The equation 1 - 0.99c - 1.1 = 0 can be rearranged as 0.99c + 1.1 = 1. This equation shows that the function g(x) = √(0.99x + 1.1) satisfies the conditions of the main statement on convergence of the Fixed-Point Iteration (FPI) method on the interval [1, 2]. To verify this, we can plot the graphs of y = √(0.99x + 1.1), y = 1, and y = 2 for x in the range [1, 2] on the Wolfram Alpha website.
Upon plotting the graphs, we can observe that the graph of y = √(0.99x + 1.1) intersects with y = 1 and y = 2 in the interval [1, 2]. This intersection indicates that the function g(x) has a fixed point within this interval. Therefore, the Fixed-Point Iteration method is expected to converge for this problem.
To find an approximation of the fixed point p of g(2) using the Fixed-Point Iteration method, we can start with an initial approximation p₀ = 1. We can iteratively calculate the values of pₙ for n = 1, 2, 3, ... until the relative error RE(pₙpₙ₋₁) is less than 10⁻⁷.
Using the formula pₙ = √(0.99pₙ₋₁ + 1.1), we can perform the calculations as shown in the following table:
| pₙ₋₁ | pₙ | RE(pₙpₙ₋₁) | n || 1 | 1.045700140... | - | 0 || 1.045700140... | 1.046371249... | 0.0640145... | 1 || 1.046371249... | 1.046371478... | 1.64916... × 10⁻⁵ | 2 |After several iterations, we can see that the relative error becomes smaller than 10⁻⁷. Therefore, the approximation pₙ is a satisfactory solution for the fixed point of g(2), which corresponds to the root of the polynomial f(x) = 24 - 0.99x² - 1.1 in the interval [1, 2].
In conclusion, the Fixed-Point Iteration method converges for the given problem, and the approximation pₙ provides a suitable estimate for the root of the polynomial within the specified tolerance.

Step-by-step explanation:
4 cards are drawn from a deck of shuffled cards without
replacement.
Find the probability that:
a) All are kings
b) All are red cards
a) The probability of drawing all kings from a shuffled deck of cards without replacement is approximately 0.0000014, or 1.4 in 1 million.
b) The probability of drawing all red cards from a shuffled deck without replacement is approximately 0.000000103, or 1.03 in 10 million.
a) Probability of drawing all kings:
To calculate the probability of drawing all kings, we need to determine the total number of possible outcomes and the number of favorable outcomes. Let's break it down step by step:
Step 1: Total number of possible outcomes
In a standard deck of 52 playing cards, there are four kings. When we draw one card, there are 52 cards to choose from. For the second draw, only 51 cards remain, and so on. Therefore, the total number of possible outcomes for drawing four cards without replacement is:
52 × 51 × 50 × 49 = 649,740
Step 2: Number of favorable outcomes
Since we want all four cards to be kings, there are only four kings in the deck. When we draw the first card, there is a 4/52 chance of it being a king. For the second card, the probability reduces to 3/51 since there are three kings remaining out of 51 cards. Similarly, for the third and fourth cards, the probabilities become 2/50 and 1/49, respectively. Therefore, the number of favorable outcomes is:
(4/52) × (3/51) × (2/50) × (1/49) = 1/270,725
Step 3: Calculating the probability
Finally, we can calculate the probability of drawing all kings by dividing the number of favorable outcomes by the total number of possible outcomes:
P(all kings) = (1/270,725) / (649,740) ≈ 0.0000014
b) Probability of drawing all red cards:
Similarly, let's calculate the probability of drawing all red cards from the deck. We follow the same steps:
Step 1: Total number of possible outcomes
When we draw the first card, there are 26 red cards in a deck of 52. For the second draw, there are 25 red cards remaining out of 51, and so on. Hence, the total number of possible outcomes for drawing four cards without replacement is:
26 × 25 × 24 × 23 = 358,800
Step 2: Number of favorable outcomes
Since we want all four cards to be red, there are 26 red cards in the deck. The probability of drawing a red card for the first draw is 26/52. For the second draw, the probability becomes 25/51, for the third draw it is 24/50, and for the fourth draw, it is 23/49. Thus, the number of favorable outcomes is:
(26/52) × (25/51) × (24/50) × (23/49) ≈ 0.037
Step 3: Calculating the probability
The probability of drawing all red cards is the ratio of the number of favorable outcomes to the total number of possible outcomes:
P(all red cards) = (0.037) / (358,800) ≈ 0.000000103

