Answer:
All of the batches of the new blend of concrete made at their plant in a particular week.
Step-by-step explanation:
The population refers to all the subjects or data which which meets the condition or requirement of a certain experiment or research. This means that all the set of similar items or subjects which is of interest in a certain study is the population. In the scenario above, the population will be the set of all the new blend concrete which are made in the plant within a certain week. Thereafter, if a sample is required it will be drawn from these set of data or observation.
Answer:
The Volume is equal to 2x^3-3x^2+2x-3
Step-by-step explanation:
Formula for the volume of a rectangular prism is V=WHL
We know that:
W=x-1
L=x+1
H=2x-3
So, V= (x-1)(x-1)(2x-3)
Simplify
(x^2+1)(2x-3)
2x^3-3x^2+2x-3
Not sure if this is correct but:
Step-by-step explanation: P = 2000
R = 5% = 0.05
n = 4
y = 2000 ( 1 + 
) 
= 2000 ( 1.0125 )
Substitute values in the compound interest formula:
y = P ( 1 + 
)
.
Hope this helps..
Assuming the interest is simple interest, as opposed to compound interest,
Evaluating the given sequence, it is evident that the next number is twice the number prior to it. Thus, the given is a geometric sequence with first term (a1) equal to 1 and common ratio of 2. The geometric series may be calculated by the equation,
Sn = a1 x (1 - r^n) / (1 - r)
where Sn is the sum of n terms in this case, n = 11.
Substituting the known values,
<span> Sn = 1 x (1 - 2^11) / (1 - 2) = 2047
</span>
Thus, S11 is 2047.
