The rule of inference used to arrive at the statements s(y) and c(y) from the statement s(y) ∧ c(y) is called Simplification. Simplification allows us to extract individual components of a conjunction by asserting each component separately.

The rule of inference used in this scenario is Simplification. Simplification states that if we have a conjunction (an "and" statement), we can extract each individual component by asserting them separately. In this case, the conjunction s(y) ∧ c(y) represents the statement "y is a movie produced by Sayles and y is a movie about coal miners."

By applying Simplification, we can separate the conjunction into its individual components: s(y) (y is a movie produced by Sayles) and c(y) (y is a movie about coal miners). This allows us to conclude that there is a movie produced by Sayles (s(y)) and there is a movie about coal miners (c(y)).

Using the Simplification rule of inference enables us to break down complex statements and work with their individual components. It allows us to extract information from conjunctions, making it a useful tool in logical reasoning and deduction.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The following coordinates are from the graph.

We know that,

A function can have many-to-one but not one-to-many.

So,

We can not have (-2, 0), (-2, 3). and (3, 0) because we already have (-2, 3) and (3, -1).

If Alex sells 30 bracelets in the first month and increases her sales by 6 bracelets each month, she will sell a total of 360 bracelets in the first 12 months.

To determine the total number of bracelets Alex will sell in the first 12 months, we can use a simple arithmetic progression. Alex sells 30 bracelets in the first month, and her goal is to sell 6 more bracelets each subsequent month. This means that in the second month, she will sell 30 + 6 = 36 bracelets. In the third month, she will sell 36 + 6 = 42 bracelets, and so on.

We can observe that the number of bracelets sold forms an arithmetic sequence with a common difference of 6. To find the total number of bracelets sold in the first 12 months, we can sum the terms of this arithmetic sequence. Using the formula for the sum of an arithmetic series, which is Sn = (n/2)(2a + (n-1)d), where a is the first term, d is the common difference, and n is the number of terms, we can calculate the total number of bracelets sold.

In this case, a = 30 (the first term), d = 6 (the common difference), and n = 12 (the number of terms). Substituting these values into the formula, we get Sn = (12/2)(2(30) + (12-1)(6)) = 6(60 + 11*6) = 360.

Therefore, Alex will sell a total of 360 bracelets in the first 12 months if she meets her goal of selling 6 more bracelets each month than the previous month.

The value of x in the chord of the circle using the chord-chord power theorem is 8.

Chord - chord power theorem simply state that "If two chords of a circle intersect, then the product of the measures of the parts of one chord is equal or the same as the product of the measures of the parts of the other chord".

From the diagram:

The first chord has consist of 2 segments:

Segment 1 = 10

Segment 2 = 4

The second chord also consist of 2 sgements:

Segment 1 = 5

Segment 2 = x

Now, usig the Chord-chord power theorem:

10 × 4 = 5 × x

Solve for x:

40 = 5x

5x = 40

Divide both sides by 5

5x/5 = 40/5

x = 40/5

x = 8.

Answer:

M = 26 degrees, N = 64 degrees

Step-by-step explanation:

When 2 angles are complementary, it means they add up to 90 degrees. We can set up a system of equations to represent the situation.

M is measure of angle M

N is measure of angle N

M + N = 90 degrees

M = N - 38 (measure of angle M is 38 degrees less than measure of angle N)

We can then use the second equation to substitute in M in the first equation with N - 38

N - 38 + N = 90

2N - 38 = 90

2N = 128

N = 64 degrees

We plug this value back into the first equation to find M

M + 64 = 90

M = 26 degrees

The measure of ∠M and ∠N are 26° and 64° respectively.

Supplementary angles sum to 180°.If two angles are supplementary their sum is 180° and sum of two complementary angles is 90°.

According to the given question angle M and angle N are complementary.

∴ Sum of these two angles ∠M + ∠N = 90°.

Assuming measure of ∠N to be x°,So the measure of ∠M is (x-38)°.

Therefore, x + (x-38) = 90°.

2x = 90° + 38°

2x = 128°.

x = 64°.

∴ The measure of ∠M is (64 - 38 )° = 26°.

