Answer: 
Step-by-step explanation:
Let
denotes the average braking distance for a population of small car.
Given : It is advertised that the average braking distance for a small car traveling at 65 miles per hour equals 120 feet.
i.e. 
Objective of test : Whether the statement made in the advertisement is false
i.e.
Since '=' signs is contained by Null hypothesis and alternative hypothesis is against it.
So the null and the alternative hypotheses for the test will be:

On an isosceles trapezoid, the two sides that are not parallel to each other will be exactly the same length. If this is true, than it would be create a symetric trapezoid. The diagonals would be the same length. The bases of any trapezoid are parallel, so this is true. The diagonals cannot possibly be perpendicular because the 2 nonparallel sides would be slanted. So, the answer is the 3rd choice.

Answer:
Can' possible......
Step-by-step explanation:
Let suppose the numbers are:
x
x + 1
x + 2
Now according to given condition:
x + x +1 + x+ 2 = -206
By adding we get:
3x + 3 = -206 Subtracting 3 from both sides:
3x + 3 - 3 = -206 -3
Both terms on right side have negative sign so we will add them. (answer will have negative sign.)
3x = -209
Dividing both sides by 3:
x = -209/3
x = -69.6666
that is not an integer so the question is wrong.
I hope it will help you!
