Actually there is enough information to solve this
problem. First, let us find the total per row and per column.
(see attached pic)
P(Grade 10 | opposed) with P(opposed | Grade 10)
P(Grade 10 | opposed) = Number in Grade 10 who are opposed
/ Total number of Opposed (column)
P(Grade 10 | opposed) = 13 / 41 = 0.3171
P(opposed | Grade 10) = Number in Grade 10 who are opposed
/ Total number in Grade 10 (row)
P(opposed | Grade 10) = 13 / 32 = 0.4063
Therefore:
P(Grade 10 | opposed) IS NOT EQUAL P(opposed | Grade 10),
hence they are dependent events.
Answer:
P(Grade 10 | opposed) < P(opposed | Grade 10)
The answer is b. The others don’t make sense
x=-1/2

Answer:
24°:48°:108°
Step-by-step explanation:
Since the sum of angles in a triangle is 180°, we can do 180÷15 to find the degree for 1 in the ratio. 180÷15 = 12.
12°×2 = 24°
12°×4 = 48°
12°×9 = 108°
The ratio is 24°:48°:108°
Answer:
No
Step-by-step explanation:
A little trick to easily see if things are divisible by 3 is to add the 2 numbers together.
For example with 71 if you add 7+1 you get 8. 8 is not divisible by 3.
However if you were looking at 81 you add 8+1 to get 9. 3×3=9 so 81 is divisible by 3.
By putting that into a calculator you can see that 81/3=27 and 71/3=23.6666...
Hope that helped!
