The required value of x is 22 degrees for the given figure.
Adjacent angles are a sort of additional angle. Adjacent angles share a common side and vertex, such as a corner point. Their points do not overlap in any manner.
As we know that supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.:
According to the given figure, it can be written as follows:
2x + 24 + 6x - 20 = 180
8x + 4 = 180
8x = 180 - 4
8x = 176
x = 176/8
x = 22
Therefore, the required value of x is 22 degrees for the given figure.

36% of the tarts that a baker baked were strawberry tarts. He baked 98 more chocolate tarts than strawberry tarts. How many tarts did the baker bake in all?
Answer:
350
Step-by-step explanation:
100% - 36% = 64% (we first find out the remaining percentage)
Now we know there are 98 more chocolate tarts than strawberry tarts. We have to find out that percentage.
So, 64% - 36% = 28%
So 98 of the chocolate tarts make up 28%
x --------> 100%
98 --------> 28%
Just follow the percentage formula.
98 * 100 = 9800
9800/28 = 350
If A is an 8 times 6 matrix, what is the largest possible rank of A? If A is a 6 times 8 matrix, what is the largest possible rank of A? Explain your answers. Select the correct choice below and fill in the answer box(es) to complete your choice. A. The rank of A is equal to the number of pivot positions in A. Since there are only 6 columns in an 8 times 6 matrix, and there are only 6 rows in a 6 times 8 matrix, there can be at most pivot positions for either matrix. Therefore, the largest possible rank of either matrix is B. The rank of A is equal to the number of non-pivot columns in A. Since there are more rows than columns in an 8 times 6 matrix, the rank of an 8 times 6 matrix must be equal to. Since there are 6 rows in a 6 times 8 matrix, there are a maximum of 6 pivot positions in A. Thus, there are 2 non-pivot columns. Therefore, the largest possible rank of a 6 times 8 matrix is C. The rank of A is equal to the number of columns of A. Since there are 6 columns in an 8 times 6 matrix, the largest possible rank of an 8 times 6 matrix is. Since there are 8 columns in a 6 times 8 matrix, the largest possible rank of a 6 times 8 matrix is.
The correct answer is B
The rank of A is equal to the number of non-pivot columns in A. Since there are more rows than columns in an 8 times 6 matrix, the rank of an 8 times 6 matrix must be equal to the number of pivot positions, which is 6. Since there are 6 rows in a 6 times 8 matrix, there are a maximum of 6 pivot positions in A. Thus, there are 2 non-pivot columns. Therefore, the largest possible rank of a 6 times 8 matrix is 2.

Step-by-step explanation:
A statistics teacher started class one day by drawing the names of 10 students out of a hat and asked them to do as many pushups as they could. The 10 randomly selected students averaged 15 pushups per person with a standard deviation of 9 pushups. Suppose the distribution of the population of number of pushups that can be done is approximately normal. The 95% confidence interval for the true mean number of pushups that can be done is _____.
Using the t-distribution, we have that the 95% confidence interval for the true mean number of pushups that can be done is (9, 21).
For this problem, we have the standard deviation for the sample, thus, the t-distribution is used.
The sample mean is of 15, thus \(\overline{x} = 15\).The sample standard deviation is of 9, thus \(s = 9\).The sample size is of 10, thus \(n = 10\).First, we find the number of degrees of freedom, which is the one less than the sample size, thus df = 9.
Then, looking at the t-table or using a calculator, we find the critical value for a 95% confidence interval, with 9 df, thus t = 2.2622.
The margin of error is of:
\(M = t\frac{s}{n}\)
Then:
\(M = 2.2622\frac{9}{\sqrt{10}} = 6\)
The confidence interval is:
\(\overline{x} \pm M\)
Then
\(\overline{x} - M = 15 - 6 = 9\)
\(\overline{x} + M = 15 + 6 = 21\)
The confidence interval is (9, 21).

Shonda has $125. She spends 35% of the money she has on a concert ticket. How much did Shonda spend on the ticket?
Answer:
she spent $43.75
Step-by-step explanation:
you basically need 35% of $125
cool trick with this is "of" always means multiplication
35% x 125= 43.75
she spent $43.75
Shonda spent the amount of $43.75 on the concert ticket.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
To find out how much Shonda spent on the concert ticket, we can use the following proportion:
(35%) × 125 = x/1
where x is the amount of money spent on the concert ticket, and we know that 35/100 (or 0.35) is 35% of 125.
Convert percent into decimal form and solve for x:
(0.35) × 125 = x
Apply the multiplication operation, and we get
x = 43.475
Therefore, she spent $43.75 on the concert ticket.

