Answer: yˆ 0.0371x2 - 0.5691x - 0.341
Step-by-step explanation:
Using the quadratic regression equation calculator,
The quadratic regression equation is :
yˆ 0.0371x2 - 0.5691x - 0.341
Taking the form Ax^2 + Bx + C
A = 0.0371
B = -0.5691
C = -0.3410
Answer:
the thalia age be 19 years
Let us assume her brother age be x
Now the thalia age be x - 3
Now the equation would be
x + x - 3 = 41
2x = 41 + 3
2x = 44
x = 22
thalia age be
= 22 - 3
= 19
Hence, the thalia age be 19 years
And, her brother age be 22 years
The same is to be considered
