Answer:

1,2,4,6,8

And the median can be calculated from the value in the position 3th and we got 4

Median =4

And now using the correct dataset is: 1, 18, 6, 2, 4. And if we order the dataset we got:

1,2,4,6,18

And the median for this case again would be the value in the 3th position and we got:

Median =4

So then we can conclude that the median is unaffected by the change of 18 instead of 8

Step-by-step explanation:

For this case we have the original dataset given:

1, 8, 6, 2, 4

And the median for this dataset can be calculated with the following dataset ordered:

1,2,4,6,8

And the median can be calculated from the value in the position 3th and we got 4

Median =4

And now using the correct dataset is: 1, 18, 6, 2, 4. And if we order the dataset we got:

1,2,4,6,18

And the median for this case again would be the value in the 3th position and we got:

Median =4

So then we can conclude that the median is unaffected by the change of 18 instead of 8

kenny6666 [7]

Answer:

2 hours, 26 minutes

Step-by-step explanation:

2 boxes of 21 parts = 42 total parts

3 minutes per part = 42 x 3 = 126 minutes

10 minutes per box to package = 10 x 2 = 20 minutes

126 + 20 = 146 minutes

2 hours = 120 minutes

146 - 120 = 26

Carl earns $5.25 per hour walking his neighbors dogs. He walks them 2/6 of an hour in the morning and 1/2 of an hour in the afte
DIA [1.3K]
2/6 = 1/3 = 20 minutes
1/2 = 30 minutes
20 + 30 = 50 minutes

50 minutes x 7 = 350 minutes = 5 hours and 50 minutes
5 x $5.25 = $26.25
50 minutes = 5/6
5/6 of $5.25 = 4.375

Add $26.25 to the total for 50 minutes to get your answer. :)

Intr un album numarul de fotografii s a micsorat cu 50%. Cu cat trebuie sa se mareasca pentru a reveni la numarul initial? Raspu
hodyreva [135]

Răspuns:

100%

Explicație pas cu pas:

Permiteți numărul inițial de fotografii = x

x - 50% din x = x - 0,5x = 0,5x

0,5x + câte% din 0,5x = x

x - 0,5x = y% de 0,5x

0,5x / 0,5x = 1

Prin urmare,

100% = 1

Prin urmare, x trebuie mărit cu 100% pentru a reveni la numărul original.
