Answer:
7536 
Step-by-step explanation:
Given that:
Rate of decreasing of radius = 12 km/sec
Height of cylinder is fixed at = 2.5 km
Radius of cylinder = 40 km
To find:
The rate of change of Volume of the cylinder?
Solution:
First of all, let us have a look at the formula for volume of a cylinder.

Where
is the radius and
is the height of cylinder.
As per question statement:
= 40 km (variable)
= 2.5 (constant)

As
are constant:

Answer:
positive 11x+ positive 14 to the right is greater than negative 8 to the left

Answer:
The value of the test statistic z for this hypothesis test is -2.79
Step-by-step explanation:
Consider the provided information.
To calculate the test statistic use the formula:

Where, z is Test statistics, n is Sample size, p₀ = Null hypothesized value and
= Observed proportion.
p₀ = 0.50
Thus 1-p₀= 0.50
42% responded that if they had a cell phone, thus 
The sample size is 305.
Substitute the respective values in the above formula.



Hence, the value of the test statistic z for this hypothesis test is -2.79
A fraction actually represents a division problem that can return a decimal real number with which you can solve some problems. ie:4/3 = 4÷3 = 1.333
a. 6×1.25=x 6×1.333=x 6×1.5=x 6×1.75=x 6×2=x make sense?
b. 6×.666=x
c. by definition a cube has equal length sides in all 3 dimensions.
