Understanding the truth values and logic behind these statements is important to correctly determine their validity. The questions that are True are B and D, and the questions that are A, C, and E.

a. False. In a conditional statement, if the antecedent (the "if" part) is false, the truth value of the conditional statement depends on the truth value of the consequent (the "then" part). If the consequent is true, the conditional statement is true, but if the consequent is false, the conditional statement is false.

b. True. In a disjunction (logical OR), if at least one of the disjuncts is true, then the entire disjunction is true. It only takes one true statement for the disjunction to be true.

c. False. Similar to statement a, if the consequent of a conditional statement is false, the truth value of the conditional statement depends on the truth value of the antecedent. If the antecedent is true, the conditional statement is true, but if the antecedent is false, the conditional statement is false.

d. True. In a conjunction (logical AND), for the entire conjunction to be true, all conjuncts must be true. If one conjunct is true, it guarantees that the conjunction will be true.

e. False. In a conjunction (logical AND), if at least one conjunct is false, the entire conjunction is false. All conjuncts must be true for the conjunction to be true. If any conjunct is false, the conjunction will be false.

Therefore, it's important to understand the truth values and logic behind these statements to correctly determine their validity.

Here is a paragraph about the transformations I used to create my logo.

I started with a basic shape, a square. I then reflected the square across the horizontal axis, creating a mirror image. I then translated the reflected square up and to the right, creating a new shape. I then rotated the new shape 45 degrees, creating a third shape. The third shape is symmetric, meaning that it can be divided into two identical halves.

I then used these three shapes to create my logo. I used the first shape as the background, the second shape as the foreground, and the third shape as the logotype. I chose these shapes because they represent the three stages of transformation: the beginning, the middle, and the end.

The reflection represents the beginning of the transformation, when something is changed from its original state.

The probability that exactly 12 out of 22 pitches are strikes is approximately 0.18 (rounded to two decimal places).

To find the probability that exactly 12 out of 22 pitches are strikes, we can use the binomial probability formula. In this case, the probability of throwing a strike for each pitch is 0.431, and we want to calculate the probability of getting exactly 12 strikes out of 22 pitches.

Using the binomial probability formula, the probability of getting exactly 12 strikes out of 22 pitches is:

P(X = 12) = C(22, 12) * (0.431)^12 * (1 - 0.431)^(22 - 12)

where C(22, 12) represents the number of ways to choose 12 strikes out of 22 pitches.

Calculating this probability, we find:

P(X = 12) = 22! / (12! * (22 - 12)!) * (0.431)^12 * (1 - 0.431)^(22 - 12)

Answer:

£200

Step-by-step explanation:

To determine how many pounds Jenny got back, we first need to calculate the exchange rate between pounds (£) and dollars ($).

Jenny initially changed £480 into $744, so £480 = $744.

To find the exchange rate in terms of pounds (£) to dollars ($), divide both quantities by 480:

[tex]\dfrac{480}{480}=\dfrac{744}{480}[/tex]

[tex]\£1=\$1.55[/tex]

Therefore, the exchange rate was £1 = $1.55.  

This means that for every £1 Jenny exchanged, she received $1.55.

To convert the $310 Jenny had left back into pounds (£), divide the dollar amount by 1.55:

[tex]\dfrac{310}{1.55}=200[/tex]

Therefore, if the exchange rate stayed the same, Jenny got back £200.

Kevin's boss has indicated that there should be at least 2 inches of space between the top of the pasta and the top of the box. This indicates that the maximum capacity of the box will be reduced by this amount.The volume of the pasta box can be calculated as the product of the height and the area of the base. Here's how:Volume of the box = Height × Area of the base Given that the height of the box is 9 inches and the area of the base is 9 square inches.

Thus, the volume of the box is:V = Height × Area of the baseV = 9 × 9V = 81 cubic inchesHowever, the boss has said that at least 2 inches of space must be left between the top of the pasta and the top of the box. This implies that the pasta must occupy a volume that is less than or equal to 81 − 2 = 79 cubic inches.Therefore, the pasta will fit into the new box with enough space at the top since 79 cubic inches are greater than or equal to the volume of pasta in the box.

To find the three numbers, we need to use the information given about their mean, median, and range. Since the median is 18, we know that the middle number of the three must be 18. Also, since the mean is 20, the sum of the three numbers must be 3 times 20, which is 60. So, the 3 numbers are 16, 18, and 26.

