The following sets of numbers could represent the three sides of a

triangle is {7, 15, 20}.

The set of numbers {7, 15, 20} could represent the three sides of a triangle, but the other sets of numbers do not satisfy the triangle inequality theorem, which states that the sum of any two sides of a triangle must be greater than the third side. Checking the sets of numbers:

For {7, 15, 20}, 7 + 15 > 20, 7 + 20 > 15, and 15 + 20 > 7, so they satisfy the triangle inequality theorem and could represent the sides of a triangle.

For {7, 16, 23}, 7 + 16 < 23, so they do not satisfy the triangle inequality theorem and cannot represent the sides of a triangle.

For {11, 22, 35}, 11 + 22 < 35, so they do not satisfy the triangle inequality theorem and cannot represent the sides of a triangle.

For {5, 17, 22}, 5 + 17 < 22, so they do not satisfy the triangle inequality theorem and cannot represent the sides of a triangle.

Therefore, the answer is {7, 15, 20}.

Answer:

the equation of line BC is y = (-7/5)x + (48/5).

Step-by-step explanation:

To find the equation of the line that passes through points B and C, we first need to determine the coordinates of point C. Since the angle at B is a right angle, we can use the slope of line AB to find the slope of line BC.

The slope of line AB is:

mAB = (yB - yA) / (xB - xA)

= (4 - (-1)) / (4 - (-3))

= 5/7

Since lines AB and BC are perpendicular, the slope of line BC is the negative reciprocal of the slope of line AB:

mBC = -1 / mAB

= -7/5

Now we can use the point-slope form of the equation of a line to find the equation of line BC. We can use point B as the known point, since we already know its coordinates:

y - yB = mBC(x - xB)

Substituting the values we have:

y - 4 = (-7/5)(x - 4)

Expanding and simplifying:

y - 4 = (-7/5)x + (28/5)

y = (-7/5)x + (48/5)

The mode for the region A is 2.6.

What exactly is mode?

In statistics, the mode is the value that has highest frequency in a data set. It is one of the three measures of central tendency, along with the mean and median.

To find the mode of a data set, you simply identify the value that appears most often. If no value is repeated, the data set has no mode.

The mode is particularly useful when dealing with categorical data or data that can be easily grouped into categories, such as colors, types of fruit, or letter grades. In such cases, the mode can provide insight into which category is most common or prevalent.

Now,

As given Values for Region A are

2.3  2.5  2.6  2.6  2.6  2.7  2.7  2.8

Answer:

6 weeks and 840 hours

Step-by-step explanation:

There are 168 hours in one week.

24 hrs/day * 7 days = 168 hours

1008 hours ÷ 24 hours(1 day) = 42 days ÷ 7 days in a week = 6 weeks

168 hours/week * 5 weeks = 840 hours

Answer:

First, we need to find the length and width of the rectangle. The length is the distance between the points (11, 5) and (-6, 5), which is 11 - (-6) = 17 feet. The width is the distance between the points (11, 5) and (11, -2), which is 5 - (-2) = 7 feet.

The area of the rectangle is the product of the length and width, so A = 17 * 7 = 119 square feet.

Therefore, the answer is 119 ft2.

Answer: a) The profit function can be written as:

P(x) = 5x - 400x + 600

To find the asymptotes, we can look at the denominator of the second term, which is (x - 3). This means that there is a vertical asymptote at x = 3. To find the intercepts, we can set P(x) = 0:

5x - 400x + 600 = 0

Solving for x, we get:

x = 1.5 and x = 2.5

Therefore, there are x-intercepts at (1.5, 0) and (2.5, 0). To sketch the graph, we can also note that the coefficient of x^2 is negative, which means that the graph is a downward-facing parabola.

b) The domain of the function is the set of all possible values of x, which in this context represents the amount of coffee sold. Since we cannot sell a negative amount of coffee, the domain is x ≥ 0.

The range of the function is the set of all possible values of P(x), which represents the profit. Since the coefficient of x^2 is negative, the maximum profit occurs at the vertex of the parabola. The vertex has x-coordinate:

x = -b/(2a) = -(-400)/(2(-200)) = 1

Therefore, the maximum profit occurs when x = 1. The vertex has y-coordinate:

P(1) = 5(1) - 400(1) + 600 = 205

Since the coefficient of x^2 is negative, the range is (-∞, 205].

c) The horizontal asymptote of the function is y = -400, which represents the long-term average profit per kilogram of coffee sold. This means that as x gets very large, the profit per kilogram approaches -400. This could happen, for example, if the cost of producing the coffee increased significantly while the price remained the same.

d) To find the amount of coffee that must be sold to make a profit of $4000, we can set P(x) = 4000 and solve for x:

5x - 400x + 600 = 4000

Simplifying, we get:

-395x = -3400

Dividing both sides by -395, we get:

x ≈ 8.61

Therefore, approximately 8.61 kg of coffee must be sold to make a profit of $4000.

