Random sampling. its where you pick or make a smaple at random
Answer:
Step-by-step explanation:
1. 96 centimeters squared
2. 300 degrees
3. no, the diagonals of a parallelogram donor intersect at 90 degree ( are not perpendicular) .it is because the adjacent sides of parallelogram are not equal..
4. no
All you have to do is change the whole number to a fraction. Say you have 4 divided by 1/2. All you have to do to make a whole number a fraction is put it over 1. So now you would have 4/1 (4 being the numerator) divided by 1/2. When you divide fractions always remember this; Keep, Switch, Flip. Keep 4/1, Flip the division sign to multiplication, and Flip 1/2 to make it 2/1. Then you multiply the numerators and the denominators. So 4/1 * 2/1 = 8/1. Hope this helped.
Answer:Volume = 108 cm ³
Explanation:For a square pyramid, the volume can be calculated as follows:
Volume =

* area of base * height
Volume =

* side² * height
We have:
side length = 6 cm
height = 9 cm
Therefore:
Volume =

* 36 * 9 = 108 cm ³
Hope this helps :)
Answer:

Computers have been used to check odd numbers up to 10^300 and no odd perfect numbers exist in this range , but that is not a proof that they don't exist.
