the probability of picking a pitcher from the remaining cards is still 7/24. The probability that the next card Leslie looks at will be a pitcher is 7/24.

Leslie randomly looked at 24 cards out of 300, and she saw that 7 of them were pitchers. So, the probability of picking a pitcher from those 24 cards is 7/24. Since the remaining cards are still part of the same deck, and Leslie did not replace any of the cards she looked at, the probability of picking a pitcher from the remaining cards is still 7/24. Therefore, the probability that the next card Leslie looks at will be a pitcher is 7/24.

Step 1: Determine the total number of cards Leslie looked at, which is 24 (8 outfielders + 7 pitchers + 4 catchers + 5 infielders).
Step 2: Identify the number of pitchers, which is 7.
Step 3: Calculate the probability of picking a pitcher by dividing the number of pitchers by the total number of cards: 7 pitchers / 24 cards = 0.2917, or 29.17% when expressed as a percentage.

So, based on the data, the probability that the next card Leslie looks at will be a pitcher is approximately 29.17%.

The number n must be greater than or equal to 2.65 and less than 2.75 in order to round to 2.7 when rounded to one decimal place

If a number n rounded to one decimal place is 2.7, then we know that n lies between two numbers:

The lower bound is the number that is 0.05 less than 2.7, which is 2.65 (since the digit in the second decimal place is 5 or greater, we round up the last digit in the first decimal place).

The upper bound is the number that is 0.05 greater than 2.7, which is 2.75 (since the digit in the second decimal place is 5 or greater, we round up the last digit in the first decimal place).

Therefore, we can write the inequality as:

2.65 ≤ n < 2.75

This means that n must be greater than or equal to 2.65 and less than 2.75 in order to round to 2.7 when rounded to one decimal place.

For a balloon mortgage, the monthly payments are usually lower, but there is a final "balloon" payment due at the end of the term.

a. Property Taxes:

The assessed value of the building is $500,000, and the property tax rate is 2.415%. To calculate the property taxes, we multiply the assessed value by the tax rate:

Property taxes = Assessed value * Tax rate

Property taxes = $500,000 * 2.415% (convert percentage to decimal)

Property taxes = $500,000 * 0.02415

Property taxes = $12,075

Therefore, the property taxes on the assessed value of the building will be $12,075.

b. Monthly Mortgage Payment:

To calculate the monthly mortgage payment, we need to consider the loan amount, interest rate, and loan term. The down payment is 20%, so the loan amount will be 80% of the market value of the building:

Loan amount = Market value * (1 - Down payment percentage)

Loan amount = $457,350 * (1 - 20%) (convert percentage to decimal)

Loan amount = $457,350 * 0.8

Loan amount = $365,880

We can now use this loan amount, along with the mortgage interest rate and loan term, to calculate the monthly payment using the formula for a fixed-rate mortgage:

Monthly payment = (Loan amount * Monthly interest rate) / (1 - (1 + Monthly interest rate)^(-Total number of months))

The monthly interest rate is the annual interest rate divided by 12, and the total number of months is the loan term multiplied by 12.

Annual interest rate = 4.55% (convert percentage to decimal)

Monthly interest rate = 4.55% / 12

Loan term = 30 years

Total number of months = 30 * 12

Now, let's calculate the monthly payment:

Monthly payment = ($365,880 * Monthly interest rate) / (1 - (1 + Monthly interest rate)^(-Total number of months))

c. Total Interest Paid:

To calculate the total interest paid over the life of the loan, we multiply the monthly payment by the total number of months and subtract the loan amount:

Total interest paid = (Monthly payment * Total number of months) - Loan amount

d. Closing Costs:

The closing costs can vary, but a common range is between 2% and 5% of the purchase price. To calculate the range for closing costs, we'll use these percentages:

Minimum closing costs = Purchase price * 2%

Maximum closing costs = Purchase price * 5%

e. Balloon Mortgage Payment:

For a balloon mortgage, the monthly payments are usually lower, but there is a final "balloon" payment due at the end of the term. To calculate the monthly payment for the balloon mortgage, we'll use the loan amount, interest rate, and loan term:

Monthly payment = (Loan amount * Monthly interest rate) / (1 - (1 + Monthly interest rate)^(-Total number of months))

Now, let's calculate the monthly payment for the balloon mortgage.

