Answer:
7/10
Step-by-step explanation:
7/8 = .875
10/12 = .833
12/14 = .857
7/10 = .7
1/2 - .5
Probability=(number of specific outcomes)/(total number of possible outcomes)
P(!Z)=25/26 as a fraction exact
P(!Z)≈96.2% (approximation to nearest tenth of a percent)
This is a hexagonal prism: Volume = Area of Base (hexagon) x Height:
There are 6 equal equilateral triangles in a hexagone.
The apothem (or altitude of each triangle) = side x (√3)/2 =12(√3)/2 = 6√3
Area of ONE equilateral triangle = (side x altitude)/2:
Area of ONE equilateral triangle = (12 x 6√3)/2 = 36√3 ft²
Area of the SIX equilateral triangles = 36√3 x 6 = 216√3 ft²
VOLUME = BASE X HEIGHT = 216√3 x 15 = 3240√3 ft³
OR VOLUME = 5612 ft³
20 mails in 1/4 day (0.25 day)
-> 1 day = 20/0.25 = 80 emails
