As a result, it would take 5 pretzel makers 22.6 minutes, or around 0.376 hours, to manufacture 88 pretzels.

To answer mathematical issues involving proportional relationships between various quantities, one can utilize the unitary method. Finding the value of one unit of a quantity and using that value to determine the value of another number of units is what it entails. In business and finance, the unitary technique is frequently used to address issues with cost, price, and quantity. The link between several units of measurement is also computed in physics and other fields.

given

To begin, we can apply the formula:

(Workers' Count) x (Efficiency) x (Time) = (amount of work)

To achieve this, multiply the total quantity of pretzels produced by the two pretzel makers by the sum of the labor hours worked by the number of workers:

One pretzel maker's productivity is calculated as follows: (444 pretzels / 2 workers x 6 hours) = 37 pretzels per worker-hour.

The time it would take for five pretzel producers to produce 88 pretzels may therefore be calculated using this efficiency:

37 pretzels were consumed each worker hour multiplied by five workers yields 88 pretzels.

By solving for time, we obtain:

Time is calculated as follows: 88 pretzels / (5 workers x 37 pretzels per worker-hour) = 0.376 hours.

As a result, it would take 5 pretzel makers 22.6 minutes, or around 0.376 hours, to manufacture 88 pretzels.

Answer: The total amount of the hummingbirds' weight is 15 grams.

Step-by-step explanation:

As it is shown in the dot graph, the four hummingbirds' weigh is recorded to the nearest gram.

Hummingbird 1 - 2 1/2

Hummingbird 2 - 3

Hummingbird 3 -  4 1/2

Hummingbird 4 - 5

2 1/2 + 4 1/2 = 7

3 + 5 = 8

Seven plus eight equals to fifteen. Therefore, the total weight of all four hummingbirds is 15.

Answer:

Step-by-step explanation:

180 ÷ 20 = 9

Original Price = 9 x £2.80 = £25.2

Discounted price = £25.2 - (£25.2 x 0.30) = £17.55

In a sale, 180 carrots would cost £17.55.

Thus, the chance according to the equation that the average actual weight for the [tex]100 weights[/tex] is higher than [tex]24.9 pounds[/tex] is roughly [tex]0.9582[/tex]

An equation in mathematics is a declaration of the equivalence of two expressions. Two parts of an equation are divided by the algebraic symbol ([tex]=[/tex]). As an example, the assertion "[tex]2x+3=9[/tex]" is supported by the argument that it is true.

Finding the value or values of the variable(s) needed to make the equation correct is the aim of equation solving. It is possible to create regular or nonlinear, straightforward or complex equations that include one or more variables.

For instance, the variable[tex]x[/tex] is raised to the second degree in the equation "[tex]x^{2} +2x-3[/tex]". In many areas of mathematics, such as algebra, calculus, or geometry, lines are used.

The weights are distributed evenly, with a minimum value of [tex]24[/tex] and a highest value of [tex]26[/tex]. The average of the lowest and maximum values, which is the mean weight of a single weight, is

[tex](mean weight)= (24+26)/2 = 25 pounds[/tex]

The standard deviation of a single weight is the difference between the maximum and minimum values divided by[tex]\sqrt{12}[/tex] (since there are [tex]12[/tex]possible values between [tex]24[/tex] and [tex]26[/tex]), which is

[tex]Standard deviation = (24+26)/\sqrt{12}[/tex]

[tex]We know (standard deviation of mean weight ) = 0.57735/\sqrt{100} =0.057735[/tex]

We must standardise this value by taking the mean weight, subtracting it, and dividing the result by the mean weight's standard deviation in order to determine the likelihood that the mean actual weight for the[tex]100[/tex]weights is higher than [tex]24.9 pounds[/tex]:

[tex]( Z- score )= (24.9-25)/0.057735 = -1.7321[/tex]

Probability is [tex]less than[/tex] [tex]-1.7321 in Z- score approx 0.0418[/tex]

However [tex]mean actual weight > 24.9[/tex] which is the complement of the probability i.e, [tex]\leq 24.9[/tex]

After subtracting the probability we found [tex]1[/tex] [tex](mean weight > 24.9)[/tex]

∴[tex]1 -0.0418 = 0.9582[/tex]

Therefore the  the average actual weight for the [tex]100 weights[/tex] is higher than [tex]24.9 pounds[/tex] is roughly [tex]0.9582[/tex]

1. The triangles are not similar because they do not have proportional set of sides.

2. Both triangles are not similar as well.

The SSS similarity theorem states that if three corresponding sides of two triangles are proportional, then the triangles are similar. "SSS" stands for "side-side-side," which refers to the three corresponding sides that are proportional.

More formally, the SSS similarity theorem can be stated as follows:

If ΔABC ~ ΔDEF, then: AB/DE = BC/EF = AC/DF (the sides are proportional)

1. QP/ML = 90/40 = 2.25

RQ/LK = 81/36 = 2.25

PR/MK = 64/28 = 2.29

Thus, this means that QP/ML = RQ/LK ≠ PR/MK. This implies the three sides are of both triangles are not proportional. Therefore, they are not similar by SSS nor any other theorem.

The reason why the green triangle is not possible given an angle of 30° and a side length of 8.73 is due to the fact that the green triangle violates the triangle inequality theorem.