Answer:

I'm not the best at explaining but here it is...

Step-by-step explanation:

on each side of a line, there are 2 angles. These angles match the ones on the other side of the line. So with that and what we know. We can figure it out.

m<1 is 40. M<4 is opposite of this angle witch makes it the same size. That makes m<4 alo 40.

m<3 is 140. M<2 is opposite of this angle making it the same. This makes m<2 also 140.

now we move down to the bottom 4 angles. These are the same as the top 4 making the values the same.

for a more simple view of the answers...

m<1 is 40

m<2 is 140

m<3 is 140

m<4 is 40

m<5 is 40

m<6 is 140

m<7 is 140

m<8 is 40

We can reject the null hypothesis and conclude that there is a significant difference in the average customer satisfaction ratings between Home Depot and Lowe's.

What is hypothesis?

A hypothesis is a proposed explanation or prediction that can be tested through empirical investigation.

To test the difference in the average customer satisfaction rating for Home Depot and Lowe's, we can perform a two-sample t-test. Let's go through the steps of conducting the hypothesis test:

Step 1: State the hypotheses:

Null Hypothesis (H₀): The average customer satisfaction rating for Home Depot is equal to the average customer satisfaction rating for Lowe's.

Alternative Hypothesis (H₁): The average customer satisfaction rating for Home Depot is different from the average customer satisfaction rating for Lowe's.

Step 2: Set the significance level (α):

Let's assume a significance level of α = 0.05. This means we want to have strong evidence to reject the null hypothesis if the p-value is less than 0.05.

Step 3: Collect the data and calculate the sample statistics:

We have the following customer satisfaction ratings:

Home Depot: 79, 81

Lowe's: 72, 78, 79, 76, 72

To calculate the sample statistics, we need to find the sample means and sample standard deviations for Home Depot and Lowe's.

Sample mean of Home Depot [tex](\bar x_1)[/tex] = (79 + 81) / 2 = 80

Sample mean of Lowe's [tex](\bar x_2)[/tex] = (72 + 78 + 79 + 76 + 72) / 5 = 75.4

To calculate the sample standard deviations, we need to find the differences between each rating and the respective sample mean, square the differences, sum them up, divide by n-1, and then take the square root.

Home Depot: [(79-80)² + (81-80)²] / (2-1) = 1 / 1 = 1

Lowe's: [(72-75.4)² + (78-75.4)² + (79-75.4)² + (76-75.4)² + (72-75.4)²] / (5-1) = 16.8 / 4 = 4.2

Step 4: Calculate the test statistic:

To calculate the test statistic, we use the formula:

[tex]t = (\bar x_1 - \bar x_2) / \sqrt((s_1^2/n_1) + (s_2^2/n_2))[/tex]

Substituting the values:

[tex]t = (80 - 75.4) / \sqrt{((1^2/2) + (4.2^2/5))}\\\\t = 4.6 / \sqrt(0.5 + 1.68)[/tex]

t ≈ [tex]4.6 / \sqrt(2.18)[/tex]

t ≈ 4.6 / 1.476

t ≈ 3.116

Step 5: Determine the p-value:

We need to find the p-value associated with the calculated test statistic. Since this is a two-sided test, we need to find the probability of observing a test statistic as extreme as t = 3.116 or more extreme in either tail of the t-distribution.

Using a t-distribution table or statistical software, the p-value is found to be p ≈ 0.021.

Step 6: Make a decision:

Compare the p-value to the significance level. Since the p-value (0.021) is less than the significance level (0.05), we have enough evidence to reject the null hypothesis.

Step 7: State the conclusion:

Based on the sample data, there is sufficient evidence to conclude that the average customer satisfaction rating for Home Depot is different from the average customer satisfaction rating for Lowe's at a significance level of 0.05.

