The modification that would have to  result in a net worth of $100,000 is: adding $1,000 in credit card debt. Option D

They currently have $101,000 in assets.

We have the value of the automobile plus the value of the recreational vehicle.

110000+27000 = 137000

When the medical expenses are subtracted from the net assets, we have

137000-8700 = 128300

When the loan sum is subtracted from net value, we have

128300-80000 = 48300

Savings and net wealth together provide us

48300+5000 = 53300

Retirement money added to net worth gives us

53000+50000 = 103300

After deducting the credit card debt from net value, we have

103300-2300 = 101000

We deduct $1,000 from this to create $100,000. Therefore, choice D is the best one.

The best buy is at the campus canteen. The solution has been obtained by using arithmetic operations.

What are arithmetic operations?

According to mathematicians, all real numbers may be described by the four basic operations, often known as "arithmetic operations." The phrases quotient, product, sum, and difference are produced by the four mathematical operations of division, multiplication, addition and subtraction, respectively.

We are given that a can of tab costs Rs. 7.20 at Timber City.

So, the cost of 6 packs will be

6 (7.20) = Rs. 43.20

But, on promotion, the cost is Rs. 39.60.

So, the discount is

D = Rs. 43.20 - Rs. 39.60

D = Rs. 3.60

Similarly,

A can of tab in the campus canteen costs Rs. 7.50.

So, the cost of 6 packs will be

6 (7.50) = Rs. 45

But, on promotion, the cost is Rs. 39.

So, the discount is

D = Rs. 45 - Rs. 39

D = Rs. 6

Hence, the best buy is at the campus canteen.

Step-by-step explanation:

The average intensity of radiation between 10 meters and 50 meters from the source can be found using the following formula:

Average Intensity = (1 / (50 - 10)) * (Integral of r(x) from x=10 to x=50)

Using the formula for r(x), the integral of r(x) between 10 and 50 can be found as:

Integral of r(x) = -k * ln(x) evaluated at x = 50 and x = 10

Therefore, the average intensity of radiation between 10 and 50 meters from the source is given by:

Average Intensity = (1 / (50 - 10)) * (-k * (ln(50) - ln(10)))

This simplifies to:

Average Intensity = (1 / 40) * (-k * ln(5))

This is equivalent to choice c.

Average Intensity = 1/40 (-k/50 + k/10).

The number of food items they need to have on hand is:

Nachos = 1165

Hamburgers = 1700

Chicken strips = 50

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of fans surveyed = 250

Nachos= 58,

Hamburgers = 85

Chicken strips = 33

The percentage of each item.

Nachos= 58/250 x 100 = 23.2%

Hamburgers = 85/250 x 100 = 34%

Chicken strips = 33/250 x 100 = 13.2%

Now,

If,

Number of fans surveyed = 5000

Nachos = 23.2% of 5000 = 23.3/100 x 5000 = 1165

Hamburgers = 34% of 5000 = 34/100 x 5000 = 1700

Chicken strips = 13.2% of 5000 = 13.2/100 x 5000 = 50

Thus,,

Nachos = 1165

Hamburgers = 1700

Chicken strips = 50

x cube minus fourteen is equal to sixty-eight

The p-value from the data is 0.5289

To test whether the average score improvement of the GRE prep company's students is different than 100, we can use a two-sided t-test.

First, we need to set up our null and alternative hypotheses:

Null hypothesis (H0): The true mean score improvement of the GRE prep company's students is equal to 100.

Alternative hypothesis (Ha): The true mean score improvement of the GRE prep company's students is different than 100.

We will use a significance level of α = 0.05, which means we will reject the null hypothesis if the p-value is less than 0.05.

Next, we can calculate the sample mean and sample standard deviation of the data:

Sample mean (x) = 98.16

Sample standard deviation (s) = 8.88

We have a small sample size (n = 10) and the population standard deviation is unknown, so we will use a t-test. The t-statistic for a two-sided test is given by:

t = (x - μ) / (s / sqrt(n))

where μ is the hypothesized population mean (in this case, 100).

Substituting the values, we get:

t = (98.16 - 100) / (8.88 / sqrt(10)) = -0.655

Using a t-table with 9 degrees of freedom (n-1), we find that the two-tailed p-value for t = -0.842 is 0.5289.

Since the p-value (0.5289) is greater than the significance level (0.05), we fail to reject the null hypothesis. We do not have sufficient evidence to conclude that the true mean score improvement of the GRE prep company's students is different than 100.

Therefore, based on the given data, we cannot reject the claim of the GRE prep company that the average score improvement of their students is equal to 100.

The height of the hyperbolic vase is 5.12 * 2 = 10.24 inches.

What is a hyperbola?

A hyperbola is a particular kind of smooth curve that lies in a plane and is classified by its geometric characteristics or by equations for which it is the solution set. A hyperbola is made up of two mirror images of one another that resemble two infinite bows. These two sections are known as connected components or branches. A plane and both halves of a double cone connect to form a hyperbola, which is an open curve with two branches. The hyperbola will be symmetrical regardless of whether the plane is perpendicular to the cone's axis or not.

The eccentricity formula for a hyperbola is

[tex]e = \sqrt{1+\frac{b^2}{a^2} }[/tex]

e = 2.5

Given width at the narrowest point is 4 inches.

So the  value of a from the below figure is

a = ±2

So we can find b from the above eccentricity formula

2.5  = [tex]\sqrt{1+\frac{b^2}{2^2} }[/tex]

6.25 = 1 + b²/4

b²/4 = 5.25

b² = 21

b = ±4.6

So the equation of the hyperbola is

[tex]\frac{x^2}{a^2} - \frac{y^2}{b^2} = 1[/tex]

[tex]\frac{x^2}{4} - \frac{y^2}{21} = 1[/tex]

Now we are asked to find the height of the vase

The width at the top is 6 inches.

So take x = 3

Then we can find y from the above equation

[tex]\frac{3^2}{4} - \frac{y^2}{21} = 1[/tex]

y² = 26.25

y = 5.12 inches

Therefore the height of the hyperbolic vase is 5.12 * 2 = 10.24 inches.

-2W + 6 is The opportunity cost of 1 coconut is ½ bundle of firewood.

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

For Alice:

In the amount of time it takes to gather a bundle of firewood, Alice could have gathered (1/2) * 6 = 3 coconuts. Thus, the opportunity cost of one bundle of firewood is 3 coconuts.

The opportunity cost of 12 coconuts is 4 bundles of firewood.

Alice can gather 12 coconuts in 8 hours. If she were to gather firewood instead during these 8 hours then she would be able to gather 4 bundles of firewood

Therefore, when she chooses to gather 12 coconuts she is giving up 4 bundles of firewood.

Denoting coconuts through C and firewood through W, we are able to discover the equation for the PPF through graphing directly, or through noting that if all time is spent amassing wood, she will be able to accumulate four bundles of wood, so the W intercept is four.

Since the opportunity cost of a bundle of wood is 3 coconuts, the coefficient on C will be -1/3.

Therefore, we have W = (-1/3)C + 4, or equivalently C = -3W + 12.

(Alice’s PPF is plotted below in the solution to part (c).)

For Bob:

Since Each bundle of firewood takes as long as gathering 2 coconuts, the opportunity cost of one bundle of firewood is 2 coconuts.

The opportunity cost of 1 coconut is ½ bundle of firewood. Repeating the procedure from before, we find Bob’s PPF can be expressed by either W
