Answer:
If the distance from the origin to a given point is 5, then that point lies on circle C is true.
Step-by-step explanation:
The correct statement about given circle is "If the distance from the origin to a given point is 5, then that point lies on circle C"
What is a circle?In mathematics, the circle is a two dimensional rounded figure which has no corner edges.
Standard form = (x - a)² + (y - b)² = r²
Given that,
The center of a circle is on origin and the radius is 5 unit.
And point p lies on the circle,
So, according to definition of circle the distance between center and any point on the circle is always constant and which is known as radius.
Therefore, the distance between center end given point will be equal to 5 then it will lies on a circle.

A chart that is recommended as an alternative to a pie chart is a - stacked column chart. A chart that is recommended as an alternative to a pie chart is a stacked column chart. Question 24: A data visualization tool that updates in real time and gives multiple outputs is called - a data dashboard.
A data visualization tool that updates in real time and gives multiple outputs is called a data dashboard. What is a scatter plot? A scatter plot is a type of diagram used to display two variables on a two-dimensional plot. The positioning of data points on a scatter plot graphically depicts the correlation between the two variables. To construct a scatter plot, two variables (independent and dependent variables) are plotted on a graph.
The independent variable is plotted on the horizontal (x) axis and the dependent variable is plotted on the vertical (y) axis. A point is plotted for each pair of values, and the pattern of the points suggests a relationship between the two variables.A scatter plot is useful in displaying the correlation between two variables. The correlation is positive if the points are in an upward direction. The correlation is negative if the points are in a downward direction. A lack of correlation, or random points, is suggested by a scatter plot with no apparent pattern.

Dr. Silas studies a culture of bacteria under a microscope. The function b1 (t) = 1200 (1. 8)^t represents the number of bacteria t hours after Dr. Silas begins her study.
(a) What does the value 1. 8 represent in this situation?
(b) The number of bacteria in a second study is modeled by the function b2 (t) = 1000 (1. 8)^t.
What does the value of 1000 represent in this situation?
What does the difference of 1200 and 1000 mean between the two studies?
The difference of 1200 and 1000 between the two studies means that the second study had 200 more bacteria than the first one.
In the first study, the number of bacteria is modeled by the function b1(t) = 1200(1.5)^t, while in the second study, the number of bacteria is modeled by the function b2(t) = 1000(1.8)^t. The difference of 1200 and 1000 is the initial number of bacteria in the first study, which is 200 more than the second study.
Both studies model the growth of bacteria over time. In the first study, the growth rate is 1.5, while in the second study, it is 1.8. The difference between the two studies can be explained by the difference in the growth rates. A growth rate of 1.8 means that the bacteria will multiply faster than a growth rate of 1.5, resulting in a higher number of bacteria in the second study. However, the initial number of bacteria in the second study was lower than in the first study, resulting in a lower total number of bacteria despite the higher growth rate.

According to a recent survey, the averaga daly rain for a luxury hetel is $ 233.49 . Assume the daly rate follows a normal probobily dithbuton wen a standard devation of $ 21 . 72 . Compie
The z-score for a daily rate of $233.49 with a standard deviation of $21.72 is approximately 0.1440.
To calculate the z-score, we use the formula:
z = (x - μ) / σ
Where:
z = z-score
x = observed value
μ = mean
σ = standard deviation
In this case, the observed value (x) is $233.49, the mean (μ) is the average daily rate, and the standard deviation (σ) is $21.72.
Using the formula, we can calculate the z-score:
z = (233.49 - μ) / 21.72
Since we are given the average daily rate as $233.49, the z-score is:
z = (233.49 - 233.49) / 21.72 = 0 / 21.72 = 0
Therefore, the z-score for a daily rate of $233.49 with a standard deviation of $21.72 is 0.
The z-score for a daily rate of $233.49 with a standard deviation of $21.72 is 0. This indicates that the observed value is equal to the mean, suggesting that the daily rate falls in line with the average for a luxury hotel.

how is the variable manufacturing overhead efficiency variance calculated?
Variable Manufacturing Overhead Efficiency can be calculated by comparing the standard cost of actual production at the standard number of hours required to produce the actual output, which is multiplied by the standard variable overhead rate per hour, with the actual variable overhead cost incurred in producing the actual output.
Variance is calculated by comparing the standard cost of actual production at the standard number of hours required to produce the actual output, which is multiplied by the standard variable overhead rate per hour, with the actual variable overhead cost incurred in producing the actual output.
The following formula can be used to calculate the Variable Manufacturing Overhead Efficiency Variance:
Variable Manufacturing Overhead Efficiency
Variance = (Standard Hours for Actual Output x Standard Variable Overhead Rate) - Actual Variable Overhead Cost
Where,
Standard Hours for Actual Output = Standard time required to produce the actual output at the standard variable overhead rate per hour
Standard Variable Overhead Rate = Budgeted Variable Manufacturing Overhead / Budgeted Hours
Actual Variable Overhead Cost = Actual Hours x Actual Variable Overhead Rate
The above formula can also be represented as follows:
Variable Manufacturing Overhead Efficiency Variance = (Standard Hours for Actual Output - Actual Hours) x Standard Variable Overhead Rate
Therefore, the Variable Manufacturing Overhead Efficiency Variance can be calculated by comparing the standard cost of actual production at the standard number of hours required to produce the actual output, which is multiplied by the standard variable overhead rate per hour, with the actual variable overhead cost incurred in producing the actual output.

A 12 1/4 -inch candle burns down in 7 hours. Assuming the candles are the same thickness and make (that is, directly proportional), how long would it take a 7-inch candle to burn down?
7 inch length of candle will burn in 4 hours
In the above question, it is given that
A candle burns down as follows
The length of candle burn in 4 hours = 12 \(\frac{1}{4}\) inch
Converting it from mixed fraction to fraction we get
= \(\frac{49}{4}\)inch
We need to find a 7 inch length of candle will burn in how many hours
To find that, first we'll calculate 1 inch candle is burning in what time
\(\frac{49}{4}\)inch is burning in = 7 hours
1 inch is burning in = \(\frac{7}{\frac{49}{4} }\)
= \(\frac{7 . 4}{49}\) = \(\frac{28}{49}\) = \(\frac{4}{7}\) hrs

Answer:
m∠B < m∠A < m∠C
Step-by-step explanation:
We can work with the triangle inequality to find that the side measures form a triangle when n > 5/4. For the given value of n ≥ 4, we don't need to be concerned with whether a triangle is formed or not.
For n = 4, the side lengths are ...
a = 2(4) = 8
b = (4) +3 = 7
c = 3(4) -2 = 10
The longest side is opposite the largest angle, so the ordering of angles is ...
m∠B < m∠A < m∠C

The triangle inequality requires all of these inequalities be true:

Answer:
Steps to find the equation of a line from two points:
Find the slope using the slope formula
Use the slope and one of the points to solve for the y-intercept (b).
One of your points can replace the x and y, and the slope you just calculated replaces the m of your equation y = mx + b. Then b is the only variable left. Use the tools you know for solving for a variable to solve for b.
Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.
