Laplace used this model to study the probability of the sun rising tomorrow by considering each day as a "ball" with "sunrise" or "no sunrise" as colors.
(a) Let R_i denote drawing a red ball on the ith turn. The probability that the (N+1)th ball is red given the first N balls were red is P(R_(N+1)|R_1, R_2, ..., R_N). By Bayes' theorem:
P(R_(N+1)|R_1, ..., R_N) = P(R_1, ..., R_N|R_(N+1)) * P(R_(N+1)) / P(R_1, ..., R_N)
Since drawing balls is with replacement, the probability of drawing a red ball on any turn from the ith urn is (i-1)/(N+1). Thus, P(R_(N+1)|R_1, ..., R_N) = ((i-1)/(N+1))^N * (i-1)/(N+1) / ((i-1)/(N+1))^N = (i-1)/(N+1)
(b) The probability that the first ball is red is the sum of the probabilities of drawing a red ball from each urn, weighted by the probability of selecting each urn: P(R_1) = (1/(N+1)) * Σ[((i-1)/(N+1)) * (1/(N+1))] for i = 1 to N+1
Similarly, the probability that the second ball is red:
P(R_2) = (1/(N+1)) * Σ[((i-1)/(N+1))^2 * (1/(N+1))] for i = 1 to N+1

For which mapped relation is the domain ?
Answer:
C.
Step-by-step explanation:
For any of the given functions, all of the first input values (x-values) in the relation are considered the domain values. On the other hand, the output values (y-values) are called the range values of the given equation.
The mapped relation is the domain (1, 2, 3). Since this is domain values (x-values), the correct answer will be the mapped with 1, 2, and 3 on the left side.

The value of X is 100 degree.
According to the statement
we have to find the value of x degree which represent the angle.
In this figure
we see that there are two angles which are vertically opposite angles and there is rule that the values of vertically opposite angles are always same.
So, due this reason Here the value of x is 100 degree
because in this figure the given angle which is 100 degree are vertical to the angle which we have to find and that angle which x, so, the value of x is same as the value of vertical angle.
so these angles are vertical angles. that's why x is 100 degree.

How to verify if a triangle form Pythagorean triple?Pythagoras's principle follows the rule:
c² = a² + b²
where
a and b are the legsc is the hypotenuse side.Therefore, Pythagorean triples are a² + b² = c² where a, b and c are the three positive integers. The most known and smallest triplets are (3,4,5).
If we reduced the length of the side of the triangle with the greatest common factor, it should give us 3, 4, 5.
Hence,
21, 28 and 35 has greatest common factor as 7

The average expenditure per student (based on average daily attendance) for a certain school year was $10,337 with a population standard deviation of $1560. A survey for the next school year of 150 randomly selected students resulted in a sample mean of $10, 798. Find the P-value
The true mean expenditure per student is different from $10,337.
What is hypothesis in math?
A hypothesis is a proposition that is consistent with known data, but has been neither verified nor shown to be false.There are basically two types, namely, null hypothesis and alternative hypothesis.Sample size is greater than 30 and the population standard deviation is given. Thus, in order to test
H0: µ =$10,337
H1: µ≠$10,337
The appropriate test is one sample z test.
The formula for one sample z test:
Z= x−μ / σ √ n
x−μ
x=10798
μ=10337
σ=1560
n=150
[tex]Z = \frac{10798 - 10337}{1560 / \sqrt{150} } = 3.62[/tex]
Computation of p-value:
The EXCEL formula to find the p-value for a two-tailed z-test is
“=2*(1-NORM.S.DIST(3.62, TRUE))”
Thus, the p-value obtained is 0.00029
Conclusion using α = 0.05:
Rejection rule using p-value:
If p-value ≤ α, then reject the null hypothesis.
Since, 0.00029 < 0.05, there is sufficient evidence to reject the null hypothesis.
Therefore, the true mean expenditure per student is different from $10,337.

Write the equation of the line that is parallel to the line y = -7/4x - 2 through the point (4,-2).
Answer:
y = - [tex]\frac{7}{4}[/tex] x + 5
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 )
y = - [tex]\frac{7}{4}[/tex] x - 2 ← is in slope- intercept form
with slope m = - [tex]\frac{7}{4}[/tex]
• Parallel lines have equal slopes , then
y = - [tex]\frac{7}{4}[/tex] x + c ← is the partial equation
to find c substitute (4, - 2 ) into the partial equation
- 2 = - 7 + c ⇒ c = - 2 + 7 = 5
y = - [tex]\frac{7}{4}[/tex] x + 5 ← equation of line

so, the only rules are that the sum of any pair of sides must be longer than the 3rd side (otherwise, if the 3rd side is longer, the sides could not connect).
A. 10.
so, we have

6 + 10 > 9 true
9 + 10 > 6 true
therefore this is a possible 3rd side.
B. 2.
so, we have

6 + 2 > 9 false
9 + 2 > 6 true
therefore this is NOT a possible 3rd side.

so, we have

6 + 4 > 9 true
9 + 4 > 6 true
therefore this is a possible 3rd side.
D. 15.
so, we have
6 + 9 > 15 false
6 + 15 > 9 true
9 + 15 > 6 true
therefore this is NOT a possible 3rd side (this triangle is a special case as 6+9 = 15 : it can only exist as a completely flat line and is therefore not a triangle).
E. 12.
so, we have
6 + 9 > 12 true
6 + 12 > 9 true
9 + 12 > 6 true
therefore this is a possible 3rd side.

Prove or disprove the following. In any group of two or more people, there are always at least two people who have the same number of friends. Assume that if a person p is a friend of a person q then q is also a friend of p.
Yes we can prove that in the group of more than two people that there are at least two people that have the same number friends given the condition here.
How to go about this proofLet us create a variable P. P is an individual called Joe. Now Joes seems to know all at this party. This tells us that all at this party should at least know him.
We have the set {1,2,...n-1} , given that the minimum number of persons that one person knows is 1.
Let us assume we have Harry. Harry is a party crasher who came to the party. Hence it is possible that someone like Joe that knows all at the party may not even know him. Hence the maximum persons that a person would know is given to be n. The set would then be {0, 1,...,n-2}.
There are n elements in the 2 sets that we have above. Given that n people are at this function, and there are n possibilities for the number that one person can know of the participants, then we can say that at least two people can then know equal number of persons at the party.

To calculate the time we have to use multiplication which means product of two numbers.
In 2 years agency elected 20 members. It shows like under:

We require 100 members at one end so we will multiply by 5 both sides.
10 years=100 members
