Answer:
0.0323 = 3.23%. Is unusual
Step-by-step explanation:
Using the normal distribution we can find z value with the mean and standard deviation as follows. x is the value we want to know its probability
z = (x - mean)/standard deviation
z = (5-8.54)/1.91
z = -1.85
Using z tables for normal distribution, for z = 1.85, we have an area under the curve of 0.9677. Since we want to know the probability for 5 minutes or less, we have to substract from
p = 1- 0.9677
p = 0.0323
An event with a probability less than 5% is considered unusual.

Answer:
62.8 in
Step-by-step explanation:
Circumfrence=pi x diameter
3.14 x 20=62.8
Yeah it's true, a point has no width, hight, or depth
Answer:
The line intersecting is a transversal and x is 44 degrees.
