-52 is the answer because you have to isolate 1/3x by adding 2/3 to -18 then you have to multiply -18/1 by 3 so you can have a common denominator. After, you should have -54/3 plus 2/3 you subtract the two and get -52/3. You then have 1/3x equals -52/3. You divide 1/3x by -52/3 which means you have to multiply by the reciprocal of 1/3x which is 3/1x. You multiply that by -52/3. The threes cancel out and you're left with x = -52.

Answer:
0.513 = 51.3% probability of being a female.
Step-by-step explanation:
We are given the following formula:

In which:
Event F: Female
Event C: Red-green color blindness.
Probability of a Female
We have to find P(F), which is given by:

We are given by:

So

0.513 = 51.3% probability of being a female.
Answer:
C is the most suspicious set.
Step-by-step explanation:
We would expect that B wins 4/5 * 30 = 24 games.
In set A, B wins 23 games.
In B, B wins 24 games.
In C, B wins 15 games.
In D, B wins 25 games.
So result C is very suspicious.
Answer:
p= 6q+7
-7. -7
p-7 =6q
/6. /6
p-7/6
Step-by-step explanation:
if you want to make a specific term the subject, you need to isolate it on one side of the equation. You do this by 'getting rid' of anything on the term's side of the equation, starting with whatever's furthest from the term. (think BEMDAS but backwards)
p = 6q + 7
(take 7 from both sides to get rid of +7 on q's side)
p - 7 = 6q + 7 - 7
p - 7 = 6q(divide both sides by 6 to get rid of 6 on q's side)
=
q=
