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.
Substitute x to be 7 (for month 7) and work out the equation:
y = -13(7) + 111
y = -91 + 111
y = 20
Your answer is 20 degrees Fahrenheit.
(0,-4-4√6) and (0,-4+4√6)
To determine the coordinates as Jon wants to place it 14 points away
√10^2+(a+4)^2 = 14
100+(a+4)^2 = 196
(a+4)^2 = 96
a+4 = ±√96
a+4 = ±4√6
a= -4±4√6
