Answer: 
Step-by-step explanation:
Given
The point C 
is rotated 
clockwise about the origin
If a point is rotated about the origin, then the sign of the co-ordinates changes without changing the order of coordinates.
So,C becomes C' after the rotation.
4,080,499 rounded to the nearest thousand is 4,080,000.
For the first one it's 90.5, I know cause I just took the test and it's right. The second one I'm not sure..
Answer:
0.8
Step-by-step explanation:
P(AP statistics) = 65%
P(AP Calculus) = 45%
P(AP statistics n AP Calculus) = 30%
Probability of AP statistics or AP Calculus but not both :
Probability of event A or B :
P(AUB) = p(A) + p(B) - p(AnB)
P(AP statistics U AP Calculus) = P(AP statistics) + P(AP Calculus) - P(AP statistics n AP Calculus)
= 0.65 + 0.45 - 0.30
= 0.8
= 80%
