erica [24]

Answer:

Mean = 10724.29\ mi

Step-by-step explanation:

Given

n = 7 --- days

See attachment for odometer readings

Required

The mean of the distance

Mean is calculated as:

Mean = \frac{\sum x}{n}

So, we have:

Mean = \frac{10150 + 10211 + 10424 + 10769 + 10884 + 11155 + 11477}{7}

Mean = \frac{75070}{7}

Mean = 10724.2857143

Approximate

Mean = 10724.29\ mi

SVEN [57.7K]

Answer:

length = 200 m

width = 400 m

Step-by-step explanation:

Let the length of the plaing area is L and the width of the playing area is W.

Length of fencing around three sides = 2 L + W = 800

W = 800 - 2L ..... (1)

Let A is the area of playing area

A = L x W

A = L (800 - 2L)

A = 800 L - 2L²

Differentiate with respect to L.

dA/dL = 800 - 4 L

It is equal to zero for maxima and minima

800 - 4 L = 0

L = 200 m

W = 800 - 2 x 200 = 400 m

So, the area is maximum if the length is 200 m and the width is 400 m.
