A forester measured 24 of the trees in a large woods that is up for sale. He found a mean diameter of 10.5 inches and a standard deviation of 4.6 inches. Suppose that these trees provide an accurate description of the whole forest and that a Normal model applies.

a. Draw the Normal model for tree diameters.
b. What size would you expect the central 95% of all trees to be?
c. About what percent of the trees should be less than an inch in diameter?
d. About what percent of the trees should be between 5.7 and 10.4 inches in diameter?
e. About what percent of the trees should be over 15 inches in diameter?

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
