The tree diagram represents the sample space for the repeated experiment of a coin being tossed 4 times.
Determine P(at least 2 talls).
Answers
The probability of getting at least 2 tails in 4 coin tosses is 11/16 or approximately 0.6875.
What is probability?Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.
According to given information:To determine P(at least 2 tails), we need to add up the probabilities of all the outcomes in the sample space that have at least 2 tails.
Looking at the tree diagram, we can see that there are 11 outcomes that have at least 2 tails:
TTTT TTTH TTHT TTHH THTT THHT THTH HTTT HTTH HTHT HHTT
The probability of each outcome can be found by multiplying the probabilities along the branches that lead to that outcome. Since the coin is fair, the probability of getting heads or tails on any given toss is 1/2.
So for example, the probability of the outcome TTHH is (1/2) x (1/2) x (1/2) x (1/2) = 1/16.
We can find the probability of getting at least 2 tails by adding up the probabilities of the 11 outcomes listed above:
P(at least 2 tails) = [tex](1/2)^4[/tex] + 4 x [tex](1/2)^3[/tex] x (1/2) + 6 x [tex](1/2)^2[/tex] x [tex](1/2)^2[/tex]
P(at least 2 tails) = 1/16 + 4/16 + 6/16 = 11/16
Therefore, the probability of getting at least 2 tails in 4 coin tosses is 11/16 or approximately 0.6875.

At a large high school, 20% of the students prefer to have a salad for lunch. What is the average number of people you must ask before you find someone would prefer a salad for lunch?
Answers
We can expect to ask about 2-3 students before finding someone who prefers a salad for lunch, on average.
What is probability?Calculating the possibility or probability that a specific event will occur uses the concept of probability.
It is a number between 0 and 1, with 0 denoting impossibility and 1 denoting certainty of the event.
Fractions, decimals, and percentages can all be used to express probabilities.
Assuming that each student's preference for lunch is independent of the others, the probability of any given student preferring a salad is 20% or 0.2.
The probability of the first student you ask preferring a salad is 0.2. If they don't prefer a salad, you move on to the next student.
The probability of the second student preferring a salad, given that the first student didn't, is also 0.2. The probability of neither of the first two students preferring a salad is (1-0.2) × (1-0.2) = 0.64.
In general, the probability of the nth student preferring a salad, given that none of the previous n-1 students did, is also 0.2. The probability of none of the first n-1 students preferring a salad is (1-0.2)ⁿ-¹.
So the expected number of students you must ask before finding someone who prefers a salad is:
E(x) = 1×(0.2) + 2×(1-0.2)(0.2) + 3(1-0.2)²×(0.2) + ...
This is an infinite series, but we can approximate it by truncating it after a certain number of terms. Let's say we stop after 10 terms:
E(x) ≈ 1×(0.2) + 2×(1-0.2)(0.2) + 3(1-0.2)²×(0.2) + ... + 10×(1-0.2)⁹ × (0.2)
E(x) ≈ 2.48

Functions are in the world all around us. You have used functions to model phenomena and to
make predictions. Mathematically, you can add, subtract, multiply, and divide functions, and you
can also create a composition of functions.
A composition of functions occurs when you evaluate one function using another function, or
even with the same function. A composition of functions is useful when a change in one function
will create a change in another function, which, in turn, affects a third function. For example,
suppose that humans build a housing development on land that was previously used as a corn
field. This change in land usage causes the number of birds in the area to decrease, which causes
the number of mosquitos to increase. You could model the increase in the number of mosquitoes
as a function of the number of birds in the area, which is a function of the number of humans that
live on that land.
You can also use the composition of functions to show that one function is the inverse of another
function. Recall that the graphs of inverse functions are reflections of each other over the line .
Think about these ideas as you read through the scenario below.

