The mean value of land and buildings per acre from a sample of farms is $1300, with a standard deviation of $200. the data set has a bell-shaped distribution. assume the number of farms in the sample is 74. use the empirical rule to estimate the number of farms whose land and building values per acre are between $1100 and $1500.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
