Answer: while solving an equation involving fractions we eliminate the fraction by multiplying the LCD of all the denominators present in the equation . LCD means Least common Denominator so for this question when we try to eliminate the denominator we first try to find the LCM (2,4,6) because that will give us the LCD.
2=2
4=2·2
6=2·3
LCM = 2·2·3
LCM = 12
It means we need to multiply the 12 to each term of equation to eliminate the fractions before solving.

a bag contains three red marbles, two green ones, one lavender one, one yellow, and three orange marbles. hint [see example 7.] how many sets of five marbles include at least two red ones?
Answers
There are 246 sets of five marbles that include at least two red ones. We can use the principle of inclusion-exclusion, as hinted in Example 7.
First, we can find the total number of sets of five marbles, which is the number of ways to choose five marbles out of ten without any restrictions. This can be calculated using the formula for combinations: C(10, 5) = 252
Next, we need to subtract the number of sets that do not include any red marbles. We can choose five marbles from the seven non-red marbles in C(7, 5) ways: C(7, 5) = 21
However, we have overcounted the sets that include only one red marble, so we need to add them back. We can choose one red marble from the three available in C(3, 1) ways, and we can choose four non-red marbles from the six available in C(6, 4) ways: C(3, 1) * C(6, 4) = 45
Finally, we also need to add back the sets that include exactly one red marble and no other red marbles, which we subtracted twice. We can choose one red marble from the three available in C(3, 1) ways, and we can choose three non-red marbles from the six available in C(6, 3) ways: C(3, 1) * C(6, 3) = 60
Putting it all together using the principle of inclusion-exclusion, we get: Number of sets with at least two red marbles = C(10, 5) - C(7, 5) - C(3, 1) * C(6, 4) + C(3, 1) * C(6, 3) = 252 - 21 - 45 + 60 = 246
Therefore, there are 246 sets of five marbles that include at least two red ones.

Find a vector orthogonal to both 2, 2, 0 and to 0, 2, 5 of the form 1
Answers
The vector orthogonal for both vectors is \((20, -10, -4) / \sqrt{444}\) = (\(20 / \sqrt{444}\), \(-10 / \sqrt{444}\), \(-4 / \sqrt{444}\))
What is an orthogonal vector?
An orthogonal vector is a vector that is perpendicular to another vector in a given space. In other words, two vectors are orthogonal if their dot product is equal to zero.
To find a vector orthogonal to both 2, 2, 0 and 0, 2, 5 of the form 1, we can take the cross product of the two vectors, which results in a vector that is orthogonal to both. The cross product of 2, 2, 0 and 0, 2, 5 is given by:
(2, 2, 0) x (0, 2, 5) = (20, -10, -4)
So, a vector orthogonal to both 2, 2, 0 and 0, 2, 5 is given by (20, -10, -4). We can normalize this vector by dividing it by its magnitude, which is equal to sqrt(20^2 + (-10)^2 + (-4)^2) = sqrt(444). The normalized vector will be of the form 1:
\((20, -10, -4) / \sqrt{444}\) = (\(20 / \sqrt{444}\), \(-10 / \sqrt{444}\), \(-4 / \sqrt{444}\))
Hence, the vector orthogonal for both vectors is \((20, -10, -4) / \sqrt{444}\) = (\(20 / \sqrt{444}\), \(-10 / \sqrt{444}\), \(-4 / \sqrt{444}\)).

(a) P(A∩B) =
(b) P (A∣B)=
Answers
The values of P(A∩B) and P(A|B) are 0.165 and 0.3667, respectively.
Given:Event A occurs with probability 0.18.Event B occurs with probability 0.45.
P(A∪B) = 0.465.
Let us solve the above question step by P(A∩B)P(A∪B) = P(A) + P(B) - P(A∩B)0.465 = 0.18 + 0.45 - P(A∩B)P(A∩B) = 0.18 + 0.45 - 0.465P(A∩B) = 0.165P(A∩B) = 0.165)
P(A|B) = P(A∩B) / P(B)P(A|B) = 0.165 / 0.45P(A|B) = 0.3667P(A|B) = 0.3667 (rounded to four decimal places)
In this problem, we are given that Event A occurs with probability 0.18 and Event B occurs with probability 0.45 and P(A∪B) = 0.465 .
We are asked to find:(a) P(A∩B)(b) P (A∣B).
P(A∩B)For two events A and B, the probability of their union can be found using the formula: P(A∪B) = P(A) + P(B) - P(A∩B).
Substituting the given values, we have:0.465 = 0.18 + 0.45 - P(A∩B)Solving the above equation for P(A∩B), we get:P(A∩B) = 0.165Therefore, P(A∩B) = 0.165.(b) P(A|B).
The conditional probability P(A|B) can be found using the formula:P(A|B) = P(A∩B) / P(B).
Substituting the given values, we have:P(A|B) = 0.165 / 0.45Therefore, P(A|B) = 0.3667.Rounding it to four decimal places, we get:P(A|B) = 0.3667.
Therefore, the values of P(A∩B) and P(A|B) are 0.165 and 0.3667, respectively.

