Multiples of 5 are A{5,10}
multiples of 2 are B{2,4,6,8,10,12,14}
Multiples of 2 OR 5 are {2,4,5,6,8,10,12,14} for 8 possible outcomes.
Therefore the probability of spinning a multiple of 2 or 5
P(2x or 5x)=8/14 = 4/7
Answer:
7 hr * 12 days = 84 hours
10*84 = 840 man-hrs to build the wall
----
14 men * 8 hr = 112 man-hrs/day
840/112 = 7.5 days
Step-by-step explanation:
Each face of the cube has an area of 4cm^2 (2*2 = 4). A cube has six faces so the total surface area is 24cm^2 (4cm^2*6).
A) 31.110
B) 0.110
When rounding to three decimal places, you consider if the number to the right of the third decimal place is less than or greater than 5. If it's less than 5, then the digit in the third decimal place stays the same. If it is greater than or equal to 5, then you round the digit in the third decimal place up by one.
