Answer: 68.27%
Step-by-step explanation:
Given : Mean value of land and buildings per acre from a sample of farms :


The data set has a bell-shaped distribution. i.e. it follows Normal distribution.
Using
, for x= 1300 , we have
For x= 1700 ,
Using standard normal z-value table,
P-value = P(-1<z<1)=
[Round to nearest 4 decimal places.]
i.e. The percent of farms whose land and building values per acre are between $1300 and $1700 = 68.27%

<h3>#8</h3>
<u>Supplementary:</u>
- 2x + 6x + 20 = 180
- 8x = 160
- x = 20
The slope of a line includes a x and y axis, or y/x. Your two answers are -7/4 and -8/5. Hope that helps!
