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%

Step-by-step explanation:
According to the Question,
Given that, A retired couple has up to $50,000 to invest. As their financial adviser, you recommend that they place at least $35,000 in Treasury bills yielding 1% and at most $10,000 in corporate bonds yielding 3%.
Therefore,
Let, x be the amount of money invested in Treasury bills
y be the amount invested in corporate bonds
Thus, the system of equations of linear inequalities is
x + y ≤ 50000
x ≥ 35000
0 ≤ y ≤ 10000
For, the graph of the system of equations of linear inequalities describes the possible amounts of each investment.
