Bezzdna [24]

Answer:

24,800 meters

Step-by-step explanation:

We basically have to convert km to m, or kilometers to meters. For this we need the conversion factor:

1000 meters = 1 kilometers

So change from kilometers to meters, we simply need to multiply by 1000. Thus, we would have:

24.8 km * 1000 = 24,800 meters

Thus,

24.8 km = 24,800 m

The answer is the first one, impossible. This is because it shows that there are red and black cards, but never mentions that there are blue cards at all. This also means there are no blue cards. How could you get a blue card when there are none? It's impossible.

Answer:

The sample standard deviation is 393.99

Step-by-step explanation:

The standard deviation of a sample can be calculated using the following formula:

$s=\sqrt[ ]{\frac{1}{N-1} \sum_{i=1}^{N}(x_{i}-{\displaystyle \textstyle {\bar {x}}}) ^{2} }$

Where:

$s=$ Sample standart deviation

$N=$ Number of observations in the sample

${\displaystyle \textstyle {\bar {x}}}=$ Mean value of the sample

and $\sum_{i=1}^{N}(x_{i}-{\displaystyle \textstyle {\bar {x}}}) ^{2} }$ simbolizes the addition of the square of the difference between each observation and the mean value of the sample.
