Well out of 100 jelly beans 24 are black so it would be a 24 out of 100 chance to pick a black jelly bean. But that can be simplified down to a 6 out of 25 chance. So your answer is 6/25. Hope this helped. ;)
The the scale factor is 9
You can do this by dividing the values of the sculpture by the model
For example:
L: 72/8 = 9
W: 54/6 = 9
H: 81/9 = 9
The answer is D. Here's my work:
12x - 6 = 4x
12x-4x = 6
8x = 6
x = 3/4
Difference between the night and and low temperature is 29