Answer:
m∠LKJ = 40°----------------------------
Angle formed by the chord and tangent is half the measure of the intercepted arc:
m∠LKJ = (1/2) mKJm∠LKJ = (1/2) (80°)m∠LKJ = 40°When a buffet restaurant charges $12.00 per meal, the number of meals it sells per day is 400 .For each $0.50 increase to the price per meal, the number of meals sold per day decreases by 10 . What is the price per meal that results in the greatest sales, in dollars, from meals each day.
We can estimate that the price per meal that results in the greatest sales, in dollars, from meals each day is around $12.75 to $13.00. This is based on the observation that the revenue increases with each $0.50 increase in price per meal, but the increase in revenue gets smaller with each increase.
To determine the price per meal that results in the greatest sales, we need to find the point where the revenue is highest.
Let's start by calculating the revenue at $12.00 per meal:
Revenue = Price per meal x Number of meals sold
Revenue = $12.00 x 400
Revenue = $4,800
Now let's increase the price per meal by $0.50 and decrease the number of meals sold by 10:
Revenue = (Price per meal + $0.50) x (Number of meals sold - 10)
Revenue = ($12.50) x (390)
Revenue = $4,875
We can see that the revenue has increased by $75.00.
Let's continue this process by increasing the price per meal by another $0.50 and decreasing the number of meals sold by another 10:
Revenue = ($13.00) x (380)
Revenue = $4,940
Again, the revenue has increased by $65.00.
We can continue this process until the revenue starts to decrease. However, we can also see that the increase in revenue is getting smaller with each $0.50 increase in price per meal.
Therefore, we can estimate that the price per meal that results in the greatest sales is likely to be somewhere between $12.50 and $13.00.
To get a more precise answer, we can use calculus to find the maximum point of the revenue function. But without doing that, we can estimate that the price per meal that results in the greatest sales is around $12.75 to $13.00.

To find the meal price that will result in the greatest daily sales, construct an equation for net income, which is the product of price per meal and meals sold per day. The differential equation of this profit function then needs to be solved to find the price that maximizes revenue.
Explanation:The subject is a classic application of linear functions in Finance. Here, we are trying to maximize the revenue, which is the product of price per meal and number of meals sold per day.
Let's denote the increase in the initial price, $12.00, by increments of $0.50 as 'x'. Therefore, the new price is 12 + 0.5x. Correspondingly, the number of meals sold decreases by 10 units per increment, i.e., 400 - 10x meals.
The revenue becomes R = (12 + 0.5x) * (400 - 10x). To find the price per meal that maximizes revenue, differentiate R with respect to x and set it to zero, solving for x. Plugging the value of x in the price equation will give the optimal price per meal.

state whether the data described below are discrete or continuous, and explain why. the number of televisions in differenet households
The data described, the number of televisions in different households, is discrete.
discrete data consists of individual values that can be counted and are distinct from one another. In this case, the number of televisions is a discrete variable because it can only take on whole numbers, such as 0, 1, 2, 3, and so on. You cannot have a fractional or continuous number of televisions. Each household will have a specific count of televisions, and there is no intermediate value between each whole number. Additionally, the number of televisions is distinct for each household, meaning that it can differ from one household to another.

an elevator starts at floor 3. it goes ip 4 floors twice and it goes down 4 floors. a second elevator starts on floor 19. it goes down 1 time and goes up 7 floors. which elevator ends on a higher floor?
Comparing the final positions of the two elevators, the second elevator ends on a higher floor, at floor 25, while the first elevator ends on floor 7. We need to compare the final floors of both elevators.
For the first elevator, it starts at floor 3 and goes up 4 floors twice, which brings it to floor 3 + (4x2) = 11. Then it goes down 4 floors, which brings it to floor 11 - 4 = 7.
For the second elevator, it starts at floor 19 and goes down 1 floor, which brings it to floor 19 - 1 = 18. Then it goes up 7 floors, which brings it to floor 18 + 7 = 25.
Therefore, the second elevator ends on a higher floor than the first elevator.
The first elevator ends on floor 7, while the second elevator ends on floor 25. This comparison was made by analyzing the number of floors each elevator went up or down from their starting positions. The first elevator starts on floor 3, goes up 4 floors twice, and then goes down 4 floors. After going up 4 floors once, it is on floor 7 (3+4). Going up another 4 floors puts it on floor 11 (7+4). Finally, going down 4 floors places it on floor 7 (11-4). The second elevator starts on floor 19, goes down 1 floor, and then goes up 7 floors. After going down 1 floor, it is on floor 18 (19-1). Going up 7 floors puts it on floor 25 (18+7).

