Given D,E midpoints
Answers
Answer: B
Step-by-step explanation:
Given that DE is the mid point. Since DE is the midpoint, it will be equal to the half value of BC. That is,
DE = 1/2 × BC
Where
DE = 3x - 5
BC = 26
Substitute the values into the equation
3x - 5 = 1/2 × 26
3x - 5 = 13
Collect the like terms
3x = 13 + 5
3x = 18
x = 18/3
X = 6
The correct option is B
if the units for x are feet and the units for a(x) are pounds per foot, what are the units for da dx ?
Answers
The units for da/dx are pounds per foot squared.
The units for da/dx would be pounds per foot squared. This is because da/dx represents the rate of change of the function a(x), which has units of pounds per foot, with respect to x, which has units of feet. When we take the derivative of a(x), we essential do division of the change in a(x) by the change in x.
The change in a(x) has units of pounds, and the change in x has units of feet. Therefore, the units for da/dx are pounds per foot squared.
To further explain this, imagine that a(x) represents the weight of a beam that is x feet long. The units for a(x) would be pounds per foot, as it gives us the weight of the beam per unit of length. The derivative of a(x), or da/dx, would give us the rate at which the weight of the beam changes as we increase its length by one foot.
This rate of change would be in units of pounds per foot squared, as we are dividing the change in weight (pounds) by the change in length (feet squared).

you have a total of 21 coins that are nickels and quarters. the total is $3.25. How many nickels do you have? and quarters?
Answers
Answer:
There are 10 nickels and 11 quarters in the jar.
Step-by-step explanation:
Given that:
Total coins = 21
Total value = $3.25 = 3.25*100 = 325 cents
One nickel = 5 cents
One quarter = 25 cents
Let,
x be the number of nickels
y be the number of quarters
According to given statement;
x+y=21 Eqn 1
5x+25y=325 Eqn 2
Multiplying Eqn 1 by 5
5(x+y=21)
5x+5y=105 Eqn 3
Subtracting Eqn 3 from Eqn 2
(5x+25y)-(5x+5y)=325-105
5x+25y-5x-5y=220
20y=220
Dividing both sides by 20
\(\frac{20y}{20}=\frac{220}{20}\\y=11\)
Putting y=11 in Eqn 1
x+11=21
x=21-11
x=10
Hence,
There are 10 nickels and 11 quarters in the jar.

A water sample shows 0.063 grams of some trace element for every cubic centimeter of water. Savannah uses a container in the shape of a right cylinder with a radius of 6 cm and a height of 17.6 cm to collect a second sample, filling the container all the way. Assuming the sample contains the same proportion of the trace element, approximately how much trace element has Savannah collected? Round your answer to the nearest tenth.
Answers
The volume of a cylinder with radius r and height h is given by:
\(V=\pi\cdot h\cdot r^2\)For r = 6 cm and h = 17.6 cm, we have:

The perimeter of the smaller polygon is 60 inches, and the ratio of the side lengths is 3/5. Find the perimeter of the larger polygon.
Answers
100 inches
Let's use "x" to represent the length of a side of the smaller polygon, and let's use "y" to represent the corresponding length of a side of the larger polygon. We're told that the ratio of the side lengths is 3/5, so we can set up the equation:
y/x = 5/3
We're also told that the perimeter of the smaller polygon is 60 inches, so we can set up another equation using the fact that the smaller polygon has "n" sides:
nx = 60
Now, we want to find the perimeter of the larger polygon, which also has "n" sides. We can use the equation we set up earlier to write "y" in terms of "x":
y/x = 5/3
y = (5/3)x
Now we can substitute this expression for "y" into the formula for the perimeter of the larger polygon:
Perimeter of larger polygon = nx = n(5/3)x = (5/3)(nx) = (5/3)(60) = 100
So the perimeter of the larger polygon is 100 inches.

Find the period and the amplitude of the periodic function. I'm awful with graphs :(
Answers
A period is the difference in x over which a sine function returns to its equivalent state and the amplitude is A/5.
Amplitude:
The amplitude of a periodic variable is a measure of its change over a period of time, such as a temporal or spatial period. The amplitude of an aperiodic signal is its magnitude compared to a reference value. There are various definitions (see below) of amplitude, which is any function of the magnitude of the difference between the extreme values of a variable. In the previous text, the phase of a periodic function is called the amplitude.
X = A sin (ω[ t - K]) + b
A is the amplitude (or peak amplitude),
x is the oscillating variable,
ω is angular frequency,
t is time,
K and b are arbitrary constants representing time and displacement respectively.
According to the Question:
An equation does not have an amplitude. This "equation" represents the formula of a vibration, and was better written as:
X= A/5* sin(1000.t + 120)
These oscillations have a certain amplitude. X values can vary from minimum to maximum. Normally, the stop position of the oscillation is X=0. In this case, we can see that the maximum occurs when the sine is +1 and the minimum occurs when the sine is -1.
For theses cases X= A/5 respectively -A/5.
Therefore,
The amplitude is A/5.
For formulas of this type, the term in front of the sinus (or cosine) is equal to the amplitude.

the figure at the right was made with 4 triangles. an architect made a long figure like this using 70 triangles. each side of each triangle is 1 meter long. what is the perimeter of the figure made with 70 triangles
Answers
To find the perimeter of the figure made with 70 triangles, we need to first find the perimeter of one triangle and then multiply it by 70. Since each side of each triangle is 1 meter long, the perimeter of one triangle is 3 meters (1+1+1).
Therefore, the perimeter of the figure made with 70 triangles is 70 multiplied by 3, which equals 210 meters.
The original figure consists of 4 triangles, which means the perimeter is the sum of the lengths of the 12 sides of those triangles, each with a length of 1 meter. Therefore, the perimeter of the original figure is 12 meters.
To find the perimeter of the figure made with 70 triangles, we can use the fact that each additional row of triangles adds 3 meters to the perimeter. Since the original figure has 4 triangles and the long figure has 70 triangles, there are 66 additional rows of triangles. Therefore, the perimeter of the long figure is:
12 meters + (66 rows x 3 meters/row) = 12 meters + 198 meters = 210 meters.
Thus, the perimeter of the figure made with 70 triangles is 210 meters.