Step-by-step explanation:

There is not enough evidence to support the analyst's claim that the stocks lost value from one hour to the next on that business day.

The null hypothesis is that there is no significant difference between the two sets of prices, while the alternative hypothesis is that there is a significant difference.

Using a t-test calculator, we can find the t-value and p-value:

t-value = -0.322

p-value = 0.757

At a significance level of 0.01, the critical t-value with 6 degrees of freedom is ±3.707. Since the calculated t-value of -0.322 is within this range, we fail to reject the null hypothesis.

Therefore, there is not enough evidence to support the analyst's claim that the stocks lost value from one hour to the next on that business day.

Answer:

7.14 years

Step-by-step explanation:

We can use the formula for simple interest to solve this problem:

Simple Interest = Principal x Rate x Time

where the principal is the initial investment, the rate is the annual interest rate, and the time is the number of years.

We know that Geneva wants to save $12,000, and she already has $8,000 from her bonus, so she needs to earn an additional $4,000 in interest. We can use this amount as the principal in the formula.

Simple Interest = $4,000

Principal = $8,000

Rate = 0.07 (7% expressed as a decimal)

Plugging in the values, we get:

$4,000 = $8,000 x 0.07 x Time

Simplifying, we get:

Time = $4,000 / ($8,000 x 0.07)

Time = 7.14 years (rounded to the nearest hundredth)

Therefore, Geneva will need to leave her money in the account for approximately 7.14 years to accumulate the $12,000 she needs

Formula = Number x 100/Percent = 600 x 100/3 = 2,000

Following shows the steps on how to derive this formula and find out 3% of what number is 60.

Step 1: If 3% of a number is 60, then what is 100% of that number? Setup the equation.

60/3% = Y/100%

Measure of the arc or angle indicated is 150.9 degrees.

In geometry, an arc is a portion of the circumference of a circle or any other curved shape. It is defined by two endpoints and all the points on the curve that lie between them. An arc is usually named by its two endpoints, with a small arc symbol above them to indicate that it is an arc.

The length of an arc can be calculated using the formula:

Arc length = (central angle/360) x 2πr

where r is the radius of the circle, and the central angle is the angle subtended by the arc at the center of the circle, measured in degrees.

The measure of an arc is the degree measure of the central angle subtended by the arc. A semicircle is an arc that subtends a central angle of 180 degrees, and a full circle is an arc that subtends a central angle of 360 degrees.

Since DE and PE are chords of the circle, and they intersect at point P, we can use the intersecting chords theorem to find the length of DP. Let x be the length of DP. Then:

DP * PE = DE * PC

x * (x + PE) = ([tex]\frac{CE}{2}[/tex]) * ([tex]\frac{CE}{2}[/tex])

x² + x(PE) - [tex]\frac{CE}{2}^{\frac{2}{4} }[/tex] = 0

Since angle DPE is 60 degrees, we can use the law of cosines to find PE. Let y be the length of PE. Then:

y² = DE² + DP² - 2 * DE * DP * cos(60)

y² = ([tex]\frac{CE}{2}[/tex])² + x^2 - ([tex]\frac{CE}{2}[/tex]) * x

Substitute this expression for y^2 into the equation for x and simplify:

[tex]x^{2} +x((\frac{CE}{2})^{2} + x^{2} -\frac{CE}{2} *x)^{0.5} -(\frac{CE}{2} ^{\frac{2}{4} } )=0[/tex]

Solve for x:

x = [tex]\frac{CE^{2} -4*(CE^{2} -3*\frac{CE}{2} ^{2} )^{0.5} }{4}[/tex]

x = [tex]\frac{3}{4} *\frac{CE^{2} }{CE^{2} -12}[/tex]

Now we can find the measure of the CD arc by using the formula for the central angle:

CD arc = [tex]2*arctan(\frac{DP}{CE})[/tex]

CD arc = [tex]2*arctan(\frac{x}{\frac{CE}{2} } )[/tex]

CD arc = [tex]2* arctan(CE^{2} -4*(CE^{2} -3*\frac{(\frac{CE}{2} ^{2})^{0.5}}{CE^{2}-12 } ))[/tex]

Simplifying this expression, we get:

[tex]CD arc=2*arctan(2*3^{\frac{1}{2} } -1)[/tex]

CD arc ≈ 150.9 degrees.

Measure of the arc or angle indicated in the given figure is 150.9 degrees.

In geometry, an arc is a portion of the circumference of a circle or other curved shape. It is defined by his two endpoints and all midpoints of the curve. Arcs are usually named after their two endpoints, with a small arc symbol above them to indicate that they are arcs.

