The following is the value of x and mBD: x = 83/6 and mBD⌢ = 83°.
Given circle E (⊙E) with diameter AC, we have the following information:
1. m∠CED = (3x)°
2. m∠BEC = (3x + 2)°
3. m∠AEB = (6x + 7)°
Since AC is the diameter of the circle, the inscribed angle ∠AEB is subtended by the diameter and thus forms a semicircle. In a semicircle, the inscribed angle is always a right angle. Therefore, m∠AEB = 90°. We can now set up the equation:
(6x + 7)° = 90°
Solving for x:
6x = 83
x = 83/6
Now, we need to find the measure of arc BD (mBD⌢). We can do this by finding the measure of angle BEC, as the measure of an inscribed angle is half the measure of its intercepted arc.
m∠BEC = (3x + 2)° = (3(83/6) + 2)° = (83/2)°
Since the measure of an inscribed angle is half the measure of its intercepted arc:
mBD⌢ = 2(m∠BEC) = 2(83/2)° = 83°
So, x = 83/6 and mBD⌢ = 83°.

The exterior angle of a triangle is 115° one of the interior opposite angle is 55°. The other interior angle is ?
Answer:
60°
Step-by-step explanation:
The exterior angle of a triangle is 115° one of the interior opposite angle is 55°. The other interior angle is ?
An exterior angle = The sum of two interior angles
Let the other interior angle = x
Hence:
115° = 55° + x
x = 115° - 55°

what would be the value of the autonomous expenditure multiplier if all taxes are autonomous
The value of the autonomous expenditure multiplier would be equal to 1 divided by (1 minus the tax multiplier).
The value of the autonomous expenditure multiplier would depend on the size of the tax multiplier.
The tax multiplier is the inverse of the marginal propensity to consume (MPC) from taxes, which is the portion of each dollar of taxes that households and businesses will spend.
If all taxes are autonomous, this means that taxes are not influenced by changes in income or other economic factors, and will remain constant.
In this case, the tax multiplier would be equal to the MPC from taxes.
The autonomous expenditure multiplier is calculated by dividing 1 by the marginal propensity to save (MPS), which is the portion of each dollar of income that households and businesses will save.
Since the MPC and MPS always add up to 1, we can use the tax multiplier to calculate the MPS from taxes as 1 minus the tax multiplier.
Therefore, the value of the autonomous expenditure multiplier would be equal to 1 divided by (1 minus the tax multiplier).

The sale tax on $25,000 car is $1375 what is the sales tax rate
Answer:
Tax rate is 5.5% because 1,375/25,000 is equal to 0.055 which is 5.5 in percentage form. To prove it you can multiply 25,000 by 0.055 and get 1,375.
Step-by-step explanation:
Sales tax rate is 5.5% of cost of car.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given,
Price of the car = $25000
Tax on car = $1375
Sales tax rate = ($1375/$25000)×100

An automatic filling machine is used to fill 2-litre bottles of cola. The machine’s output is known to be approximately Normal with a mean of 2.0 litres and a standard deviation of 0.01 litres. Output is monitored using means of samples of 5 observations.
Determine the upper and lower control limits that will include roughly 95.5 percent of the sample means.
If the means for 6 samples are 2.005, 2.001, 1.998, 2.002, 1.995 and 1.999, is the process in control?
The upper control limit (UCL) is approximately 2.0018 litres, and the lower control limit (LCL) is approximately 1.9982 litres, which would include roughly 95.5 percent of the sample means.
Now let's check if the process is in control using the given sample means:
To determine the upper and lower control limits for the sample means, we can use the formula:
Upper Control Limit (UCL) = Mean + (Z * Standard Deviation / sqrt(n))
Lower Control Limit (LCL) = Mean - (Z * Standard Deviation / sqrt(n))
In this case, we want to include roughly 95.5 percent of the sample means, which corresponds to a two-sided confidence level of 0.955. To find the appropriate Z-value for this confidence level, we can refer to the standard normal distribution table or use a calculator.
For a two-sided confidence level of 0.955, the Z-value is approximately 1.96.
Given:
Mean = 2.0 litres
Standard Deviation = 0.01 litres
Sample size (n) = 5
Using the formula, we can calculate the upper and lower control limits:
UCL = 2.0 + (1.96 * 0.01 / sqrt(5))
LCL = 2.0 - (1.96 * 0.01 / sqrt(5))
Calculating the values:
UCL ≈ 2.0018 litres
LCL ≈ 1.9982 litres
Therefore, the upper control limit (UCL) is approximately 2.0018 litres, and the lower control limit (LCL) is approximately 1.9982 litres, which would include roughly 95.5 percent of the sample means.
Now let's check if the process is in control using the given sample means:
Mean of the sample means = (2.005 + 2.001 + 1.998 + 2.002 + 1.995 + 1.999) / 6 ≈ 1.9997
Since the mean of the sample means falls within the control limits (between UCL and LCL), we can conclude that the process is in control.

