Jazz Corporation owns 10% of the Williams Corp. stock. Williams distributed a $23,000 dividend to Jazz Corporation. Jazz Corp.'s taxable income (loss) before the dividend was ($3,300). What is the amount of Jazz's dividends received deduction on the dividend it received from Williams Corp.?

Answers

The DRD for Jazz Corporation on the dividend it received from Williams Corp. is $4,000.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

To calculate the dividends received deduction (DRD) for Jazz Corporation on the dividend it received from Williams Corp., we need to determine the taxable income limit for the deduction.

The taxable income limit is based on the percentage of ownership in the company. Since Jazz Corporation owns 10% of Williams Corp. stock, the taxable income limit is 50% of its taxable income, or $4,000 ($8,000 x 50%).

The DRD is then calculated as the lesser of the dividend received or the taxable income limit. In this case, Jazz Corporation received a dividend of $12,900, which exceeds the taxable income limit of $4,000.

Therefore, the DRD for Jazz Corporation on the dividend it received from Williams Corp. is $4,000.

What is normal distribution?

Normal distribution, also known as Gaussian distribution, is a probability distribution that is commonly used in statistics, mathematics, and the natural sciences to describe real-valued random variables whose distributions are not known.

To find the probability that a randomly selected x-value from a normal distribution with a mean of 48 and a standard deviation of 7 is between 34 and 55, we need to standardize the values using the z-score formula:

z = (x - μ) / σ

where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

For x = 34:

z = (34 - 48) / 7 = -2

For x = 55:

z = (55 - 48) / 7 = 1

We can use a standard normal distribution table or a calculator to find the area under the standard normal distribution curve between z = -2 and z = 1. This area represents the probability that a randomly selected x-value from the given normal distribution is between 34 and 55.

Using a standard normal distribution table, we can find the probabilities as follows:

P(z < -2) = 0.0228 (from the table)

P(z < 1) = 0.8413 (from the table)

Therefore, the probability that a randomly selected x-value from the given normal distribution is between 34 and 55 is:

P(-2 < z < 1) = P(z < 1) - P(z < -2) = 0.8413 - 0.0228 = 0.8185

So, the probability is approximately 0.8185 or 81.85%.

What are algebraic equations?

An algebraic equation is a mathematical expression that includes one or more variables and mathematical operations such as addition, subtraction, multiplication, and division. The equation asserts that two expressions are equal.

The goal in solving an algebraic equation is to determine the value(s) of the variable(s) that make the equation true. Algebraic equations are used to solve problems in various fields such as physics, engineering, economics, and finance.

In the equation 3s + 135 = 4.5(s + 10), the expression (s + 10) represents the total number of rolls sold (small and large).

To see why, let's break down the equation:

3s represents the total amount earned from selling small rolls (since the

club earns $3.00 for every small roll sold).

4.5(s + 10) represents the total amount earned from selling all the rolls (small and large). The (s + 10) part represents the total number of rolls sold, since the club sold 10 more large rolls than small rolls, which is represented by adding 10 to the number of small rolls sold (s).

Therefore, the correct answer is (C) the total number of rolls sold (small and large).

A finite set of equations for which common solutions are sought is referred to as a set of simultaneous equations, often known as a system of equations or an equation system.

Let's look at the first one, we can rewrite it as:

y = 2x + 3

y = -x - 3

So, the slopes are different, meaning that we have one solution, so this system is consistent and independent.

Now let's look at the second system, we can rewrite it as:

y = 3x - 2

y = 3x + 2

Here both lines have the same slope, so the lines never do intersect, meaning that the system is inconsistent and independent.

For the final system, we have:

y = (-1/2)×x + 2

y = (-1/2)×x + 2

Answers

Answer:

Step-by-step explanation:

To determine if the graphs of two linear equations are parallel, we need to compare their slopes. If the slopes are equal, then the lines are parallel. If the slopes are not equal, then the lines are not parallel.

In case (a), the two equations are y = x + 3 and y = x + 6. Both equations have a slope of 1, which means the lines have the same steepness. However, the y-intercepts are different (3 and 6), which means the lines are shifted up or down relative to each other. Since the slopes are equal, but the y-intercepts are different, the lines are parallel.

In case (b), the two equations are y = 4x - 1 and y = 1 - 4x. Both equations have a slope of -4, which means the lines have the same steepness. However, the y-intercepts are different (-1 and 1), which means the lines are shifted up or down relative to each other. Since the slopes are equal, but the y-intercepts are different, the lines are not parallel.

