Answer:
0.52
Step-by-step explanation:
Given the regression line :
Test score^ = 698.9 - 2.28STR
T statistic on slope Coefficient = 4.38
The standard error on slope Coefficient :
2.28 / 4.38
= 0.5205479
= 0.52
Answer:
B. The fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. The roots are x=3±i√11/2 .
Step-by-step explanation:
We know that,
Fundamental theorem of algebra states that ' a polynomial of degree n will have n number of roots'.
Since, the polynomial
has degree 2, so it will have 2 roots.
We know that the polynomial
has roots given by
.
So, the roots of polynomial
will be,

i.e. 
i.e. 
i.e. 
i.e. 
Hence, the roots are given by 
So, option B is correct.
Answer:
x = 4.
Step-by-step explanation:
5x - 3.5 = 3x + 4.5
5x - 3x = 4.5 + 3.5
2x = 8
x = 4.