Answers
Answer:
To find the perimeter of the rectangle, we need to add up the lengths of all four sides.
The horizontal sides of the rectangle have a length of 3 - (-1) = 4 units.
The vertical sides of the rectangle have a length of 3 - (-3) = 6 units.
Therefore, the perimeter of the rectangle is:
2(4 units) + 2(6 units) = 8 units + 12 units = 20 units.
Therefore, the perimeter of the rectangle is 20 units. Answer: 20 units.
The perimeter of the rectangle is 20 units.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:

We have,
Using the distance formula, the length of the side between (-1,3) and (3,3).
= √[(3 - (-1))² + (3 - 3)²]
= √16
= 4
Similarly, the length of the side between (3,3) and (3,-3).
= √[(3 - 3)² + (3 - (-3))²]
= √36
= 6
The length of the side between (3,-3) and (-1,-3) is also 4, and the length of the side between (-1,-3) and (-1,3) is 6.

d. 86, 54
e. 87, 55
Explain in detail how you got to the answer.
Answers
Let's use the variables w and l to represent the current ages of the wool and linen tapestries, respectively.
From the problem, we know that:
w = l + 32 (the wool tapestry is 32 years older than the linen tapestry)
w - 20 = 2(l - 20) (twenty years ago, the wool tapestry was twice as old as the linen tapestry)
We can simplify the second equation by distributing the 2:
w - 20 = 2l - 40
Now we can substitute the first equation into the second equation to eliminate w:
(l + 32) - 20 = 2l - 40
Simplifying this equation, we get:
l + 12 = 2l - 40
Adding 40 to both sides:
l + 52 = 2l
Subtracting l from both sides:
l = 52
Now we can use the first equation to find w:
w = l + 32 = 52 + 32 = 84
Therefore, the present age of the wool tapestry is 84 years old, and the present age of the linen tapestry is 52 years old.
So the answer is option (b) 84, 52.

Your friend is considering how much he should invest in his new IRA. He is debating if he should invest the full $800 he was planning to or just $400 and use the extra money to buy a couple of pairs of sneakers he had been eyeing. What advice would you give? Use math to justify your answer
Answers
Answer:
invest full 800$
Step-by-step explanation:
I would advise my friend to invest the full $800 in his new IRA. While buying a couple of pairs of sneakers may provide immediate satisfaction, investing in an IRA can have long-term financial benefits.
If we assume an average annual return of 8% for his IRA, then the $800 investment would grow to approximately $4,536 after 30 years. On the other hand, if he only invests $400 and spends the remaining $400 on sneakers, then the investment would only grow to approximately $2,268 after 30 years.
Thus, by investing the full $800, my friend would have a potential gain of over $2,268 compared to if he only invested $400. Furthermore, investing in an IRA can provide tax benefits and potentially reduce his taxable income, providing additional financial benefits.In summary, while it may be tempting to use some of the money for immediate gratification, investing the full $800 in an IRA can provide long-term financial benefits that outweigh the short-term satisfaction of purchasing a couple of pairs of sneakers.

Consider a political discussion group consisting of 10 democrats, 9 republicans, and 3 independents. Suppose that two group members are randomly selected, in succession, to attend a political convention. Find the probability of selecting no republicans
Answers
The probability of selecting no Republicans is approximately 0.2102, or about 21.02%.
What is probability?
Probability is a measure of the likelihood of an event occurring.
There are a total of 22 members in the group, consisting of 10 Democrats, 9 Republicans, and 3 Independents.
To find the probability of selecting no Republicans, we need to consider the possible ways in which two members can be selected without any Republicans being chosen.
There are two cases to consider:
The first person selected is not a Republican, and the second person selected is also not a Republican.
The first person selected is a Republican, and the second person selected is not a Republican.
Case 1: The probability of selecting a non-Republican member on the first draw is (10 + 3)/22, since there are 10 Democrats and 3 Independents out of 22 members. After the first member is selected, there are 21 members left, including 9 Republicans. The probability of selecting another non-Republican member on the second draw is (10 + 3 - 1)/(22 - 1), since there is one fewer member in the group after the first draw. Therefore, the probability of selecting no Republicans in this case is:
(10 + 3)/22 * (10 + 3 - 1)/(22 - 1) = 13/77
Case 2: The probability of selecting a Republican member on the first draw is 9/22, since there are 9 Republicans out of 22 members. After the first member is selected, there are 21 members left, including 10 Democrats and 3 Independents. The probability of selecting a non-Republican member on the second draw is (10 + 3)/(22 - 1), since there is one fewer member in the group after the first draw and we cannot select the Republican member again. Therefore, the probability of selecting no Republicans in this case is:
9/22 * (10 + 3)/(22 - 1) = 27/418
The total probability of selecting no Republicans is the sum of the probabilities in the two cases:
13/77 + 27/418 = 0.2102 (rounded to four decimal places)
Therefore, the probability of selecting no Republicans is approximately 0.2102, or about 21.02%.