Claire says that she can find the volume of any cylinder as long as she can measure the circumference and height is she correct
Answer:
Yes, she is correct. Volume of the cylinder is V = πr²h. Therefore we need height and radius to calculate the volume. Height is given and the radius can be calculated from the circumference.
Step-by-step explanation:
Volume of cylinder
\(V = \text{area of circle} \times \text{height}\\V = \pi r^2 \times h\)
For the volume of the cylinder we need the radius of the circle and height of the cylinder. The height is already known.
We can find the radius from the circumference.
Cirumference of the circle
\(C = 2 \pi r\)
We can get the radius from rearranging the equation.
\(r = \frac{C}{2 \pi}\)
Since C (circumference) is known we can easily calculate the radius.
With that we have all the needed information (height and radius) to calculate the volume of the cylinder.

the angle of elevation of the top of a tower from a point 42 metres away from it's base on level ground is 26 degrees. find the height of the tower.
Answer:
20.485 Meters
Step-by-step explanation:
So first you wanna draw a diagram. Start with the tower, then on the ground to the left (or right) draw a point. The point will be labeled as 42 m away from the tower. Now draw a line from that point to the top of the tower. This makes your triangle, and that angle you just drew that touches the point is 26 degrees.
Now, since you have a right triangle you can use trig. You know an angle and a side. Specifically, relative to the 26 degree angle you know the adjacent angle and want the opposite, which is the tower. So opposite and adjacent is tangent. So you set up tan(26) = o/42 where o is the opposite side.
So solving you get o = 20.485 meters

a bag of candy which has 100 pieces of candy has 15 yellow pieces, 17 green pieces, 18 red pieces, 20 blue pieces, and 30 orange pieces. what is the probability without replacing the piece you will grab 2 consecutive orange pieces?
The probability of grabbing 2 consecutive orange pieces is approximately 0.101.
Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it. Probability can range from 0 to 1, where 0 means the event to be an impossible one and 1 indicates a certain event.
The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.The probability of grabbing 2 consecutive orange pieces without replacement is calculated as:
\(\frac{30}{100}\) × \(\frac{29}{99}\) = 0.090/0.9 = 0.101010101...
Therefore, the probability of grabbing 2 consecutive orange pieces is approximately 0.101.

What are the quotient and remainder of (2x^4+5x^3-2x-8)/(x+3)
The quotient of (2x^4 + 5x^3 - 2x - 8) divided by (x + 3) is 2x^3 - x^2 + 3x - 7, and the remainder is 13.
To find the quotient and remainder, we can use polynomial long division.
First, we divide the leading term of the numerator, 2x^4, by the leading term of the denominator, x. This gives us 2x^3.
Next, we multiply the denominator, x + 3, by the quotient term we just found, 2x^3. We subtract this product, which is 2x^4 + 6x^3, from the numerator.
We then repeat the process with the new numerator, which is now -x^3 - 2x - 8.
Dividing the leading term of the new numerator, -x^3, by the leading term of the denominator, x, gives us -x^2.
We continue this process until the degree of the numerator is less than the degree of the denominator.
After finding the quotient, 2x^3 - x^2 + 3x - 7, and the remainder, 13, we can conclude our division.

an equilateral triangle and a square are inscribed in a circle as shown. $abc$ is isosceles. the triangle and square share a common vertex. what is the number of degrees in the measure of the angle indicated by the question mark?\
Note that the angle indicated by the question mark is 75°. See the explanation below.
What is the rationale for the above response?Given that the angle at the vertex that they (the equilateral triangle and the square share) is a right angle or 90 degrees.
This means that the middle angle of the equilateral triangle is 60° this is because an "equilateral" triangle has 3 equivalent sides and, therefore, 3 equivalent angles.
Since the sum of the 3 angles of ANY triangle is 180°, then 180/3 = 60° for each angle.
Because the angle at the vertex is "splitting" a right angle, or 90 degrees which belongs to the square, then that leaves 2 smaller angles on each side of the 60° angle,
or 90 - 60
=30/2
=15° each.
That is the top angle of the triangle you are trying to solve.
Therefore, since that small triangle is a right triangle, then: 180 - 90 - 15 =75°, which is the angle with a question mark (?)

Ivan and his little brother made up a game using coins. They flip the coins towards a cup and receive points for every one that makes it in. Ivan starts with 20 points, and his little brother starts with 16 points. Ivan gets 2 points for every successful shot, and his brother, since he is younger, gets 4 points for each successful shot. Eventually, the brothers will have a tied score in the game. How many points will they both have? How many additional shots will each brother have made?
Answer:
24 points
2 shots
Step-by-step explanation:
Ivan :
Starting point = 20
Points per success = 2
Brother :
Starting point = 16
Points per success = 4
Let number of successful shots = x
20 + 2x = 16 + 4x
2x - 4x = 16 - 20
-2x = - 4
x = 2
Number of additional shots made = x = 2
Number of points they both have :
20 + 2x = 20 + 2(2) = 20 + 4 = 24 points
16 + 4x = 16 + 4(2) = 16 + 8 = 24 points
