1, 2, 3, 4, 5, 6, 7, 8, 9, 10<br>Mean:<br>Median:<br>Mode:<br>Range:​
Papessa [141]

Answer:

mean= 5.5

median=5.5

No mode.

range=9

Step-by-step explanation:

Recall that the mean of a data set is the sum of its terms divided by the number of terms.

1+2+3+4+5+6+7+8+9+10=55

55/10=5.5

Recall that the median of a data set is the value at the middle (the median) of the data set. In order to find the median, the data set must be arranged from lowest to highest. Once it is, we cross out one at the end, one at the beginning, one at the end, one at the beginning, and so on until we find the middle value.

Since there are an even number of terms, the median will be between the two middle values. Take the average of the two:

median=5+6 divided by 2=5.5

The mode of a data set is the element that appears most frequently. Since each element in this data set is unique and only appears one time, there is no mode.

Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is

10-1=9

READ THE PICS AND JUST SAY ABCD THANKS
Semenov [28]
(2g⁵)³ / (4h²)³
Since power ³ is outside parenthesis, you should put the power to each expression inside parenthesis as below
2³(g⁵)³ / 4³(h²)³
in the multiplication of exponents, you add the indices
8(g⁵⁺³) / 64(h²⁺³)
8g⁸ / 64h⁵
it simplifies into 
1g⁸ / 8h⁵
Your answer is D) g⁸ / 8h⁵
