Answer:
The estimated average temperature for 7 month is 20 °F.
Step-by-step explanation:
The given graph shows the relation between number of months and average temperature.
The equation for the line of best fit is
Where, x is number of months and y is average temperature(°F).
We need to find the average temperature for 7 month.
Substitute x=7 in the given equation of best fit line.
Therefore the estimated average temperature for 7 month is 20 °F.

Answer:
Future value = $755.61 ( to the nearest cent)
Step-by-step explanation:
The formula for calculating the future value of an invested amount compounded periodically for a number of years is given as:
where:
FV = future value = ???
PV = present value = $575
r = interest rate in decimal = 5.5% = 0.055
n = number of compounding periods per year = quarterly = 4
t = time of investment = 5 years
∴
∴ Future value = $755.61 ( to the nearest cent)