Let's call the smallest number x, then the largest number must be x+10 since the range is 10.
Now we can set up an equation to solve for x. We know that the sum of the three numbers is 60, so we can write:
x + 18 + (x+10) = 60
Simplifying this equation gives:
2x + 28 = 60
Subtracting 28 from both sides gives:
2x = 32
Dividing by 2 gives:
x = 16

Therefore, the three numbers are 16, 18, and 26.
Given the information provided, we know the following:
1. Mean of 3 numbers is 20.
2. Median of the 3 numbers is 18.
3. Range (largest - smallest) is 10.
Since there are 3 numbers and the median is 18, the middle number is 18. Let's call the smallest number "x" and the largest number "y". We can now write two equations:
1. (x + 18 + y) / 3 = 20
2. y - x = 10
We can simplify the first equation to find the sum of the 3 numbers:
x + 18 + y = 60
Now, we can solve for x in the second equation:
x = y - 10
Substituting the value of x in the first equation:
(y - 10) + 18 + y = 60
Solving for y:
2y = 52
y = 26
Now, we can find the value of x:
x = 26 - 10
x = 16
So, the 3 numbers are 16, 18, and 26.

The perimeter of the rhombus is 4√117 feet.

What is rhombus?

A rhombus is a special type of quadrilateral (a polygon with four sides) where all four sides are equal in length. It is also known as a diamond shape because of its symmetrical appearance.

In a rhombus, the diagonals are perpendicular bisectors of each other. This means that they divide the rhombus into four congruent right triangles.

Let's denote the length of one diagonal as d1 and the length of the other diagonal as d2. In this case, d1 = 18 feet and d2 = 12 feet.

Each right triangle formed by the diagonals has legs equal to half the lengths of the diagonals. Therefore, the lengths of the legs are d1/2 = 18/2 = 9 feet and d2/2 = 12/2 = 6 feet.

Using the Pythagorean theorem, we can find the length of the hypotenuse of each right triangle, which is also a side of the rhombus.

[tex]h^2 = (leg1)^2 + (leg2)^2\\\\h^2 = 9^2 + 6^2\\\\h^2 = 81 + 36\\\\h^2 = 117[/tex]

Taking the square root of both sides:

h = √117

Since the rhombus has four congruent sides, the perimeter is given by:

Perimeter = 4 * h = 4 * √117

The correct answer is Pelicans. they have a larger mean value of about 22.5 inches.To determine which team has the largest overall size hat for their players, we can compare the measures of center for the two teams. The measures of center commonly used are the median and the mean.

To find the median, we arrange the hat sizes in ascending order and find the middle value. For the Pelicans, when we arrange their hat sizes in ascending order, we get:

21 21.5 22 22 22.5 23 23.5 24 24.5

The median is the middle value, which is 22.5 inches

.For the Falcons, when we arrange their hat sizes in ascending order, we get:

20 20.5 21 21.5 22 22.5 23 23.5 24 24.5

The median is also 22.5 inches.

Since both teams have the same median value, we need to compare the mean. To find the mean, we sum up all the hat sizes and divide by the total number of measurements.

For the Pelicans, the sum of their hat sizes is 22 + 21 + 22 + 22 + 23.5 + 22 + 23 + 24 + 21.5 + 24.5 = 225 inches.

Dividing by 10 (the number of measurements) gives a mean value of 22.5 inches.

For the Falcons, the sum of their hat sizes is 20 + 20.5 + 21 + 21.5 + 22 + 22.5 + 23 + 23.5 + 24 + 24.5 = 222 inches.Dividing by 10 (the number of measurements) gives a mean value of 22.2 inches.

Malaya: (4 + 5 + 3 + 3 + 5) / 5 = 20 / 5 = 4 laps

Zoe: (7 + 8 + 6 + 8 + 8) / 5 = 37 / 5 = 7.4 laps

Next, we calculate the absolute deviation of each data point from the mean for each friend:

Candice: |5 - 6.2| = 1.2, |6 - 6.2| = 0.2, |8 - 6.2| = 1.8, |5 - 6.2| = 1.2, |7 - 6.2| = 0.8

Malaya: |4 - 4| = 0, |5 - 4| = 1, |3 - 4| = 1, |3 - 4| = 1, |5 - 4| = 1

Zoe: |7 - 7.4| = 0.4, |8 - 7.4| = 0.6, |6 - 7.4| = 1.4, |8 - 7.4| = 0.6, |8 - 7.4| = 0.6

Now, we calculate the MAD for each friend by taking the average of the absolute deviations:

Candice: (1.2 + 0.2 + 1.8 + 1.2 + 0.8) / 5 = 0.6 laps

Malaya: (0 + 1 + 1 + 1 + 1) / 5 = 0.8 laps

Zoe: (0.4 + 0.6 + 1.4 + 0.6 + 0.6) / 5 = 0.72 laps

So,

The given polygon is a pentagon (5 sides).

n = 5

Now,

Total angle.

= (5 -2) x 180

= 3 x 180

= 540

Now,

There are 5 angles that make 540.