events a and b are mutually exclusive with p(a) = .3 and p(b) = .2. the probability of the complement of event b equals _____.
The probability of the complement of event B is 0.8, or 80%.
The complement of an event A, denoted as A', represents all outcomes that are not in event A. Similarly, the complement of an event B, denoted as B', represents all outcomes that are not in event B. Since events A and B are mutually exclusive, they cannot occur simultaneously. Therefore, the probability of the complement of event B, P(B'), can be calculated by subtracting the probability of event B, P(B), from 1.
Since P(B) = 0.2, the probability of the complement of event B is:
P(B') = 1 - P(B) = 1 - 0.2 = 0.8.

fill in the blank. a regression line is also called the ______. group of answer choices line of estimate scatterplot line line of best fit line graph
The correct answer is "line of best fit." A regression line is also called the line of best fit as it represents the best approximation of the relationship between the independent and dependent variables in a scatterplot.
What is regression line?In statistics and data analysis, a regression line is a straight line that represents the best-fitting relationship between two variables. It is often referred to as the "line of best fit" because it minimizes the overall distance between the line and the actual data points.
When plotting data points on a scatterplot, the regression line is used to approximate the trend or pattern in the data. It helps in understanding the relationship between the independent variable (usually denoted as "x") and the dependent variable (usually denoted as "y"). The goal is to find a line that is as close as possible to all the data points, capturing the general trend or direction of the relationship.
The line of best fit is determined by using a statistical technique called regression analysis. This technique calculates the optimal values for the slope and intercept of the line based on the data. The most common method for fitting a regression line is known as ordinary least squares (OLS), which minimizes the sum of the squared differences between the observed data points and the predicted values on the line.
By fitting a regression line, we can make predictions or estimations about the dependent variable based on the values of the independent variable. The line of best fit provides a visual representation of the relationship between the variables and allows for easier interpretation and analysis of the data.
It's important to note that the line of best fit is an estimation based on the given data, and it may not perfectly pass through every data point. However, it provides a useful summary of the overall trend and can be used for making predictions or drawing conclusions about the relationship between the variables.
Therefore, the correct answer is "line of best fit." A regression line is also called the line of best fit as it represents the best approximation of the relationship between the independent and dependent variables in a scatterplot.

A candle is formed in the shape of a cylinder. It has a diameter of 4 inches a d a height if 5 inches. Which measurement is closest to the total surface area of the candle in square inches
The closest measurement in square inches to the overall surface area of the candle is 87.92 square inches.
To find the total surface area of the candle, we need to calculate the lateral surface area (excluding the top and bottom) and then add the areas of the two circular bases.
1. Lateral Surface Area:
The formula for the lateral surface area of a cylinder is given by A = 2πrh, where r is the radius of the base and h is the height of the cylinder.
Given that the diameter of the candle is 4 inches, we can calculate the radius by dividing the diameter by 2:
Radius (r) = 4 inches / 2 = 2 inches
Height (h) = 5 inches
Using the formula, we can calculate the lateral surface area:
Lateral Surface Area = 2π(2 inches)(5 inches) = 20π square inches
2. Base Area:
The formula for the area of a circle is given by A = πr^2, where r is the radius of the circle.
Using the radius calculated earlier (r = 2 inches), we can calculate the area of each circular base:
Base Area = π(2 inches)^2 = 4π square inches
3. Total Surface Area:
To find the total surface area, we add the lateral surface area and the areas of the two circular bases:
Total Surface Area = Lateral Surface Area + 2(Base Area)
Total Surface Area = 20π + 2(4π) = 20π + 8π = 28π square inches
Approximating the value of π to 3.14, we can calculate the approximate total surface area:
Total Surface Area ≈ 28(3.14) = 87.92 square inches
Therefore, the closest measurement to the total surface area of the candle in square inches is 87.92 square inches.