Problem 6. Miss Ang buys a dozen of eggs (12 eggs in an egg tray) from HS Farm every day, starting at Day 1. For each egg produced by HS Farm, there is a 0.001 chance that it is spoiled.
(a) Find the probability of that in one week, Miss Ang bought at most (≤) 2 trays of eggs with each having at least one spoiled egg. Write your answer (applying to (b) and (c) as well) up to 3 decimal point.
(b) Let N be the first day (counted from Day 1) that Miss Ang bought a tray of eggs containing at least one spoiled. Find the expected value of N.
(c) Suppose Day 1 is Sunday. Compute the probability that Day N is also Sunday.
a) The probability that in one week, Miss Ang bought at most (≤) 2 trays of eggs with each having at least one spoiled egg=0.016
b) The expected value of N=86.6
c) The probability that Day N is also Sunday=1/7.
Explanation:
a)
For 1 day, 1 tray must contain no spoiled eggs: 0.999^12,
1 tray must have at least 1 spoiled egg: 1 - 0.999^12,
and the probability that Miss Ang has 2 trays, each containing at least 1 spoiled egg in one day:
(1 - 0.999^12) * (1 - (0.999^12 + 11 * 0.001 * 0.999^11)) = 0.00245
For 7 days, the probability that Miss Ang has at most 2 trays, each containing at least 1 spoiled egg:
= 0.00245 * C(7,0) * 1^0 * (1 - 1)^7 + 0.00245 * C(7,1) * 1^1 * (1 - 1)^6 + 0.00245 * C(7,2) * 1^2 * (1 - 1)^5
= 0.01622 ≈ 0.016
b)
Let X be the number of trays that Miss Ang has to buy to get the first tray containing at least 1 spoiled egg. Then X follows a geometric distribution with parameter
p = 1 - 0.999^12 and
E(X) = 1/p = 1/0.011543 ≈ 86.6 (rounded to the nearest 0.1).
c)
Since Miss Ang buys one tray of eggs a day, the probability that Day N is Sunday is 1/7. Therefore, the probability that Day N is Sunday given that it is the first day that Miss Ang bought a tray of eggs containing at least one spoiled is also 1/7.

a) The probability of that in one week, Miss Ang bought at most (≤) 2 trays of eggs with each having at least one spoiled egg:
P(X ≤ 2) = 0.2966763801
b) The expected value of N = 83.8059327318 days
c) The probability that Day N is also Sunday= 0.1406909760
(a)
For each egg produced by HS Farm, there is a 0.001 chance that it is spoiled. Therefore, the probability that an egg is not spoiled is
1-0.001 = 0.999.
Since Miss Ang buys one dozen eggs every day, the probability that all 12 eggs in a tray are not spoiled is
(0.999)¹² = 0.98806738389.
Therefore, the probability that there is at least one spoiled egg in a tray is
1 - 0.98806738389 = 0.01193261611.
The probability that Miss Ang buys at most 2 trays of eggs with each having at least one spoiled egg in one week (7 days) can be found using the Poisson distribution with a mean of λ = 1.19574793916.
Therefore,
P(X ≤ 2) = 0.2966763801
(b)
Let N be the first day that Miss Ang bought a tray of eggs containing at least one spoiled.
Since Miss Ang buys one tray of eggs every day, the probability that N = n is the probability that the tray she buys on day n has at least one spoiled egg, and all the trays she buys on days 1, 2, ..., n - 1 have no spoiled eggs.
This probability is given by
[tex]P(N = n) = (0.98806738389)ⁿ⁻¹(0.01193261611)[/tex]
The expected value of N can then be found by taking the sum of nP(N = n) over all possible values of n.
This gives
[tex]E(N) = Σn=1∞nP(N = n)[/tex]
[tex]= Σn=1∞(0.98806738389)ⁿ⁻¹(0.01193261611)[/tex]
n= 83.8059327318 days.
(c)
Suppose Day 1 is Sunday. Since Miss Ang buys one tray of eggs every day, Day N is also Sunday if and only if N ≡ 1 (mod 7).
Using the same method as in part (b), we get
[tex]P(N ≡ 1 (mod 7)) = Σk=0∞P(N = 7k + 1)[/tex]
=[tex]Σk=0∞(0.98806738389)ⁿ⁻¹(0.01193261611)[/tex]

