Answer:
The answer is below
Step-by-step explanation:
Given that:
Mean (μ) = 1.93, standard deviation (σ) = 1.08 pounds, sample (n) = 62.
the mean weight of discarded plastic for all household is given by:
The standard deviation of discarded plastic for all household is given by:
The confidence (c) = 90% = 0.9
α = 1 - c = 1 - 0.9 = 0.1
α/2= 0.1/2 = 0.05
The z score of 0.05 corresponds to the z score of 0.45 (0.5 - 0.05) which is 1.645. i.e.
The margin of error (E) =
The confidence interval =
We are 90% confidence that the value is between 1,7044 and 2.1556
The value of x will be equal to x = 2 and x = 7/2.
<h3>What is the cubic equation?</h3>
The polynomial having a degree of three and the maximum power of the variable is three is called the cubic equation.
The solution of the cubic equation will be calculated as follows-
( 2x - 7) ( x² -4x + 4 ) = 0
(2x - 7 ) ( x² - 2x -2x + 4 ) = 0
(2x - 7 ) [ x ( x - 2) - 2 ( x - 2 )]= 0
( 2x - 7 ) ( x - 2 ) ( x - 2 ) = 0
x = 0 and x = 2/7
Therefore the value of x will be equal to x = 2 and x = 7/2.

In order to solve this using V= B(h) (The B is area of the base) you need a radius it doesn't give us that but it does give us the circumference.
C= 3.14(2r)
25.12=2r divide each by 2
12.56=r
now use this in the volume formula:
V= 12.56^2(3.14)(66)
V=32,692.86 cubic inches
