Answer:
25
Step-by-step explanation:
If (1/5)^2 equals 1/25, then (1/5)^-2 should be the opposite.
(1/5)^-2 equals 25
Out of 3 coins, if you are given that 1 is on tails, then the most heads you could have is 3 coins - 1 tails = 2 heads.
The probability of getting 3 heads would be 0.

1 Expert Answer
Let x and y be the two numbers. Then by assumptions we have x+y=30 and x-y=20. Hence, y=x-20 and by plugging this into the first equation we obtain x+x-20=30 or 2x=50 or x=25 and y=5
Step-by-step explanation:
So, divide 30 by 2 . That gives you 15 for x, 15 for y. Now, you have difference of six, divide by two, that equals 3.
Answer:
Slope is 3/2
Step-by-step explanation:
<u>Step 1: Solve for y</u>
3x - 2y = 30
3x - 2y - 3x = 30 - 3x
-2y/-2 = (-3x + 30)/-2
y = 3/2x - 15
Answer: Slope is 3/2
