When data consist of rates of change, such as speeds, the harmonic mean is an appropriate measure of central tendency. The harmonic mean for n data values, assuming no data value is 0, is given by the equation below. Suppose you drive 53 miles per hour for 100 miles, then 67 miles per hour for 100 miles. Use the harmonic mean to find your average speed. (Round your answer to two decimal places.)

Answers
Answer:
The measure of <CDO and <DCo are 60° and 30°.
Step-by-step explanation:
∠CDO = 1/2 ∠CDA
= 1/2 (120)° = 60°
∠ADC + ∠DCB = 180°
120° + ∠DCB = 180°
⇒ ∠DCB = 180° – 120° = 60°
∠DCO = 1/2 ∠DCB
= 1/2 (60°) = 30°
I hope this helps, have a good day! :D
So,
∠CDO = 1/2 ∠CDA
= 1/2 (120)° = 60°
∠ADC + ∠DCB = 180°
120° + ∠DCB = 180°
⇒ ∠DCB = 180° – 120° = 60°
∠DCO = 1/2 ∠DCB
= 1/2 (60°) = 30°

Answers
Answer:
C, D
Step-by-step explanation:
We can solve this graphically and analytically.
Graphically, looking at the attached image below, if we graph the two inequalities and plot the points, you can find the points which are solutions by finding the points in the overlapping area.
This obviously excludes A as it only appears in \(y \geq x+2\)
C is included as y \(\geq x+2\) includes the point on the line.
D is obviously a solution.
B is however not a solution because is lies on the line \(y = \frac{-5x}{2} - 3\), which the inequality excludes.
Analytically, if we can find one of the two inequalities where it is not a solution, it is not a solution of the system.
A: (0, 0)
\(y \geq x+2\\0 \geq 0 + 2\\0 \geq 2\\false\)
A is not a solution
B: (-2, 2)
\(y \geq x+2\\2 \geq -2 + 2\\2\geq 0\\true\)
\(y > \frac{-5x}{2} -3\\2 > \frac{-5(-2)}{2} - 3\\2 > 5 - 3\\2 > 2\\false\)
B is not a solution
C: (0, 2)
\(y \geq x+2\\2 \geq 0 + 2\\2 \geq 2\\true\\\\y>\frac{-5x}{2}-3\\2 > -3\\true\)
C is a solution
D:
\(y \geq x + 2\\6 \geq -1 + 2\\6 \geq 1\\true\\\\y > \frac{-5x}{2} - 3\\6 > \frac{-5(-1)}{2} - 3\\6 > \frac{5}{2} - \frac{6}{2}\\6 > \frac{-1}{2}\\true\)

Fill in the missing values below one at a time to find the quotient when x^3 - x^2 - 3x + 2 is divided by x - 2.
Answers
Therefore, the quotient when x³ - x² - 3x + 2 is divided by x - 2 is x² - 2x - 5 with a remainder of -3.
To find the quotient when x³ - x² - 3x + 2 is divided by x - 2, we will use the long division method. Here is the solution:
Step 1: The first term of the quotient is x². Multiply x² by x - 2 to get x³ - 2x². Subtract this product from x³ - x² to get: x² - 3x² = -2x²
Step 2: Bring down the next term of the dividend, which is -3x. The new dividend is -2x² - 3x.
Step 3: The second term of the quotient is -2x. Multiply -2x by x - 2 to get -2x² + 4x. Subtract this product from -2x² - 3x to get -5x.
Step 4: Bring down the last term of the dividend, which is +2. The new dividend is -5x + 2. Step 5: The third term of the quotient is -5. Multiply -5 by x - 2 to get -5x + 10. Subtract this product from -5x + 2 to get -3.

The value of a car will “depreciate” over time. For example, a car that was worth $24 000 when it was new, is being sold for $13 500 three years later. Determine the annual depreciation rate on this car. Express your final answer as a percent, rounded to one decimal place.
Answers
Answer:
The car will depreciate at a rate of 21.14% per year.
Step-by-step explanation:
Given that the value of a car will “depreciate” over time, and, for example, a car that was worth $ 24,000 when it was new, is being sold for $ 13,500 three years later, to determine the annual depreciation rate on this car the following calculation must be performed:
13,500 x (1 + X) ^ 1x3 = 24,000
13,500 x (1 + 0.2114) ^ 3 = 24,000
X = 21.14%
Therefore, the car will depreciate at a rate of 21.14% per year.

This diagram shows the blue prints a contractor drew for a ramp. In order for the ramp to meet safety regulations, the angle created by the bottom of the ramp and the ground should be no more than 18°.
How many degrees should the contractor lower the ramp by in order to meet safety regulations?
Enter your answer, rounded to the nearest tenth, in the box.
Answers
The contractor should lower the ramp by approximately 4.62° to meet safety regulations.
We have,
To determine the angle created by the bottom of the ramp and the ground, we can use the trigonometric function of sine.
In the given triangle, the height is 6 ft and the base is 16 ft.
The angle we want to find is opposite the height (let's call it θ).
The sine of an angle is defined as the ratio of the opposite side to the hypotenuse.
sin(θ) = opposite/hypotenuse
sin(θ) = 6/16
sin(θ) = 0.375
To find the angle θ, we can take the inverse sine (also known as arcsine) of 0.375:
θ = arcsin(0.375)
θ ≈ 22.62°
To meet safety regulations, the angle should be no more than 18°. Therefore, the contractor needs to lower the ramp by:
22.62° - 18° ≈ 4.62°
Thus,
The contractor should lower the ramp by approximately 4.62° to meet safety regulations.

People use water to cook, clean, and drink every day. An estimate of 22.7% of the water used each day is for cooking. If a family uses 68.1 gallons of water a day for cooking, how many gallons do they use every day?
Answers
We know that 22.7% of this amount is used for cooking,the family uses 300.001 gallons of water every day.
What is gallons?
Gallon is a unit of measurement used to quantify liquid volume in both the US customary and British imperial systems of measurement.
Let's start by using algebra to solve the problem.
Let x be the total amount of water the family uses every day. We know that 22.7% of this amount is used for cooking, which means:
0.227x = 68.1
To solve for x, we can divide both sides of the equation by 0.227:
x = 68.1 ÷ 0.227
x = 300.001 (rounded to three decimal places)
Therefore, the family uses 300.001 gallons of water every day.

Answers
The probability of her getting a red marble is the number of red marbles divided by the number of total marbles. Since she picked a green marble first, we must subtract one marble from the total number of marbles, so that the total # of marbles is 6 + 6 + 4 = 16 - 1 (green marble) = 15. Since there are 6 red marbles, our probability is 6/15 or 2/5. Converted to percentage form, this is 0.4 —> 40%

Write the equation of the line, in slope intercept form, that is perpendicular to 3x+6y=18 passing through the point (-4,2). Show your work.
Answers
Answer:
y = 2x + 10
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
3x + 6y = 18 ( subtract 3x from both sides )
6y = - 3x + 18 ( divide terms by 6 )
y = - \(\frac{1}{2}\) x + 3 ← in slope- intercept form
with slope m = - \(\frac{1}{2}\)
given a line with slope m then the slope of a line perpendicular to it is
\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{-\frac{1}{2} }\) = 2 , then
y = 2x + c ← is the partial equation
to find c substitute (- 4, 2 ) into the partial equation
2 = - 8 + c ⇒ c = 2 + 8 = 10
y = 2x + 10 ← equation of perpendicular line
