The length of QR is (1/2) * (4a + 6b).

The question is asking for the length of QR, the midsegment of equilateral triangle MNP. To find the length of QR, we need to find the length of one side of the equilateral triangle first.
The perimeter of an equilateral triangle is equal to the sum of the lengths of all three sides. In this case, the perimeter is given as 12a + 18b.
Since all three sides of an equilateral triangle are equal, we can set up an equation:
12a + 18b = 3s, where s is the length of one side of the triangle.
To find QR, we need to find the length of s first.
Dividing both sides of the equation by 3, we get:
4a + 6b = s
Now that we know the length of one side of the equilateral triangle, we can find the length of QR.
A midsegment of a triangle is a line segment that connects the midpoints of two sides of the triangle. In an equilateral triangle, the midsegment is also parallel to the third side and half its length.
So, QR is parallel to one side of the equilateral triangle and half its length.
Therefore, QR is equal to (1/2) * s.
Substituting the value of s from the equation above, we get:
QR = (1/2) * (4a + 6b)

False. The frequency polygon and the histogram are two different ways to represent data, and they have distinct characteristics.

A frequency polygon is a line graph that displays the distribution of a quantitative variable. It shows the frequency of each value or class interval on the horizontal axis and the corresponding frequencies on the vertical axis. The points on the graph are connected to form a line, which gives a visual representation of the data distribution.

Answer:

Their speed is 32 km/h.

Step-by-step explanation:

Since they're at the same speed, we can assign a variable to their speed called "x". When the first car increases its speed by 1 km/h, its new speed is "x + 1", while the other car decreases its speed by 10 km/h, so its new speed is "x - 10". The distance's formula can be expressed as below:

\(\text{distance} = \text{speed}*\text{time}\\\)

With the modifications to their speed, the distance the first car covers in 2 h and the distance the second car covers in 3 h is shown below:

\(\text{distance}_{car1} = (x + 1)*2 \\\text{distance}_{car1} = 2*x + 2\)

\(\text{distance}_{car2} = \text{speed}*\text{time}\\\text{distance}_{car2} = (x - 10)*3\\\text{distance}_{car2} = 3*x - 30\)

Since the distance covered by them must be the same, we can find the value of x that makes the expressions equal.

\(2*x + 2 = 3*x - 30\\2*x - 3*x = -30 -2\\-x = -32\\x = 32\)

Their speed is 32 km/h.

Answer:

R:{-1,14,26}

Step-by-step explanation:

The domain of a function is all the x-values of the function. The range of a function is all the y-values of the function. Therefore, we must plug in every x-value in the function to get our outputs to create our range:

Given: y=3x+14

When x=-5:

y=3(-5)+14

y=-15+14

y=-1 (this is the first point of the range)

When x=0:

y=3(0)+14

y=0+14

y=14 (this is the second point of the range)

When x=4:

y=3(4)+14

y=12+14

y=26 (this is the last point of the range)

Therefore, our range is R:{-1,14,26}

The range for the given domain {-5, 0, 4} in the equation y = 3x + 14 is

{ -1, 14, 26 }.

We have,

To find the range for the given domain of {-5, 0, 4} in the equation

y = 3x + 14, we substitute each value of the domain into the equation and determine the corresponding range values.

When x = -5:

y = 3(-5) + 14

y = -15 + 14

y = -1

When x = 0:

y = 3(0) + 14

y = 0 + 14

y = 14

When x = 4:

y = 3(4) + 14

y = 12 + 14

y = 26

Therefore,

The range for the given domain {-5, 0, 4} in the equation y = 3x + 14 is

{ -1, 14, 26 }.

Answer:

slope = -2

y-intercept = 2

equation: y = -2x + 2

Step-by-step explanation:

The equation of a line is

y = mx + b

We need to find the slope, m, and the y-intercept, b.

The graph crosses the y-axis at y = 2, so the y-intercept, b, equals 2.

Now we have

y = mx + 2

slope = m = rise/run

We see points (1, 0) and (0, 2) on the graph. Starting at (1, 0), we go up 2 units. That is a rise of 2. Then we go 1 unit left. That is a run of -1.

slope = m = rise/run = 2/(-1) = -2

The slope is -2.

