Answer:

(a) C = 9000 + 15N

(b) Cost of 250 widgets is $12750

Step-by-step explanation:

The question has missing details. See attachment for complete question

Solving (a): An expression for total cost.

The expression is generated using:

[tex]Total\ Cost = Fixed\ Cost + Variable\ Cost * Number\ of\ Items[/tex]

From the given parameters:

[tex]Fixed\ Cost = 9000[/tex]

[tex]Variable\ Cost = 15[/tex]

[tex]Number\ of\ Items = N[/tex]

So, the expression becomes:

[tex]C = 9000 + 15 * N[/tex]

[tex]C = 9000 + 15 N[/tex]

Solving (b): Cost of 250 widgets

In this case:

[tex]N =250[/tex]

Substitute 250 for N in [tex]C = 9000 + 15 N[/tex]

[tex]C = 9000 + 15 * 250[/tex]

[tex]C = 9000 + 3750[/tex]

[tex]C = 12750[/tex]

  (b)  540 boxes

Step-by-step explanation:

The 28 foot depth of the trailer will accommodate 18 boxes (leaving 1 ft unfilled).

The 8 1/2 foot width of the trailer will accommodate 5 boxes (leaving 1 ft unfilled).

The 9 1/6 foot height of the trailer will accommodate 6 boxes (leaving 1/6 ft unfilled).

The collection of boxes filling the trailer is 18 deep, 5 wide, and 6 high, for a total of ...

  18 × 5 × 6 = 540 boxes

_____

In each case, the number of boxes that will fit is the dimension divided by the dimension of the box. The result is the integer part of the quotient. For example, ...

  (28 ft)/(3/2 ft/box) = 56/3 box = 18 2/3 box . . . 18 boxes will fit

Answer:

0.281 ; 0.864

Step-by-step explanation:

1.)

p decreases as n increases (n increases, p--> 0)

λ ≥ 0

P(x = x) = (e^-λ * λ^x) ÷ x!

λ for Ford = 1.27

B) zero problems :

P(x = 0) :

(e^-1.27 * 1.27^0) ÷ 0! = 0.281

P(x = 0) = 0.281

Two or fewer problems :

P(x ≤ 2) = p(x = 0) + p(x = 1) + p(x = 2)

P(x ≤ 2) = 0.281 + 0.357 + 0.226

P(x ≤ 2) = 0.864

D.) It allows for early detection and thus adequate curtailment of the problem at an a stage in which it seems easier to curb.

Answer:

a) 0.97605 = 97.605% probability that the process will signal.

b) 0.2076 = 20.76% probability that microaerophiles are present.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

a. What is the probability that the process will signal?

It signals in these following moments:

97.8% of 31%(contains obligate anaerobes).

98.1% of 27%(contains facultative anaerobes).

96.5% of 21%(contains microaerophiles).

99.2% of 12%(contains nanaerobes).

95.9% of 9%(contains aerotolerant). So

[tex]p = 0.978*0.31 + 0.981*0.27 + 0.965*0.21 + 0.992*0.12 + 0.959*0.09 = 0.97605[/tex]

0.97605 = 97.605% probability that the process will signal.

b. If the test signals, what is the probability thatmicroaerophiles are present?

Event A: Test signals

Event B: Contains microaerophiles

0.97605 = 97.605% probability that the process will signal.

This means that [tex]P(A) = 0.97605[/tex]

Intersection of events A and B:

Signals containing microaerophiles, which is 96.5% of 21%. So

[tex]P(A \cap B) = 0.965*0.21 = 0.20265[/tex]

The probability that microaerophiles are present is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.20265}{0.97605} = 0.2076[/tex]

0.2076 = 20.76% probability that microaerophiles are present.

Answer:

x = 86

Step-by-step explanation:

The top right and bottom left angles are part of the reflective property, in turn, the bottom left angle is also 94 degrees; to find the opposite relfective angle set, it would be, in this problem, the top left and bottom right angles; the two top angles make up 180 degrees, so it would be (180-94 = 86) 86 degrees for both the top left and the bottom right angles.

For all Plato users

Approximately 94437.825 tons of LNG will be produced in May, and approximately 104,489 tons will be produced in October month.

Given that, the production of LNG by an energy company increases by 1.7% each month.

Convert the problem to an equation using the percentage formula: P% * X = Y.

Production in April month=91,307+1.7% of 91,307

=91,307+1.7% ×91,307

=92,859.219 tons

Production in May month=92,859.219×(1+1.7%)

=94437.825 tons

Production in June month=94437.825×(1+1.7%)=96,043 tons

Production in July month=96,043×(1+1.7%)=97,676 tons

Production in August month=97,676×(1+1.7%)=99,336.49 tons

Production in September month=99,336.49×(1+1.7%)=1,01,025.21 tons

Production in October month=1,01,025.21×(1+1.7%)=1,04,489 tons

94437.825 tons of LNG will be produced in May, and 104,489 tons will be produced in October month.

Answer:

y = 16

Step-by-step explanation:

Given that,

y varies inversely with x i.e.

[tex]y=\dfrac{k}{x}[/tex]

Where

k is a constant of proportionality

Put y = 48 and x = 6 in the above equation to find k.

So,

[tex]k=48\times 6\\\\k=288[/tex]

Now put k = 288 and x = 18 in the above equation to find y.

[tex]y=\dfrac{288}{18}\\\\y=16[/tex]

So, the value of y is equal to 16 when x = 18.

The situation represents a geometric sequence because the successive y-values have a common ratio of 1.05.

A geometric series is a series in which the division of any consecutive two terms will be the same.

here, we have,

to determine the situation:

The given parameters are:

Initial = 5200

Rate = 5%

Because the population by 5% every year, then the situation is a geometric sequence.

The common ratio is then calculated as:

Ratio = 1 + Rate

This gives

Ratio = 1 + 5%

Evaluate

Ratio = 1.05

Hence, the situation represents a geometric sequence because the successive y-values have a common ratio of 1.05.

Answer:

The answer is A

Step-by-step explanation:

I just took the test and it was the answer!

The equation for the increase in length and width of the rectangular pig pen is x² + 18x - 88 = 0.

The correct option is (A).

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement.

As per the given data:

The dimensions for the pig pen Jenna has is given.

The area of the pig pen is to be increased to 168 m² by increasing the length and width by the same amount.

Length of the rectangular pig pen = 10 m

Width of the rectangular pig pen = 8 m

Now, let's say that the length and width of the pig pen is increased by x m.

length = 10 + x

width = 8 + x

The expression for the area of the pig pen will be:

Area = length × width

168 = [10 + x][8 + x]

168 = 80 + 10x + 8x + x²

x² + 18x - 88 = 0

The equation for the increase in length and width of the rectangular pig pen is x² + 18x - 88 = 0.

Hence, The equation for the increase in length and width of the rectangular pig pen is x² + 18x - 88 = 0.
