The most appropriate approach of probability to determine the probability of having a snow on Christmas is Relative frequency approach or Empirical probability.
The Empirical probability, relative frequency, or experimental probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.
The most appropriate approach of probability to determine the probability of getting a red colour if you play on multicolour roulette is Classical approach of probability.
In classical probability, all the outcomes have equal odds of happening. For example, rolling a dice or tossing a coin. The formula of classical probability is as follows: P(A)= f/N; where, P(A)= classical probability, f= frequency or the number of favourable outcomes and N= Number of total possible outcomes.
The most appropriate approach of probability to determine the probability of Catalonia becoming an independent state is Subjective probability.
Subjective probability is a type of probability derived from an individual's personal judgment or own experience about whether a specific outcome is likely to occur. It contains no formal calculations and only reflects the subject's opinions and past experience.
The most appropriate approach of probability to determine the probability of being involved in a car accident is Relative frequency approach or Empirical probability.

Answer:
m∠A = 45°;m∠B = 65°;m∠C = 70°.-----------------------------------
Recall triangle angle sum property, the sum of three interior angles is 180°.
Add up the three angle measures, then solve the equation for x:
m∠A + m∠B + m∠C = 1803(x + 5) + 5x + 15 + 7x = 1803x + 15 + 12x + 15 = 18015x + 30 = 18015x = 150x = 10Substitute the value of x and find the value of each angle:
m∠A = 3(10 + 5) = 3(15) = 45m∠B = 5*10 + 15 = 50 + 15 = 65m∠C = 7*10 = 70What is the equation of the line that passes through the point (-3,1)(−3,1) and has a slope of \frac{2}{3}

Answer:
y = (2/3)x + 3
Step-by-step explanation:
first we need to find the y-intercept
we can do this by using what is given, the point (-3,1) and the slope (2/3)
using the slope-intercept formula: y = mx + b.
m = slope
b = y intercept
we can plug in the x and y values we were given
so,
1 = (2/3)(-3) + b
we can now easily solve for b
1 = (2/3)(-3) = b
first multiply
1 = -2 + b
then add 2 to both sides, this way we isolate b
3 = b
now that we have the y intercept we can write the equation of the line
y = (2/3)x + 3
if you really wanted to, you can check if this is correct by plugging in the point again and seeing if the equation is true.
1 = (2/3)(-3) + 3
multiply first
1 = -2 + 3
add the like terms
1 = 1
In the World of Numbers, there are many number-machines, which work in the following way: the machine adds the two beginning digits of the number and replaces them by their sum. For example, beginning with the number 87312 and using six machines we obtain:
87312-15312-6312-912-102-12-3
How many such machines should be used in order to get to the number 450 from the number 900?
The number of machines used in order to get to the number 450 from the number 900 is 9.
What is an expression?An expression contains more than one term with addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
900 to 450
We need a number of machines such that 450 is the last output starting from 900.
Now,
If we subtract 50 from each consecutive number we get,
900, 850, 800, 750, 700, 650, 600, 550, 500, 450
So,
We use 9 machines to get 450 from 900.
Thus,
9 machines should be used in order to get to the number 450 from the number 900.

PLS HELP! Write 5x = -2y + 6 in slope intercept form and explain your answer
Answer: 5/2x-3
Step-by-step explanation: you would subtract 6 from both sides.
5x = 2y + 6
-6 -6
6-6=0 so they would cross out. and you can't subtract 5x from 6 because they aren't like terms. Your new equation would look like 5x-6 = 2y.
Now you need to get the y alone. To do that you need to divide everything by 2 so that the 2y crosses out. 5x-6 = 2y

g questions: if a set of grades for a class has a large range and a small standard deviation, what can you say about the class? include an interpretation that is specific to grades in a class.
If a set of grades have a large range and a small standard deviation, it means that there are few students with high marks and few with low marks. Most students falls in the average region.
Range is the difference between the maximum value and the minimum value. So for the range to be higher, there must be at least one very high grade and at least a very low grade. If the maximum mark scored by the highest scorer is 95 and 10 for the lowest, the range will be 95- 10 = 85.
If one scored 99 and the lowest scorer got 5, then the range is 99-5 = 94. So higher the range means there is great difference between the highest and lowest grade.
Standard deviation means how much the value deviates from average. If it is low, that means most of the students scored near to the average.
So high range and low standard deviation means, there are few high scorers and few low scores. But most students falls in the average category.

V=10.47+38=48.476
A measurement of three-dimensional space is volume. It is frequently expressed in numerical form using SI-derived units, as well as different imperial or US-customary units. In contrast to how much space the container actually occupies, the volume of a container is typically thought of as its capacity, or the amount of fluid it could hold. Volume was initially measured using naturally occurring vessels of a comparable shape and then with standardized containers. Arithmetic formulas can be used to quickly calculate the volume of several straightforward three-dimensional shapes. If a formula for the shape's boundary is known, it is possible to use integral calculus to determine the volumes of more complex shapes. objects in the zero, one, and two dimensions have no volume.