The population regression equation for accuracy and ball inflation based on Model C is:
Y = 51.756 - 5.354X + 0.185X^2 - 0.001X^3 + εi
Based on the given output, the population regression equation for accuracy (Y) and ball inflation (X) is:
Y = Bo + BiX + B2X^2 + B3X^3 + εi
where Bo is the intercept, Bi, B2, and B3 are the coefficients for the first, second, and third order terms of X, respectively, and εi is the error term.
The output shows the estimates for the coefficients in three different models. Model A only includes the first order term, Model B includes the first and second order terms, and Model C includes the first, second, and third order terms.
Based on the t-statistic and p-level values, we can see that Model C is the most statistically significant. Therefore, we can use the estimates from Model C to define the population regression equation.
The estimates for the coefficients in Model C are:
Bo = 51.756
Bi = -5.354
B2 = 0.185
B3 = -0.001
Thus, the population regression equation for accuracy and ball inflation based on Model C is:

The provided output shows the results of estimating three different regression models (Model A, Model B, and Model C) with different sets of independent variables.
Model A includes only a linear term for inflation (Inflation coefficient = -1.181), while Model B includes both a linear and a quadratic term for inflation (Inflation coefficient = -4.941; Inflation² coefficient = 0.102). Model C also includes a linear and a quadratic term for inflation, as well as an interaction term between the two (Inflation coefficient = -5.354; Inflation² coefficient = 0.185; Inflation * Inflation² coefficient = -0.001).
Since Model B and Model C both include a quadratic term for inflation, either of them could potentially be the population regression equation that best represents the curvilinear relationship between ball inflation and accuracy. However, Model C is preferred over Model B because it also accounts for the interaction between the linear and quadratic terms of inflation, which could potentially affect the curvature of the relationship.
Therefore, the population regression equation that best represents the curvilinear relationship between ball inflation and accuracy is:
Accuracyi = bo + b1Inflationi + b2Inflation²i + b3(Inflationi * Inflation²i) + εi
where bo is the intercept, b1 is the coefficient for the linear term of inflation, b2 is the coefficient for the quadratic term of inflation, b3 is the coefficient for the interaction term between the two, and εi is the error term.
Option C, Accuracyi = bo +b1Inflationi + b2Inflation, is incorrect because it only includes linear term for inflation, while we know that a curvilinear relationship is suspected.

The statement "Player 3 is more likely to hit the ball than Player 2 because P(Player 3) > P(Player 2)" is true we get by finding probabilities of each played and comparing them.
We need to convert the probabilities to decimals or fractions to compare them.
Player 1: 7/11 = 0.64
Player 2: 6/9 = 0.67
Player 3: 5/7 = 0.71
Comparing the probabilities, we see that Player 3 has the highest probability of hitting the ball, followed by Player 2, and then Player 1.

What is the approximate length of minor arc LM? Round to the nearest tenth of a centimeter
Answers
The approximate length of minor arc LM is 6.3 centimeters.
To find the length of a minor arc, we need to use the formula: length of minor arc = (angle measure / 360) x circumference of the circle.
In this case, we know that the angle measure of minor arc LM is 70 degrees, since it is given in the diagram. We also know that the circumference of the circle is 20π centimeters (since the diameter is 20 centimeters).
Using the formula, we can calculate the length of minor arc LM as follows:
length of minor arc LM = (70 / 360) x 20π
≈ 0.1944 x 20π

Answers
the depth perception cue based on the observation that parallel lines converge in the distance is that the depth perception cue based on the observation that parallel lines converge in the distance is known as linear perspective. This is a monocular cue, meaning it can be perceived with just one eye.
When looking at a scene, our brain uses the visual information provided by our eyes to determine depth and distance. Linear perspective is a cue that relies on the way that objects appear to shrink in size and converge towards a vanishing point as they move further away from the viewer. This is why parallel lines, such as the sides of a road or railway tracks, appear to meet at a point in the distance.
Linear perspective is a powerful visual cue that allows us to accurately perceive depth and distance in a scene. It is commonly used in art and architecture to create a sense of depth and realism, and is a crucial component of our visual perception.

The drive-thru that is able to estimate their wait time more consistently and why is: A. Burger Quick, because it has a smaller IQR.
Which drive-thru is able to estimate their wait time more consistently and why?The IQR is a measure of the spread of the middle 50% of the data, and is calculated as the difference between the third quartile (Q3) and the first quartile (Q1). A smaller IQR indicates that the data is less spread out around the median, and therefore more consistent.
In this case, the IQR for Super Fast Food is 15.5 - 12 = 3.5, while the IQR for Burger Quick is 24 - 15.5 = 8.5. Therefore, Burger Quick has a larger range (24 - 2 = 22) than Super Fast Food (27 - 3 = 24), but a smaller IQR, indicating that their wait time estimates are more consistent.
Therefore Quick is able to estimate their wait time more consistently because it has a smaller interquartile range (IQR).
