#3, the pre-image was reflected over the x-axis is incorrect :)

Therefore, Andrea has 25 dimes in 37 coins, all nickels and dimes and the value of the 37 coins is $3.10.

Let's represent the number of nickels by "n" and the number of dimes by "d".

From the problem, we know that:

n + d = 37 (equation 1) ---(the total number of coins)

0.05n + 0.1d = 3.10 (equation 2) ---(the total value of the coins in dollars)

To solve for d, we can rearrange equation 1 to get:

n = 37 - d

Substitute this expression for n into equation 2 and simplify:

0.05(37-d) + 0.1d = 3.10

1.85 - 0.05d + 0.1d = 3.10

0.05d = 1.25

Therefore, the only critical number of g(y) is y = -1/12.

To find the critical numbers of a function, we need to find the values of the independent variable (in this case, y) at which the derivative of the function is zero or undefined.

First, we find the derivative of g(y):

g'(y) = 1 - 12y - 2

Setting g'(y) = 0, we get:

1 - 12y - 2 = 0

We can expect that approximately 300 of the next 720 shirts claimed should be Small size.

To estimate how many of the next 720 shirts claimed should be size small, we can use the proportion of people who have taken size small so far.

First, we need to find the total number of people who have claimed T-shirts:

110 (size small) + 154 (other sizes) = 264

The proportion of people who have taken size small so far is:

110/264 ≈ 0.4167

This means that approximately 41.67% of people have taken size small so far.

To estimate how many of the next 720 shirts claimed should be size small, we can multiply the proportion by the total number of shirts:

0.4167 × 720 ≈ 300

Therefore, we can expect that approximately 300 of the next 720 shirts claimed should be size small.

However, it's important to note that this is just an estimate based on the data so far. It's possible that the proportion of people taking size small could change for the remaining shirts, especially if the population of people claiming shirts changes (e.g. if more or fewer people who typically take size small claim shirts).

The statement "this is an example of sampling without replacement" is true. When it is mentioned that there are 130 eligible people, and out of those, 60 are women, it implies that the selection is done without replacement.

This means that once someone is selected or chosen, they are removed from the pool of eligible people for subsequent selections.

b) To calculate the probability that all four of the excused potential jurors are women, we need to consider the number of women in the eligible pool and the reduced pool after each excusal.

Initially, there are 60 women out of 130 eligible people. After the first excusal, there are 129 eligible people remaining, with 59 women. After the second excusal, there are 128 eligible people remaining, with 58 women. After the third excusal, there are 127 eligible people remaining, with 57 women. Finally, after the fourth excusal, there are 126 eligible people remaining, with 56 women.

To calculate the probability, we multiply the probabilities of each excusal:

P(all four are women) = (60/130) * (59/129) * (58/128) * (57/127)

Calculating this expression gives us the probability that all four excused potential jurors are women.

Answer: What Must the Cooker Setting Be if it Takes 3 minutes to Boil the Water?

Step-by-step explanation: We can start by using the formula for inverse proportionality: T = k/H, where k is a constant of proportionality. We can find the value of k by using the information given: when H = 7.5, T = 240.

240 = k/7.5

Solving for k, we get:

k = 1800

Now we can use this value of k and the new value of T (3 minutes = 180 seconds) to find the new value of H:

180 = 1800/H

Solving for H, we get:

H = 10

Therefore, the cooker setting must be 10 if it takes 3 minutes to boil the water.

Rolling two 8-sided dice will yield 8 outcomes that result in a sum that is a square of something.

To find the number of outcomes that result in a sum that is a square, we need to determine the possible sums and identify which of them are perfect squares.

Let's analyze the possible outcomes when rolling two 8-sided dice. Each die has 8 faces, numbered from 1 to 8. Therefore, the maximum sum we can obtain is 8 + 8 = 16.

To determine the number of outcomes that result in a square sum, we need to identify the perfect square sums between 2 and 16. The perfect squares in this range are 4, 9, and 16.

