Answer:
x = 21
Step-by-step explanation:
The following data were obtained from the question:
Set of data => 7, 15, x–1, x+1, 24, 28
Median = 21
x =?
Median is simply defined as the middle term of a given data arranged either in ascending or descending order.
Next, we shall determine the median of the set of data. This can be obtained as follow:
7, 15, x–1, x+1, 24, 28
Median = [(x–1) + (x+1)]/ 2
Finally, we shall determine the value of x as follow:
Median = [(x-1) + (x+1)]/ 2
Median = 21
21 = [(x-1) + (x+1)]/ 2
21 = [x – 1 + x + 1] /2
21 = [x + x – 1 + 1] /2
21 = 2x / 2
21 = x
Thus, x is 21
****Check****
Median = 21
x = 21
Median = [(x–1) + (x+1)] / 2
21 = [(21 – 1) + (21 + 1)] / 2
21 = [20 + 22] / 2
21 = 42/2
21 = 21
Dwarf crocodile because the dots are more together than with the other. They are showing more consistent results.
Answer:
Volume of square pyramid is 3466.6 cm³
Step-by-step explanation:
We are given:
Base edge of square pyramid = 20 cm
Height of square pyramid = 26 cm
We need to find Volume of square pyramid
The formula used is: 
Where a is base edge and h is height of pyramid
Putting values in formula to find the volume
So, Volume of square pyramid is 3466.6 cm³
9•10^4 / 3•10^3 = 30.
The whale has 30 times the mass of the elephant, or 29 times more. For that reason, it's 29 times heavier than the elephant.
Answer:
b) 4/52
Step-by-step explanation:
Since there are only 4 playing cards in a full deck that are labeled '2', and there are 52 cards in total - then there is a 4 out of 52 chance that a '2' card will be selected!