In case (c), the two equations are y = 2x - 3 and y = -2x + 3. The slopes of the two equations are 2 and -2, which are negative reciprocals of each other. This means the lines are perpendicular, not parallel.

In case (d), the two equations are 3y = x - 12 and 6y = 2x + 12. We can rewrite these equations in slope-intercept form by solving for y. The first equation becomes y = (1/3)x - 4 and the second equation becomes y = (1/2)x + 2. The slopes of the two equations are 1/3 and 1/2, which are not equal. Therefore, the lines are not parallel.

Answer:

22. Parallel

23. Not parallel

24. Not parallel

25. Parallel

Step-by-step explanation:

The slope equation form of a line is

y = mx + b

where

m = slope

b = y-intercept

If two lines are parallel their slopes, the value of m will be the same, in slope-intercept form

Q22

y = x + 33 → slope = 1
y = x + 6 →  slope = 1

Slopes are the same with = 1
Hence  the lines are parallel

Q23
y = 2x - 3  →  slope m = 2
y = -2x + 3  →  slope m = -2
Slopes not equal hence not parallel

Q24
y = 4x - 1 →  slope = 4
y = 1 --4x or y = - 4x + 1  → slope = - 4  

Slopes are different, hence not parallel

Q25
3y = x - 12
6y = 2x + 12

Divide the first equation by 3
=> 3y/3 = x/3 - 12/3
=> y = x/3 -4    →   slope = 1/3

Divide the second equation by 6
6y/6 = 2x/6 + 12/6
y = x/3 + 2  →   slope = 1/3

Slopes are same, hence parallel

Answers

Answer:

To find the scale of the photograph, we need to determine the ratio between the actual height of the man and the height of the man in the photograph.

First, we convert the height of the man from feet to inches:

6 feet = 6 x 12 = 72 inches

Next, we can set up a proportion:

actual height of man / height of man in photograph = scale factor

Substituting the given values, we get:

72 inches / 1.5 inches = scale factor

Simplifying, we get:

scale factor = 48

Therefore, the scale of the photograph is 1:48, which means that one inch in the photograph represents 48 inches (or 4 feet) in real life.

For each table, state if the model is linear or exponential and write an equation.

Answers

Answers:

Linear; equation is   y = -5x+15Linear; equation is    y = -x+4Exponential;  equation is   y = 80*2^x

=====================================================

Explanation:

Problem 1

Each time x goes up by 1, y goes down by 5. This constant rate of change leads to the equation being linear. The slope is m = -5/1 = -5. You can use the slope formula for any two points in the table to confirm this is the correct slope.

The y intercept is b = 15 because we have x = 0 lead to y = 15.

Therefore, we go from y = mx+b to y = -5x+15

-----------------------------------

Problem 2

Each time x goes up by 3, the y coordinate goes down by 3. Therefore, we have another linear equation here. The slope is m = -3/3 = -1.

The y intercept is b = 4 because x = 0 leads to y = 4.

y = mx+b turns into y = -x+4

-----------------------------------

Problem 3

Each time x goes up by 1, y is NOT going up the same amount. The jump from 10 to 20 is +10. The jump from 20 to 40 is +20. And so on.

Therefore, this equation isn't linear. Instead it's exponential. Each y term doubles when x increases by 1, so that's why the b term is b = 2.

The initial term is a = 80 because x = 0 leads to y = 80.

We go from y = a*b^x to y = 80*2^x

-----------------------------------

You can use a tool like Desmos or GeoGebra to visually confirm each of the answers. Both also offer support for function tables.

Answer:

1.  y = -5x + 15.

2. y = -x + 4.

3. y = 80(2^(x/3))

Step-by-step explanation:

1.

From the given data, we can see that as x increases by 1, y decreases by a fixed amount of 5. This means that the relationship between x and y is linear, specifically a decreasing linear relationship.

To write the equation for a linear relationship, we need to find the slope (m) and y-intercept (b).

Using the formula for slope:

m = (change in y) / (change in x)

m = (0 - 30) / (3 - (-3))

m = -5

Using the point-slope form of a linear equation:

y - y1 = m(x - x1)

y - 30 = -5(x - (-3))

y - 30 = -5x - 15

y = -5x + 15

So the equation for this linear relationship is y = -5x + 15.

2.

From the given data, we can see that as x increases by 3, y decreases by a fixed amount of 3. This means that the relationship between x and y is linear, specifically a decreasing linear relationship.

To write the equation for a linear relationship, we need to find the slope (m) and y-intercept (b).

