Lola used 15/4 cups of rice to make rice pudding.

Given is that Lola has 4[tex]\frac{1}{2}[/tex] cups of rice. She uses 3/4 of the rice to make sushi rolls for dinner. She uses the rest of the rice to make rice pudding for dessert.

Amount used by Lola for the rice pudding -

{x} = 4[tex]\frac{1}{2}[/tex] - 3/4

{x} = 9/2 - 3/4

{x} = 18/4 - 3/4

To keep his blackmailers at bay for 12 months, the Grand Vizier needs to balance the number of gold payoffs and political favors he gives to them. Let's represent the number of gold payoffs by G and the number of political favors by P.

From the given information, we have:

Each gold payoff gives him an average of 1 month of reprieve.

Each political favor gives him an average of 1.5 months of reprieve.

He cannot afford any revelations about his past to come to light within the next year, which means he needs to keep his blackmailers at bay for 12 months.

He wants to keep the number of gold payoffs at no more than one-quarter of the combined number of payoffs.

He can do no more than seven political favors per year.

Each gold bar removed from the treasury will cost him four trips.

Each political favor will cost him about two trips.

Let's first calculate the maximum number of political favors he can give in a year:

7 political favors per year

Next, let's find the maximum number of payoffs he can give in a year:

G + P = total number of payoffs

G ≤ 0.25(G+P) (to keep the number of gold payoffs at no more than one-quarter of the combined number of payoffs)

Simplifying the second equation, we get:

G ≤ 0.25G + 0.25P

0.75G ≤ 0.25P

3G ≤ P (multiplying both sides by 3)

So the maximum number of payoffs he can give in a year is 7 + G, where G ≤ 3.

Next, we need to find the combination of payoffs that will give him the most reprieve while losing the fewest trips. We can use a table to calculate the reprieve and trip costs for different combinations of payoffs: look at the table

From the table, we see that the best combination is G=3 and P=4, which will give him a total reprieve of 12 months (the required time) while costing him 26 trips (the minimum possible). Therefore, the Grand Vizier will lose 26 trips in the next year.

The perimeter of the rectangular bedroom is: A. 116 feet.

Perimeter of a rectangle = 2(length + width)

To find the perimeter of the rectangular bedroom, we need to calculate the sum of the lengths of its four sides.

Let's start by finding the length of the horizontal sides of the rectangle. The two horizontal sides are defined by the points (21, 18) and (21, −7), which are 25 feet apart in the vertical direction (18 − (−7) = 25). Therefore, the length of each horizontal side is 25 feet.

Next, let's find the length of the vertical sides of the rectangle. The two vertical sides are defined by the points (21, 18) and (−12, 18), which are 33 feet apart in the horizontal direction (21 − (−12) = 33). Therefore, the length of each vertical side is 33 feet.

Now we can add up the four side lengths to get the perimeter:

Perimeter = 2(Length of horizontal sides) + 2(Length of vertical sides)

= 2(25 feet) + 2(33 feet)

= 50 feet + 66 feet

The required probability that events A and B both occur is 0.15.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

The probability that events A and B both occur is given by the product of their individual probabilities if they are independent. Independence means that the occurrence of one event does not affect the probability of the other event.

In this case, the probability that events A and B both occur is given by:

0.3 × 0.5 = 0.15

So, the probability that events A and B both occur is 0.15.

It's important to note that without further information, we cannot determine if events A and B are independent. The probabilities of 0.3 and 0.5 are the individual probabilities of each event, but we would need to know if their occurrence affects each other to determine if they are independent.

Answer: The commutative property of addition states that changing the order of the terms being added does not change the sum. Therefore, we can rearrange the terms in an expression in any order we choose without changing the result.

For example, if we have the expression:

3x + 2y + 4x + 5y

We can use the commutative property of addition to rearrange the terms as:

3x + 4x + 2y + 5y

Then, we can collect the like terms (terms with the same variable and exponent) by combining the coefficients:

7x + 7y

So the simplified expression is 7x + 7y.

Step-by-step explanation:

The statement of option a "for data sets with different measurement units" and the statement of option b "for data sets with the same measurement units but greatly different magnitudes." is true about comparing standard deviations. So the option a and b is correct.

When comparing standard deviations, it is important to consider the context in which the data was collected. For example, if two datasets have similar means but different standard deviations, the one with the larger standard deviation may indicate more variability or a wider range of values.

On the other hand, if two datasets have different means but similar standard deviations, the one with the larger mean may be more representative of the population as a whole. In either case, it is important to look at the context of the data to make a more informed comparison.

2: x = -1 + (2/2)(x + y), y = -1 + (2/2)(-x + y)

The first linear mapping can be found by using the following matrix:

M = [a b]

   [c d]

where, a = 2/2, b = -1, c = -2/2, d = 1.

By multiplying the matrix M with the vector [x, y]T, the linear mapping can be obtained.

For example, for the point (0, 1):

M * [0, 1]T = [-1, 1]

Similarly, for the point (1 + i, i):

M * [1 + i, i]T = [-1 + i, -1 + i]

Therefore, we get the linear mapping:

x = -1 + (2/2)(x + iy), y = -1 + (2/2)(x - iy)

The second linear mapping can be found by using the following matrix:

N = [e f]

   [g h]

Calculate the value of x of the small right-angle triangle.

Two out of the three given existential quantifications are true, while one is false.

In mathematics, quantifiers are used to describe the properties of a set or a domain. One such quantifier is the existential quantifier, which is used to indicate the existence of at least one element in a set that satisfies a given property. In this case, we are interested in finding out which of the given existential quantifications are true, where the domain of x is restricted to positive integers. Let's explore this in more detail.

The domain of x is the set of positive integers, which means that x can only take on values such as 1, 2, 3, 4, and so on. The given existential quantifications are as follows:

∃x(x²=9)

∃x(x+3=5)

∃x(x²=2)

Let's examine each of these in turn.

∃x(x²=9)

This existential quantification is true. To see why, we need to find an integer value of x such that x² equals 9. We can easily see that x=3 satisfies this property, since 3² = 9. As 3 is an integer and satisfies the condition, the statement is true.

∃x(x+3=5)

This existential quantification is also true. We need to find an integer value of x such that x+3 equals 5. This can be easily done by subtracting 3 from both sides of the equation to get x=2. As 2 is an integer and satisfies the condition, the statement is true.

∃x(x²=2)

This existential quantification is false. We need to find an integer value of x such that x² equals 2. However, there is no such integer value of x. This can be proven using the fact that the square of any integer is always a non-negative integer. Therefore, the statement is false.

We would expect an ace to be drawn about 32 times out of 200 draws based on Eli's experiment.

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Given, A small deck of cards has 4 kings, 3 queens, 2 jacks, and 1 ace.

To determine the expected number of times an ace would be drawn out of 200 draws, we need to use the probability of drawing an ace and multiply it by the total number of draws.

The probability of drawing an ace is the number of aces divided by the total number of cards:

Probability of drawing an ace = (12) / (75)

= 4/25

Therefore, the expected number of times an ace would be drawn out of 200 draws is:

Expected number of aces = Probability of drawing an ace x Total number of draws
