Answer:

Step-by-step explanation:
<-- Given
<-- Distributive Property
<-- Find LCD of x-terms
<-- Combine Like Terms
<-- Add 45/8 to both sides
<-- Simplify Right Side
<-- Subtract 7 on both sides
<-- Divide both sides by 289/60
Total volume is volume of cylinder+volume of cone
Volume of cylinder=pi*r^2*h
V=pi*6^2*14
V=1582.56
Volume of cone=pi*r^2*h/3
V=pi*6^2*6/3
V=226.08
1582.56+226.08=1808.64 or 1808.6 cubic inches
Answer:
-1.683
Step-by-step explanation:
Given :
Group 1 :
x1 = 667 ; n1 = 10 ; s1 = 20
Group 2 :
x2 = 679 ; n2 = 14 ; s2 = 15
The test statistic assuming equal variance :
x1 - x2 / √[Sp² * (1/n1 + 1/n2)]
sp² = [(n1 - 1)*s1² + (n2 - 1)*s2²] ÷ (n1 + n2 - 2)
Sp² = [(10 - 1)*20² + (14 - 1)*15²] = 296.59
Test statistic =
(667 - 679)/ √[296.59 * (1/10 + 1/14)]
-12 / 7.1304978
Test statistic = - 1.682
Answer:
represents the radius (in cm) of a circle whose circumference is 15 cm
if
, then a represents the circumference (in cm) of a circle whose radius is 15cm
Step-by-step explanation:
In a circle the following relationship can be posed:

Let g be a function that determines the radius of the circle from the value of its circumference, so, you have:

Thus,
represents the radius (in cm) of a circle whose circumference is 15 cm. You have to
.
On the other hand, if
, then
represents the circumference (in cm) of a circle whose radius is 15cm. You have to
