Fill in the P(X=x) values in the table below give a legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6.
The legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6 is: P(X=0) = 0.2, P(X=3) = 0.2, P(X=4) = 0.3, P(X=5) = 0.2, and P(X=6) = 0.1.
For a probability distribution to be legitimate, the probabilities of all the possible values of a random variable need to add up to 1. So, in this case, the sum of all the probabilities must be equal to 1.
For the given values, we can assign the probability of 0.2 to the values 0 and 3, 0.3 to the value 4 and 0.1 to the value 6, so that the sum of all the probabilities is 1.
Therefore, the legitimate probability distribution for the given discrete random variable X is as follows:
| Value (x) | P(X=x) |
|---|---|
| 0 | 0.2 |
| 3 | 0.2 |
| 4 | 0.3 |
| 5 | 0.2 |
| 6 | 0.1 |
The legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6 is: P(X=0) = 0.2, P(X=3) = 0.2, P(X=4) = 0.3, P(X=5) = 0.2, and P(X=6) = 0.1.

Prove divisibility

The prove that the given expression is divisible by 43 is explained below.
Divisibility of numbers.A number is said to be divisible by a given number when it leaves no remainder after the division. Example; show that 7^7 is divisible by 49.
7^7 = 823543
So that;
823543/ 49 = 16807
To prove that the expression is divisible by 43, we have;
7^8 = 5764801
7^7 = 823543
7^6 = 117649
Then,
7^8 - 7^7 + 7^6 = 5764801 - 823543 + 117649
= 4941258 + 117649
= 5058907
Then,
5058907/ 43 = 117649

What is the Probability.
The value of the conditional Probability is P(A|B) is 1/3.
What is probability ?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The main distinction between a probability and a conditional probability is that a probability is the likelihood of an event, such as A, occurring, whereas a conditional probability assumes that another event, such as B, has already happened in order to define the probability of an event, such as in the conditional probability of A given B.
Conditional probability is the likelihood that any event A will occur in the presence of another event B that is related to A. P(A|B) illustrates it.
By, Conditional Probability :
P (A∩B) =P (A∩B') - P(B)= 4/9 - 1/3 = 1/9
P(A|B) = P (A∩B)/ P(B)
= (1/9)/(1/3) = 1/3

One measure of the accuracy of a forecasting model is the:
a. trend component
b. mean absolute deviation
c. seasonal index
d. smoothing constant
Mean Absolute Deviation (MAD) is a measure of accuracy for a forecasting model.
It measures the average distance between the actual value and the predicted value, and can be calculated using the following formula: MAD = 1/n * Σ |Ai-F i |, where n is the number of data points, Ai is the actual value, and Fi is the forecasted value. MAD is often used to compare the accuracy of different forecasting models. A lower MAD value indicates that the model has a better accuracy in predicting future values. Additionally, MAD can also be used to measure the accuracy of a single forecasting model over time. If MAD increases, then the accuracy of the forecasting model is decreasing.

Taking w as the unknown number, the equation for the given statement is 2(w-8) = 5.
To solve this problem, we need to convert the given statement in mathematical form.
We assume that "w" is the unknown number in the equation.
First, we have to take a closer look at the given statement. It was stated that "twice the different of... is equal to 5". It shows that the result of equation 5 is the double value of another equation. We assume the unknown equation as y. Then:
2y = 5
Next, the rest of the statement stated that "a number and 8". From this part of statement, we know that the unknown equation "y" we assume above should be replace with "w-8". Hence:
2(w - 8) = 5
If we want to solve this question, we can solve it by dividing both sides with 2:

here, we have,
f(x)=logx
How to determine the equation of g(x)?
From the graph, the given parameters are:
f(x) = log(x)
From the graph, we can see that:
The graph of f(x) is translated left by 1 unit
The graph of f(x) is translated up by 4 units
This transformation is given as
g(x) = f(x + 1) + 4
Mathematically, this transformation can be represented as
(x, y) = (x + 1, y + 4)
When represented as a function, we have
g(x) = f(x + 1) + 4
Substitute the equation f(x) = log(x)
f(x + 1) = log(x + 1) + 4

A student decides to finance a used car over a 5-yr (60-month) period. After making a down
payment of $2000, the remaining cost of the car including tax and interest is $14,820. The
amount owed y = A(t) (in $) is given by A(t) = 14,820-247t, where t is the number of
months after purchase and 0 ≤t≤ 60. Determine the t-intercept and y-intercept and interpret
their meanings in context.
Answer:The t-intercept of a function is the point at which the function crosses the t-axis. To find the t-intercept of the function A(t) = 14,820 - 247t, we need to find the value of t when A(t) = 0. Setting A(t) = 0 and solving for t, we get:
14,820 - 247t = 0
t = (14820/247)
The t-intercept of the function is 60 months, which means that after 60 months (or 5 years) the amount owed on the car will be $0.
The y-interval of a function is the point at which the function crosses the y-axis. To find the y-intercept of the function A(t) = 14,820 - 247t, we need to find the value of A(t) when t = 0.
At t = 0, A(t) = 14,820 - 247(0) = 14,820.
The y-intercept of the function is $14,820 which means that before making the first payment, the cost of the car including tax and interest is $14,820.

let e be the amount in dollars that jacques spends on salad and pizza. if jacques buys s bowls of salad and p slices of pizza, then the total amount of money he spends (e) can be represented by the equation
The total amount of money (e) spent can be represented by the equation E = ($3.00S) + ($5.00P).
The total amount of money spent will be the sum of money sent of salad and pizza.
The total amount of salad = number of bowls of salad × cost of each bowl of salad
Similarly, the total amount of pizza = number of slices of pizza × cost of each slice of pizza
So, the combined equation will be -
Total money spent = number of bowls of salad × cost of each bowl of salad + number of slices of pizza × cost of each slice of pizza
Keep the values in above mentioned equation -
E = (S × 5) + (P × 3)
Performing multiplication of constant and variable on Right Hand Side of the equation
E = 5S + 3P
Thus, third option is correct.

What is the distance between (4,-2), (0,4)
Answer:
the distance between (4,-2) and (0,4) is √(52) or approximately 7.2 units.
Step-by-step explanation:
To find the distance between two points in a Cartesian coordinate plane, we can use the distance formula:
distance = √((x2-x1)² + (y2-y1)²)
In this case, the two points are (4,-2) and (0,4). So,
x1 = 4, y1 = -2 and x2 = 0, y2 = 4
By substituting these values in the distance formula, we get:
distance = √((0-4)² + (4-(-2))²)
distance = √((-4)² + 6²)
distance = √(16 + 36)
distance = √(52)
So the distance between (4,-2) and (0,4) is √(52) or approximately 7.2 units.
