1 to 50
Step-by-step explanation:
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%

Reading the question it is obvious that the blue region lies inside the larger square and outside the smaller square.
The region between the two squares is the blue region.
Step 1
Find the area of both squares.
Area of larger square = 8 x 8 = 64 in²
Area of smaller square = 2 x 2 = 4 in²
Subtracting the area of smaller square from larger one, we can find the area of blue square and further we can find the said probability.
Area of blue region = 64 - 4 = 60 in²
The probability that a randomly chosen point lies within the blue region = Area of blue region/Total area available
Therefore,
the probability that a point chosen at random is in the blue region
= 60/64 -------> 0.9375
the answer is
0.9375
60 0/0 8=7.5 your answer is 7.5
