Answer:
2.28%
Step-by-step explanation:
Mr. bowens test is normally distributed with a mean (μ) of 75 and a standard deviation (σ) of 3 points.
The z score is used in probability to show how many standard deviation is a raw score below or above the mean. The formula for the z score (z) is given by:
For a raw score (x) of 81 points, the z score can be calculated by:
Therefore from the normal probability distribution table, the probability that a randomly selected score is greater than 81 can be given as:
P(x > 81) = P(z > 2) = 1 - P(z < 2) = 1 - 0.9772 = 0.0228 = 2.28%

In order to get as many tickets they need 15 business class tickets and 12 economy class tickets (700x15=10,500)(375x12=4500) Which when you add those two makes 15,000.
- Its key to copying a specified line is to open your beacon to the length of both the section, then use that amount of entrance to label off another section of the same length.
- To bisect a segment or angle means to divide it into confocal scanning parts. A line segment's bisector would then pass thru the midpoint of its segment.
- Once copying a segment as well as bisecting a section, its Draw a ray including one end-point step will be the same.
- So if copying a line and bisecting a line segment, this same needle of both the compass is placed mostly on-line segment's end.
- Therefore, the "Draw a ray with one endpoint" choices are correct, and the other choices were incorrect.

The original statement is true by the definition of what constitutes a right angle. It's simply set up this way.
The contrapositive would be the statement "if the angle does not measure 90 degrees, then the angle is not a right angle" which is also a true statement. Example: a 37 degree angle is not a right angle.
Note: the original conditional "If P, then Q" would have the contrapositive be in the form "If not Q, then not P". We flip P and Q, and stick "not"s in front of both parts.
So this is why the answer is choice D
