3/5 + 2 3/4
= 3/5 + 11/4
= 12/20 + 55/20
= 67/20
= 3 7/20
This answer uses NMF, which can be found out about in my profile:
We know that the length has to equal the width and height. This means that the amount of cubes used in total has to be the cube (power of 3) of the side length.
The answer is
floor#({3}√{x}) = {3}√{x}
where x is your possible answers and the statement is true.
If we do x = 81, then we can do
{3}√{81} ≈ 4.33
floor#(4.33) ≠ 4.33
therefore the answer is not 81
x = 243:
{3}√{243} ≈ 6.24
floor#(6.24) ≠ 6.24
x = 486:
{3}√{486} ≈7.86
floor#(7.86) ≠ 7.86
x = 729:
{3}√{729} = 9
floor#(9) = 9
Because they are equal, the number of cubes used is 729.
Answer:
2(2x-1)
Step-by-step explanation:
Answer:
1.4% of connectors fail during the warranty period.
Step-by-step explanation:
We have these following probabilities:
A 90% probability that a connector is kept dry.
A 10% probability that a connectors is wet.
If a connector is dry, an 1% probability of failling.
If a connector is wet, a 5% probability of failling.
What proportion of connectors fail during the warranty period?
This is 1% of 90% and 5% of 10%. So
1.4% of connectors fail during the warranty period.