Answer:

Step-by-step explanation:

The dot product of two vectors u and v is given by the formula:

u · v = u[0] * v[0] + u[1] * v[1] + u[2] * v[2]

where u[0], u[1], and u[2] are the components of vector u and v[0], v[1], and v[2] are the components of vector v.

Plugging in the values from the vectors u = [2, 3, 4] and v = [5, 6, 7], we get:

u · v = 2 * 5 + 3 * 6 + 4 * 7 = 10 + 18 + 28 = 56

Therefore, the dot product of the vectors u and v is 56.

The possible values of the solutions to the inequality 5x + 5 ≥ −9 are: I, II, and III.

To find the possible values of the solution to a given inequality, solve the inequality given using the properties of equality to isolate the variable.

Given the inequality:

5x + 5 ≥ −9

Subtract 5 from both sides:

5x + 5 - 5 ≥ −9 - 5 [subtraction property of inequality]

5x ≥ -14

Divide both sides by 5

5x/5 ≥ -14/5

x ≥ -2.8

Step-by-step explanation:

Note that based on probabilities,

The expected number of Democrats on the committee is 5.

The expected number of states represented on the committee is 26.

The expected number of states such that both of the state's senators are on the committee is 9.09.

a)  The probability that a randomly chosen senator is a Democrat is 50/100 = 1/2.

So, the expected number of Democrats on a committee of size 10 is

1/2 * 10 = 5.

b) The minimum number of   states that can be represented on a committee of size 10 is 2, and the maximum numberis 50.

The expected number of states representedon the committee is the average of these two values, which is (2 + 50)/  2 = 26.

c)  There are 50 states, and each state has 2 senators. So, there are a total of 100 pairs of senators.

The probability that a randomly chosen pair of senators both belong to the same state is 50/100 * 49/99

= 1/11.

The expected number of states such that both of the state's senators are on the committee is 100 * 1/11 = 9.09.

Answer:

16

Step-by-step explanation:

We can use the binomial distribution formula to find the probability of flipping three coins tails, four coins tails, and five coins tails. This is because the probability of P(x=3) is going to give the same result if we had defined the entire set, counted how many had 3, and then divided that by the entire set. So we can use this to find how much % of the data set is going to have at least 3.

So the binomial distribution formula is defined as: \(P_x=(^n_x)p^x(1-p)^{n-x}\), where n=number of trials, x=how many successes (in this case it will be 3, 4, and 5) and p=probability of success.

The binomial coefficient is defined as: \((^n_x)=\frac{n!}{k!(n-x)!}\).

So let's define the variables.

x = 3, 4, 5 since we want to find the probability of getting at least 3. This means we want the probability of getting 3, 4, or 5 tails, and then we simply add up these probabilities.

n = 5, since Paul is flipping the coin 5 times

p = 0.5 since the probability of flipping tails is 0.50

So let's plug the information in!

\(P_{x\ge3} = P_3 + P_4 + P_5\)

\(P_3=\frac{5!}{3!2!}*0.5^30.5^2 = 0.3125\)

\(P_4=\frac{5!}{4!1!}*0.5^4*0.5^1=0.15625\)

\(P_5 = \frac{5!}{5!0!}0.5^50.5^0 = 0.03125\)

Now let's add up all these probabilities to get:

\(0.3125 + 0.15625 + 0.03125 = 0.5\)

This means 50% of the time Paul will flip three or more tails.

To translate this to the number of ways, we need to find how many combinations there are which can generally be defined as: \(options^{length}\) and in this case options = tails and heads so 2, and the length is 5. So we get: \(2^5 = 32\)

Now multiply the 32 by the 0.5 and you get 16, which is the amount of ways he can flip at least three tails

The value of the union of sets A and B is, P(A ∪ B) is 0.64.

The union of two sets means the total elements in both the sets combined.

Given: sets P(A) = 0.38, P(B) = 0.83, and  intersection P(A ∩ B) = 0.57

We need to find the union of P(A ∪ B).

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

Let us substitute the given values in the formula.

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

=0.38+0.83-0.57
