The diagram of the lawn and the shed is shown below.

The area of the lawn needed to be mowed equals to the area of the yard minus the area of the shed

The area of the yard = (5x)(13x-4) = 65 x^{2} -20x
The area of the shed = (2x)(2x+4)=4 x^{2} +8x

The area of the lawn = 65 x^{2} -20x-(4 x^{2} +8x)
The area of the lawn = 65 x^{2} -20x-4 x^{2} -8x
The area of the lawn = 61 x^{2} -28x

vredina [299]

Answer:

\bar X= \frac{\sum_{i=1}^n X_i}{n}

The reason is because we assume that each week have the same weight and replacing we got:

\bar X= \frac{190+163+327+205}{4}= 221.25

And the best option would be:

D. 221.25

Step-by-step explanation:

For this case we have the following data given

Week       1       2         3       4

Minutes  190   163   327   205

For this case we can find the mean with the following formula:

\bar X= \frac{\sum_{i=1}^n X_i}{n}

The reason is because we assume that each week have the same weight and replacing we got:

\bar X= \frac{190+163+327+205}{4}= 221.25

And the best option would be:

D. 221.25
