Determine the missing digit (denoted with*) for the American Express Traveler's Check identification number 783920*814 a) 3
b) 2
c) 6
d) 9
The missing digit for the American Express Traveler's Check identification number is option (C) 6 is the correct answer.
In this question,
A Check Digit is a decimal (or alphanumeric) digit added to a number for the purpose of detecting the sorts of errors humans typically make on data entry.
A check digit is a digit added to a string of numbers for error detection purposes. Normally, the check digit is computed from the other digits in the string. A check digit helps digital systems detect changes when data is transferred from transmitter to receiver.
The last digit of a bar code number is a calculated check digit. The check digit is calculated from all the other numbers in the bar code and helps to confirm the integrity of your bar code number.
The American Express Traveler's Check identification number is 783920*814.
In Airline tickets, there are several digits plus a check digit.
Divide the ID number by 7. The check digit is the remainder.
Sum of digits = 7+8+3+9+2+0+8+1+4
⇒ 42
Now divide the sum by 7, the remainder is
⇒ 42 mod 7 = 42 - (5×7)
⇒ 42 mod 7 = 6
Hence we can conclude that the missing digit for the American Express Traveler's Check identification number is option (C) 6 is the correct answer.

I need to find the equation of the line
Answer:
y = 3x + 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 3) ← 2 points on the line

Which rule states that when two outcomes are independent, the probability that these outcomes occur together is the product of their individual probabilities
The rule which states that when two outcomes are independent, the probability that these outcomes occur together is the product of their individual probabilities is "Multiplicative rule".
What is Multiplicative rule?The likelihood of both events A and B occurring, in accordance with the probability multiplication rule, is equal to the product of the probability of B occurring and the conditional probability of event A occurring given that event B occurs.
If A and B are dependent events, then the probability of both events occurring simultaneously is given by:
[tex]P(A \cap B)=P(B) \cdot P(A \mid B)[/tex]
The likelihood of both events occurring simultaneously in an experiment where A and B are two independent events is given by:
[tex]P(A \cap B)=P(A) \cdot P(B)[/tex]
Multiplication Theorem of Probability:
The multiplication guidelines that we use in probability have already been taught to us, including;
[tex]\begin{aligned}&P(A \cap B)=P(A) \times P(B \mid A) \text {; if } P(A) \neq 0 \\&P(A \cap B)=P(B) \times P(A \mid B) \text {; if } P(B) \neq 0\end{aligned}[/tex]
Therefore, the relationship between two events is explained by the probability multiplication rule.
Set AB represents the events in which both events A and B have occurred for two events A and B related to a sample space S.
Consequently, (AB) indicates that occurrences A and B happened at the same time. You can write the event AB as AB.
Using the characteristics of conditional probability, the likelihood of event AB is calculated.

Find a and k so that the given points lie on the parabola (An algebraic solution is required)
The value of a is -3 and the value of k is 10
A parabola is a U-shaped plane curve where any point is equidistant from a fixed point (known as the focus) and from a fixed line known as the directrix. The parabola is an integral part of the conic section topic
The section of a right circular cone by a plane parallel to the generator of the cone is a parabola. It is the location of a point that moves so that the distance from the fixed point (the focus) is equal to the distance from the fixed line (the directrix).
The fixed point is called the focus
A fixed line is called a directrix
Solving an algebraic equation is the process of finding a number or set of numbers that, when substituted for the variables in the equation, reduce them to an identity. Such a number is called the root of the equation
Here the equation y = a(x -2)^2 + k...........(1)
and two points A(1,7) and B(4, -2) is given
We need to find the value of a and k
Put A(1,7) in equation (1) , we get,
7 = a + k ,therefore k = 7 - a......(2)
Put B(4, -2) in equation (1), we get,
-2 = 4a + k........(3)
Put k= 7-a in (3)
-2 = 4a+7 -a
3a = -9
a= -3
From equation (2) , we get k = 7-(-3)= 10
Hence the value of k is 10 and the value of a is -3

For the given points to lie on the parabola,
a = -3 and k = 10.
An equation of a curve that has a point on it that is equally spaced from a fixed point and a fixed line is referred to as a parabola. The parabola's fixed line and fixed point are together referred to as the directrix and focus, respectively. It's also crucial to remember that the fixed point is not located on the fixed line. A parabola is a locus of any point that is equally distant from a given point (focus) and a certain line (directrix).
According to the question,
Equation of parabola : y = a[tex](x-2)^{2}[/tex] + k
Points A(1,7) and B(4,-2)
For the points to lie on the parabola,
7 = a[tex](1-2)^{2}[/tex]+k
7 = a + k
Similarly,
-2 = a[tex](4-2)^{2}[/tex] + k

According to the weather report, there is a 25% chance of snow in the mountains tomorrow. how likely is it to snow tomorrow in the mountains?
It is likely is it to snow tomorrow in the mountains is 1/4
A chance is the occurrence of events without apparent purpose or cause. It is simply the possibility that something will happen. When chance is defined in mathematics, it is called probability. Probability is the extent to which an event is likely to occur, measured by the ratio of favorable cases to the total number of possible cases. Mathematically, the probability that an event occurs is equal to the ratio of the number of cases favorable to a particular event to the number of all possible cases. The theoretical probability of an event is referred to as P(E). P(E) = number of outcomes more favorable to E/Nnumber of all possible outcomes of the experiment

Find the lengths of AB, BC, and CA
AB = [tex]\sqrt{(4-(-1))^{2} + (-1-4)^{2} }[/tex] = 5[tex]\sqrt{2}[/tex] ≈ 7.1
BC = [tex]\sqrt{(0-(-1))^{2} + (-3-4)^{2} }[/tex] = 5[tex]\sqrt{2}[/tex] ≈ 7.1
CA = [tex]\sqrt{(0-4)^{2} + (-3-(-1))^{2} }[/tex] = 2[tex]\sqrt{5}[/tex] ≈ 4.5
7.1 + 7.1 + 4.5 = 18.7
Last week salazar played 13 more tennis games than perry. if they played a combined total of 53 games. How many games did salazar play?
If last week Salazar played 13 more tennis games than Perry and they played a combined total of 53 games, then Salazar played a total of 33 games.
Let the total number of games played by Perry be x.
It is given that, Salazar played 13 more tennis games than Perry.
⇒ Total games played by Salazar = x + 13
Also, Salazar and Perry played a combined of 53 games.
Hence, total number of tennis games played by Salazar and Perry = 53
⇒ Games played by Salazar + Games played by Perry = 53
⇒ x + (x + 13) = 53
2x + 13 = 53
2x = 53 - 13
2x = 40
x = 40 / 2
x = 20
Therefore, total number of games played by Salazar = x+13
= 20 + 13
= 33
Thus, Salazar played total 33 games.