According to the triangle inequality theory, any triangle's lengths of any two sides must add up to more than the length of the third side.

The triangle inequality theorem is broken in the instance of the green triangle if the second side is extended to a very long length, making the triangle's lengths of the two shorter sides (7 and 8.73) less than the length of the longer side (24).

The orange triangle, which has side lengths of 7, 15, and roughly 16.16 (determined using the Pythagorean equation), is the only one that can exist because the green triangle is impossible.

Answer:There seems to be a typo in the equation for f(x). I will assume that the correct equation is:f(x) = 4x - 25To find the first x value where g(x) > f(x), we can set the two equations equal to each other and solve for x:g(x) = f(x)

2(5)x = 4x - 25

10x = 4x - 25

6x = -25

x = -25/6

Step-by-step explanation:However, we need to check if this value satisfies the condition g(x) > f(x):g(-25/6) = 2(5)(-25/6) = -25

f(-25/6) = 4(-25/6) - 25 = -75/3 - 25/1 = -100/3Therefore, g(x) > f(x) is not true for x = -25/6. We need to keep looking for a larger value of x where g(x) > f(x).To do this, we can graph the two functions and look for the point where the graph of g(x) is above the graph of f(x). Alternatively, we can simply plug in some larger values of x and compare the values of g(x) and f(x) until we find the first x value where g(x) > f(x).Let's try plugging in x = 0:g(0) = 2(5)(0) = 0

f(0) = 4(0) - 25 = -25Since g(0) = 0 and f(0) = -25, we have g(x) > f(x) for x > 0. Therefore, the first x value where g(x) > f(x) is x = 0.

The probability that Emily chooses a blue chip and Josie chooses a red chip is 3/28.

Events that are mutually incompatible cannot take place at the same moment. If one thing happens, the other thing can't happen. For instance, if we flip a coin, receiving heads and getting tails are mutually exclusive events. The likelihood of two mutually exclusive occurrences happening simultaneously is zero.

Events that are independent of one another are said to be independent. The likelihood of the other event happening is unaffected if one event happens.

Given, 3 blue chips and 2 red chip from a total of 8 chip we have:

P(Emily chooses blue and Josie chooses red) = P(Emily chooses blue) × P(Josie chooses red after Emily chose blue)

= (3/8) × (2/7)

Two potential locations for drilling are under consideration by an oil corporation.

a) The estimated profit is higher at Site A.

b) We can state that Site A has a larger expected profit than Site B by $17 million because the expected profit for Site A is higher than the expected loss for Site B.

To find the expected profit for each site, we need to multiply the profit from finding oil by the probability of finding oil and subtract the loss from not finding oil multiplied by the probability of not finding oil.

For Site A:

Expected profit = (Profit if oil is found x Probability of finding oil) - (Loss if no oil is found x Probability of not finding oil)

Expected profit = ($120 million x 0.2) - ($20 million x 0.8)

Expected profit = $24 million - $16 million

Expected profit = $8 million

For Site B:

Expected profit = (Profit if oil is found x Probability of finding oil) - (Loss if no oil is found x Probability of not finding oil)

Expected profit = ($180 million x 0.1) - ($30 million x 0.9)

Expected profit = $18 million - $27 million

Expected profit = -$9 million

Therefore, Site A has the larger expected profit of $8 million, while Site B has an expected loss of $9 million.

Since the expected profit for Site A is greater than the expected loss for Site B, we can say that Site A has a larger expected profit than Site B by $17 million ($8 million - (-$9 million)), which is the difference between their expected profits.

A 0.166 probability that they are over 45 years old is discovered using its notion from histogram.

A histogram is a form of graph that is used to show how a dataset is distributed. The horizontal axis shows the range of values in the dataset, while the vertical axis represents the frequency with which those values occur. It is a graphical depiction of a frequency table. Each bar's height corresponds to the number of observations that occur within a given bin, which is created by dividing the data into equal intervals known as bins.

In statistics and data analysis, histograms are frequently used to examine a distribution's form, particularly its central tendency, variability, and skewness. They are especially helpful for locating patterns and trends in the data as well as for spotting outliers, gaps, and clusters. Moreover, histograms can be used to contrast several datasets or look at how a dataset has changed over time.

The number of desired outcomes divided by the total number of outcomes yields a probability.

The conditional probability that a randomly selected participant wore leather pants and played an acoustic guitar is 6/25. Therefore, the answer is option D. 6/25.

Conditional probability is the probability that an event will occur given that another event has already occurred.

It is denoted by P(A|B), where A and B are events, and the vertical line | indicates "given that" or "conditional on".

The conditional probability of an event A given event B is defined as the probability of both A and B happening divided by the probability of B happening:

P(A|B) = P(A and B) / P(B)

In this case, the event A is playing an acoustic guitar and the event B is wearing leather pants.

We can start by finding the probability of wearing leather pants:

P(B) = (6 + 9) + (3 + 7) = 25

This is because there are a total of 6 contestants wearing leather pants and 19 contestants in total.

Next, we need to find the probability of both wearing leather pants and playing an acoustic guitar:

P(A and B) = 6

This is because there are 6 contestants wearing leather pants and playing an acoustic guitar.

Now we can use the formula to find the conditional probability:

P(A|B) = P(A and B) / P(B) = 6 / 25