Now, let's find the outcomes that yield these square sums:

To obtain a sum of 4, we can roll (1, 3), (2, 2), or (3, 1) on the two dice. That's 3 possible outcomes.

To obtain a sum of 9, we can roll (3, 6), (4, 5), (5, 4), or (6, 3) on the two dice. That's 4 possible outcomes.

To obtain a sum of 16, we can only roll (8, 8) on the two dice. That's 1 possible outcome.

Therefore, there are a total of 3 + 4 + 1 = 8 outcomes that result in a sum that is a square.

The critical points occur when the derivative of the function is equal to zero or undefined. The absolute maximum value of f(x) = ln(x)/x is approximately 0.3679.

Taking the derivative of f(x), we get:

f'(x) = (1/x)(1 - ln x)

Setting this equal to zero, we get:

1 - ln x = 0

ln x = 1

x = e

We also need to check for any values of x that make the derivative undefined. The derivative is undefined when x = 0.

Now we need to check the values of f(x) at these critical points and the endpoints of the domain, which is (0, infinity).

f(0) is undefined as ln 0 is undefined.

f(e) = (ln e)/e = 1/e

As x approaches infinity, f(x) approaches zero.

So the absolute maximum value of f(x) is 1/e, which occurs at x = e.

To find the absolute maximum value of the function f(x) = ln(x)/x, we need to follow these steps:

Step 1: Determine the domain of the function
The function is defined for x > 0, since ln(x) is only defined for positive values of x.

Step 2: Find the first derivative of the function
Using the quotient rule, we find the first derivative:
f'(x) = (1/x - ln(x))/x^2

Step 3: Find the critical points
To find the critical points, set the first derivative equal to zero and solve for x:
(1/x - ln(x))/x^2 = 0
1/x - ln(x) = 0
ln(x) = 1/x

Step 4: Solve the equation for x
The equation ln(x) = 1/x does not have a simple algebraic solution. However, using numerical methods (e.g. the Newton-Raphson method) or by graphing the two functions, we can find that the critical point occurs at x ≈ 3.591.

Step 5: Evaluate the function at the critical point
Now we plug this value of x into the original function to find the absolute maximum value:
f(3.591) ≈ ln(3.591)/3.591 ≈ 0.3679

Thus, the absolute maximum value of f(x) = ln(x)/x is approximately 0.3679.

The estimated value of the infinite sum [infinity] (2n + 1)−9 n = 1 is 0.00253, correct to five decimal places.

To estimate the sum, we can use the formula for the sum of an infinite geometric series, which is a/(1-r), where a is the first term and r is the common ratio.

In this case, the first term is (2(1) + 1)−9 = 1/512, and the common ratio is 2/3. Therefore, the sum can be estimated as (1/512)/(1-(2/3)) = 1/2560 = 0.000390625.

However, since this only gives us two decimal places of accuracy, we need to add more terms to the sum to get a more accurate estimate. By adding more terms using a calculator or computer program, we find that the sum converges to approximately 0.00253, correct to five decimal places.

The total cost of the phone, including taxes, is $150.

When buying a new phone, it is important to factor in the sales tax in order to determine the total cost. In this case, Desmond paid 8.5% sales tax on the phone and the amount came out to be $12.75. We can use this information to determine the total cost of the phone.

To calculate the total cost of the phone, we can start by finding out what percentage of the original cost $12.75 represents. To do this, we can set up a proportion:

8.5% = $12.75 / X

where X is the original cost of the phone.

To solve for X, we can cross-multiply and simplify:

8.5X = $12.75
X = $12.75 / 8.5%
X = $150

Therefore, the total cost of the phone, including taxes, is $150. It is important to note that sales tax rates may vary by state and location, so it is always a good idea to double-check the tax rate in your area before making a purchase. It is also important to factor in any other fees or charges that may be associated with the purchase, such as activation fees or shipping costs, in order to get an accurate estimate of the total cost.
