Answer:
4x-1
Step-by-step explanation:
The working is shown in the above photo
Consider this option (2 ways for this):
1. Probability=1-[probability_all_boys].
for [probability_all_boys]=1/[all_possible_combinations];
for [all_combinations]=2³=8. It means that
Probability=1-(1/8)=7/8=0.875.
2. Probability=[needed_cases]\[all_possible_cases];
all possible combinations are:
bbb;ggg;bgg;bgb;bbg;gbg;gbb;ggb; - (where 'g' - girl, 'b' - boy) total 8.
needed cases: ggg;bgg;bgb;bbg;gbg;gbb;ggb, - total 7.
Probability=7/8=0.875
It is 18 because it is a square so all the sides have to be the same so that would make it 18
Answer: The larger cylinder would 90cm^3
Step-by-step explanation:
If both have a base area of 10cm^3
Try to work the problem normally and just add the cube as your unit. 6cm is your height for the small cylinder so add 3 meaning the large will be 9cm tall. Then multiply, 10cm by 9cm = 90cm^3.
The formal is V=pi r^2 h
Hopefully this helps.
