Which expression is equivalent to 10^2•10^4?A) 10^2

B) 10^4

C) 10^6

D) 100^6

Step-by-step explanation: When multiplying same-numbers with exponents, you only need to add the exponents. In this case, that’s 2 and 4.

Hey there!

ORIGINAL EQUATION:
10^2 * 10^4

~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~
10^2

= 10 * 10

= 100

WORKING OUT THE EQUATION:

10^4

= 10 * 10 * 10 * 10

= 100 * 100

= 10,000

PROCESS OF ELIMINATION:
Option A.
10^2

= 10 * 10

= 100

Option A. is incorrect because it’s too small!
—————————————————————

Option B.
10^4

= 10 * 10 * 10 * 10

= 100 * 100

= 10,000

Option B. is also incorrect because it is too small just like Option A.
—————————————————————

Option C.
10^6

= 10 * 10 * 10 * 10 * 10 * 10

= 100 * 100 * 100

= 10,000 * 100
= 1,000,000

—————————————————————

Option D.

100^6

= 100 * 100 * 100 * 100 * 100 * 100

= 10,000 * 10,000 * 10,000

= 100,000,000 * 10,000

= 1,000,000,000,000
Optipn D. is incorrect is also incorrect because it too big.

What is true of the data in the dot plot? Check all that apply.Number of Minutes Shelly Spent Waiting for the Bus Each Morning
A dot plot going from 10 to 15. 10 has 2 dots, 11 has 4 dots, 12 has 0 dots, 13 has 3 dots, 14 has 6 dots, 15 has 1 dot.
The center is 13.
The center is 14.
The peak is at 14.
It has two clusters.
It is skewed left.
The spread is from 13 to 15.
The person waited for the bus 16 times.

The center is closer to 14, the peak is at 14, the plot is skewed to the left, the spread is from 10 to 15, and the person waited for the bus 16 times which indicate the number of dots or data entries on the dot plot.

### Explanation:

From the provided description, we can make several determinations about the dot plot. The center would represent the typical or median value. Because the data is divided in such a way that 11 is to the left and 14, we can observe that the center is somewhat closer to 14 than it is to 13. Therefore, the accurate statement would be that 'The center is 14' rather than 'The center is 13.'

The peak of the dot plot is the value with the greatest frequency, which is the number that has most dots associated with it. As mentioned in the question, 14 has 6 dots, which is the highest count, so it's accurate to say that 'The peak is at 14.'

The plot doesn’t have two even groups of data, hence the statement 'It has two clusters' is incorrect. Also, since the majority of the data points or dots are towards the right-hand side, it's more accurate to say that this plot is skewed left. The spread of the data is actually from 10 to 15, not from 13 to 15. Lastly, by counting the total number of dots which represent the number of days, it is accurate to say 'The person waited for the bus 16 times'.

Enter the value of n so the expression (-y + 5.3) + (7.2y-9) is equivalent to 6.2y + n.Please explain what and how you did it. I've seen other answers for the same question, but they do not make sense.

If you would like to find the value of n, you can calculate this using the following steps:

(- y + 5.3) + (7.2 * y - 9) = - y + 5.3 + 7.2 * y - 9 = - y + 7.2 * y + 5.3 - 9 = 6.2 * y - 3.7

6.2 * y - 3.7 = 6.2 * y + n
n = - 3.7

The correct result would be - 3.7.
