Step-by-step explanation:
It is an abservational study because she is only watching and not asking the all or a group of employees to tell her their response to what she wants to know.
It is a convenience sample because subjects are selected because of their closeness to the researcher.
Discriminant = b^2 - 4ac, where a, b and c come from the form of the quadratic equation as ax^2 + bx + c
Discriminant = (4)^2 - 4(1)(5)
= 16 - 20
= -4
-4 < 0, therefor there are no roots
(If the discriminant = 0, then there is one root
If the discriminant > 0, there are two roots, and if it is a perfect square (eg. 4, 9, 16, etc.) then there are two rational roots
If the discriminant < 0, there are no roots)
H= -16
Step-by-step explanation:
Answer:
For 5/11 shade in the third bubble (0.45 repeating)
Answer:
$100
