer: Positive nonlinear association

Answer:
<h2>a. $8.83</h2><h2>b. $136.83</h2><h2>The second option will be the right answer.</h2>Step-by-step explanation:
a.
The total tax which is need to be paid is 6.9% of the listed price.
6.9% of 128 = = 8.832 ≅ 8.83
b.
The person, who is going to buy a pair of boots, needs to pay the listed price as well as the required tax.
The total cost of the pair of boots is = listed price + tax = $(128 + 8.83) = $136.83
