To find the number of baseball caps and sweatshirts sold, we can set up an equation using the given information and solve for the variables. The solution shows that 22 baseball caps and 132 sweatshirts were sold.

Let's solve this problem step by step:

Therefore, 22 baseball caps and 132 sweatshirts were sold.

The problem is solved by setting up equations based on the given information. Ron Co. sold 132 sweatshirts at $20 each and 22 baseball caps at $10 each to make a total of $2,860 in sales.

To solve the problem, let's define the variables representing the number of sweatshirts and caps sold. Let's say 's' equals the number of sweatshirts and 'c' equals the number of baseball caps.

We are given two pieces of information:

The price of a sweatshirt is $20, and the price of a cap is $10. The total sales can be expressed as the sum of the sales from sweatshirts and caps, which gives us the equation 20s + 10c = 2860.

Using the information that s = 6c, we can substitute 6c for s in the total sales equation to get 20(6c) + 10c = 2860. Simplifying this equation, we get 120c + 10c = 2860, which leads to 130c = 2860. Dividing both sides by 130 gives us c = 22.

Now, we can find the number of sweatshirts sold by substituting c into the equation s = 6c. So, s = 6(22) = 132.

Therefore, Ron Co. sold 132 sweatshirts and 22 baseball caps.

Final answer:

The outstanding balance on Joe Jay's mortgage after the first payment cannot be determined without the monthly payment amount. Typically the initial payments are mainly applied to interest, so the principal would remain close to the financed amount of $208,000.

Explanation:

Joe Jay made a 20% down payment on a $260,000 home, which equals $52,000 ($260,000 * 0.20). The remaining balance he would need to finance through a mortgage would be $260,000 - $52,000 = $208,000. To find out the balance outstanding after the first payment, we would typically use an amortization formula or a financial calculator, considering the 6.5% annual interest rate and the 25-year term of the mortgage. Unfortunately, without additional information such as the monthly payment amount, we cannot calculate the exact principal balance outstanding after the first payment. Generally, the first few payments in an amortization schedule primarily cover interest, so the principal would not change much from the initial $208,000.

Final answer:

The principal after the first payment has an outstanding balance of $206,830.79.

Explanation:

To find the principal after the first payment, we need to calculate the amount of the loan that remains after the down payment and the first payment.

Step 1: Calculate the down payment amount by multiplying the purchase price by the down payment percentage: $260,000 * 0.20 = $52,000.

Step 2: Calculate the loan amount by subtracting the down payment from the purchase price: $260,000 - $52,000 = $208,000.

Step 3: Calculate the monthly interest rate by dividing the annual interest rate by 12: 6.5% / 12 = 0.00542.

Step 4: Calculate the principal after the first payment by subtracting the monthly payment from the remaining loan balance: $208,000 - $1,169.21 = $206,830.79.

Therefore, the outstanding balance after the first payment is $206,830.79.

It will take Brandy 20 weeks to save enough money to buy the digital camera.

To find out how many weeks it will take for Brandy to save enough money for the camera, we can set up an equation:

Let x be the number of weeks it will take for Brandy to save enough money.

$15 * x = $300

Solving for x:

x = $300 / $15

x = 20

Therefore, it will take Brandy 20 weeks to save enough money to buy the digital camera.

Erin should buy 74 tiles to be safe.

Since Erin is buying floor tile to put in a room that is 10 ft. by 15 ft., and she has chosen tiles that are 18 in by 18 in., assuming that she needs to buy 10% extra to be safe, to determine how many tiles will she need to buy the following calculation must be performed:

The equality between feet and inches must be established, then the area of the room must be calculated, and then the area of each tile. Then, the area of the room must be divided by the area of the tile to know how many should be used.

Therefore, Erin should buy 74 tiles to be safe.

Determine the ticket price that leads to zero revenue by setting the equation equal to zero and solving for the variable which is $17.50

To solve this problem, we first need to express the revenue from ticket sales as a function of the number of $1.00 price increases. We can use the formula R = (50,000 - 3,500x) * (21 + x), where R represents the daily revenue and x represents the number of price increases.

