The answer is 1/4
Explanation
===============================
The question focuses on "if the student is known to be a boy..." we would obviously know that we would focous on only the total of the boys.
We have the formula for the probability of an event of happening which we would call event A (a boy being left-handed). P(A)= number of favorable outcomes/ total number of possible outcomes. The left-handers would go in the favorable outcomes since we want the probability of a boy being left handed and we would place the total boys in the total number of possible outcomes since all of them are going to be the one to be randomly picked. 50 left-handed/ 200 total boys. We have our fraction that is 50/200 as the probability but we can simplify it! We simplify 50/200 to get 1/4!!! 1/4 is the probability of a boy being picked that is left-handed!
Hope this helps!
The answer is B
The point stated to prove this point is:
Answer:
-2x-14
Step-by-step explanation:
Answer:
-10y - 11x
Step-by-step explanation:
First you need to distribute -7 through the parentheses.
-7y - 14x - 3y + 3x
then you need to collect the like terms (terms with the same variable)
-10y - 11x
In 14 weeks, if you turn both of those into equations you'll get
and
You should be then able to graph this and see that intersects at 14 weeks at 220 dollars
