Answer:

E. 3x + 6 = 2x + 9

Step-by-step explanation:

The total number of charms that Lydia has in term of x

6 + 3x

The total number of charms that Claudia has in term of x

9 + 2x

Since they have the same number of charms, we can set these 2 equations above equals to each other

6 + 3x = 9 + 2x

x = 9-6 = 3

So E is the correct answer

4, 6, 2, 8, 4, 4, 2, 10<br> Mean:<br> Median:<br> Mode:
Troyanec [42]

Answer:

Mean: 5

Median: 4

Mode: 4

Step-by-step explanation:

Mean:

1. To find the mean given a data set, you have to add up all the data points and then divide them by the number of data points there is.

  • \frac{4+6+2+8+4+4+2+10}{8}
  • \frac{40}{8}
  • 5

Therefore, the mean is 5.

Median:

1. To find the median given a data set, we first have to arrange the data points in order.

  • 2, 2, 4, 4, 4, 6, 8, 10

2. Next, we have to find which data point is in the middle. In this case, the middle number is 4.

Therefore, the median is 4.

Mode:

1. To find the mode given a data set, you just have to find which data point is the most frequent.

  • 1 data point of  2
  • 3 data points of 4
  • 1 data point of 6
  • 1 data point of 8
  • 1 data point of 10

Because the most frequent value is 4, the mode is 4.
