Answer:
A. (6÷3) + 12
Step-by-step explanation:
Because with the 12 at the end, that's more.
Answer:
Two double roots in this case.
I could say 4, but you have a pair of double roots x = 6 and x = -2
Step-by-step explanation:
x = 6 is a double root of f(x)
x = -2 is a double root of f(x)
Answer: Perpendicular bisector
Step-by-step explanation:
The perpendicular bisector of a side of a triangle is a line perpendicular to the side and passing through its midpoint. The three perpendicular bisectors of the sides of a triangle meet in a single point, called the circumcenter . A point where three or more lines intersect is called a point of concurrency.
Answer:
For this case we want to test if the the average monthly income of all students at college is at least $2000. Since the alternative hypothesis can't have an equal sign thne the correct system of hypothesis for this case are:
Null hypothesis (H0): ![\mu \geq 2000](https://tex.z-dn.net/?f=%5Cmu%20%5Cgeq%202000)
Alternative hypothesis (H1): ![\mu](https://tex.z-dn.net/?f=%5Cmu%20%3C2000)
And in order to test this hypothesis we can use a one sample t or z test in order to verify if the true mean is at least 200 or no
