Answer:
A. 0.2
Step-by-step explanation:
First make the table.
<u>10-grade</u> <u>11-grade</u> <u>12-grade</u> <u>Total</u>
<u>Woodson high school </u> | 110 | 120 | 80 | 310 |
<u>Valley high school </u> | 180 | 150 | 120 | 450 |
<u>Riverside high school </u> | 160 | 140 | 200 | 500 |
<u>Total </u> | 450 | 410 | 400 | 1260 |
Question: In decimal form, to the nearest tenth, what is the probability that a randomly selected riverside high school student is in twelfth grade?
First, find 12-grade and riverside high school number. 200. Take the total lined up with total number, which is 1260, and divide 200 divided by 1260.
200/1260=0.2
The answer is 0.2.
Hope this helps!

therefore your answer is 40
Answer:
5). x = 11.9°
6). x = 27.2°
Step-by-step explanation:
5). By applying cosine rule in the given triangle,
cos(32)° = 
cos(32)° = 
x = 14cos(32)°
x = 11.87
x ≈ 11.9°
6). By applying sine rule in the given triangle,
sin(54°) = 
sin(54°) = 
x = 
x = 27.19°
x ≈ 27.2°
