Answer:
<h2>The first option is correct 1675.5 cm^3</h2>
Step-by-step explanation:
Step one:
we are given the radius as
r=2cm, and the number of spheres is 50 in numbers
let us find the volume of one sphere and multiply the area by 50 to get the volume of the 50 spheres
Step two:
The volume of one sphere is 33.5in^3
Hence the volume of the 50 spheres will be
=33.5*50
=1675.7cm^3 approx.
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 %
It's the factor theorem.
P(-4)
Equal to 0
Answer:
Step-by-step explanation:
Answer: A. 1/4n - 2 = 10
Step-by-step explanation:
1/4n = One-forth of a number
-2 = Two less than
= 10 = is 10
