Answer:
Step-by-step explanation:
83:17 means that for for every 17 losses there will be 83 wins. Or perhaps looking at a simpler example will help.
Rolling a dice will have the odds of 1/6 to roll any one number. but for a ratio, it is 1:5 in favor of rolling that number. Basically if you roll the dice until you get the number you are looking for, you should roll five of the other numbers and then one of the one you are looking for.
Hopefully you notice in the dice example the sum of the two sides of the ratio add up to the total number of possibilities. This is the detail we are going to use for your question.
Anyway 83:17 will have a total of 83+17 possibilities. And of those 83 are a win. so that's 83/100, which is .87.
I will admit, talking about a slot machine would usually make me assume a low probability, something closer to 0. But reading the question that is what I understand the answer to be.
That means to explain your factors in into detail while also using the factors as exponents, hope that helped
Luckly i still have my notes and the answer was about 3.1%. I hope this helped.
Let´s:
t=time when the both runners coincide.
velocity=distance/time ⇒ distance=velocity x time
distance traveled by Christy=0.12 t
distance traveled by Cindy=0.22 t
Becuse Christy starts the race with an advantage of 1.5 km de distance from Cindy´s position the distance would be : 0.12 t + 1.5
We would have to solve the following equation:
0.12t+1.5=.0.22t
0.22t-0.12t=1.5
0.1t=1.5
t=1.5/0.1
t=15
Answer: In 15 minutes Cindy will catch Christy
Answer: 4 cm and 11 cm.
Step-by-step explanation:
1. You can calculate the perimeter of a parallelogram as following:
Where a+b+c+d are the lenghts of the sides.
By definition the parallelogram has two pairs of parallel sides, therefore:
a=c and b=d
Then, you can calculate the perimeter as following:
2. Let's call the adjacent side , then the other side is 2x+3.
3. Substitute values and solve for x:
4. Then the lenghts of the sides are:
