Solve for x.

one seventh times the absolute value of the quantity x minus 3 end quantity minus 2 equals 9

x = 74 and x = 80
x = −46 and x = 52
x = −52 and x = 46
x = −74 and x = 80

Answers

The solutions to the given absolute value equation are:

x = −74 and x = 80

How to solve the given equation for x?

Here we want to solve the absolute value equation:

(1/7)*|x - 3| - 2 = 9

To solve this, we first need to isolate the absolute value part, so we get:

(1/7)*|x - 3| - 2 = 9

(1/7)*|x - 3| = 9 + 2

(1/7)*|x - 3| = 11

|x - 3| = 11*7

|x - 3| = 77

Now we can decompose the absolute value equation into two simpler ones, which are:

x - 3 = 77

x - 3 = -77

Solving those two equations we get:

x = 77 + 3 = 80

x = -77 + 3 = -74

Thus the solutions are:

x = -74 and x = 80, we conclude that the correct option is the last one.

evaluate the following expression 2.5 x 10^4 - 1.5 ×10^3

Answers

You have the following expression:

2.5 x 10⁴ - 1.5 x 10³

in order to simplify the previous expression, consider that the factors with base 10 have to have the same exponent. You can write the second term as a factor with 10⁴ if you write 1.5 as 0.15 (if you increase the exponent you move the decimal point to the left). Then, you can subtract the coefficients of the term and put the same factor x 10⁴:

Then, you have:

1.5 x 10³ = 0.15 x 10⁴

2.5 x 10⁴ - 0.15 x 10⁴ = 2.35 x 10⁴

A trader owns 852 shares of a stock and plans on selling covered calls using standard contracts on half of her shares. how many contracts could she sell?

Answers

The trader could sell 4 covered call contracts on half of her shares, covering a total of 400 shares (4 contracts * 100 shares per contract), leaving her with 452 shares remaining uncovered.

To determine the number of covered call contracts a trader could sell when owning 852 shares of a stock and planning to cover half of her shares, we need to consider that each standard covered call contract typically covers 100 shares of the underlying stock.

Since the trader plans to sell covered calls on half of her shares, we can calculate the number of shares she wants to cover as 852/2 = 426 shares.

To determine the number of covered call contracts, we divide the number of shares to be covered by the number of shares covered per contract:

Number of contracts = Number of shares to be covered / Number of shares covered per contract

                  = 426 shares / 100 shares per contract

                  = 4.26 contracts.

Since contracts are usually traded in whole numbers, the trader could sell 4 covered call contracts. However, it's important to note that fractional contracts are generally not available, so in practical terms, the trader would likely round down to the nearest whole number.

circuit optimation problem georgina orwell wants to build a rectangular pig pen along the side of a pre-existing barn, so she will only need fencing on three sides. she has 200 feet of fencing and will use all of it to maximize the pig pen. find the maximum area (in square feet) she can enclose.

Answers

The maximum area that Georgina Orwell can enclose is 10000 square feet.

The maximum area that Georgina Orwell can enclose with 200 feet of fencing is:

Let x be the length of the side of the pig pen along the barn and y be the width of the pig pen.

We know that:

x + 2y = 200

We can use this equation to find the value of one variable in terms of the other. For example, we can solve for y:

y = (200 - x) / 2

We can use this equation to find the area of the pig pen:

A = xy = x((200 - x) / 2)

= (200x - x^2) / 2

To find the maximum area, we need to find the value of x that maximizes A. To do this, we can take the derivative of A with respect to x and set it equal to zero:

A'(x) = (200 - 2x) / 2 = 0

200 - 2x = 0

x = 100

So the maximum area is:

A = (200x - x^2) / 2 = (200 * 100 - 100^2) / 2 = 10000 sq ft.

Therefore, the maximum area that Georgina Orwell can enclose is 10000 square feet.

A parabola opening up or down has vertex (–7,1) and passes through 10 309/20. Write its equation in vertex form. Simplify any fractions

Answers

The equation of the parabola in vertex form is y = (1/20)(x + 7)^2 + 1.

To write the equation of a parabola in vertex form, we use the equation:

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

where (h, k) represents the vertex of the parabola.

Given that the vertex is (-7, 1), we have h = -7 and k = 1. Substituting these values into the equation, we get:

y = a(x + 7)^2 + 1

Now, we need to find the value of 'a' to complete the equation. Since the parabola passes through the point (10, 309/20), we can substitute these coordinates into the equation:

309/20 = a(10 + 7)^2 + 1

309/20 = a(17)^2 + 1

309/20 = a(289) + 1

309/20 = 289a + 1

To simplify the fraction, we multiply both sides by 20:

309 = 20(289a + 1)

309 = 5780a + 20

Now, we solve for 'a':

5780a = 309 - 20

5780a = 289

a = 289/5780

a = 1/20

Substituting this value of 'a' back into the equation, we have:

y = (1/20)(x + 7)^2 + 1

paid $3,945.90, including a commission of $113.40. Comerica
pays annual dividends of $1.92.
a. What was the cost per share?
b. What is the annual yield?

