Answer: 5n-6=39;n=9
Step-by-step explanation:
The product of: indicates multiplication
A number: indicates you need a variable (n)
And five: indicates what your multiplying (5)
Decreased by six: indicate your subtracting 6
Is thirty nine: indicates your answer is 39
Now solve using inverse operations
5n-6=39
<u> +6 +6</u>
<u>5n</u>=<u>45</u>
5 5
n=9

Theoretical probability is what, theoretically, the probability <em>should </em>be, regardless of data. Because there are only two options, the probability for getting heads on each toss should be 50%. For the total thirty tosses, theoretically, the coin <em>should</em> land on heads fifteen times, or five per trial, which is determined solely on the number of options.
Experimental probability is what the probability was based on the given data. In the first trial, head was scored 5 times, or 5/10, or 50%. This was repeated in the second and third trials. So, based purely <em>on the data,</em> the probability of the coin landing on heads was also 50%.
I hope this helps!

Answer:
Step-by-step explanation:
m = number of minutes
$ 8 monthly fee + 19 cents per minute
the expression for this is : 8 + 0.19m
$ 25 monthly fee and 14 cents per minute
the expression for this is : 25 + 0.14m
to find out when they will be equal, just set them equal to each other and solve for m, the number of minutes
8 + 0.19m = 25 + 0.14m .....subtract 0.14m from both sides
8 + 0.19m - 0.14m = 25......subtract 8 from both sides
0.19m - 0.14m = 25 - 8.....combine like terms
0.05m = 17...divide both sides by 0.05
m = 17 / 0.05
m = 340 <==== they are both the same at 340 minutes