=> (x³⁽⁻²⁾y⁴⁽⁻²⁾) /(x⁻²y) [ By the Power Rule: (aᵇ)ⁿ = aᵇⁿ ]
=> (x⁻⁶y⁻⁸) /(x⁻²y)
=> (x⁻⁶ · x² · y⁻⁸ · y⁻¹) [ By the Quotient Rule: aᵇ / aⁿ = a⁽ᵇ⁻ⁿ⁾ ]
=> (x⁻⁶⁺² y⁻⁸⁻¹) [ By the Product Rule: aᵇ × aⁿ = a⁽ᵇ⁺ⁿ⁾ ]
=> (x⁻⁴y⁻⁹)
Therefore,
The expression (x³y⁴)⁻²/(x⁻²y) is the same as x⁻⁴y⁻⁹

Suppose you went to Vegas and you will bet until you are broke. You start with $ 18 and bet $1 each time for the slot machine. The probability of winning is 0.0028 . Once you win, you earn $20 (net earnings are $10 in total considering $1 you paid to bet). Write a loop to simulate this and report the total number of bets you did until you are broke. Before running the loop, set the seed number equals to 77 .
Answers
If the random number is less than the winning probability of 0.0028, the player wins $20 and we add that to the amount variable.
Otherwise, the player loses $1 and we subtract that from the amount variable.
To simulate this scenario in Python.
Here's a possible implementation:
import random
# Set the seed number
random.seed(77)
# Initialize the starting amount and the number of bets
amount = 18
num_bets = 0
# Loop until the player runs out of money
while amount >= 1:
# Increment the number of bets
num_bets += 1
# Check if the player wins
if random.random() < 0.0028:
amount += 20 - 1 # The net earnings are $10
# Otherwise, the player loses $1
else:
amount -= 1
# Report the total number of bets
print(f"Total number of bets: {num_bets}")
In this implementation, we use the random module in Python to simulate the outcome of each bet.
We set the seed number to 77 to ensure that the results are reproducible.
We initialize the starting amount to $18 and the number of bets to 0. We then loop until the player runs out of money (i.e., the amount variable is less than $1).
Inside the loop, we increment the number of bets by 1 and simulate the outcome of the bet using random.
random() which returns a random float between 0 and 1.
If the random number is less than the winning probability of 0.0028, the player wins $20 and we add that to the amount variable.
Otherwise, the player loses $1 and we subtract that from the amount variable.
After the loop ends, we print the total number of bets.

Surface area leave in pie
Answers
The total surface area of the given figure is 320 units² respectively.
What is the Surface area?The quantity of space enclosing a three-dimensional shape's exterior is its surface area.
The area is a two-dimensional measurement of the size of a flat surface, whereas surface area is a three-dimensional measurement of the exposed surface of a solid object.
The main distinction between area and surface area is this.
So, the surface area of the cylinder: r = 3
[tex]A=\pi rh+2\pi r^{2}[/tex]
Now, calculate:
[tex]A=2\pi 3*10+2\pi 3^{2} \\A=245 units^{2}[/tex]
The surface area of the cone:
[tex]A = \pi r(r=h^{2} +r^{2} )[/tex]
Insert values as follows:
[tex]A=\pi r(3+\sqrt{4^{2} +3^{2} } )\\A=75.39822[/tex]
Rounding off: 75 units²
The total surface area of the given figure: [tex]75+245=320 units^{2}[/tex]
Therefore, the total surface area of the given figure is 320 units² respectively.
