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%.

(a) The system of equations that models the situation is:

x + y = 24

y = 2x + 3

(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

The sum is indeed 24, confirming that our solution is correct.

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.

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.

Answer:

To compute the average speed, multiply the total distance travelled by the whole time spent. There's a formula for speed, time and distance

Travel distance aboard the pterodactyl = 10 mph x 3 hours = 30 miles

Distance travelled on the spinosaurus = 2 miles x 1 hour = 2 miles

30 miles + 2 miles = 32 miles total distance travelled

Total time required = 3 hours + 1 hour = 4 hours

Average speed = total distance travelled divided by the total time taken = 32 miles divided by 4 hours = 8 mph

As a result, our average speed is 8 mph.

Answer:

the solution points for the system of equations are (3, 25) and (-7/2, -7).

Step-by-step explanation:

We can solve this system of equations using substitution or elimination. Here, we will use the substitution method:

Substitute y = 2x^2 + 5x - 10 into the second equation:

4x - (2x^2 + 5x - 10) = -11

Simplifying the left side of the equation:

4x - 2x^2 - 5x + 10 = -11

Rearranging the terms:

2x^2 - x + 21 = 0

Using the quadratic formula:

x = (-(-1) ± sqrt((-1)^2 - 4(2)(21))) / 2(2)

x = (1 ± sqrt(169)) / 4

x = (1 ± 13) / 4

Simplifying:

x = 3 or x = -7/2

Now, substitute each value of x back into one of the original equations to find the corresponding value(s) of y:

For x = 3:

y = 2(3)^2 + 5(3) - 10 = 25

So one solution point is (3, 25).

For x = -7/2:

y = 4(-7/2) + 11 = -7

So the other solution point is (-7/2, -7).

Therefore, the solution points for the system of equations are (3, 25) and (-7/2, -7).

Answer:

√y = ¼ x² + 2

y = (¼ x² + 2)²

Step-by-step explanation:

dy / dx = x √y

Separate the variables:

dy / √y = x dx

Change radical to exponent:

y^-½ dy = x dx

Integrate both sides using power rule:

2 y^½ = ½ x² + C

2√y = ½ x² + C

Substitute initial condition:

2√9 = ½ (2)² + C

6 = 2 + C

C = 4

Therefore:

2√y = ½ x² + 4

√y = ¼ x² + 2

y = (¼ x² + 2)²

The store keeper used 125 pounds of flour worth $2.40 per pound and 175 pounds of flour worth $3 per pound to get 300 pounds of mixed flour.

The assertion that two expressions are equal when they are connected by the equals sign ("="), is the mathematical definition of an equation. As an example, 2x - 5 = 13. The equations in this example are 2x - 5 and 13. The symbol "=" links these two expressions together.

Let x be the number of pounds of the flour worth $2.40 per pound, and y be the number of pounds of the flour worth $3 per pound. Since the store keeper wants to end up with 300 pounds of flour, we have:

x + y = 300

We also know that the store keeper wants to sell the mixed flour for $2.05 per pound. This means that the total cost of the flour (x pounds at $2.40 per pound, plus y pounds at $3 per pound) must be equal to:

300 pounds × $2.05 per pound = $615

In other words:

2.40x + 3y = 615

Two equations with two unknowns are now present:

x + y = 300

2.40x + 3y = 615

We can find x and y using algebra. One way to do this is to solve the first equation for x:

x = 300 - y

We can then substitute this expression for x into the second equation:

2.40(300 - y) + 3y = 615

Expanding the parentheses and simplifying, we get:

720 - 2.4y + 3y = 615

0.6y = 105

y = 175

So, the store keeper used 175 pounds of flour worth $3 per pound. To find the amount of flour worth $2.40 per pound, we can substitute y = 175 into the equation x + y = 300:

x + 175 = 300

x = 125

Therefore, the store keeper used 125 pounds of flour worth $2.40 per pound and 175 pounds of flour worth $3 per pound to get 300 pounds of mixed flour.

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.

Answer:

m∠B = 11°

Step-by-step explanation:

When two angles are complementary, the sum of the measures equals 90° (the two angles form a right angle together)

Step 1:  Therefore, we can find x by making the sum of the measures of angles A and B equal to 90:

m∠A + m∠B = 90

4x - 13 + x - 12 = 90

5x - 26 = 90

5x = 115

x = 23

Step 2:  Now, we can plug in 23 for x in the equation representing m∠B:

m∠B = x - 12

m∠B = 23 - 12

m∠B = 11°

Other Examples:  There are many ways to have two complementary angles, where none of the two angles are 0 or 90, including (1° + 89°), (2° + 88°) (3° + 87°), ..., (44° + 46°)

The coordinates of point K can be given by (-1/4, 5/8).

What are cartesian coordinates?

Cartesian coordinates are the values on a graph that can be used to show the location of a point on the graph.

The coordinates of point K can be found as follows:

There are 4 lines between 0 and -1 on the x-axis which divide it into 4 equal parts.

Point K lies on the first line. This means that the x-coordinate of the point is -1/4.

There are 8 lines between 0 and 1 on the y-axis which divide it into 8 equal parts.

Point K lies on the fifth line. This means that the y-coordinate of the point is 5/8.

From this, we can understand that the coordinates of the point K on the graph can be given by (-1/4, 5/8).

Therefore, the coordinates of point K can be given by (-1/4, 5/8).
