Answer: The man was worse off than in 2005
Step-by-step explanation:
Assume the man's salary in 2005 was $4,500.
In 2006 therefore, his salary goes to:
= 4,500 * (1 + 10%)
= $4,950
In 2007, this drops by 10%:
= 4,950 * ( 1 - 10%)
= $4,455
<em>The man was worse off than in 2005 because the 10% reduction was based on the larger 2006 salary but the 10% increase was based on the smaller 2005 salary. </em>

or
Step-by-step explanation:
step 1
Find the radius of the circular base of the cone
The volume of the cone is equal to
we have
substitute
simplify pi
step 2
Find the volume of the hemisphere
The volume is equal to
we have
----> is the same that the radius of the cone
substitute
step 3
Find the volume of the solid shape
we know that
The volume of the solid shape is equal to the volume of a cone plus the volume of a hemisphere
so
Convert to mixed number
Answer:
difference in the proportion = 0.0452
Step-by-step explanation:
x1 = 27, n1 = 193,
p1 = 27/193
p1 = 0.1399
x2 = 16, n2 = 169,
p2 = 16/169
p2 = 0.0947
a) The best estimate for the difference in the proportion of smokers, using male proportion minus female proportion is 0.0452. Male smokes more than females in given sample.
p1 - p2 = 0.1399 - 0.0947
p1 - p2 = 0.0452
p(10) is the profit, in dollars, from selling 10 books. Replace every copy of x with 10 and simplify
p(x) = 8x-10
p(10) = 8*10-10 .... every x is replaced with 10
p(10) = 80-10
p(10) = 70
So the profit is $70
Factors are the numbers and/or variables between your transactions (division, multiplication, addition, and subtraction signs). So the answer would be x2, 16x, and 64.
