What is probability?Probability is simply the likelihood of something occurring. When we are uncertain about the result of an event, we might discuss the probabilities of several outcomes—how likely they are. Statistics is the study of occurrences guided by probability. Probability is synonymous with possibility. It is a mathematical discipline that deals with the occurrence of a random event. The value ranges from zero to one. Probability has been introduced in mathematics to predict the likelihood of occurrences occurring. The probability is a measure of the possibility that an event will occur. It assesses the event's certainty. P(E) = Number of Favourable Outcomes/Number of Total Outcomes is the probability formula.

a multiple regression model has the form . as x1 increases by 1 unit (holding x2 constant), is expected to increase by how many units?
Y is expected to increase by 2 units.
What is Multiple Regression ?A single dependent variable and several independent variables can be analyzed using the statistical technique known as multiple regression. In order to forecast the value of the single dependent value, multiple regression analysis uses independent variables whose values are known.
In a multiple regression, the impact of numerous explanatory variables on a particular outcome is taken into account. When all other factors in the model are kept constant, it assesses the relative impact of these independent or explanatory variables on the dependent variable.
Multiple regression model =>
\(Y = 7 + 2x_1 + 9x_2\)
So, here coefficient of \(x_1\) is 2 this means that as x 1 increases by 1 unit holding x 2 constant , y is expected to increase by 2 units.

Answer:
Table 2.
Step-by-step explanation:
Recall that by definition, a linear function increases linearly. That is, the rate of change between any two points is constant.
We can go through each table and verify its rate of change.
Table 1)
For Table 1, note that y = -19 when x = 0.
When x = 1, y = -11. In other words, we added 8 for every increase of one for x.
When x = 2, y = -3. We still increased by 8 for every increase of one for x.
When x = 3, y = 5. Since -3 + 8 = 5, all points in Table 1 shows a constant rate of change.
In conclusion, Table 1 represents a linear function.
Table 2)
For Table 2, note that y = -1.5 when x = 0.
When x = 1, y = -1.5. In other words, we increased by 3 for every increase of one for x.
However, when x = 2, y = 3. This time, we only increased by 1.5 for every increase of one for x. Since the two rates are not equivalent, Table 2 is nonlinear.
Table 3)
Again, note that for Table 3, y = 15 when x = 0.
When x = 1, y = 12. So, we decreased by 3 for every increase of one for x.
When x = 2, y = 9. And when x = 3, y = 6. For both cases, we still decreased by 3 for every increase of one for x.
In conclusion, Table 3 represents a linear function.
Therefore, the table that represents a nonlinear function is Table 2.

What is the solution of the system of equations below?
x + 3y = 7
2x - y = 7
Answer:
y = 1
x = 4
Step-by-step explanation:
x + 3y = 7 → ( 1 )
2x - y = 7 → ( 2 )
First, let us make x the subject in equation ( 1 ).
x = 7 - 3y → ( 3 )
Let us find the value of y.
For that let us take equation (1) & replace x with ( 7 - 3y ).
2x - y = 7
2 ( 7 - 3y ) - y = 7
Solve the brackets.
14 - 6y - y = 7
Combine like terms.
14 - 7y = 7
Subtract 14 from both sides.
-7y = 7 - 14
-7y = -7
Divide both sides by -7.
y = 1
Let us find value of x
For that let us take equation (3) & replace y with 1.
x = 7 - 3y
x = 7 - 3 × 1
x = 7 - 3
x = 4

The UCR (Uniform Crime Reporting) is B. not a truly reliable measure.
The UCR is a program established by the FBI in 1930 to collect and analyze crime statistics from law enforcement agencies across the United States. Although it provides useful data and insights into crime trends, it is not without its limitations. One significant issue with the UCR is that it relies on voluntary reporting from law enforcement agencies, meaning that some areas may not provide complete or accurate data. This can lead to an underrepresentation of certain crimes or inconsistencies in reporting across jurisdictions.
Another limitation is that the UCR only includes reported crimes, excluding any unreported criminal activity. This means that the data does not necessarily provide a comprehensive picture of all crimes occurring in a given area. Additionally, the UCR uses a hierarchy rule, meaning that if multiple crimes are committed during a single incident, only the most severe crime is counted. This can result in an undercounting of less severe but still significant crimes.
In summary, although the UCR provides valuable information on crime trends and patterns, it is not a truly reliable measure due to its reliance on voluntary reporting, exclusion of unreported crimes, and hierarchy rule. Therefore, the correct option is B.

