There are 364 solutions to the given inequality: x1 + x2 + x3 <= 11.

To get the solution of the inequality x1 + x2 + x3 <= 11, we first need to include an additional variable in the inequation to write in as an equation.

Therefore, let the additional variable be x4.

Thus, equation is x1 + x2 + x3 + x4 = 11

The number of solutions of an equation can be calculated by the formula,

\(( \left \ {{n+ r - 1} \atop {n}} \right.)\), where n is the constant value of the equation and r is the number of variables in the equation.

In this case, n = 11 and r = 4

Therefore,

\(( \left \ {{n+ r - 1} \atop {n}} \right.)\) = \(( \left \ {{11+ 4 - 1} \atop {11}} \right.)\) = \(( \left \ {{14} \atop {3}} \right.)\)

= 14 * 13 * 12 * 11!/(3 * 2 * 1 * 11!)

=2184/6 = 364

Therefore, there are 364 possible solutions of the inequality.

Step-by-step explanation:

Answer:

 (b)  4

Step-by-step explanation:

You want the approximate number of items that should be produced to minimize production costs.

The graph shows cost is lowest when the number of items produced is 4.

4 items should be produced to minimize production cost.

For the following examples:

3. Dave's truck has a fuel capacity of 180 US gallons, but it is only one-quarter full, which means he needs 3/4 of 180 gallons = 135 gallons of diesel fuel.

To convert gallons to liters, multiply by 3.78541 (1 gallon = 3.78541 liters).

So Dave needs 135 gallons x 3.78541 liters/gallon = 511.66535 liters of diesel fuel.

The cost of diesel fuel is 94.9 C per liter, so the total cost for Dave to refill his truck is 511.66535 liters x 94.9 C/liter = $485.63.

4. To determine the volume of concrete Greg will need for his driveway, we first convert the dimensions to meters:

20 feet = 6.096 meters, 36 feet = 10.9728 meters, and 4 inches = 0.1016 meters.

Then use the formula for the volume of a rectangular solid: volume = length x width x height.

So the volume of concrete needed for Greg's driveway is 6.096 meters x 10.9728 meters x 0.1016 meters = 6.801 cubic meters.

The cost of the concrete is $135 per cubic meter, so the total cost for the concrete that he will need for his driveway is 6.801 cubic meters x $135/cubic meter = $918.14.

5. The volume of each planting box is 48 inches x 24 inches x 18 inches = 20736 cubic inches.

To convert cubic inches to cubic yards, divide by 46656 (1 cubic yard = 46656 cubic inches).

So each planter box requires 20736 cubic inches / 46656 cubic inches/cubic yard = 0.44444 cubic yards of potting soil.

Susan needs to build 35 planting boxes, so she will need 35 x 0.44444 cubic yards = 15.5554 cubic yards of potting soil.

Holland Growers charges $17 per cubic yard of potting soil, so the cost from them will be 15.5554 cubic yards x $17/cubic yard = $264.45.

Night Growers charges $21.50 per cubic meter of potting soil, which is equivalent to $16.34 per cubic yard (1 cubic meter = 1.30795 cubic yards).

So the cost from Night Growers will be 15.5554 cubic yards x $16.34/cubic yard = $254.36.

Therefore, the total cost of the topsoil she needs from each supplier is $264.45 from Holland Growers and $254.36 from Night Growers.

The complete solution is summarized below:

lim x→2 + f(x) = 3

lim x→2 −f(x) = 1

lim x→2 f(x) DNE.

We have been provided with the following graph:

Limit from the right-hand side (x → 2+)

For the limit from the right-hand side (x → 2+), we approach the point 2 from the right-hand side.

From the graph, we can see that the value of y is approaching 3.

Therefore, lim x→2 +f(x) = 3

Limit from the left-hand side (x → 2-)

For the limit from the left-hand side (x → 2-), we approach the point 2 from the left-hand side.

From the graph, we can see that the value of y is approaching 1.

Therefore, lim x→2 −f(x) = 1

Overall Limit (x → 2)

When we look at the overall limit as x → 2, we can see that both the limit from the right-hand side and the limit from the left-hand side approach different numbers.

As the limit from both sides is different, we can say that the overall limit does not exist.

Therefore, lim x→2 f(x) DNE.

The complete solution is summarized below:

lim x→2 + f(x) = 3

lim x→2 −f(x) = 1

Answer:

A

Step-by-step explanation:

6x - 5 > - 29 ( add 5 to both sides )

6x > - 24 ( divide both sides by 6 )

x > - 4 → A

We are given with a inequality and we have to find the solution for it . So , let's start :

\({:\implies \quad \sf 6x-5\> -29}\)

Adding 5 to both sides :

\({:\implies \quad \sf 6x-\cancel{5}+\cancel{5}\>-29+5}\)

\({:\implies \quad \sf 6x\> -24}\)

Dividing both sides by 6 ;

\({:\implies \quad \sf \dfrac{\cancel{6}\cdot x}{\cancel{6}}\> -\dfrac{24}{6}}\)

\({:\implies \quad \bf \therefore \quad \underline{\underline{x \> -4}}}\)

Hence , Option A) x > - 4 is correct :D

Whenever dividing or multiplying an inequality by a -ve , so we have to tilt the sign too , while if we are multiplying or dividing with a +ve , so sign will remain the same , For example like if we are given with x > y , and we multiply both sides by -1 . So , it will then become - x < - y

The following is the least appropriate measure of central tendency for a data set that contains outliers is 2ndquartile.