Using the formula for slope:

m = (change in y) / (change in x)

m = (-5 - 13) / (9 - (-9))

m = -18 / 18

m = -1

Using the point-slope form of a linear equation:

y - y1 = m(x - x1)

y - 13 = -1(x - (-9))

y - 13 = -1(x + 9)

y = -x + 4

So the equation for this linear relationship is y = -x + 4.

3.

From the given data, we can see that as x increases by 1, y doubles. This means that the relationship between x and y is exponential.

To write the equation for an exponential relationship, we can use the general form of an exponential function:

y = ab^x

where a is the initial value, b is the base, and x is the exponent.

To find a and b, we can use the first and fourth data points since they have the smallest and largest values of y, respectively.

When x = -3, y = 10, so we have:

10 = ab^(-3)

When x = 0, y = 80, so we have:

80 = ab^(0)

From the second equation, we can see that a = 80. Substituting this into the first equation, we get:

10 = 80b^(-3)

Simplifying, we get:

b = 2^(1/3)

So the equation for this exponential relationship is:

y = 80(2^(1/3))^x

Simplifying further:

y = 80(2^(x/3))

B. Find the interest earned.

Answers

The required final amount and interest are 3311.05 and 311.05

What is Compound interest?

When you make interest on both the money you've saved and the interest you've earned, this is known as compound interest.

According to question:

A. To find the amount of money in the account after 5 years, we can use the formula for compound interest:

[tex]$$A = P \left(1 + \frac{r}{n}\right)^{nt}$$[/tex]

where A is the final amount, P is the principal, r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the number of years.

In this case, P = $3000, r = 0.02 (2%), n = 4 (compounded quarterly), and t = 5. Plugging in these values, we get:

[tex]$$A = 3000\left(1 + \frac{0.02}{4}\right)^{4\cdot5} \approx $3311.05$$[/tex]

Therefore, there will be approximately 3311.05 in the account after 5 years.

B. To find the interest earned, we can subtract the principal from the final amount:

[tex]$$I = A - P = $3311.05 - $3000 = $311.05$$[/tex]

Therefore, the interest earned is 311.05.

The volume of a cylinder can be calculated using the following formula:

[tex] \Large{\sf V = B \times h} [/tex]

Where:

V is the volume of the cylinder.B is the area of its base.h is the height of the cylinder.

[tex] \\ [/tex]

Since we are not given the area of its base, which is a circle, we will have to calculate it applying the following formula:

[tex] \Large{\sf B = \pi \times r^2} [/tex]

Where:

B is the area of the circle (the base of the cylinder).r is its radius.

[tex] \\ [/tex]

Combining these two formulas, we can express the volume of the cylinder as follows:

[tex] \Large{\sf V = \underbrace{\sf \pi \times r^2}_{B} \times h} [/tex]

[tex] \\ [/tex]

Now, rearrange the formula to isolate the height, h.

[tex] \sf V = \pi \times r^2 \times h \Longleftrightarrow \dfrac{V}{\pi \times \times r^2} = \dfrac{ \pi \times r^2 \times h}{\pi \times r^2 } \Longleftrightarrow h = \dfrac{V}{\pi \times r^2} [/tex]

[tex] \\ [/tex]

Substitute these values into our formula:

[tex] \sf h = \dfrac{492,452.48 \: m^3}{(52 \: m)^2 \times 3.14 } = \dfrac{492,452.48 \: m^3}{8,490.56\: m^2 } \\ \\ \\ \\ \implies \boxed{\boxed{\sf h = 58 \: m}} [/tex]

If Ramiro stops using his credit card, how long will it take him (in months) to pay off the $500.00 if he makes only the minimum payment?

Answers

Answer:

Using the formula for the number of months to pay off a credit card balance with minimum payments:

Number of months = (-1/30) * log(1 - (balance * monthly rate / payment))

where balance is the initial balance, monthly rate is the APR divided by 12, and payment is the minimum payment.

Plugging in the given values, we get:

Number of months = (-1/30) * log(1 - (500 * 0.01824/12 / 10))

Number of months = 46.05

Rounding up to the nearest whole number, it will take Ramiro 47 months to pay off his credit card balance with only minimum payments.

Much of Ann's investments are in Cilla Shipping. Ten years ago, Ann bought seven bonds issued by Cilla Shipping, each with a par value of $500. The bonds had a market rate of 95.626. Ann also bought 125 shares of Cilla Shipping stock, which at the time sold for $28.00 per share. Today, Cilla Shipping bonds have a market rate of 106.384, and Cilla Shipping stock sells for $30.65 per share. Which of Ann's investments has increased in value more, and by how much?

