2
n
−
7
=
19
Explanation:
Well first we should look at the part that says "twice a number"
This number can be anything so let's assign a variable to it
Let
n
=
a number
And we also see at the end "twice a number equals 19"
So we get
2
n
=
19
Then we see that "Seven less than"
2
n
all equals
19
So we get
2
n
−
7
=
19
Now if you would want to solve this equation you first add
7
to both sides and we get
2
n
=
26
Then we divide both side by
2
So
n
=
13

A theater has 10 rows of seats with
Digiron [165]

Answer:

52 Empty Seats

Step-by-step explanation:

10 rows of 8 seats would be 10 x 8, which you would get 80. Then you would subtract the amount of people seated in those seats. which is 28

10 x 8 = 80

80 - 28 = 52

There are 52 empty seats left.

Answer:
The experimental probability is 1/6, and the theoretical probability is 1/4. The theoretical probability is greater than the experimental probability in this trial.
-------------------
Explanation:

Theoretical probability is the mathematically calculated probability of the circumstances occurring. 

There is a 1/2 chance of rolling an even number, and a 1/2 chance of flipping a coin on heads.

Since the question asks for the possibility of both happening, multiply those together to find the probability:

\frac{1}{2} *   \frac{1}{2} =  \frac{1}{4}

The theoretical probability of rolling an even number and then flipping a head is 1/4.

Now we'll focus on Taka's trials.

Experimental probability is the probability that is taken from results of a trial.

Take the results, and see if they match the criteria of rolling an even number and flipping heads.

The results that are bolded fit the criteria:
<span>1 H, 4 T, 1 H, 5 T, 2 H, 3 T, 6 T, 2 H, 3 T, 5 T, 3 H, 4 T
</span>
Taka managed to roll and flip the coin to fit the criteria 2 times out of 12. Converted into a fraction, it is 2/12. Simplified, the experimental probability is 1/6.