A single number that seeks to characterise a set of data by pinpointing the centre position within that set of data is referred to as a measure of central tendency. As a result, measures of central location are occasionally used to refer to measures of central tendency. They also fit within the category of summary statistics. You are probably most familiar with the mean (sometimes known as the average), but there are additional central tendency measures, including the median and the mode.

The mean, median, and mode are all reliable indicators of central tendency, however depending on the situation, some indicators are more useful than others.

The website which is cheaper for Caroline to buy the spice mix is French website.

Given data ,

Let's calculate the total cost for Caroline from both websites and determine which one is cheaper.

British website:

Price for 100 g = (£0.90 / 25 g) * 100 g = £3.60

Since the British website offers free delivery, the total cost remains £3.60.

French website:

Price for 100 g = (€1.20 / 50 g) * 100 g = €2.40

Delivery cost = €0.80

On simplifying the equation , we get

To convert the price and delivery cost to pounds, we'll use the conversion rate: €1 = £0.85.

Price in pounds = €2.40 * £0.85 = £2.04

Delivery cost in pounds = €0.80 * £0.85 = £0.68

Total cost = Price in pounds + Delivery cost = £2.04 + £0.68 = £2.72

Comparing the total costs:

British website: £3.60

French website: £2.72

Hence , Caroline would pay £2.72 for the spice mix from the cheaper website, which is the French website.

What is the volume of the rectangular prism?

To find the volume of a rectangular prism, we multiply the length of the prism by the width of the prism by the height of the prism.

The volume of the rectangular prism is 2 cm x 3 cm x 8 cm = 48 cubic cm.

A sphere with volume V has a radius r given by the formula:

V = (4/3) * pi * r³

We can rearrange the formula to solve for r:

r = (V * 3 / 4 * pi)^(1/3)

Substituting the volume of the rectangular prism for V:

r = (48 * 3 / 4 * pi)⁻³

The value of r = (48 * 3 / 4 * pi)^(1/3) is approximately equal to 2.15.

1.738 kg of coffee are required to produce 200 cups of coffee.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal.

Now it is given that,

1 pound of coffee yield 50 cups.

Since 1 pound = 0.4535 kg

Therefore, 0.4535 kg of coffee yield 50 cups.

Let x be the kgs of coffee that yields 200 cups of coffee.

Thus by proportion we can write,

0.4345 / 50 = x / 200

By cross multiplication we get,

50 x = 0.4345 * 200

⇒ 50x = 86.9

⇒ x = 86.9 / 50

⇒ x = 1.738 kgs

The probability that the installation time is less than or equal to 30 minutes is: P(X ≤ 30) = 4.23 × 30 = 126.9%

Let's discuss the probability density function (pdf) for the installation time X of a certain software package.

Given that the pdf is f(x) = 4.23 when 0 < x < 1, and f(x) = 0 otherwise, we can find the probability that the installation time is between two specific values, say, a and b.

To find the probability that the installation time X is between a and b (0 ≤ a < b ≤ 1), you need to integrate the pdf f(x) over the interval [a, b].

1. Write down the integral of the pdf f(x) over the interval [a, b]:

  P(a < X < b) = ∫[a, b] f(x) dx

2. Since f(x) = 4.23 when 0 < x < 1, substitute this value into the integral:

  P(a < X < b) = ∫[a, b] 4.23 dx

3. Integrate the function with respect to x:

  P(a < X < b) = [4.23x]_[a, b]

4. Evaluate the integral at the limits a and b:

  P(a < X < b) = 4.23b - 4.23a
To find the probability that the installation time is less than or equal to a certain value t, we need to integrate the probability density function from 0 to t:

P(X ≤ t) = ∫[0, t] f(x) dx = ∫[0, t] 4.23 dx = 4.23t

Therefore, the probability that the installation time is less than or equal to 30 minutes is:

P(X ≤ 30) = 4.23 × 30 = 126.9%

Now, you have the probability formula that the installation time X is between a and b. Remember, this formula is only valid for 0 ≤ a < b ≤ 1.

Suppose the installation time (in minutes) required for certain software package is continuous random variable with the probability density function 4x3 if 0 < x < 1 f(x) = {0 otherwise Find the expected value of the installation time in minutes = E(X) (Provide the exact answer:)
