Answer:
Step-by-step explanation:
Given that demand function for a product is modeled by
where p = price in dollars and
x= units demanded
a) When x=1000, we substitute 1000 for x
i.e. price is 1092.32 dollars
b) X = 1500
i.e. price is 692.28 dollars
c) When x increases without bound exponent with negative power becomes 0 making price = 10000(1-3/3) =0
Answer:
(x−1)(2x3+2x2+2x−1)
combine like terms, then factor
Step 1 involves you listing out all the ways to multiply to 56, and then adding up those factors. For instance, the first row has 1 and 56 which add to 57 in the third column. The second row has -1 + (-56) = -57. The third row has 2+28 = 30. And so on. The idea is to fill out the table completely with the other ways to have factors of 56 added up. The table is shown in the attached image below.
------------------
Step 2 then uses the table to figure out which pair of factors (of 56) add to -15. This would be -7 and -8. In other words,
-7 plus -8 = -15
-7 times -8 = 56
We have found the right pair of numbers. In the table I have provided, this is shown as the highlighted yellow row.
------------------
Step 3 is then using those pair of numbers found in step 2 to set up the factorization. We would say that x^2-15x+56 factors to (x-7)(x-8). This is the same as (x-8)(x-7) as we can multiply two numbers in any order we want.
Answer:
The answer is Option A: "0.2% is a parameter and 11 is a statistic".
Step-by-step explanation:
The main difference between a statistic and a parameter is that a statistic describes a characteristic from a sample and a parameter describes a characteristic of the entire population.
In this case, 11 is the result of the positive salmonella eggs taken out of a sample of 200 eggs. It is a statistic.
Also, we know that of all eggs shipped (the population), 0.2% has salmonella. This 0.2% is a parameter.
The answer is Option A: "0.2% is a parameter and 11 is a statistic".
Answer:
5*8+14=54
Step-by-step explanation:
5*x+14= 54
so
54-14= 40
40/5=8
so x=8