Speed is the rate of movement of anything at a specific time. Average speed refers to the average speed during the course of a journey. Typically, average speed refers to the speed of moving objects like cars, trains, and aircraft. It is frequently expressed in kilometers per hour (kph) or miles per hour (mph) (kph).
In many different disciplines, such as physics, astronomy, and transportation, average speed is employed.

- Activity A has a duration of 5 days and has no predecessor.
- Activities B, C, and D have durations of 8, 7, and 6 days respectively, and their predecessors are A.
- Activity E has a duration of 9 days and its predecessors are B, C, and D.
- Activity F has a duration of 10 days and its predecessors are B, C, and D.

- Slack is calculated by subtracting the earliest start time of an activity from the latest start time without delaying the project completion time.
- The earliest start time for activity F is 17 days.
- The latest start time for activity F is 19 days (project completion time is 22 days).

measures to answer the question.
∡ = (6)°
∡ = (3 + 45)°
∡ = (7)°
∡ = (4 + 2)°
∡ = (2 + 15)°
∡ = ( − 9)°
What are the angle measures of each vertex of the garden? Show your work
Answers
Answer:
x = 29
∠A = 174°
∠B = 132°
∠C = 203°
∠D = 118°
∠E = 73°
∠F = 20°
Step-by-step explanation:
Sum of interior angles of an irregular polygon = (n - 2) x 180°
where n = number of sides
The polygon has 6 sides,
therefore the sum of the interior angles = (6 - 2) x 180° = 720°
Add together all the angles, equal them to 720° and solve for x:
∠A + ∠B + ∠C + ∠D + ∠E + ∠F = 720
(6x) + (3x + 45) + (7x) + (4x + 2) + (2x + 15) + (x - 9) = 720
6x + 3x + 45 + 7x + 4x + 2 + 2x + 15 + x - 9 = 720
6x + 3x + 7x + 4x + 2x + x + 45 + 2 + 15 -9 = 720
23x + 53 = 720
23x = 720 - 53 = 667
x = 667/23 = 29
Now we have found the value of x, substitute this into the expression for each angle:
∠A = 6x = 6 x 29 = 174°
∠B = 3x + 45 = (3 x 29) + 45 = 132°
∠C = 7x = 7 x 29 = 203°
∠D = 4x + 2 = (4 x 29) + 2 = 118°
∠E = 2x + 15 = (2 x 29) + 15 = 73°
∠F = x - 9 = 29 - 9 = 20°

Answers
The maximum value of the sine function is 1, the angle corresponding to sin^(-1)(1) is π/2 or 90 degrees.
The principal value of sin^(-1)(1) is π/2 or 90 degrees.
The function sin^(-1)(x), also known as arcsin(x) or inverse sine, represents the angle whose sine is equal to x. In this case, we are looking for the angle whose sine is 1.
Since the sine function oscillates between -1 and 1, the angle corresponding to sin^(-1)(1) is the maximum value where the sine is equal to 1.
This occurs at π/2 or 90 degrees, making it the principal value for sin^(-1)(1).

Answers
The difference between the two localities is 1 speaker.
Let's solve the problems step by step:
a) To determine which of the two locations has a higher number of speakers of a language other than Spanish, we need to compare the ratios of speakers in El Cerrito and El Paseo.
In El Cerrito, 3 out of every 4 people speak a different language than Spanish. This can be written as a ratio: 3:4.
In El Paseo, 5 out of every 7 people speak a different language than Spanish. This can be written as a ratio: 5:7.
To compare the two ratios, we can find a common denominator. In this case, the least common multiple of 4 and 7 is 28.
In El Cerrito, the ratio becomes 21:28 (multiplying both sides by 7).
In El Paseo, the ratio becomes 20:28 (multiplying both sides by 4).
From the ratios, we can see that in El Cerrito, there are 21 out of 28 people who speak a different language than Spanish, while in El Paseo, there are 20 out of 28 people who speak a different language than Spanish.
Since 21 is greater than 20, El Cerrito has a higher number of speakers of a language other than Spanish.
b) The difference between the two localities can be calculated by subtracting the number of speakers in El Paseo from the number of speakers in El Cerrito.
In El Cerrito, there are 21 speakers of a different language than Spanish.
In El Paseo, there are 20 speakers of a different language than Spanish.
The difference is obtained by subtracting 20 from 21, resulting in a difference of 1 speaker.
Therefore, the difference between the two localities is 1 speaker.