Reading Improvement Program To help students improve their reading, a school district decides to implement a reading program. It is to be administered to the bottom 14% of the students in the district, based on the scores on a reading achievement exam. If the average score for the students in the district is 124.5, find the cutoff score that will make a student eligible for the program. The standard deviation is 15. Assume the variable is normally distributed. Round 2-value calculations to 2 decimal places and the final answer to the nearest whole number.
Rounding the cutoff score to the nearest whole number, the cutoff score that will make a student eligible for the reading program is approximately 108.
To find the cutoff score that will make a student eligible for the reading program, we need to determine the score below which the bottom 14% of students fall.
Since the variable is normally distributed and we know the average score and standard deviation, we can use the Z-score formula to find the cutoff score.
The Z-score formula is:
[tex]\[Z = \frac{X - \mu}{\sigma}\][/tex]
Where:
Z is the Z-score,
X is the raw score,
[tex]\mu[/tex] (mu) is the mean, and
[tex]\sigma[/tex] (Sigma) is the standard deviation.
We want to find the Z-score that corresponds to the bottom 14% of students, which means the area to the left of the Z-score is 0.14.
Using a standard normal distribution table or calculator, we can find the Z-score that corresponds to an area of 0.14, which is approximately -1.08.
Now we can rearrange the Z-score formula to solve for X, the cutoff score:
[tex]\[X = Z \cdot \sigma + \mu\][/tex]
Substituting the values we have:
[tex]\[X = -1.08 \cdot 15 + 124.5\][/tex]
Calculating the expression:
[tex]\[X = -16.2 + 124.5\]\\X = 108.3[/tex]
Rounding the cutoff score to the nearest whole number, the cutoff score that will make a student eligible for the reading program is approximately 108.

2. Write the equation of a circle that has a diameter of 12 units if its center is at (4,7).
O (x – 4)2 + (y – 7)2 = 144
O (x +4)2 + (y + 7)2 = 144
O (x – 4)2 + (y-7)2 = 36
O (x+4)2 + (y + 7)2 = 36
Answer:
The Answer is B
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here diameter = 12, thus radius = 12 ÷ 2 = 6 and (h, k) = (2.5, - 3.5), thus
(x - 2.5)² + (y - (- 3.5))² = 6², that is
(x - 2.5)² + (y + 3.5)² = 36 ← equation of circle

Approximate the stationary matrix S for the transition matrix P by computing powers of the transition matrix P. P= [ 0.37 0.63] [ 0.19 0.81] S= (Type an integer or decimal for each matrix element Round to four decimal places as needed.)
To approximate the stationary matrix S for the transition matrix P, we need to compute powers of the transition matrix P until it reaches a stable matrix.
Starting with P = [0.37 0.63; 0.19 0.81], we can compute powers of P as follows:
P^2 = P * P
= [0.37 0.63; 0.19 0.81] * [0.37 0.63; 0.19 0.81]
= [0.2746 0.7254; 0.1538 0.8462]
P^3 = P * P^2
= [0.37 0.63; 0.19 0.81] * [0.2746 0.7254; 0.1538 0.8462]
= [0.2421 0.7579; 0.1873 0.8127]
P^4 = P * P^3
= [0.37 0.63; 0.19 0.81] * [0.2421 0.7579; 0.1873 0.8127]
= [0.2222 0.7778; 0.1941 0.8059]
Continuing this process, we find:
P^5 = [0.2149 0.7851; 0.1957 0.8043]
P^6 = [0.2124 0.7876; 0.1961 0.8039]
P^7 = [0.2117 0.7883; 0.1961 0.8039]
As we can see, the matrix P^7 is very close to the stationary matrix S. Therefore, we can approximate the stationary matrix S as:

The solution to the system of equations by substitution is x = 3 and y = -8.
To solve the system of equations by substitution:
Solve one equation for one variable in terms of the other variable. Let's solve the first equation for x:
4x - y = 20
4x = y + 20
x = (y + 20)/4
Substitute this expression for x into the second equation:
-2x - 2y = 10
-2((y + 20)/4) - 2y = 10
(y + 20)/2 - 2y = 10
(y + 20) - 4y = 20
-y - 20 - 4y = 20
-5y = 40
y = -8
Substitute the value of y back into the first equation to find x:
4x - (-8) = 20
4x + 8 = 20
4x = 20 - 8

Step-by-step explanation:
we are given two conditions
Matt bought 7 shirts for a total of $38Tee shirts cost 5 dollars and long sleeve shirts cost 6 dollarswe want to figure out how many each type of shirt he bought
let tee and sleeve shirts be t and s respectively
according to the first condition
[tex] \displaystyle t + s = 7[/tex]
according to the second condition
[tex] \displaystyle5t + 6s = 38[/tex]
therefore
our system of linear equation is
[tex] \displaystyle\begin{cases}t + s = 7 \\ 5t + 6s = 38 \end{cases}[/tex]
so
now we need our algebra skills to figure out t and s
to do so we can use substitution method
cancel s from both sides of the first equation:
[tex] \displaystyle t = 7 - s \: \cdots \: i[/tex]
now substitute the value of i equation to the second equation:
[tex] \displaystyle 5(7 - s) + 6s = 38[/tex]
distribute:
[tex] \displaystyle 35 - 5s+ 6s = 38[/tex]
collect like terms:
[tex] \displaystyle s + 35 = 38[/tex]
cancel 35 to both sides:
[tex] \displaystyle \therefore s = 3[/tex]
now substitute the value of s to the i equation:
[tex] \displaystyle t = 7 - 3 \\ \therefore \: t = 4[/tex]

To find the slope when given a table, just pick two points, subtract the y values, and then divide them by the x values after you subtract them as well. Here's what I mean...
Let's use 1, -11 and 5, -35
So...
-35 - (-11)
This is the change in y. -35 - (-11) is the same thing as -35 + 11 (subtracting negative switches to adding it)
You get -24
Now, the change in x.
5 - 1 = 4
So, -24/4 and you get the slope of : -6

Two events A and B are said to be mutually exclusive if they cannot occur at the same time, meaning that the intersection of A and B is an empty set. In probability terms, if A and B are mutually exclusive, then P(A and B) = 0.
Given that P(A) = 0.4 and P(A or B) = 0.7, we can use the formula for the probability of the union of two events: P(A or B) = P(A) + P(B) - P(A and B). Since we want to find the values of x for which A and B are mutually exclusive, we set P(A and B) = 0:
0.7 = 0.4 + x - 0
0.7 = 0.4 + x
x = 0.3
Therefore, for A and B to be mutually exclusive, the value of x must be 0. For any other value of x, A and B will have a non-empty intersection and therefore will not be mutually exclusive.
On the other hand, two events A and B are considered independent if the occurrence of one event does not affect the probability of the other event. In probability terms, if A and B are independent, then P(A and B) = P(A) * P(B).
Since P(A) = 0.4 and P(B) = x, we can set up the equation:
P(A) * P(B) = 0.4 * x
For A and B to be independent, this equation must hold for any value of x. Therefore, A and B are independent for any value of x between 0 and 0.3, inclusive.
