Answer: Choice A) All points with an x-value of 3 are located in Quadrant I.
We can show it is false through the use of a counter example. For instance, the point (3, -5) is not in quadrant 1, but rather in quadrant 4.
We would need to say "all points with x value 3 and positive y value" to ensure the point is in quadrant 1.
Answer:
If there are 10 students taking only chemistry, 9 students taking only physics, and 5 students only taking both chemisty and 16 students are taking neither; I would add 10+9+5+16=40 (total students) and divide 10/40 (25% chemistry) 9/40 (22.5% physics) 5/40 (12.5% both) 16/40 (40% neither)
Step-by-step explanation:
1. Determine a single event with a single outcome.
2. Identify the total number of outcomes that can occur.
3. Divide the number of events by the number of possible outcomes.

Answer/Step-by-step explanation:
✔️Reference angle = 50°
Opposite side length = y
Hypotenuse = 8 cm
Adjacent = x
Thus, applying CAH we can find x as shown below:
Cos 50 = adj/hyp
Cos 50 = x/8
8 × cos 50 = x
x = 5.1 (to 1 decimal point)
Thus, applying SOH, we can find y as shown below:
Sin 50 = opp/hyp
Sin 50 = y/8
8 × Sin 50 = y
y = 6.1 (to 1 decimal point)
