What is area of triangle?

The area occupied by a triangle is known as area of triangle. The area if computed as 1/2*base*height

We are given the, base of 1500 feet and a height of 600 feet

Hence the area of triangle can be given as

Area= 0.5*1500*600

Area= 450000 ft^2

Now 1 acre costs as 43560 sqft

Hence the area of triangle in acres is

Area in acres = \(\frac{450000}{43560}\)

Area in acres= 10.33

Hence total amount for which the piece of land is sold = 10.33*900

Total amount= $9297

Now we have to find the 7% of this amount

Hence

\(=\frac{9297*7}{100}\\=650.82\)

Hence the amount received as commission is $650.82

Depending on skill level either of them could win, for example if the 10 players are able to overwhelm the 8 players they will win, but if the 8 players have better players they could win, depending on their skill, even though the 10 player team has a better chance to win, the 8 player team could win.

The simplified expression for 2a + 5b - 4b - 1 is 2a + b - 1.

To simplify this expression, we first combine like terms. We have 5b and -4b, which combine to give us b. We also have 2a and no other like terms, so we leave that as is. Finally, we have the constant term -1, which remains the same. Thus, our simplified expression is 2a + b - 1.

It is important to note that when combining like terms, we only combine terms with the same variables and same exponents. In this case, we had two terms with the variable b, but no other terms with that variable. Similarly, we had one term with the variable a, and no other terms with that variable. This allowed us to combine like terms and simplify the expression.

Answer:

Step-by-step explanation:

that is incorrect.

if it were to be equal, one side should equal each other when multiplied to make the ratio equal.

20-5x=40-10x (when multiplied by 2 on each side)

It CANNOT equal 50, if it were there would not be -10x

20-5x=100-25x

DIVIDE BY 2 to get 50 WOULD GIVE:

20-5x=50-17.5x

Answer:

Yes

Step-by-step explanation:

solve the equation for x , then evaluate and compare both sides

20 - 5x = 50 - 10x ( add 10x to both sides )

20 + 5x = 50 ( subtract 20 from both sides )

5x = 30 ( divide both sides by 5 )

x = 6

then

left side = 20 - 5x = 20 - 5(6) = 20 - 30 = - 10

right side = 50 - 10x = 50 - 10(6) = 50 - 60 = - 10

since both sides are equal then

20 - 5x = 50 - 10x is true

The coordinates of K are (8,3).

There is a line segment JK with M as its midpoint. This means the length of JM = length of MK.

Also the coordinates of J is (-4,7) and the coordinates for M are (2,5).

As M is the midpoint, the x-distance and y-distance between (-4,7) and (2,5) are same as that between (2,5) and K.

x- distance between (-4,7) and (2,5) = 2- (-4) = 6

So x- coordinate of K = 2+6 = 8

y-distance between (-4,7) and (2,5) = 5-7 = -2

There is one value greater than 148.25, which is 96. the value of 96 is considered an outlier in this Dataset.

To identify outliers in a dataset, we need to first calculate the interquartile range (IQR) and then use the following rule:Any data value less than Q1 - 1.5 x IQR or greater than Q3 + 1.5 x IQR is considered an outlier.

To find Q1 and Q3, we first need to order the data:

21, 40, 52, 58, 72, 75, 96

The median of the entire dataset is (58 + 72)/2 = 65, so Q2 (the second quartile) is 65.

The lower quartile Q1 is the median of the lower half of the data, which is:

21, 40, 52, 58

The median of this data is (40 + 52)/2 = 46, so Q1 is 46.

The upper quartile Q3 is the median of the upper half of the data, which is:

72, 75, 96

The median of this data is (75 + 96)/2 = 85.5, so Q3 is 85.5.

Now we can calculate the interquartile range (IQR):

IQR = Q3 - Q1 = 85.5 - 46 = 39.5

Using the rule for outliers, any data value less than Q1 - 1.5 x IQR or greater than Q3 + 1.5 x IQR is considered an outlier.

Q1 - 1.5 * IQR = 46 - 1.5 x 39.5 = -23.25

Q3 + 1.5 * IQR = 85.5 + 1.5 x 39.5 = 148.25

Therefore, any data value less than -23.25 or greater than 148.25 is an outlier.

In this case, there are no values less than -23.25, but there is one value greater than 148.25, which is 96. Therefore, the value of 96 is considered an outlier in this dataset.

the unit normal vector to the curve with vector equation \vec r \, (t) =<1^t,\ln(4/t^2), \, \ln(e/(t^4)) > r (t)=<1 t ,ln(4/t 2 ),ln(e/(t 4 ))> at the point where t=2t=2 is \vec n = <0,0,-1>

A unit normal vector is a normal vector with magnitude 1, and it points in the direction that is perpendicular to the tangent to the curve at a given point.

To determine the unit normal vector to a curve, it's important to find the tangent first and then find the normal. In this case, we're looking for the unit normal vector to the curve with the vector equation \vec r (t) =<1^t,\ln(4/t^2), \ln(e/(t^4)) > at the point where t = 2.

To find the unit normal vector to the curve with the vector equation \vec r (t) =<1^t,\ln(4/t^2), \ln(e/(t^4)) > at the point where t = 2, it is necessary to find the tangent to the curve and then find the normal. This is a crucial step in understanding the geometry of curves in 3D space.