The equation is

y = -2x + 2

Answer:

y=-2x+2

Step-by-step explanation:

Using rise over run the line travels down 2 and right one from one point to another giving u -2/1 or -2 as the slope and it passes through the y-axis at 2 giving you a y-intercept of 2 and the equation y=-2x+2.

The limit of the function lim(θ→0) sin(2θ)/θ can be estimated by using a graph.

To estimate this limit graphically, you would first plot the function y = sin(2θ)/θ on a graph with the x-axis representing θ and the y-axis representing the function value. Since θ is measured in radians, make sure your graph is set to radians as well. As θ approaches 0, observe the behavior of the function.

Based on the graph, you will notice that the function approaches a value of 2 as θ approaches 0. Therefore, lim(θ→0) sin(2θ)/θ ≈ 2.

Danielle says that her set of numbers are integers the statement is wrong as the set contain decimal number because decimal numbers are not integers, so option C is correct.

All whole numbers and negative numbers are considered integers. This means that if we combine negative numbers with whole numbers, a collection of integers results.

Given:

The value of S, which represents the length of each side of the square, is 4 miles.

To find the value of S, we need to determine the length of each side of the square. Given that the perimeter of the square is 16 miles, we can use the formula for the perimeter of a square, which is 4 times the length of a side.

Perimeter = 4 × S

Given that the perimeter is 16 miles, we can substitute this value into the equation:

16 = 4 × S

To solve for S, we divide both sides of the equation by 4:

16 ÷ 4 = S

4 = S

Therefore, S, which stands for the square's side lengths, has a value of 4 miles.

So, S = 4 miles.

This means that each side of the square measures 4 miles, and the square has equal sides and right angles at each corner.

Let's write the likelihood of a promotion as P(promotion) and the likelihood of a rise as P(raise). The following details are sent to us:

P (promotion) = 0,40 P (promotion or raise) 0,72 P (promotion and raise) 0,25The inclusion-exclusion concept can be used to calculate the likelihood of receiving a rise. This rule states that the probability of two events (A or B) coming together is equal to the sum of each event's individual probabilities less the likelihood that A and B will come together.

P(promotion or raise) equals P(promotion) + P(raise) – P(promotion andraise).

By substituting the specified values, we obtain:

0.7 = 0.40 + P (b) - 0.25

We can rewrite the equation to isolate P(raise) as follows:P(raise) = 0.72-0.40+0.25

P(rise) = 0.57

The likelihood of receiving a rise is therefore 0.57, or 57%.

In perimeter, The cost to frame Joy's math certificate in a fancy frame is $138.00.

The dimensions of Joy's math certificate are 10 inches tall and 13 inches wide.

Joy wants to frame it in a fancy frame that costs $3.00 per inch.

To determine the total cost of framing the certificate, we need to find its perimeter and then multiply that by the cost per inch.

The perimeter of the certificate is:

Perimeter = 2 × (height + width)

Substituting the given values, we get:

Perimeter = 2 × (10 + 13)Perimeter = 46 inches

Therefore, the total cost of framing Joy's math certificate is:

Total cost = Perimeter × Cost per inch

Total cost = 46 × 3.00Total cost = $138.00

The Year 4, Q1 forecast using exponential smoothing with α = 0.35 and an initial forecast of 417, along with seasonality, is 335.88.

Exponential smoothing is a forecasting technique that takes into account both the historical demand and the trend of the data. It is calculated using the formula:

Forecast = α * (Demand / Seasonal Index) + (1 - α) * Previous Forecast

Initial forecast (Previous Forecast) = 417

α (Smoothing parameter) = 0.35

Demand for Year 4, Q1 = 307

Seasonal Index for Q1 = 0.762

Using the formula, we can calculate the Year 4, Q1 forecast:

Forecast = 0.35 * (307 / 0.762) + (1 - 0.35) * 417

        = 335.88

Therefore, the Year 4, Q1 forecast using exponential smoothing with α = 0.35 and an initial forecast of 417, along with seasonality, is 335.88.

The forecasted demand for Year 4, Q1 using exponential smoothing is 335.88.