Answers

Using basic arithmetic operation, Ann's stock investment has increased in value more, by $331.25, compared to her bond investment, which has increased in value by $378.66.

The current value of Ann's bond investment can be calculated using the following formula:

Current Value of Bonds = Par Value x Market Rate

Since Ann has 7 bonds with a par value of $500 each, the total par value of her bond investment is:

$500 x 7 = $3,500

Using the market rate of 106.384, we can calculate the current value of Ann's bond investment as:

Current Value of Bonds = $3,500 x 1.06384 = $3,725.44

The current value of Ann's stock investment can be calculated by multiplying the number of shares she owns by the current stock price:

Current Value of Stock = Number of Shares x Stock Price

Since Ann owns 125 shares of Cilla Shipping stock and the current stock price is $30.65, the current value of her stock investment is:

Current Value of Stock = 125 x $30.65 = $3,831.25

To determine which investment has increased in value more, we need to compare the difference between the current and original values of each investment. The original value of Ann's bond investment is:

Original Value of Bonds = Par Value x Market Rate = $500 x 7 x 0.95626 = $3,346.78

The difference between the current and original value of Ann's bond investment is:

$3,725.44 - $3,346.78 = $378.66

The original value of Ann's stock investment is:

Original Value of Stock = Number of Shares x Stock Price = 125 x $28.00 = $3,500

The difference between the current and original value of Ann's stock investment is:

$3,831.25 - $3,500 = $331.25

Hence, Ann's stock investment has increased in value more, by $331.25, compared to her bond investment, which has increased in value by $378.66.

What is the solution to the equation log2 (5x - 2) = -2?

Answers

Step-by-step explanation:

We can solve for x using the properties of logarithms as follows:

log2 (5x - 2) = -2

2^(-2) = 5x - 2 (using the definition of logarithms)

1/4 = 5x - 2 (simplifying 2^(-2))

5x = 2 + 1/4 = 9/4

x = 9/20

Therefore, the solution to the equation log2 (5x - 2) = -2 is x = 9/20.

Question 4
Both of them will have the same amount of money after
50/3 years
or
16 2/3 years
or
16 years 8 months

Step-by-step explanation:

Malik's interest rate as decimal = 2/100 = 0.02Saraiah's   interest rate as decimal = 1/100 = 0.01The formula for simple interest is given as
I = P r t\The total amount earned including interest
= Principal + Interest
= P + P · r · t
= P(1 + r · t)We are asked to use y for the total amount and x for the number of yearsIn terms of y = total amount and x = number of years:
y = P(1 + r · x)

#3

Amount in Malik's account after x years given 2% interest
y = 350(1 + 0.02x)
y = 350 + 7x


For Saraiah's account:
y = 400(1 + 0.01x)
y = 400 + 4x

#4

If both Malik and Saraiah have the same amount of money after x years, then the right side of both their equations must be equal

Therefore

[tex]350+7x = 400+4x\\\\\mathrm{Move}\:350\:\mathrm{to\:the\:right\:side \:by \:subtracting\: 350 \:from\:both\: sides}\\350+7x-350=400+4x-350\\\\\mathrm{Simplify}\\7x=4x+50\\\\[/tex]


[tex]\mathrm{Subtract\:}4x\mathrm{\:from\:both\:sides}\\\\7x-4x=4x+50-4x\\3x=50\\\\\mathrm{Divide\:both\:sides\:by\:}3\\\\\dfrac{3x}{3}=\dfrac{50}{3}\\\\x=\dfrac{50}{3}[/tex]

Therefore both of them will have the same amount of money after [tex]\dfrac{50}{3}[/tex] years which is [tex]{16\dfrac{2}{3}[/tex] years

The measure of angle x in the hexagon is 140 degree.

What is the measure of angle x?

The formula for calculating the sum of interior angles of a polygon is ( n − 2 ) × 180 degree.

where is the number of sides

Since the number of sides of the polygon in the diagram is 6, we can find the sum of the interior angle.

Sum of interior angle = ( n − 2 ) × 180

Plug in n = 6

Sum of interior angle = ( 6 − 2 ) × 180

Sum of interior angle = ( 4 ) × 180

Sum of interior angle = 720°

Next, we sum up the interior angles given in the diagram equate to 720 degree and solve for x.

108 + 155 + 123 + 104 + 90 + x = 720

Collect and add like terms

580 + x = 720

Subtract 580 from both sides

580 - 580 + x = 720 - 580

x = 720 - 580

x = 140°

Therefore, the value of x is 140 degree.

