Answer:
Your teacher is correct.
Step-by-step explanation:
Common knowledge about coordinates:
The first number in a coordinate is the "x coordinate".
The second number is the "Y coordinate".
The X axis is the horizontal line.
The Y axis is the vertical line.
The origin is the middle of the two axis's.
For A, the x coordinate is -4. You go right on the horizontal line because it is a negative number. The y coordinate is 4, so you go up from -4 to 4 because it is a positive number. there, you'll get your coordinate (-4 , 4).
For B, because the x coordinate is 0, you don't move at all, and you stay on the x origin. The y coordinate is 6, so you go up from the origin to 6. There, you'll have (0, 6).
C is pretty self explanatory if you understand the concept.

Answer:
y = 12.9
Step-by-step explanation:
To find the value of the side y, simply apply the law of cosines.
y^2 = (14)^2 + (9)^2 - 2(14)(9)cos(64)
y^2 = 196 + 81 - 110.47
y^2 = 166.53
y = 12.9
Therefore, your solution should be y = 12.9

I think u need to subtract both up and both down
Answer:
This interval is between 1.5 and 15.5.
Step-by-step explanation:
Tchebysheff's Theorem
The Tchebysheff's Theorem can also be applied to non-normal distribution. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is given by 
.
In this question, we have that:
Mean = 8.5
Standard deviation = 3.5
The manager wants to publish an interval in which at least 75% of these values lie.
By the Tchebysheff's Theorem, at least 75% of the measures are within 2 standard deviations of the mean.
8.5 - 2*3.5 = 1.5
8.5 + 2*3.5 = 15.5
This interval is between 1.5 and 15.5.
