The measure of the variation of the data is 2.2 hours.

How to calculate the mean average deviation?

The dot plot shows the weekly biking times (in hours). To describe the center, the most appropriate measure is the median, since the distribution appears to be roughly symmetric.

To find the median, we arrange the data in order from smallest to largest:

2, 4, 4, 5, 6, 7, 8, 8, 9, 10

There are 10 data points, so the median is the average of the fifth and sixth values:

median = (5 + 6) / 2 = 5.5

So, the measure of the center of the data is 5.5 hours.

To describe the variation, the most appropriate measure is the mean absolute deviation (MAD), which measures the average distance of each data point from the median.

To calculate the MAD, we first find the deviations of each data point from the median:

|2 - 5.5| = 3.5

|4 - 5.5| = 1.5

|5 - 5.5| = 0.5

|6 - 5.5| = 0.5

|7 - 5.5| = 1.5

|8 - 5.5| = 2.5

|9 - 5.5| = 3.5

|10 - 5.5| = 4.5

Next, we find the average of these deviations:

MAD = (3.5 + 1.5 + 1.5 + 0.5 + 0.5 + 1.5 + 2.5 + 2.5 + 3.5 + 4.5) / 10

MAD = 2.2

So, the measure of the variation of the data is 2.2 hours (rounded to the nearest tenth).

Step-by-step explanation:

possibly Chondro malacia

Damage to the cartilage under the kneecap.

Symptoms may include

Knee pain

Cracking joints

Swelling of the knee

Please go to your doctor...ik it hard with cov id and everything

It could be hereditary, or it could just be a weak muscle. I have knee problems. If it’s just your knee cap that is dislocating you can do simple exercises to strengthen the muscle around it to hold it in place. If it’s your actual knee you should get it checked out to see if there is anything else going on. If it continues and there’s nothing “wrong” they’ll have you do physical therapy. When this dislocation happens, keep your knee up above your heart and ice it. After you pop it back on. And take pain relief. Wear a knee brace as well

The mode for Group A is less than the mode for Group B.
The median for Group A is 2.
The median for Group B is 3.

Answers

Answer:

1. The mean for Group A is less than the mean for Group B

2. The median for Group A is less than the median for Group B.

3. The mode for Group A is less than the mode for Group B.

Step-by-step explanation:

1. To find the mean for Group A, you use the formula: Total sum/Total frequency.

To find the total sum, you multiply the frequency(how many times the given number is repeated) with the given numbers.

0 × 0 = 0

1 × 5 = 5

2 × 4 = 8

3 × 1 = 3

4 × 0 = 0

5 × 0 = 0

Total Sum: 5 + 8 + 3 = 16

Total frequency: 5 + 4+ 1 = 10

[tex]\frac{16}{10}[/tex] = 1.6

To find the mean for Group B, you repeat everything above.

0 × 0 = 0

1 × 3 = 3

2 × 2 = 4

3 × 4 = 12

4 × 0 = 0

5 × 1 = 5

Total Sum: 3 + 4 + 12 + 5 = 24

Total frequency: 3 + 2 + 4 + 1 = 10

[tex]\frac{24}{10}[/tex] = 2.4

2. I can't explain it but I'm certain that it is correct.

3. The most repeated number for Group A is 1, it is repeated 5 times, while the most repeated number in Group B is 3, it is repeated 4 times.

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 6 rows of the same length, he
has 7 chairs left over. If he arranges the chairs in 4 rows of that same length, he has 13 left over. How many
chairs does Liam have?

Answers

We will need to have two equations here, having x as the missing length. We know that the chairs are in the same amount on each occasion, so each equation should be equal to the other.

This sets up a problem of:

6x + 7 = 4x + 13

7 and 13 being the leftover chairs and 6 and 4 being the rows. Let’s solve for x.

x = 3

Knowing this, we plug in x for one of the equations

6(3) + 7
18 + 7
25

Liam has 25 chairs.

The expression x ≤ 6 implies that the domain of the x is a set of a real number less than and equal to 6, so all values represented on the number line below and equal to 6 is bold dark.
