Answer:

Step-by-step explanation:

1. Since we know that Lila wants to use 1 cup of pretzels, we can multiply 1/2 x 1/2, which is 1.

2. Now that we multiplied 1/2 by 1/2, we have to multiply 1 1/4 by 1/2.

So 5/4 x 1/2 is 5/8.

3. Lila will need 5/8 cups of raisins.

The length of segment CB in trapezoid CBAD is 11.

In a trapezoid, the midsegment is the line segment that joins the midpoints of the two non-parallel sides. In this case, KJ is the midsegment of trapezoid CBAD, which means that it is parallel to both CB and AD, and its length is equal to the average of the lengths of CB and AD.

We are given that;

CB=4x-13

KJ=6x-18

DA=25

we can use the formula for the midsegment of a trapezoid to set up an equation and solve for x:

KJ = (CB + AD) / 2

6x - 18 = (4x - 13 + 25) / 2

6x - 18 = (4x + 12) / 2

6x - 18 = 2x + 6

4x = 24

x = 6

Now that we have found the value of x, we can substitute it back into the expression for CB to find its length:

CB = 4x - 13 = 4(6) - 13 = 11

Therefore, the answer of the given trapezoid will be 11.

Answer:

£78

Step-by-step explanation:

Given:

£130 is divided between  Dan, David & Mark so that Dan gets twice as much as David, and David gets three times as much as Mark.

To find: How much does Dan get?

Solution:

Let D represents Dan, V represents David and M represents Mark.

Now we have given that Dan gets twice as much as David:  

              D = 2V          .....(i)  

David gets three times as much as Mark

              V = 3M         ......(ii)

The total sum of money is D + V + M = 130  ........(iii)

Putting (i), (ii) in (iii), we get:

             2V + V + V/3 = 130

             6V + 3V + V = 390

             10V = 390

             V = 39

Putting the value of V in (i), we get:

             D = 2(39)

            D = £78

Therefore, Dan gets £78

The Venn diagram represents the memberships of the 11 students in Ms. Cox's class in the Math Club and the Tennis Club. We need to calculate probabilities based on the given events. The requested probabilities are as follows: P(B), P(A or B), P(A), and P(4)+P(B)-P(A and B).

Let's calculate each probability step by step:

1. P(B) represents the probability of selecting a student who is in the Tennis Club.

  Counting the number of students in the Tennis Club, we see that there are 4 students (Juan, Tammy, Christine, and Kira) who are members of the Tennis Club.

  The total number of students is 11.

  Therefore, P(B) = 4/11.

2. P(A or B) represents the probability of selecting a student who is either in the Math Club or the Tennis Club.

  To calculate this probability, we need to find the total number of students in either club.

  Looking at the diagram, we can see that there are 6 students in the Math Club (Omar, Christine, Kira, Elsa, Boris, and Juan) and 4 students in the Tennis Club (Juan, Tammy, Christine, and Kira).

  However, one student, Juan, is counted twice since he is a member of both clubs.

  So, the total number of students in either club is 6 + 4 - 1 = 9.

  Therefore, P(A or B) = 9/11.

3. P(A) represents the probability of selecting a student who is in the Math Club.

  From the diagram, we can see that there are 6 students in the Math Club (Omar, Christine, Kira, Elsa, Boris, and Juan).

  The total number of students is 11.

  Therefore, P(A) = 6/11.

4. P(4) represents the probability of selecting student number 4.

  Since there are 11 students, each student has an equal chance of being selected.

  Therefore, P(4) = 1/11.

5. P(A and B) represents the probability of selecting a student who is a member of both the Math Club and the Tennis Club.

  From the diagram, we can see that only one student, Juan, is a member of both clubs.

  Therefore, P(A and B) = 1/11.

Now, let's calculate P(4) + P(B) - P(A and B):

P(4) = 1/11

P(B) = 4/11

P(A and B) = 1/11

P(4) + P(B) - P(A and B) = 1/11 + 4/11 - 1/11 = 4/11

Therefore, the probability that is equal to P(4) + P(B) - P(A and B) is P(B).

the main answer is that the mean value of the activity time is 21.67. This is calculated using the formula (optimistic + 4 * most likely + pessimistic) / 6.

To find the mean value of the activity time, we can use the three estimates provided: optimistic, most likely, and pessimistic time.

1. The optimistic time is the shortest possible time for completing the activity, which is 11 units.
2. The most likely time is the time that is most likely to be taken to complete the activity, which is 21 units.
3. The pessimistic time is the longest possible time for completing the activity, which is 35 units.

