The ages of pennies at a particular bank follow a nearly normal distribution with mean 10.44 years with standard deviation 9.2 years. Say you take random samples of 30 pennies, find the mean age in each sample, and plot the distribution of these means. Which of the following are the best estimates for the center and spread of this distribution? a. mean = 10.44, standard error = 9.2
b. mean = 10.44, standard error = 9.2/30 = 0.31
c. mean = 10.44/30 = 0.348, standard error = (9.2/30)2 = 0.094
d. mean = 10.44, standard error = 9.2/30 = 1.68

it has the same slope and a different y-intercept

hope this : )

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
