Answer: 1.) x - 2y = 4 , add 2y to both sides. ---> answer is, X = 2y + 4
2.) 2x - 6y = 8, Add 6y to both sides, then divide both sides by 2. --> answer is, X = 3y + 4
Answer:
blue one (c), not independent because P(A|B) ≠ P(A)
Step-by-step explanation:
Two events are independent of each other if you can mulitply them to get their intersection
To find the conditonal probability of two independent events you can use the following idea/formula
P(A|B)= (P(A)*P(B))/P(B) which simplifies to P(A) (so the probability of A given B when A and B are independent of each other is just the probability of A)
Now with the numbers we're given let's find P(A|B)
.24/.9= .26666666666667
Because this is not equal to .3 (or P(A)) the answer must be the blue one
The equation is 10 + 2x= 56; 56 - 10= 46; 46 ÷ 2= 23,
The answer is 23 people.
Hope this helps :)
