Nehemiah wants to create a function to represent the change in his income over the past few months. Nehemiah estimates that the best fit linear function for the change in his income is ,y=2310+220x where y is his monthly income and x is the number of months.

Answer:

  (x -5)^2 +(y +4)^2 = 100

Step-by-step explanation:

The equation of a circle with center (h, k) that passes through point (a, b) is ...

 (x -h)^2 +(y -k)^2 = (a -h)^2 +(b -k)^2

For your given points, the equation is ...

  (x -5)^2 +(y +4)^2 = (-3-5)^2 +(2+4)^2 = 64 +36

  (x -5)^2 +(y +4)^2 = 100

The projected balance of cash at the end of August is $38,000. The correct option is D.

To calculate the projected balance of cash at the end of August, we need to consider the cash balance at the beginning of the month, cash collections, and cash payments for August.

Given that the cash balance on July 31 was $32,000.00, we start with this amount.

Cash collections for August are $52,000.00, which means this amount is added to the cash balance.

Next, we consider cash payments for August, which include purchases of direct materials and operating expenses. The total cash payments for August are $20,000 (purchases of direct materials) + $26,000 (operating expenses) = $46,000.00. This amount is subtracted from the cash balance.

Finally, we calculate the projected balance of cash at the end of August by adding the cash collections and subtracting the cash payments from the beginning cash balance:

Projected cash balance at the end of August = Beginning cash balance + Cash collections - Cash payments

= $32,000 + $52,000 - $46,000

= $38,000

Therefore, correct option is D.

The annual maintenance collected in 2014 will be $1,750,000.

To calculate the annual maintenance collected in 2014, we need to find the number of customers who will renew their maintenance contract and the number of customers who will pay for maintenance as a percentage of product sales in 2013.

Number of customers renewing maintenance in 2014 = 80% of $2,000,000 = $1,600,000

Number of customers paying for maintenance in 2014 = 75% of $2,000,000 = $1,500,000

So, the total annual maintenance collected in 2014 will be:

$1,600,000 + $1,500,000*10% = $1,750,000

Therefore, the annual maintenance collected in 2014 will be $1,750,000.

1. Variable manufacturing overhead rate variance

The formula Actual Hours × (Actual Rate - Standard Rate) is used to calculate the variable manufacturing overhead rate variance. This variance measures the difference between the actual variable manufacturing overhead cost incurred and the standard variable manufacturing overhead cost that should have been incurred, based on the standard rate per hour.

Variable manufacturing overhead rate variance = Actual Hours × (Actual Rate - Standard Rate)

The variable manufacturing overhead rate variance provides insight into how efficiently a company is utilizing its variable manufacturing overhead resources in terms of the rate per hour. A positive variance indicates that the actual rate paid per hour for variable manufacturing overhead was higher than the standard rate, resulting in higher costs. On the other hand, a negative variance suggests that the actual rate paid per hour was lower than the standard rate, leading to cost savings.

By analyzing this variance, management can identify areas where the company may be overspending or underspending on variable manufacturing overhead and take corrective actions accordingly, such as renegotiating supplier contracts or optimizing resource allocation.

We can say with 95% confidence that the true mean amount that women in the population spend dining out per week lies within the range of $91.74 to $108.26.

Based on the given information, we can calculate a 95% confidence interval for the mean amount that women in the population spend dining out per week. With a sample size of 25 and a standard error of $4, we can use the formula:

95% CI = sample mean +/- (critical value x standard error)

To find the critical value, we need to look up the t-distribution with degrees of freedom (df) = n-1 = 24 and a significance level of alpha = 0.05/2 = 0.025 (since we are interested in a two-tailed test). From a t-table or calculator, we find that the critical t-value is approximately 2.064.

Plugging in the values, we get:

95% CI = $100 +/- (2.064 x $4)
95% CI = $100 +/- $8.26
95% CI = ($91.74, $108.26)

Therefore, we can say with 95% confidence that the true mean amount that women in the population spend dining out per week lies within the range of $91.74 to $108.26. This means that if we were to repeatedly take random samples of 25 women and calculate their mean amount spent dining out, about 95% of the intervals we construct using this method would contain the true population mean.

According to the model, 18% of gross domestic product will go toward health care in the year 2026.

To find the year when 18% of gross domestic product (GDP) will go toward health care according to the given model, we need to solve the equation:

f(x) = 18

where f(x) represents the percentage of GDP going toward health care x years after 2006.

Given the model f(x) = 1.4 ln(x) + 13.8, we can substitute 18 for f(x):

1.4 ln(x) + 13.8 = 18

Subtracting 13.8 from both sides:

1.4 ln(x) = 4.2

Dividing both sides by 1.4:

ln(x) = 3

To solve for x, we can exponentiate both sides using the base e (natural logarithm):

e^(ln(x)) = e^3

x = e^3

Using a calculator, the approximate value of e^3 is 20.0855.

Therefore, according to the model, 18% of GDP will go toward health care in the year 2006 + x = 2006 + 20.0855 ≈ 2026 (rounded to the nearest year).

The following probabilities are:

P(+g, +a, +C, +S) = 0.4

P(+a) = P(+a, +g) + P(+a, -g) = (1.0 * 0.1) + (0.9 * 0.9) = 0.91

P(+g|+C) = 0.15

P(+g|+S, +C) = 0.769

P(+C|+g) = 0.06 / 0.1 = 0.6

To compute the probabilities requested, we will use the Bayes' network and the probability tables given.

