Answer:
A and B
Step-by-step explanation:
The minimum occurs at the turning point ( vertex )
The coordinates of the vertex are (1, - 2 ) → A
The x- intercepts are the points where the graph crosses the x- axis
This occurs at (3, 0 ) and (- 1, 0 ) → B
The axis of symmetry is a vertical line passing through the vertex
Equation of axis of symmetry is x = 1 , not y = - 2
(1, - 2 ) is a minimum not a maximum , see above
Using the proportion concept, it is found that:
- According to Tyler's sample, the estimate is of 0.2 = 20%.
- According to Kyran's sample, the estimate is of 0.17 = 17%.
- Due to the higher sample size, Kyran's estimate is more accurate.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and larger sample sizes lead to more accurate predictions.
In Tyler's sample, 2 out of 10 students would dye their hair blue, hence:
p = 2/10 = 0.2.
In Kiran's sample, 17 out of 100 would, hence:
p = 17/100 = 0.17.
Due to the higher sample size, as 100 > 20, Kyran's estimate is more accurate.

OK so for this it will be simple
1,000 divided by 200 is 5
so if the plane took 5 hours to do 1,000 miles then the plane was traveling at option A. 200 miles per hour.
Step-by-step explanation:
14 < 6×?
6×3=18
therefore anything above 3 multiplied by 6 would be greater in value than 14
