P(Grade 9 | opposed)
The probability of Grade 9, given opposed, is the portion of opposed students that are in grade 9.
Total number opposed: 33
Number opposed in Grade 9: 2
P(Grade 9 | opposed) = 2 / 33 = 0.06
P(opposed | Grade 9)
Total Number Grade 9: 14
Number opposed in Grade 9: 2
P(opposed | Grade 9) = 2 / 14 = 0.14
Answer:
76
Step-by-step explanation:
When you solve the equation you will do parentheses first (10+2) which equals 12 then you carry everything down. Next you will multiply 3 x 12 to get 36 then you carry the 20 and 2 down. Next you will multiply 20 by 2 to get 40 and then add 36 + 40 to get 76.
3(10+2) +20 x 2
3(12) +20 x 2
36 + 20 x 2
36 + 40
76 : answer
Answer:
1.25 kilometers
Step-by-step explanation:
distance divided by time
so
7.5/6= 1.25
Answer:
x=3
Step-by-step explanation:
Isolate x.
Divide both sides by four
Take 
of both sides. In other words, what power must you raise 5 to in order to get 125? (

x=3
Answer:
x = 
, y = 
<u>Explanation</u>:
2x - y= 2
3y= 4x - 5
<u>Make y the subject:</u>
2x - y= 2
-y = 2 - 2x
y = 2x - 2 <em>.........equation 1 </em>
3y= 4x - 5
y = (4x - 5)/3<em> ........equation 2</em>
From equation 1 and 2 solve them simultaneously:
→ (4x - 5)/3 = 2x - 2
→ 4x - 5= 3(2x - 2)
→ 4x - 5 = 6x - 6
→ 6x - 4x = -5 + 6
→ 2x = 1
→ x = 1/2
- if x is 1/2, then y: 2x - 2
→ 2(1/2)-2
→ -1
