Answer:
1.5 + 1.3228756555323i
1.5 - 1.3228756555323i
Step-by-step explanation:
y = ax^2 + bx + c
a = 1, b = -3, c = 4
Using the quadractic formula:

Note: Kindly ignore the A in the above solution ^
Hence, there is no real solution. It has complex roots.

Answer:
The coefficient of correlation=0.5
Step-by-step explanation:
We are given that
Covariance between the variable x and y=18
Variance of x=16
Variance of y=81
We have to find the coefficient of correlation
We know that
Coefficient of correlation

Using the formula



Hence, the coefficient of correlation=0.5
Match bases
if a^x=b^x where x=x then a=b
hmmm
1/8=8^-1=(2^3)^-1=2^-3
so
2^n=2^-3
n=-3
