Answer:
c. 3/8
Step-by-step explanation:
For each toss, there is a 50/50 probability that it lands on heads or tails. Let T be a tails and H be a heads, the sample space of this experiment is:
S={HHH, HHT ,HTT ,HTH, TTT, TTH, THH, THT}
The experiment has 8 possible outcomes. Only three of those outcomes have exaclty two heads (HHT, HTH, THH). Therefore, the probability of getting exactly two heads is 3/8.

Area of a triangle, any triangle, is defined as base times height divided by two.
Why?
Think about if this right triangle was a rectangle. You'd multiply the four times the two for the area, right? Now we first have to realize that this triangle is half of a rectangle, and <em>that's why</em> we divide by two.
Therefore, we have:
A =
A = 2(4)/2
A = 8/2
A = 4 units squared.
Hope this helps!
For the 1st hour the cost is $50 whatever is the duration (providing it's 1 hour max.
From one hour and onward the cost becomes an additional $25 per quater of an hour.
If y is the cost and x the number of hours, then the equation becomes :
y =50 + 0.25.x or y =1/4x + 50
Answer:
For real
Step-by-step explanation:
Here are the following factors for 51 and 100:
51= 1, 3, 17, 51
100=1, 2, 4, 5, 10, 20, 25, 50, 100
Since none of the numbers that go into 51 go into 100
(1 doesn't count) 51/100 is the correct answer, and cannot be put into lower terms.