To calculate the mean value, we can use the following formula:
Mean value = (optimistic + 4 * most likely + pessimistic) / 6

Substituting the given values, we get:
Mean value = (11 + 4 * 21 + 35) / 6

Calculating the numerator first:
11 + 4 * 21 + 35 = 11 + 84 + 35 = 130

Now, we can calculate the mean value:
Mean value = 130 / 6

Dividing 130 by 6, we get:
Mean value = 21.67 (rounded to two decimal places)

Therefore, the mean value of the activity time is 21.67.

the main answer is that the mean value of the activity time is 21.67. This is calculated using the formula (optimistic + 4 * most likely + pessimistic) / 6.

In summary d²y/dx² in terms of x and y is given by: d²y/dx² = 3/2 x + 1/4 y

Why is it?

To find d²y/dx², we need to differentiate the given differential equation with respect to x:

dy/dx = x² - 1/2 y

Differentiating both sides with respect to x:

d²y/dx² = d/dx(x² - 1/2 y)

d²y/dx² = d/dx(x²) - d/dx(1/2 y)

d²y/dx² = 2x - 1/2 d/dx(y)

Now, we need to express d/dx(y) in terms of x and y. To do this, we differentiate the original differential equation with respect to x:

dy/dx = x² - 1/2 y

d/dx(dy/dx) = d/dx(x² - 1/2 y)

d²y/dx² = 2x - 1/2 d/dx(y)

d²y/dx² = 2x - 1/2 (d²y/dx²)

Substituting this expression for d²y/dx² back into our previous equation, we get:

d²y/dx² = 2x - 1/2 (2x - 1/2 y)

d²y/dx² = 2x - x/2 + 1/4 y

d²y/dx² = 3/2 x + 1/4 y

Therefore, d²y/dx² in terms of x and y is given by:

d²y/dx² = 3/2 x + 1/4 y

This is true because a probability distribution is a mathematical function that provides the probabilities of occurrence of different possible outcomes in an experiment.

The area under the probability distribution is a measure of the probability of all the possible outcomes. Since the sum of all the probabilities of all the possible outcomes must be 1, the total area under the probability distribution must also be 1. This is because the probability of an event happening is the area under the curve of the probability distribution at that event. Thus, the total area under the probability distribution must always equal 1.

The expected number of letters that get placed into their proper envelopes is approximately 4.43.

This is an example of the classic "derangement" problem, where we want to find the number of permutations of n objects that leave none of the objects in their original position. In this case, we can consider each addressed letter and its corresponding envelope as a pair, so we have 12 pairs of objects.

The number of ways to randomly place these 12 pairs into envelopes is 12! (the total number of permutations). To count the number of permutations where none of the pairs are in their original envelopes (i.e., all are "deranged"), we can use the principle of inclusion-exclusion

The total number of permutations is 12!.

We subtract the number of permutations where at least one pair is in its original envelope. There are 12 ways to choose the fixed pair, and 10! ways to permute the remaining 10 pairs, so there are 12 × 10! permutations where at least one pair is fixed.

However, we have subtracted twice the permutations where two pairs are fixed, so we need to add those back in. There are 12 choose 2 ways to choose two fixed pairs, and 8! ways to permute the remaining 8 pairs, so there are 12 choose 2 × 8! permutations where two pairs are fixed.

Continuing this pattern, we subtract the permutations where three pairs are fixed, add back in the permutations where four pairs are fixed, and so on. However, since there are only 12 pairs, we can stop after the term where 12 pairs are fixed (i.e., none of the pairs are deranged).

Putting it all together, we get

number of derangements = 12! - 12 × 10! + 12 choose 2 × 8! - 12 choose 3 × 6! + 12 choose 4 × 4! - 12 choose 5 × 2! + 12 choose 6 × 0!

Using a calculator or computer program, we can simplify this to 2,290,792. Therefore, the expected number of letters that get placed into their proper envelopes is 2,290,792 / 12! ≈ 0.3679. So we expect about 0.3679 × 12 ≈ 4.43 letters to be placed into their proper envelopes.

We can proved that the sum of the squares of the diagonals of a parallelogram is equal to the sum of the squares of its sides.

Let's denote the vertices of the parallelogram as A, B, C, and D, with O as the midpoint of AC and BD.

First, we can see that triangles ABO and CDO are congruent by the Side-Side-Side (SSS) postulate, since they share side BD, and both have sides AB and CO of equal length due to O being the midpoint of BD. Therefore, angles AOB and COD are congruent, and we can denote their measure as θ.

Using the Law of Cosines in triangles ABO and CDO, we can express the squares of the diagonals AC and BD in terms of the sides of the parallelogram:

AC² = AB² + BC² - 2(AB)(BC)cosθ

BD² = AB² + BC² + 2(AB)(BC)cosθ

Adding these two equations together, we get:

AC² + BD² = 2(AB² + BC²)

which is the desired result. Therefore, we have shown that the sum of the squares of the diagonals of a parallelogram is equal to the sum of the squares of its sides.
