Answer: Non of the option.
Step-by-step explanation:
The given equation is
4x^3 - 6x^2 + 15x + 2 = 0
Let's test 1, if it's one of the root. I.e
If x = 1
4 - 6 + 15 + 2 = 15
Positive 1 is not a root to the equation
If x = - 1
-4 - 6 - 15 + 2 = - 23
Negative 1 is not a root
If x = 2
4x8 - 6×4 + 15×4 + 2
32 - 24 + 30 + 2 = 40
Positive 2 is not a root
If x = - 2
4×(-8) - 6×4 - 15×2 + 2
-32 - 24 - 30 + 2 = -84
Negative 2 is not a root
If x = 3
4×27 - 6×9 + 15×3 + 2
108 - 54 + 45 + 2 = 101
Since non of them tend to zero, non of the option is a root of the equation
This is in 2 point form
(y2-y1)=m(x2-x1)
(9-5)=3/5(x-3)
x=29/3

Hello your has some missing information attached below is the missing information
answer : 2355.62
Step-by-step explanation:
<u>Calculating the residual for Palm Beach county</u>
Given that total votes = 430772
and The regression equation = 56.115131 + 0.0023197 * Total Votes
The predicted Buchanan = 56.115131 + 0.0023197 * 430772 = 1055.377
while the Actual Votes Buchannan = 3411
Residual for Palm Beach county = Actual votes Buchannan - Predicted
= 3411 - 1055.377 = 2355.62
Note :
b0: 56.1132