Probability of having gene variation and allergy, having a cold and sneezing:

P(+g, +a, +C, +S) = P(S|+a, +C) * P(+a, +g) * P(+C)

P(S|+a, +C) = 1.0, from the table P(S|A, C)

P(+a, +g) = 1.0, from the table P(AG)

P(+C) = 0.4, from the table P(C)

Therefore,

P(+g, +a, +C, +S) = 1.0 * 1.0 * 0.4 = 0.4

Probability of having the gene variation:

P(+g) = 0.1, from the table P(G)

Probability of having the gene variation given that the person has a cold:

P(+g|+C) = P(+g, +C) / P(+C)

P(+g, +C) = P(+g) * P(+C|+g) = 0.1 * 0.6 = 0.06, from the table P(C|AG)

P(+C) = 0.4, from the table P(C)

Therefore,

P(+g|+C) = 0.06 / 0.4 = 0.15

Probability of having the gene variation given that the person sneezes and has a cold:

P(+g|+S, +C) = P(+g, +a, +C, +S) / P(+S, +C)

P(+g, +a, +C, +S) was computed in step 1, which is 0.4.

P(+S, +C) = P(S|+a, +C) * P(+a, +g) * P(+C) + P(S|-a, +C) * P(-a, +g) * P(+C)

= (1.0 * 1.0 * 0.4) + (0.2 * 0.9 * 0.4) = 0.52

P(+g|+S, +C) = 0.4 / 0.52 = 0.769

Probability of having cold given that the person has the gene variation:

P(+C|+g) = P(+C, +g) / P(+g)

P(+C, +g) = P(+C|+g) * P(+g) = 0.6 * 0.1 = 0.06, from the table P(C|AG)

P(+g) = 0.1, from the table P(G)

Answer: 2xy

Step-by-step explanation:

A procession typically has one-fourth of the participants with red hair, one-sixth with brown hair, and the remaining participants with black hair. 7/12 of the population has black hair.

We are given that 1/4 of the people have red hair and 1/6 of them have brown hair.

Let's add these fractions together to find the fraction of people who have either red or brown hair:

\(\\\frac{1}{4} + \frac{1}{6}\\ =\frac{3+2}{12} \\ =\frac{5}{12}\)

This means that 5/12 of the people have either red or brown hair.

Since the remaining people must have black hair, we can subtract this fraction from 1 to find the fraction of people who have black hair:

1 - 5/12

=12-5/12

= 7/12

Therefore, the fraction of people who have black hair is 7/12.

The work required to pump all the oil to the surface is 4.87 million ft-lb.  

The fuel oil tank is an upright cylinder with a circular top 12 feet below ground level.

Its dimensions are a radius of 6 feet and a height of 18 feet, with a current oil level of only 14 feet deep.

Calculate the work necessary to pump all of the oil to the surface, given that oil has a weight of 50 lb/ft³.

Work is equal to the force multiplied by the distance moved by the object along the force's direction (W = Fd).

The force is equal to the mass multiplied by the gravitational field strength (F = mg).

The mass is equal to the density multiplied by the volume (m = ρV).

Let's first calculate the volume of oil contained in the tank.

V = πr²h = π(6²)(14) = 504π cubic feet, where V is the volume, r is the radius, and h is the height.

Substituting the density of oil and the volume of oil into the mass equation, we get

m = ρV = (50 lb/ft³) (504π ft³) = 25200π lb

Next, calculate the weight of the oil.F = mg = (25200π lb) (32.2 ft/s²) = 811440 lb.

Substituting the force and the distance into the work formula, we get the work required.

W = Fd = (811440 lb) (12 ft) = 9737280 ft-lb = 4.87 million ft-lb (rounded to two decimal places).

The work required to pump all the oil to the surface is 4.87 million ft-lb.

The length of one side of the pyramid's base is 16 units. To find the length of one side of the pyramid's base, we can use the information given about the right triangle formed within the pyramid.

Let's denote the side length of the base as "b" units. According to the problem, one leg of the highlighted right triangle is from the center of the base to the apex of the pyramid, which is equal to the vertical height of the pyramid, given as 15 units. The other leg is from the center of the base to the edge of the base, and it is half the size of the side length of the pyramid's base, which is b/2 units. The hypotenuse of the right triangle represents the height of one of the triangular faces of the pyramid, given as 17 units.

Using the Pythagorean theorem, we can relate the lengths of the legs and the hypotenuse of the right triangle:

\((leg)^2 + (leg)^2 = (hypotenuse)^2\)

Substituting the given values into the equation, we have:

\((15)^2 + (b/2)^2 = (17)^2\)

Simplifying the equation:

\(225 + (b/2)^2 = 289\)

Subtracting 225 from both sides:

\((b/2)^2 = 289 - 225\)

\((b/2)^2 = 64\)

The missing value, rounded to the nearest hundredth, is approximately 54.46 degrees.

The equation sin ___ = 7/12 suggests that we need to find an angle whose sine is equal to 7/12. To determine the missing value, we can use the inverse sine function, also known as arcsine or sin^-1.

Using the inverse sine function, we can write the equation as ___ = sin^-1(7/12). Evaluating this expression with a calculator or a trigonometric table, we find that sin^-1(7/12) is approximately 54.46 degrees.

It's important to note that trigonometric functions have periodicity, meaning that there are multiple angles that have the same sine value. Therefore, there are other angles, such as 180 degrees minus 54.46 degrees, that also satisfy sin ___ = 7/12. However, when finding a single missing value, we typically consider the principal value within a specified range, often from -90 degrees to 90 degrees.

Thus, rounding to the nearest hundredth, the missing value that satisfies sin ___ = 7/12 is approximately 54.46 degrees.