N= Number of visitors and $P = price $R = Revenue

N = 50,000 - (P-15)*2500

R = N*P = 50,000P -2,500P^2 + 15*2500P

R = 87,500P -2,500P^2

dR/dP = 87,500 - 5000P = 0 for max

P = $17.50 for max revenue

Next, we can find the ticket price that maximizes the revenue by finding the vertex of the quadratic equation. The ticket price that leads to no revenue can be found by setting the daily revenue equal to zero and solving for x.

The analysis aims to see if there's a correlation between lawyers' height and salary, using statistical tests to determine if the null hypothesis—which states there is no relationship—should be rejected at a 5% significance level.

The purpose of this analysis is to discover whether there is a statistical relationship between the height of male lawyers and their salary five years after graduating from law school. To determine this, we can utilize statistical methods such as correlation and regression analysis. However, it should be noted that merely finding a correlation does not establish causation, and any findings would require a more robust analysis to conclude that height is a determinant factor in salary.

In part (a), if we were to perform the statistical test, we would calculate the correlation coefficient to establish the strength and direction of the relationship between height and salary. If the p-value from this test is less than the level of significance (5%), the null hypothesis would be rejected, suggesting that there is a relationship between height and salary.

The null hypothesis in part (a) states there is no relationship between the height of lawyers and their salary. Specifically, it asserts that any observed association in the sample data results from random variation and does not reflect the population of corporate lawyers.

Two algebraic expressions separated by an equal symbol in between them and with the same value are called equations.

Example = 2 x +4 = 12

here, 4 and 12 are constants and x is variable

A collection of constants, variables connected using one or more arithmetic operator is called an expression

Consider an equation to  prove 2.8 as a repeating fraction.

Let x = 2.8 repeating

Multiply both sides of the equation by 10 to get a whole number.

10 x = 28.8 repeating

Next, we subtract the original equation from the multiplied equation to eliminate the repeating part:

10 x - x = 28.8 repeating - 2.8 repeating

9 x = 26

Now, we can solve for x by dividing both sides of the equation by 9

x = [tex]\dfrac{26}{9}[/tex]

Therefore, the decimal number 2.8 repeating can be expressed as the fraction [tex]\dfrac{26}{9}[/tex].

To find the equation of the line with a slope of -5 that crosses the x-axis at (3,0), use point-slope form to get y = -5x + 15, which is the required equation.

To determine an equation for a function that has a slope of -5 and crosses the x-axis at (3,0), you can use the point-slope form of a linear equation: y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

Here, the slope m is -5 and the point on the line is (3,0). Plugging these values into the point-slope form, we get:

y - 0 = -5(x - 3)

This simplifies to:

y = -5x + 15

This equation represents a line with a slope of -5 that crosses the x-axis at the point (3,0), meeting all the conditions given in the question.

Answer:

The missing value of [tex]x =\frac{20}{7} =2 \frac{6}{7}[/tex]

Step-by-step explanation:  

The inverse variation is given by:  [tex]x \propto \frac{1}{y}[/tex]

Step-by-step explanation:

The probability that he will make at least one sale during the hour will be 0.766.

Frequency distribution of the percentage of successful outcomes that might occur in a certain number of trials with the same chance of success. If X~B(n, p), then the probability is given as

[tex]\rm P(X=x) = \ ^nC_x \times p^x \times (1-p)^{n - x}[/tex]

A telemarketer will make 25 calls in one hour. the probability of making a sale on any given call is .09.

Then the probability that he will make at least one sale during the hour will be given as,

P(x ≥ 1) = 1 - P(x = 1)

P(x ≥ 1) = 1 - ²⁵C₁ (0.09)¹ (1 - 0.09)²⁴

P(x ≥ 1) = 1 - 25 x 0.09 x 0.10399

P(x ≥ 1) = 1 - 0.233978

P(x ≥ 1) = 0.766

The probability that he will make at least one sale during the hour will be 0.766.
