the probability of picking 3 red marbles if each marble is NOT returned to the bag before the next marble is picked is14/285.
Define probabilityProbability is a measure of the likelihood or chance that a particular event will occur, expressed as a number between 0 and 1. A probability of 0 means that the event is impossible, while a probability of 1 means that the event is certain.
After the first red marble is drawn, there will be 19 marbles left in the bag, of which 7 are red.
So, the probability of picking a red marble on the second draw, given that the first marble was red and not returned to the bag, is 7/19.
Similarly, after the second red marble is drawn, there will be 18 marbles left in the bag, of which 6 are red.
So, the probability of picking a red marble on the third draw, given that the first two marbles were red and not returned to the bag, is 6/18 or 1/3.
Therefore, the probability of picking 3 red marbles in a row is:
(8/20) x (7/19) x (6/18) = 14/285
So, the answer is 14/285.

A greengrocer normally sells 20 carrots for £2.80. In a sale, the cost of the carrots is reduced by 30%. Work out how much 180 carrots cost in the sale. Give your answer in pounds
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.
Why is the green triangle not possible given an angle of 30°?
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.
What is 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.

Samedy says that the total number of brothers and sisters that the class has is 24, because there will be 24 dots above the number line on the line plot. Use the drop-down menus to complete the statement below.
Answer:
Samedy's statement is false. in total the class has 56 brothers and sisters
Step-by-step explanation:
Answer:
A. Samedy's statement is incorrect.
B. In total, the class has 71 brothers and sisters.
To arrive at this answer, we can use the information given in the problem to calculate the total number of brothers and sisters:
7 students have 2 siblings each, so there are 14 siblings in total.
4 students have 1 sibling each, so there are 4 siblings in total.
6 students have 3 siblings each, so there are 18 siblings in total.
The remaining students have 4 siblings each, so there are 4 x (24 - 7 - 4 - 3 - 6) = 4 x 4 = 16 siblings in total.
Adding all of these up, we get a total of 14 + 4 + 18 + 16 = 52 siblings. Therefore, Samedy's statement is incorrect, as the class has 52 siblings and not 24.

given the equations below what is the frist x value where g(x)>f(X)
f(X)=4X=25
g(X)=2(5)x
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.
An oil company is considering two sites on which to drill, described as follows: Site A: Profit if oil is found: $120 million Site B: Profit if oil is found: $180 million Loss if no oil is found: $20 million Loss if no oil is found: $30 million Probability of finding oil: 0.2 Probability of finding oil: 0.1
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.

IF I A LIQUID IS AT A TEMPERATURE OF 16.9 AND RISES AT A RATE OF 2.3 AND A SOLID IS AT A TEMPERATURE OF 30.7 AND DECREASES AT A RATE OF 6.9 how long will it take for them to be at the same temperature in minutes
Answer:
The number of minutes it will take for a liquid and a solid to reach the same temperature is 3 minutes.
Step-by-step explanation:
You know that the temperature of liquid at 16.9°C is decreasing at a rate of 2.3°C per minute. Then, the temperature of the liquid after t minutes, as its value decreases, will be the difference between the initial temperature of 16.9 ° C and the temperature after t minutes. So:
temperature of the liquid= 16.9°C - 2.3 °C/minute * t
On the other side, you know that the temperature of a solid at 30.7°C is decreasing at a rate of 6.9°C per minute. Then, the temperature of the solid after t minutes, as its value decreases, will be the difference between the initial temperature of 30.7°C and the temperature after t minutes. So:
temperature of the solid= 30.7°C - 6.9 °C/minute * t
You want to calculate the number of minutes it will take for a liquid and a solid to reach the same temperature. This is:
temperature of the liquid= temperature of the solid
16.9°C - 2.3 °C/minute * t= 30.7°C - 6.9 °C/minute * t
Solving:
- 2.3 °C/minute * t= 30.7°C - 6.9 °C/minute * t - 16.9°C
- 2.3 °C/minute * t + 6.9 °C/minute *t= 30.7°C - 16.9°C
4.6 °C/minute * t = 13.8 °C
t=3 minutes
So the number of minutes it will take for a liquid and a solid to reach the same temperature is 3 minutes.
A manufacturer produces 25-pound lifting weights. The lowest actual weight is 24 pounds, and the highest is 26 pounds. Each weight is equally likely so the distribution of weights is uniform. A sample of 100 weights is taken.
Find the probability that the mean actual weight for the 100 weights is greater than 24.9. (Round your answer to four decimal places.)
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]
What is equation?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]

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

What is the image point of (-9,-5) after the transformation T-5,00 D₂?
attempt 11 out of 20/problem 1 out of ma
C
Thus, following the transformation T-5,00 D2, the image point of (-9,-5) is (-8,-10). Hence, choice C is the right response.
What is transformation ?The term "transformations" refers to the movements or adjustments that can be made to a geometric shape or object, such as turning, reflecting, translating, processes in an organization, or resizing. With these procedures, the original form or object can retain its geometry, angles, and other geometric attributes while changing its position, size, and orientation. Geometry, photography, and other disciplines frequently employ transformations to manipulate and examine patterns and shapes.
given
Applying the translation T-5,00 to the point (-9,-5) first yields (-9-(-5),-5+0) =, which we can use to determine the image point of (-9,-5) following the transformation T-5,00 D2 (-4,-5).
Then, we dilate the point (-4, -5) using the formula (2(-4,2(-5)) = (-8,-10).
Thus, following the transformation T-5,00 D2, the image point of (-9,-5) is (-8,-10). Hence, choice C is the right response.

If 2 pretzel makers can make 444 pretzels in 6 hours, how long does it take 5 pretzel makers to make 88 pretzels?
As a result, it would take 5 pretzel makers 22.6 minutes, or around 0.376 hours, to manufacture 88 pretzels.
what is unitary method ?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.

Which of the following is an example of an inequality?
The equation which is an example of an inequality include the following: C. 4x > -16
What is an inequality?In Mathematics and Geometry, an inequality simply refers to a mathematical relation that is typically used for comparing two (2) or more numerical data and variables in an algebraic equation based on any of the inequality symbols;
Less than (<).Greater than (>).Greater than or equal to (≥).Less than or equal to (≤).In this context, we can reasonably infer and logically deduce that the only equation with an inequality symbol is 4x > -16 and as such, it is an example of an inequality.
By evaluating, we have:
4x > -16
x > -16/4
x > -4
In conclusion, we can logically deduce that x is greater than negative four (-4).
