The probability the card is red, given that it is a face card is 1/2 and the probability the card is a king, given that it is a face card is 1/3.
What is probability?
The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a proposition to be true. A number between 0 and 1 is the probability of an event, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.
Given:
A card is drawn from a standard 52-card deck (no jokers).
We have to match each event with its probability.
Since, a deck of cards contains the face cards J, Q, and K.
Let's say there are four different kinds of cards: spades, clubs, hearts, and diamonds.
King, Queen, and Jack are contained in each of these types.
Thus, the total number of face cards is 12 (3 x 4).
(1) Let the face cards are 12 and there are 6 red cards in that 12 face cards.
So, the probability the card is red, given that it is a face card is
= 6/12 = 1/2.
(2) There are 4 king in a 12 face cards.
So, the probability the card is a king, given that it is a face card
= 4/12 = 1/3.
Hence the probability the card is red, given that it is a face card is 1/2 and the probability the card is a king, given that it is a face card is 1/3.

The equation states that the total amount in the savings account will be equal to the initial deposit .The value 1,500 represents the initial amount deposited into the savings account.
The equation A = 1,500 + (1 + 0.06/2)^2t represents the amount of money earned on a compound interest savings account. The value 1,500 represents the initial amount that was deposited into the savings account. The equation states that the total amount in the savings account will be equal to the initial deposit (1,500) plus the amount that is earned by compounding the interest rate on the initial deposit. This is calculated by first adding the initial deposit (1) to the interest rate (0.06/2). This sum is then raised to the power of 2 times the number of years (t) the money has been in the account. This total amount is then added to the initial deposit (1,500) to give the total amount earned on the savings account.

10.1 approximately how many more calories are there in 2 slices of bacon than there are in 3 slices of trasted turkey? why is there a difference?
Therefore, Two slices of bacon had 96 less calories than three slices of roasted turkey.
What does equation mean?a formula that illustrates the connection between two expressions on either side of a sign. It usually only has one variable and an equal sign. like this: 2x – 4 = 2.
Here,
One piece of bacon has 42 calories in it.
There are 60 calories in 1 slice of turkey.
2 slices of bacon are 2 calories each (42)
So 84 calories in 2 slice of bacon
3 slices of roasted turkey have 3 calories each slice (60)
Three slices of roasted turkey have 180 calories each.
180-84 is the difference in the amount of calories.
96 calories are added due to the calorie difference.
Two slices of bacon had 96 less calories than three slices of roasted turkey.

What is linear inequation?
A linear inequation is an equation that contains one or more variables, such as x, and involves linear functions. Unlike a linear equation, its solution set is not a single point, but a range of values. Linear inequations are used to represent situations where the exact value of a variable is not known, but a range of values can be determined based on certain conditions. For example, if x represents the amount of money a person makes in a year and we know that it must be greater than $50,000, then we can write the linear inequation x > 50,000.

A coin is tossed and a die is rolled. These are two independent events. Two events are defined as independent if the outcome of one event has no effect on the outcome of another event. The probability is calculated by multiplying two independent probabilities together, i.e, P(A and B) = P(A) x P(B)
We have, Let us assume two independent events be ,
A : A coin is tossed and the head is thrown.
B : A die is rolled, and a number greater than 5 occurs.
Total possible outcomes when a coin tossed = 2 ={ H ,T }
Total possible outcomes when a die rolled = 6 = { 1,2,3,4,5,6} .

than 5.
Probability of getting the head on toss a coin, P(A) = 1/2
Probability of occuring a number greater than 5 on rolling a die = P(B) = 1/6

What is inequality? What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that Warner received 7 letters and each letter weighed between 3.92 ounces and 4.1 ounces.
If the we take the maximum possible weight of each letter, which is 4 ounces, then the total weight of 7 letters will be equal to (4 x 7) = 28. But since the weights are weighted between 3.92 ounces and 4.1 ounces, let us assume that the weight of each letter is equivalent to -
w(a) = (3.92 + 4.10)/2 = 8.02/2 = 4.01
So, the weight of 7 letters would be -
W{7} = w(a) x 7 = 7 x 4.01 = 28.7
28.7 = 29 (round off) ≈ 30
So, yes the estimate of the Warner is reasonable.

Based on the values you've listed, it appears that the expression P(7, 5) represents a combination calculation. In combinatorics, the notation P(n, k) represents the number of ways to choose a subset of k items from a set of n items, without regard to the order in which the items are chosen. This is also known as the number of k-permutations of n items.
In this case, the expression P(7, 5) would represent the number of ways to choose a subset of 5 items from a set of 7 items. Using the formula for combinations, this would be calculated as follows:
P(7, 5) = 7! / (5! * (7 - 5)!)
= 7! / (5! * 2!)
= 7 * 6 * 5 * 4 * 3 / (5 * 4 * 3 * 2 * 1 * 2 * 1)
= 7 * 6 / 2
= 21
Therefore, the correct answer for the expression P(7, 5) is 21.

Labels on a line graph can make the visualization more accessible in a few ways:
Labels can provide additional context for the data. For example, if the y-axis of the line graph represents the temperature in degrees Celsius, labeling each line with the location or type of temperature measurement can help the viewer better understand the data.Labels can help the viewer more quickly identify the data they are interested in. If the line graph has many lines and a legend, it can be time-consuming to locate the specific line of interest. By labeling each line directly on the graph, the viewer can more easily find the data they are looking for.Labels can improve the clarity and readability of the graph. If the lines on the graph are close together or overlap, labels can help the viewer distinguish between the different lines.Overall, labels can help make a line graph more accessible by providing additional context, improving readability, and helping the viewer quickly find the data they are interested in.

Find the measures of two complementary angles if the measure of the larger angle is 2 less than 3 times the measure of the smaller angle.
Answer:
Let x be the larger angle and y be the smaller angle
Larger angle is 2 less than 3 times the smaller angle that is x = 3y - 2
As the angles are complementary, their sum equals 90°
or, x + y = 90°
or, 3y - 2 + y = 90°
or, 4y = 92°
or, y = 23°
So, x = 3 * 23 - 2 = 67°
Larger angle = x = 67°
Smaller angle = y = 23°
