Suppose the daily closing price of a corporation's shares is approximately normally distributed over the course of a year, where the mean is $271.35 and a standard deviation of $31.17
Explain whether the range $220 to $320 represent about 94% of the daily closing prices of the corporation's
shares for that year. Round all amounts to four decimal places as needed.

A) No, because the value of $220 is -1.6474, and the area under the normal distribution and to the left of
-1.6474 is approximately 0.0497

B) No, because all of the values in the range are within two standard deviations of the mean

C) No because the value of $220 is - 1.6474 and the value for $320 is 1.5608 The area under the normal
distribution between 3-1.6474 and 1.5608 is approximately 0.8910

D) Yes because the value of $320 is 1.5608 and the area under the normal distribution and to the left of
1.5608 is approximately 0.9407

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
