Answer:
Step-by-step explanation:
While working at his neighborhood math tutoring center researching the comprehension level of the students Dion investigated that the distribution of the student test scores are normally distributed with a mean of 79.13 and a standard deviation of 6.34. What is the probability that the student scores less than 60.11
We solve using z score formula
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
z = 60.11 - 79.13/6.34
(-5, 4)
You can get this by finding the vertex at -b/2a for x value and plugging in to find the y value.

notice that for the perimeter we didn't include the segment BC, because the perimeter of a figure is simply the outer borders.
