Answer:

Both the mean and the median


Step-by-step explanation:

Whichever measure, mean or median, is higher, Ari will benefit from that.


<u>Median:</u>

Median is the "middle value" of the list when arranged from least to greatest.

<em>Since there is 6 numbers, the middle number is between the 3rd and 4th number. Hence, we take the average of the 3rd and 4th number.</em>

Arranged from least to greatest: 73, 76, 80, 88, 90, 97

Average of 3rd and 4th is the Median = \frac{80+88}{2}=\frac{168}{2}=84


<u>Mean:</u>

Mean is the sum of all the number divided by the number of numbers (6).

So we have:

Mean = \frac{88+73+97+76+90+80}{6}=\frac{504}{6}=84

Mean is 84


Since Mean and Median are both same (84%), both will be best measure of center for Ari.

A home gardener estimates that 18 apple trees will produce an average yield of 80 apples per tree. But because of the size of th
aliina [53]

19 trees should be planted to maximize the total

<h3>How many trees should be planted to maximize the total</h3>

From the question, we have the following parameters:

Number of apples, x = 18

Yield, f(x) = 80 per tree

When the number of apple trees is increased (say by x).

We have:

Trees = 18 + x

The yield decreases by four apples per tree.

So, we have

Yield = 80 - 4x

So, the profit function is

P(x) = Apples * Yield

This gives

P(x) = (18 + x) *(80 - 4x)

Expand the bracket

P(x) = 1440 - 72x + 80x - 4x^2

Differentiate the function

P'(x) = 0 - 72 + 80 - 8x

Evaluate the like terms

P'(x) = 8 - 8x

Set P'(x) to 0

8 - 8x = 0

Divide through by 8

1 - x = 0

Solve for x

x = 1

Recall that:

Trees = 18 + x

So, we have

Trees = 18 + 1

Evaluate

Trees = 19

Hence, 19 trees should be planted to maximize the total
