The average age of residents in a large residential retirement community is 69 years with standard deviation 5.8 years. A simple

frosja888 [35]

Answer:

a. of the central limit theorem.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a large sample size, larger than 30, can be approximated to a normal distribution with mean $\mu$ and standard deviation $\frac{\sigma}{\sqrt{n}}$

In this problem, the sample size is 100, so it is sufficiently large to use the Central Limit Theorem. The mean of the sample in 69 and the standard deviation of the sample is 0.58.

So the correct answer is:

a. of the central limit theorem.

The Janie Gioffre Drapery Company makes three types of draperies at two different locations. At location I, it can make 10 pairs

Tcecarenko [31]

Answer:

30 days at location I
35 days at location II

Step-by-step explanation:

Let x and y represent days of operation of Location I and Location II, respectively. Then we want to minimize the objective function ...

650x +750y

subject to the constraints on drape production:

10x +20y ≥ 1000 . . . . . order for deluxe drapes

20x +50y ≥ 2100 . . . . . order for better drapes

13x +6y ≥ 600 . . . . . . . order for standard drapes

__

I find a graphical solution works well for this. The vertices of the feasible solution space are (x, y) = (0, 100), (30, 35), (80, 10), (105, 0). The vertex at which the cost is minimized is

(x, y) = (30, 35)

This schedule will produce exactly the required numbers of deluxe and standard drapes, and 2350 pairs of better drapes, 250 more than required.

_____

In the attached graph, we have reversed the inequalities so that the solution space (feasible region) is white, not triple-shaded. Minimizing the objective function means choosing the vertex of the feasible region so that the line representing the objective function is as close to the origin as possible.

Please help fast im taking a quiz.

olga2289 [7]

Answer:

1.30

Step-by-step explanation:

3+5x=7

Subtract 3 on both sides, 3 will cancel out on the left side and will subtract by 7 making it 4

5x=4

Then divide by 5 on both sides to isolate the x.

5/4=1.25

1.25 rounds to 1.3

Hope this helps C:

Lines can be used to approximate a wide variety of functions; often a function can be described using many lines. If a stock pri

4vir4ik [10]

We are given: Price of stock on 1st January = $10.

And price of stock on 31st january = $12.

Let us represent Day number and Price by coordinate (x,y).

Therefore, coordinates for January month can be written as (1,10) and (31,12).

Price of stock on 1st February = $10.

And price of stock on 28th February = $9.

Let us represent Day number and Price by coordinate (x,y).

Therefore, coordinates for February month can be written as (1,12) and (28,9).

Now, we can plot those two different pairs of coordinates for January and February on the graph.

From the graph, we can see that slope of red line is greater and it is positive and slope of green line is negative(because price decreasing).

Therefore, the price change from $10 to $9 is not a straight line.

Therefore, we can say from January 1 to January 31 the rate is inceasing so the slope is positive then after 1 February the rate started decreasing so the slope became negative.
