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.
Answer:
Shania has read the most pages.
Step-by-step explanation:
Following the formula y = mx + b.
Kevin already read 45 pages.
y = mx + 45
He reads 20 pages per hour, since it has per hour, we put it has "m"
y = 20x + 45
Shania already read 5 pages
y = mx + 5
Shania reads 25 pages per hour
y = 25x + 5
We need to find out how many pages they read after 20 hours, plug 20 into x.
Kevin
20(20) + 45 =
400 + 45 =
445
Shania
25(20) + 5 =
500 + 5 =
505
Shania read 60 more pages than Kevin.
To do this you would have to use the Pythagorean Theorem, which is
a^2+b^2=c^2
The longest side would be your c^2, the smallest side is your a^2, and the remaining side is your b^2
The 7 is your a^2, 24 is b^2, and x is c^2
Plug in the numbers into your equation
7^2+24^2=x^2
Then, just solve:
49+576=x^2
625=x^2
To get rid of the ^2 in x^2, you would have to square root both sides to get x by itself
25=x
So x is equal to 25
Hope this helps!