Answers

The Annual yield is approximately 2.92%.

To determine the cost per share and the annual yield, we need to perform some calculations based on the given information.

a. Cost per share:

The cost per share can be calculated by dividing the total cost (including the commission) by the number of shares.

Total cost = Cost of shares + Commission

Total cost = $3,945.90

Number of shares = 60

Cost per share = Total cost / Number of shares

Cost per share = $3,945.90 / 60

Cost per share ≈ $65.76

Therefore, the cost per share is approximately $65.76.

b. Annual yield:

The annual yield is the dividend per share divided by the cost per share, expressed as a percentage.

Dividend per share = $1.92

Annual yield = (Dividend per share / Cost per share) * 100

Annual yield = ($1.92 / $65.76) * 100

Annual yield ≈ 2.92%

Therefore, the annual yield is approximately 2.92%.

In summary:

a. The cost per share for Comerica Inc. is approximately $65.76.

b. The annual yield for Comerica Inc. is approximately 2.92%.

Ms.Lee bought some Reese and a bag of chips. They cost $4.36 altogether. The chips cost $1.60 more than the Reese. How much did the Reese cost?

Answers

Answer: $1.38

When distribution is shown as a symmetrical bell-shaped curve, what can be concluded about the data?
a. The mean, median, and mode are equal.
b. The mean is less than the median and mode.
c. The data shows moderate uniformity.
d. The mean is greater than the median and mode.

Answers

When a distribution is shown as a symmetrical bell-shaped curve then the mean, median, and mode are equal i.e., option (a) is correct.

A symmetrical bell-shaped curve, also known as a normal distribution or Gaussian distribution, is characterized by its symmetry around the mean.

In this type of distribution, the mean, median, and mode all coincide at the center of the curve.

This means that the central tendency measures, such as the mean (average), median (middle value), and mode (most frequent value), are all equal.

Option (a) states that the mean, median, and mode are equal, which aligns with the properties of a symmetrical bell-shaped curve. This equality occurs because the data is evenly distributed on both sides of the mean, resulting in a balanced distribution.

Options (b) and (d) suggest that the mean is either less than or greater than the median and mode, which does not hold true for a symmetrical distribution.

In a symmetrical distribution, the mean is located at the center of the data, and the median and mode share the same value as the mean.

Option (c) mentions moderate uniformity, but a symmetrical bell-shaped curve does not specifically indicate uniformity. Uniformity refers to a distribution where all data points have equal probability, resulting in a flat line.

In contrast, a symmetrical bell-shaped curve indicates a normal distribution with the majority of data concentrated around the mean, gradually decreasing towards the tails.

Therefore, based on the given options, option (a) is the correct conclusion when the distribution is shown as a symmetrical bell-shaped curve.

In February, Dawn's monthly allowance and Evelyn's monthly allowance were in the ratio 5: 8. In March, Mother increased Dawn's monthly allowance by 20% and decreased Evelyn's monthly allowance. Dawn and Evelyn then had the same amount of allowance. What was the percentage decrease in Evelyn's allowance in March?​

Answers

Answer:

25%

Step-by-step explanation:

Let Dawn’s monthly allowance be 5x. Let Evelyn’s monthly allowance then be 8x.

Percentage increase by 20% is the same as multiplying a number by 1.2

To find the percentage decrease of Evelyn’s monthly allowance, we can equate their allowances after the change of their initial allowance.

1.2 * 5x = k/100 * 8x

k represents the percentage

6x = 8xk/100

Cancel the x’s from both sides

6 = 8k/100

600 = 8k

k = 75

Therefore since 75% of Evelyn’s monthly allowance is equal to Dawn’s increased monthly allowance, this means Evelyn’s monthly allowance was decreased by 25%.

Answers

The triple iterated integral to evaluate is ∫∫∫r cos(e) dr de dz over the region 0.

To evaluate the triple iterated integral, we start by considering the limits of integration for each variable. In this case, the region of integration is given as 0, so the limits for all three variables are 0.

The triple iterated integral can be written as:

∫∫∫r cos(e) dr de dz

Since the limits for all variables are 0, the integral simplifies to:

∫∫∫0 cos(e) dr de dz

The integrand is cos(e), which is a constant with respect to the variable r. Therefore, integrating cos(e) with respect to r gives:

∫ cos(e) dr = r cos(e) + C1

Next, we integrate r cos(e) + C1 with respect to e:

∫(r cos(e) + C1) de = r sin(e) + C1e + C2

Finally, we integrate r sin(e) + C1e + C2 with respect to z:

∫(r sin(e) + C1e + C2) dz = r sin(e)z + C1ez + C2z + C3

Since the limits for all variables are 0, the result of the triple iterated integral is:

∫∫∫r cos(e) dr de dz = 0

Therefore, the value of the triple iterated integral is zero.
