this question is kind of wrong and incorrect but...
if it "was" constant then you would be going
per hour: 15 miles per hour
per minute: 0.25 miles per minute
It answer is a combination
Answer:
The correct option is 4.
4) Doing two distance formulas to show that adjacent sides are not the same length.
Step-by-step explanation:
Parallelogram is a quadrilateral which has opposite sides equals and parallel. Example of a parallelogram are rhombus, rectangle, square etc.
We can prove that a quadrilateral MNOP is a parallelogram. If we find the slopes of all four sides and compare those of the opposite ends, same slopes would indicate the opposite sides are parallel, hence the quarilateral is a parallelogram. We can also find the distance of two opposing sides, and slopes of twp opposing sides to determine whether it is a parallelogram or not. The most difficult approach is that diagonals bisect each other at same point.
However, using only two distance formulas will not give us enough information to determine whether a side is parallel or not.

Under a normal distribution curve, if 70% of the people fall to the right of the observation point, then 30% of the people would fall to the left of the observation point. Note, the observation point is the number we are looking for in this instance(how long it takes to find a parking space).
We'll need to use a z table and the formula for a z score to find what we are looking for. First, convert 30% to 0.30 and refer to a standard z table that represents the area under a normal curve to the left of specific z scores. We'll need to look in the body of the table and find the closest decimal value compared to our 0.30. Once you find this decimal number, reference the row and column values to obtain the z score. Looks like this will be -0.53.
Now we can use the z score formula to find our observation point:
z score = (x - Mean)/standard deviation, where x represents the observation point we're looking for!
Substituting into the formula we have:
Solving this equation for x, we find x = 2.94
This represents our observation point and we can assume that 70% of people take more than 2.94 minutes to find a parking space.
