Answer:
4) 7.9%
Step-by-step explanation:
Given:
% of milk chocolate = 70%
% of white chocolate = 30%
Total number of chocolate = 20
Number of milk chocolate:
Number of white chocolate:
From the calculations, we now know there are 14 milk chocolates and 6 white chocolates.
2 white chocolates are picked at random without replacement.
Probability first chocolate picked was white:
Probability second chocolate picked was white:
To find probability that both of them are white chocolates, multiply probability of the first and second.
0.3 * 0.2632 = 0.07896
≈ 0.079
Convert to percentage by multiplying by 100.
0.079 * 100 = 7.9%
The probability that they are both
white chocolate is 7.9%
2700 (1-4%) 5. population by 2020 would be 2201
Answer:
Step-by-step explanation:
We need to first find the radius of the sphere.
The surface area of a sphere is given as:
where r is the radius
Therefore:
The radius of the sphere is 4 cm.
The volume of a sphere is given as:
Therefore, the volume of the sphere of radius 4 cm is;
The volume of the sphere is
First, multiply the 1,500 by 4.3% to come up with $64.50 every three months (the question says compounded quarterly).
$64.50 x 4(quarters in a year) = $258.00 per year
$258.00 x 6 years = $1,548.00
$1,500.00 + $1,548.00 = $3,048.00 balance after six years
