The distance between the two planes will be 800 miles.
It should be noted that the total speed of the two planes will be the sum of their individual speeds. Also, the planes have 1 hour to meet each other.
From the information given, the distance between the planes is 200 miles after they flew for 45 minutes. Therefore, the remaining distance will be:
= 1 hour - 45 minutes = 15 minutes.
The distance between the planes will then be:
= 200/15 × 60
= 200 × 4
= 800 miles
Therefore, the distance between the two planes will be 800 miles.

Which of the following equations represents the axis of symmetry for the parabola shown? (5 points)y = 10x
x = 10
x = y + 10
y = x + 10
The following equations that best represents the axis of symmetry for the parabola shown is x = 10.
Answer: Choice B
There is not convincing evidence because the interval contains 0.
========================================================
Explanation:
The confidence interval is (-0.29, 0.09)
This is the same as writing -0.29 < p1-p1 < 0.09
The thing we're trying to estimate (p1-p2) is between -0.29 and 0.09
Because 0 is in this interval, it is possible that p1-p1 = 0 which leads to p1 = p2.
Therefore, it is possible that the population proportions are the same.
The question asks " is there convincing evidence of a difference in the true proportions", so the answer to this is "no, there isn't convincing evidence". We would need both endpoints of the confidence interval to either be positive together, or be negative together, for us to have convincing evidence that the population proportions are different.
You would have to divide by 3.14 to find the radius squared, and to find the diameter, just add the radius plus the radius.
Your right it’s an obtuse angle
