You're answer will be C 13x2+12xy+9y2
Answer:
C
Step-by-step explanation:
Step-by-step explanation:
z-score of X = 6150
z-score of X = 6350
P(X<6150) + P(X>6350)
=P(z<-0.4) + P(z>-0.4)
=0.3446+0.3446
=0.6892
Answer: y>0
Step-by-step explanation:
Let's look at the graph. If we do the vertical line test, we can figure out that YES, it is a function, so option b and c are already out of the picture.
Now, to find the domain, look at the graph and shade it back to the x-axis. The domain includes every number greater than 3, so the domain is x>3.
To find the range, take a look at the graph and shade it back to the y-axis. The range includes every real number greater than 0, so the range is y>0
This means that d is the answer.
I really hope this helps!
Best wishes :)