Answers

The mean and standard deviation for Brett Favre's per game pass completions were 21.4 and 6.47, respectively, and all measurements fall within two standard deviations of the mean.

What is standard deviation ?

Standard deviation is a measure of the amount of variation or dispersion in a set of data. It is a statistic that indicates how much the individual data points deviate from the mean or average of the dataset.

a. Here's a stem-and-leaf plot for the number of passes completed by Brett Favre for each of the 16 regular season games in the fall of 2006:

     

Each stem represents the tens digit of the number of passes completed, and each leaf represents the ones digit.

b. To calculate the mean and standard deviation for Brett Favre's per game pass completions, we can use the following formulas:

mean = (sum of all values) / (number of values)

standard deviation = sqrt[(sum of (each value minus the mean) squared) / (number of values - 1)]

Using these formulas, we get:

mean = (15 + 31 + 25 + 22 + 22 + 19 + 17 + 28 + 24 + 5 + 22 + 24 + 22 + 20 + 26 + 21) / 16 = 21.4

standard deviation = [tex]sqrt[((15-21.4)^2 + (31-21.4)^2 + (25-21.4)^2 + (22-21.4)^2 + (22-21.4)^2 + (19-21.4)^2 + (17-21.4)^2 + (28-21.4)^2 + (24-21.4)^2 + (5-21.4)^2 + (22-21.4)^2 + (24-21.4)^2 + (22-21.4)^2 + (20-21.4)^2 + (26-21.4)^2 + (21-21.4)^2) / (16-1)] = 6.47 \\ \\= 6.47[/tex] (rounded to two decimal places)

Therefore, Brett Favre's per game pass completions had a mean of 21.4 and a standard deviation of 6.47.

c. To find the proportion of the measurements that lie within two standard deviations of the mean, we need to find the range of values that fall within two standard deviations above and below the mean. We can use the following formula:

range = mean ± (2 × standard deviation)

Plugging in the values we calculated in part b, we get:

range = 21.4 ± (2 × 6.47) = 8.46 to 34.34

Therefore, the mean and standard deviation for Brett Favre's per game pass completions were 21.4 and 6.47, respectively, and all measurements fall within two standard deviations of the mean.

Please help me, this question is so confusing and I tried almost every way to solve this and it’s still wrong. It wants me to find how much metal need to make the 16 cans and I tried multiplying 16 and it’s still wrong. Please help! Diameter is 8, height is 9. Please use 3 as pi to solve.

Answers

Answer:

[tex]4992 \text{ cm}^2[/tex]

Step-by-step explanation:

We can model the amount of metal, in square centimeters, that is needed to make a soup can with the expression:

[tex](2 \cdot \text{area of base}) + (\text{area of side})[/tex]

We can first solve for the surface area of a soup can, using the fact that its bases are circles.

[tex]A_{\text{circle}} = \pi r^2[/tex]

↓ substituting 3 for π

[tex]A_{\text{base}} = 3r^2[/tex]

↓ plugging in radius (which is 1/2 of diameter, given as 8)

[tex]A_{\text{base}} = 3(4)^2[/tex]

↓ simplifying

[tex]A_{\text{base}} = 48 \text{ cm}^2[/tex]

Then, we can solve for the area of its side, which we can think of as an elongated circumference (circumference multiplied by height).

[tex]A_{\text{circumference}} = \pi d[/tex]

[tex]A_{\text{side}} = h(\pi d)[/tex]

↓ substituting 3 for π

[tex]A_{\text{side}} = h(3d)[/tex]

↓ plugging in height and diameter

[tex]A_{\text{side}} = 9(3 \cdot 8)[/tex]

↓ simplifying

[tex]A_{\text{side}} = 216 \text{ cm}^2[/tex]

Next, we can solve for the surface area of one soup can.

[tex](2 \cdot \text{area of base}) + (\text{area of side})[/tex]

↓ plugging in solved values

[tex](2 \cdot 48 \text{ cm}^2) + 216 \text{ cm}^2[/tex]

↓ simplifying

[tex]96 \text{ cm}^2 + 216 \text{ cm}^2[/tex]

↓ performing addition

[tex]312 \text{ cm}^2[/tex]

Finally, we can solve for the amount of metal needed for 16 cans by multiplying the amount for 1 can by 16.

[tex]16 \cdot 312 \text{ cm}^2[/tex]

↓ performing multiplication

[tex]\boxed{4992 \text{ cm}^2}[/tex]
