Do you mean 27/36? If so, it would be .75
Answer:
0.25. or 1/4
Step-by-step explanation:
The probability that the first coin will be heads is 0.5. The probability that the second coin will be heads is 0.5. So the probability that the first two coins will be heads is 0.5 * 0.5 = 0.25.
Since the third flip can be either heads or tails, this has a probability of 1.0.
So the probability you want is 0.25 * 1.0 = 0.25. (or if you want a fraction it is 1/4)

Answer:
B. 30
Step-by-step explanation:
The given angles are vertical angles because they are opposite angles created by the same two lines. This means that their value is equal. Let's set up an equation.
85 = 3x - 5
We need to solve for x.
First, combine like terms by adding 5 to both sides.
90 = 3x
Now we want to isolate x by dividing both sides by 3.
x = 30
This is your answer.
Let's check our work by plugging x back into our equation.
85 = 3x - 5
85 = 3(30) - 5
85 = 90 - 5
85 = 85
Your answer is correct.
Hope this helps!
Let x = 1st integer.
<span>Equation: </span>
<span>x + x + 1 = 39 </span>
<span>2x = 38 </span>
<span>x = 19 </span>
<span>Answer: 1st integer = 19, 2nd integer = 20, sum = 39.</span>
