Answer:
Trend lines are lines used to approximate the general shape of a scatter plot. A positive trend line tells us the scatter plot has a positive correlation. A negative trend line tells us the scatter plot has a negative correlation.
Answer:
a. $49
b. $74.28
c. No
Step-by-step explanation:
The computation is shown below:
a. The store price is
= Purchase price + markup
= $35 + $35 × 40%
= $35 + $14
= $49
b. The price paid is
Since there is a markup of 40% and when it is added to 100% of cost so the selling price is 140% of the cost or 1.40 of the cost
Now the price paid is
$104 = 1.40 × cost
So, the cost is
= $104 ÷ 1.40
= $74.28
c. Now the markup is
= $100 - $75
= $25
The markup percentage is
= $25 ÷ $75
= 33.33%
No the store does not markup the price by 40%
Answer:
The probability of the first draw is 100%, because the bead will be either red or white. For the second draw, a different color must be drawn.
So, if draw 1 is white, then the probability of draw 2 being red is 7/10. and if the first draw is red, then the probability of draw two being white is 5/10.

Answer:
(-2, -1).
Step-by-step explanation:
y = x² + 4x + 3
Completing the square:
y = (x + 4/2)^2 - (4/2)^2 + 3
y = (x + 2)^2 - 4 + 3
y = (x + 2)^2 - 1.
This is vertex form and the coordinates of the vertex are (-2, -1).
