Answer:

n=_23

Step-by-step explanation:

12/n-1=10/n+3

12(n+3)=-10(n-1)

12+36=-10n-10

12n-10n=-10-36

2n=46

n=46/2

n=-23

3) A cable company had 595 subscribers. The ratio of regular subscribers to premium
IgorLugansk [536]

Answer:

280

Step-by-step explanation:

We know that there are at least 8 regular subscribers and there are at least 9 premium subscribers. And we know it's in that ratio. So the best way to start this is to divide 595 by 8+9 to get the single unit amount of both subscribers:

595/17 = 35

So one unit of anything is at least 35. Now, since we're looking for regular subscribers, we'll multiply this value by 8:

35*8 = 280

So 280 is our answer!

Of 70 tosses of a dime, 55 results are heads. Find the empirical probability of tossing heads with this coin. ______ Is this a f
Aleksandr-060686 [28]
The empirical, or experimental, probability of an event is the number of times the event occurred over the number of times the experiment was conducted.  In this case it would be 55/70 = 11/14, as there were 55 heads flipped out of a total of 70 coin flips.
Mathematically speaking, no, this is not a fair coin.  To be fair, both events would have to have the same chance of happening.  Since the probability of heads was 55/70, that leaves 15/70 for tails.  The chances are not equal, so not fair.

Oksanka [162]
I dont know what benchmark means but <em />I hope this works<em>. </em>First, multiply 7 10ths by the denominator of 12. 7/10 *12= 84/120.
Then multiply 5 12ths by  10. 5/12 *10=50/120. So, 7/10 > 5/12

I spent 80% of my money and had $12 left. How much money did I have to start ?
xeze [42]
If you spent 80% that means you have 20% left, we'll use B as variable

20% x B = 12
0.20/0.20 x B = 12/0.20
B = 60
