Hello here is a solution :
<span>x² − 8x − 4 = 0.
</span><span>quadratic equation ax²+bx+c = 0 when : a=1 and b= -8 and c = -4
discriminant : d = b²-4ac d= (-8)²-4(1)(-4) =64+16 =70
x= (-b-rot(d))/2a </span>x'= (-b+rot(d))/2a .......conrinu

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
