@mathstudent55 can you help me ?

Probability is all about division. Usually it's the number of "good" outcomes divided by the total number of outcomes. Here, you're asked for the probability that the home team wins. First off, how many "good" outcomes occurred in the sample space? (the games that were studied)

68

That's right. And how many total outcomes were studied?
anonymous
  • anonymous
92 ?
terenzreignz
  • terenzreignz
Okay ^^ So, you have 68 "good" outcomes and a total of 92. Probability is "good" outcomes divided by total outcomes Can you work it out from here?
anonymous
  • anonymous
So it would be 68 divided by 92 ?
terenzreignz
  • terenzreignz
Yup. Use your calculator, your browser, heck, use your mental powers, if that's what you're into :D ^^

I forgot to put my decimal point it was between the 0 and 7
terenzreignz
  • terenzreignz
Okay. Almost there. What is that in percent? And not that I'm doubting your abilities of recollection, but just in case... To convert a decimal such as 0.252913 into percent, simply move the decimal point two places to the right, then affix a % sign. Like this... 0.252913 = 25.2913% ^_^

Okay, I did it and I got 73%
terenzreignz
  • terenzreignz
Nope. Almost, but not quite. You're asked to round it to the nearest whole percent ^^
anonymous
  • anonymous
But the answer choices for this question are : A)68% B)74% C)76% D)92%
terenzreignz
  • terenzreignz
73% isn't even one of the choices ^^ Next best thing?
anonymous
  • anonymous
I think it's B - 74%
terenzreignz
  • terenzreignz
Hehe... I'll cut the suspense. We both know it's 74%
anonymous
  • anonymous
Lol yeah thanks a lot I really appreciated your help :)
terenzreignz
  • terenzreignz
But not because it's the "next best thing" Think about it. Don't you think 73.9 is far closer to 74 than it is to 73? You were doing so well leading up to the answer, but were slightly off in the last step. That's okay, though. It's best you make your mistakes here than on the actual tests... Well done :D

A chemical mixture is being heated. At 10:00, the mixtures temperature was -4°C. If the temperature is increasing at a constant rate of 0.5° per minute, when will it reach 20°C ?

You can just call me Kurt ^^ Anyway, this should be simple enough... It increases by half a degree for every minute, right? By how many degrees do you want it to increase, in total
anonymous
  • anonymous
I'm not sure but the answer choices are A)10:48 B)10:32 C)10:12 D)10:08

Forget those. How many degrees to 20 if you start at -4?
anonymous
  • anonymous
24 or -16