Therefore, we can reject the null hypothesis and conclude that there is a significant difference in the average customer satisfaction ratings between Home Depot and Lowe's.

To find the probability that a randomly selected household owns neither a cell phone nor an iPad, we need to subtract the probability of owning at least one device from 1.

First, we can find the percentage of households that own at least one device:  65% own a cell phone , 23% own an iPad , 12% own both
To find the percentage that own at least one device, we add the percentages of cell phone and iPad owners and then subtract the percentage that own both:  65% + 23% - 12% = 76%
Therefore, 76% of households own at least one device.
To find the percentage of households that own neither device, we subtract 76% from 100%: 100% - 76% = 24%
So the probability that a randomly selected household owns neither a cell phone nor iPad is 24%.

In summary, the three paragraph answer is: The probability that a randomly selected household owns neither a cell phone nor iPad in a certain town is 24%. Therefore, the probability that a randomly selected household owns neither a cell phone nor an iPad is 100% - 76%, which equals 24%.

Based on the confidence interval of (0.42, 0.48), the claim that is not supported is that less than 42% of all women do not find time to focus on their own health. This is because the lower bound of the interval is 0.42, indicating that at worst, 42% of all women do not find time to focus on their own health. Therefore, any claim that suggests a lower percentage is not supported by the confidence interval.

On the other hand, the confidence interval does support claims that suggest the percentage of women who do not find time to focus on their own health is at least 42% and no more than 48%. For example, a claim that states "between 42% and 48% of all women do not find time to focus on their own health" is supported by the confidence interval.

It is important to note that the confidence interval does not tell us anything about the actual percentage of women who do not find time to focus on their own health.

(b) Juliet spends 7 hours coaching lacrosse and 17 hours coaching field hockey each day.

To model the situation, we can define the following variables:

Let x be the number of hours Juliet coaches lacrosse.

Let y be the number of hours Juliet coaches field hockey.

From the given information, we can create a system of equations:

The total coaching hours: x + y = 24

The field hockey practice duration: y = 2x + 3

To determine how many hours Juliet spends coaching each sport, we can solve the system of equations.

First, we'll substitute the value of y from equation 2 into equation 1:

x + (2x + 3) = 24

3x + 3 = 24

3x = 21

x = 7

Now, we can substitute the value of x back into equation 2 to find y:

y = 2(7) + 3

y = 14 + 3

y = 17

Juliet spends 7 hours coaching lacrosse and 17 hours coaching field hockey each day.

To verify our solution, we can check if the total coaching hours add up to 24:

7 + 17 = 24

To find the maximum value of a and the minimum value of b, we need to solve the equation 9+9x-x²-x³ = k for x and then determine the range of values for k where the equation has only one solution.

First, we can rearrange the equation to get:

x³ + x² - 9x - (k - 9) = 0

We can then use the rational root theorem to find the possible rational roots of this polynomial equation. The possible rational roots are of the form p/q, where p is a factor of the constant term (k - 9) and q is a factor of the leading coefficient (1). The factors of (k - 9) are ±1, ±3, ±(k-9), and the factors of 1 are ±1. So the possible rational roots are:

±1, ±3, ±(k-9), ±(k-9)/3

We can test each of these possible roots by plugging them into the equation and checking if the result is zero. After testing each possible root, we find that the only root that works is x = 3. Therefore, the equation has only one solution when x = 3.

To determine the range of values for k where the equation has only one solution, we can substitute x = 3 into the equation:

9 + 9(3) - 3² - 3³ = k

Simplifying this, we get:

k = -9

So the equation has only one solution when k = -9. Now, we need to find the maximum value of a and the minimum value of b for this value of k.

For k < -9, the equation has no real solutions, since the equation is a cubic polynomial with a negative leading coefficient, which means it has a local maximum and a local minimum. Therefore, the maximum value of a is -9.

For k > -9, the equation has three real solutions, since the equation is a cubic polynomial with a negative leading coefficient, which means it has a local maximum and a local minimum, and crosses the x-axis three times. Therefore, the minimum value of b is -9.

So the maximum value of a is -9 and the minimum value of b is -9.
