Final answer:

To determine the weight of 1 1/9 cubic feet of water, convert the mixed number to an improper fraction and multiply by the weight per cubic foot, resulting in approximately 77.16 pounds.

Explanation:

The student is asking to calculate the weight of 1 1/9 cubic feet of water given that the weight of water is 62 1/2 lb per cubic foot. To find the weight of the water, we multiply the volume by the weight per unit volume:

Convert 1 1/9 to an improper fraction: 1 1/9 = 10/9.

Multiply 10/9 cubic feet by 62.5 lb/ft³ (weight of water per cubic foot).

Calculate: (10/9) × 62.5 = 694.44/9 ≈ 77.16 lb.

Hence, the weight of 1 1/9 cubic feet of water is approximately 77.16 pounds.

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.

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]

Now convert this into an equation we must multiply the constant variation k we get,

[tex]x =\frac{k}{y}[/tex]

To find the value of k;

use the coordinates (5,4) , where x =5 and y =4

then,

[tex]5=\frac{k}{4}[/tex] or

[tex]k =5 \times 4[/tex]

On Simplify, we get:

k = 20

the equation become:  [tex]x=\frac{20}{y}[/tex]

When y =7 we have;

[tex]x= \frac{20}{7}[/tex]  

(x ,7) = [tex](\frac{20}{7} , 7)[/tex]

therefore, the missing value x is, [tex]x =\frac{20}{7} =2 \frac{6}{7}[/tex]

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.

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.

By bringing 100 bottles to the shop, you will receive 10 drinks.

The students question relates to a mathematical conversion problem, where empty bottles are exchanged for drinks at a bottle shop. If the conversion rate is 10 empty bottles for 1 drink, then by bringing 100 bottles, we can set up a simple division:

Number of bottles: 100

Conversion rate: 10 bottles per drink

To find out how many drinks you can get for 100 bottles, we divide the total number of bottles by the conversion rate:

Divide 100 (bottles) by 10 (bottles per drink).

100 / 10 = 10

Therefore, by bringing 100 bottles to the shop, you will receive 10 drinks.

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.

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.

We can use long division in finding the remainder.

Place the divisor which is 41, outside the long division sign, and 694 under the long division sign as shown in the diagram.

41 goes into 694 16 times.

Write the 16 on top of the long division sign.

Multiply the 16 by 41, to obtain 656

Write the 656 below the 694 as in the diagram.

Subtract 656 from 694 to obtain 38.

Since 41 is more than 38 , we cannot proceed.

Hence,

[tex]\frac{694}{41}=16\:\:Remainder\:\:38[/tex]

Therefore the remainder is 38

The quotient is 16, and the remainder is 38.

We have,

To find the quotient and remainder when dividing 694 by 41, we can perform the division and observe the results.

Now,

41 x 16 = 656

And,

694 - 656 = 38

This means,

694 divided by 41 is equal to 16 with a remainder of 38.

Therefore,

The quotient is 16, and the remainder is 38.

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 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.