Step-by-step explanation:
of undetermined coefficients to solve (a) y' – 4y = 16xe -2x + 8x + 4 8r +4 . (b) . Y' – Y = (2x + xe2+ 22,21 & y'y = + +
To solve the given differential equations using the method of undetermined coefficients, we need to find a particular solution that satisfies the non-homogeneous equation. So, the general solution is given by: (a) y = y_h + y_p = Ce^(4x) + (-x - 4xe^(-2x) + 8x^2 - 1)e^(-2x) + 8x - 1, (b) y = y_h + y_p = Ce^x + (-x + 22.21e^x)
Let's solve each equation separately:
(a) y' - 4y = 16xe^(-2x) + 8x + 4
Step 1: Solve the associated homogeneous equation:
The homogeneous equation is y' - 4y = 0, which has the solution y_h = Ce^(4x), where C is a constant.
Step 2: Track down a specific non-homogeneous equation solution:
Since the non-homogeneous term contains terms like xe^(-2x) and x, we assume a particular solution of the form:
y_p = (A + Bx)e^(-2x) + Cx + D
Differentiating y_p, we have:
y'_p = (-2A + B - 2Bx)e^(-2x) + C
Substituting y_p and y'_p into the original equation, we get:
(-2A + B - 2Bx)e^(-2x) + C - 4((A + Bx)e^(-2x) + Cx + D) = 16xe^(-2x) + 8x + 4
Matching coefficients of like terms on both sides, we get:
-2A + B - 4A - 4D = 0 (coefficients of e^(-2x))
-2B - 4C = 16x (coefficients of xe^(-2x))
-2A + C = 8x (coefficients of x)
-4D = 4 (constant term)\
Solving these equations, we find A = -1, B = -4, C = 8, and D = -1.
Therefore, the particular solution is:
y_p = (-x - 4xe^(-2x) + 8x^2 - 1)e^(-2x) + 8x - 1
The general solution is given by:
y = y_h + y_p = Ce^(4x) + (-x - 4xe^(-2x) + 8x^2 - 1)e^(-2x) + 8x - 1
(b) y' - y = (2x + xe^2) + 22,21
Step 1: Solve the associated homogeneous equation:
The homogeneous equation is y' - y = 0, which has the solution y_h = Ce^x, where C is a constant.
Step 2: Track down a specific non-homogeneous equation solution:
Since the non-homogeneous term contains terms like 2x, xe^2, and 22.21, we assume a particular solution of the form:
y_p = Ax + B + Cx^2 + De^x
Differentiating y_p, we have:
y'_p = A + C + 2Cx + De^x
Substituting y_p and y'_p into the original equation, we get:
(A + C + 2Cx + De^x) - (Ax + B + Cx^2 + De^x) = (2x + xe^2) + 22.21
Matching coefficients of like terms on both sides, we get:
A - Ax = 2x + xe^2 (coefficients of x)
C - Cx^2 = 0 (coefficients of x^2)
C + D = 22.21 (constant term)
According to the first equation, A = -1.
From the second equation, we have C = 0.
Substituting A = -1 and C = 0 into the third equation, we get D = 22.21.
Therefore, the particular solution is:
y_p = -x + 22.21e^x
The general solution is given by:
y = y_h + y_p = Ce^x + (-x + 22.21e^x)

At another table, the customers ordered 5 child meals and 3 adult meals, which cost $125 in total. How much does each child meal and adult meal cost?
Answer:
Read below for full answer :)
Step-by-step explanation:
We can conclude that the total cost of all meals was $205.
There were a total of 8 kids meals and 5 adult meals.
You'd have to divide 205 by 8, and you'd get 25.625.
Then, divide 205 by 5, and you'd get 41.
For example, we could say that each childrens meal was $15 ($120 total in kid's meals), and each adult was $17 ($85 total in adult meals).
When you total $85 and $120, it then given you a sum of $205.
There are many ways to complete this equation, but i feel that this is the easiest way.

Bradley is planning to publish a cookbook. He consults with the author, and they decide to include 150 recipes, with one on each page. They also decide to divide the book into three sections: vegetarian dishes, meat dishes, and desserts.
Find statistics to determine the ratio of vegetarians to non-vegetarians in your country. Use this to determine what the ratios of vegetarian and meat recipes to all recipes should be in Bradley’s cookbook.
The vegetarian ratio would presumably be: 5 million / (5 million + 50 million) = 0.100 which is equivalent to 10%.
To calculate the proportion of vegetarians to non-vegetarians in Bradley's country, one needs to first assess the amount of vegetarians and non-vegetarians living there.
This can be accomplished through reliance on surveys, census data, or further research methods. By dividing the number of vegetarians in comparison to the total number of both vegetarians and non-vegetarians, one can generate a ratio that reveals this information.
For example, let's say Bradley's country contains 5 million vegetarians among a general population of 50 million people. The vegetarian ratio would presumably be: 5 million / (5 million + 50 million) = 0.100 which is equivalent to 10%.
Similarly, as Bradley attempts to distinguish appropriate vegetable, meat, and dessert recipes for his cookbook - 10%, 18%, and 42% respectively - he can utilize this same formula. As an example it could be assumed that if there are 150 recipes in total then 15 would incorporate vegetables as part of their contents - 10% out of 150 recipes - while 30% or 27 recipes would idealized around containing meat components as well as 70% or 63 desserts.
