Answer:
99.8 %
Step-by-step explanation:
μ = 75 and σ = 5
The information about 68-95-99.7 rule is:
μ ± 0,5σ 68.3 % of all values will be in the interval
[ μ - 0,5σ ; μ + 0,5σ ] [ 72.5 : 77,5 ]
μ ± 1σ 95 % of all values will be in the interval
[ μ - 1σ ; μ + 1σ ] [ 70 : 80 ]
And:
μ ± 1,5σ 99.7 % of all values will be in the interval
[ μ - 1.5σ ; μ + 1.5σ ] [ 67,5 : 82,5 ]
And still 85 is bigger than 82,5 we can conclude that approximately 99.8 % will be smaller than 85 and then "the relative frecuency of rates less than 85 is very high 99.8 %
The answer is 12.
First you multiply 8 by 5, which gives you 40. Then, you divide 40 by 2, which gives you 20.
Finally, you subtract 20 by 8 because 5 + 3 = 8.

Step-by-step explanation:
To find the capacity of a tank: multiply the length by the width to get the area. Then multiply the area by height to get volume. Finally, multiply the volume by 7.48 gallons per cubic foot to get capacity.