Arc Length = (Center Angle/360) x 2πr

where r is the radius of the circle and the central angle is the angle the arc makes at the center of the circle, measured in degrees.

The arc measurement is the angle of the central angle defined by the arc. A half circle is an arc that spans a central angle of 180 degrees, and a full circle is an arc that spans a central angle of 360 degrees.

Since DE and PE are chords of the circle and intersect at P, we can use the chord rule to find the length of DP. Let x be the length of DP.  Then:

DP × PE = DE × PC

x × (x + PE) = (CE/2) × (CE/2)

x² + x(PE) - [tex]\frac{CE}{2} ^{\frac{2}{4} }[/tex] = 0

Since angle DPE is 60 degrees, we can use the law of cosines to find PE. Let y be the length of PE. Then:

y² = DE² + DP² - 2 × DE × DP × cos(60)

y² = ([tex]\frac{CE}{2}[/tex])² + x² -  ([tex]\frac{CE}{2}[/tex]) × x

Substitute this expression for y² into the equation for x and simplify:

[tex]x^{2} +x((\frac{CE}{2} ^{2}) + x^{2} - \frac{CE}{2}*x)^{0.5} -[/tex] [tex]\frac{CE}{2} ^{\frac{2}{4} }[/tex] = 0

Solve for x:

x = [tex]\frac{CE^{2} - 4*(CE^{2}-3*\frac{CE}{2} ^{2})^{0.5} }{4}[/tex]

x = (3/4) × (CE²/CE²-12)

Now we can find the measure of the CD arc by using the formula for the central angle:

CD arc = 2arc tan(DP/CE)

CD arc = 2arc tan [x/(CE/2)]

CD arc = 2arc tan (CE² - 4 × (CE² - 3 × [tex]\frac{(\frac{CE}{2} ^{2}) ^{0.5} }{CE^{2}-12 }[/tex] )

(a) the value of the investment after 5 years is $14,917.95, after 10 years is $23,673.58, and after 15 years is $37,337.35,

b) the amount of the final payment is $688.32.

What is compound interest?

Compound interest is when you earn interest on both the money you've saved and the interest you earn.

We can use the formula for compound interest to solve this problem:

[tex]A = P(1 + r/n)^{(nt)}[/tex]

where A is the final amount, P is the principal (initial investment), 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 time (in years).

(a) For 5 years with semiannual compounding:

n = 2 (compounded semiannually)

r = 0.08 (8% annual rate)

t = 5

[tex]A = 9900(1 + 0.08/2)^{(2*5)}[/tex]

A = $14,917.95

(b) For 10 years with semiannual compounding:

n = 2 (compounded semiannually)

r = 0.08 (8% annual rate)

t = 10

[tex]A = 9900(1 + 0.08/2)^{(2*10)}[/tex]

A = $23,673.58

(c) For 15 years with semiannual compounding:

n = 2 (compounded semiannually)

r = 0.08 (8% annual rate)

t = 15

[tex]A = 9900(1 + 0.08/2)^{(2*15)}[/tex]

A = $37,337.35

Therefore, the value of the investment after 5 years is $14,917.95, after 10 years is $23,673.58, and after 15 years is $37,337.35, assuming the interest is compounded semiannually.

To calculate the final payment, we can first find the balance of the loan at the end of the fifth year, and then use this as the principal to calculate the balance at the end of the tenth year.

The interest rate is 5% per year, compounded quarterly. This means that the quarterly interest rate is:

r = 5% / 4 = 0.0125

Let B be the balance of the loan after 5 years. Then we have:

B = 1000*(1 + r)²⁰- 200*(1 + r)⁴

where the first term is the future value of the initial loan after 5 years, and the second term is the present value of the first payment of $200.

Plugging in the values, we get:

B = 1000*(1 + 0.0125)²⁰ - 200*(1 + 0.0125)⁴

B = 1000*(1.0125)²⁰ - 200*(1.0125)⁴

B = 1346.49

So the balance of the loan after 5 years is $1346.49. We can use this as the principal to calculate the balance at the end of the tenth year, which is the final payment we are looking for.

Let P be the final payment. Then we have:

P = 1346.49*(1 + r)⁴⁰ - 800*(1 + r)²⁰

where the first term is the future value of the balance after 10 years, and the second term is the present value of the second payment of $800.

Plugging in the values, we get:

P = 1346.49*(1 + 0.0125)⁴⁰ - 800*(1 + 0.0125)²⁰

P = 1346.49*(1.0125)⁴⁰ - 800*(1.0125)²⁰

P = 688.32

So the amount of the final payment is $688.32.

hence, the answers to both questions are as:

(a) the value of the investment after 5 years is $14,917.95, after 10 years is $23,673.58, and after 15 years is $37,337.35,

b) the amount of the final payment is $688.32.