To find the tangent to the curve, we'll differentiate the vector equation with respect to t and evaluate it at t = 2. The derivative of \vec r (t) is given by:

d\vec r/dt = <1, -2t^-3, -4e^-t^-4>

So the tangent to the curve at t = 2 is:

d\vec r/dt = <1, -2(2)^-3, -4e^-2^-4> = <1, 1.5, -1.648721>

Next, we'll find the normal to the tangent by taking the cross product of the tangent with a fixed vector, for example, the unit vector i = <1,0,0>. The cross product of two vectors results in a vector that is perpendicular to both of them.

The cross product of the tangent and the unit vector i is given by:

\vec T x \vec i = <1, 1.5, -1.648721> x <1,0,0> = <0,0,-1.5>

Since the magnitude of the normal is not 1, we'll normalize it by dividing it by its magnitude:

\vec n = \vec T x \vec i / ||\vec T x \vec i|| = <0,0,-1.5> / ||<0,0,-1.5>|| = <0,0,-1>

So the unit normal vector to the curve with the vector equation \vec r (t) =<1^t,\ln(4/t^2), \ln(e/(t^4)) > at the point where t = 2 is given by:

\vec n = <0,0,-1>

This is the unit normal vector that points in the direction that is perpendicular to the tangent to the curve at t = 2. The magnitude of 1 ensures that it's a unit vector and the direction points towards the normal direction.

Answer:

Length = 8 meters

Width = 5 meters

Step-by-step explanation:

2*(3 + (1/4)L + L) = 26 meters

1/4L + L = 26/2 - 3

1/4L + 4/4L = 10

5/4L = 10

L = 10 * 4/5

L = 40/5 = 8 meters

W = 3 + 1/4 L

W = 3 + 1/4 *8

W = 3 + 2

W = 5 meters

Hey there! I'm happy to help!

Let's write this out as a system of equations. We will have W be the width and L be the length.

W=0.5L+3

2L+2W=516

Since we know that W is equal to 0.5L+3, we can swap the W in the second equation with 0.5L+3 so we can solve for L!

2L+2(0.5L+3)=516

We use the distributive property to undo the parentheses.

2L+L+6=516

We combine like terms.

3L+6=516

We subtract 6 from both sides.

3L=510

We divide both sides by 3.

L=170

Now, we know that the width is 3 meters more than half the length. So, we take 1/2 of 170, which is 85, and then we add three, giving us 88.

So, our length is 170 meters and the width is 88 meters.

Step-by-step explanation:

The inputs or features that are fed into the model and with which the model is expected to make a prediction for the linear regression are x.

Linear regression is a statistical approach to establish a relationship between dependent and independent variables. In linear regression, the model is f_{w,b}(x) = wx + bfw,b​(x)=wx+b. The independent variable (x) is the feature that is fed into the model and with which the model is expected to make a prediction.

In the equation f_{w,b}(x) = wx + bfw,b​(x)=wx+b, w is the weight of the input feature x, and b is the bias term that makes an adjustment in the output. These parameters w and b are learned through training the model with input-output examples.

The purpose of linear regression is to create a mathematical model that defines the relationship between the input feature x and the output y. The model is then used to predict the outcome for new data points or to understand the relationship between the variables.

Bryant Industries uses forecasting to estimate the number of orders that will be placed by their customers. The table below gives the sales figures for the last four months.Month2345Sales92491942004There are different forecasting techniques used by companies like Bryant Industries to predict future sales.

One of the most widely used methods is the time-series method. This method is particularly useful when the demand for a product or service changes over time and when there are no external factors that affect the sales. In this case, we can use a time-series method called the moving average to estimate future sales. The moving average is a time-series method that uses the average of past sales data to estimate future sales. It is particularly useful when there are no external factors that affect the sales. In this case, we can use a 3-month moving average to estimate future sales. The 3-month moving average is calculated as follows: (924 + 919 + 420) / 3 = 754.33. This means that we can expect sales of around 754 units next month. The moving average method is easy to use and is a good way to get a quick estimate of future sales. However, it has some limitations. For example, it does not take into account external factors that may affect sales, such as changes in the economy or in consumer behavior.

In conclusion, Bryant Industries can use the moving average method to estimate future sales. However, they should also consider other factors that may affect sales, such as changes in the economy or in consumer behavior. By doing so, they can make more accurate forecasts and improve their overall performance.

The estimated average speed of the pontoon boat when the engine speed is 2800 RPMs is approximately 20.5 miles per hour.

Explain about linear equation ?

A linear equation is an equation between two variables, x and y, that results in a straight line when plotted on a graph. The equation is of the form y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line intersects the y-axis).

The slope of the line determines how steep the line is. If the slope is positive, the line goes up as x increases. If the slope is negative, the line goes down as x increases. The magnitude of the slope tells us how much the line changes in y for each unit change in x.

According to the question:
To find a model for the data, we can plot the given points on a graph and see if there is a linear relationship between the two variables.

After plotting the points, we can see that there is a linear relationship between x and y. We can use linear regression to find the equation of the line that best fits the data. The equation of the line is of the form y = mx + b, where m is the slope and b is the y-intercept.

Using a calculator or software, we find that the equation of the line that best fits the data is y = 0.669x + 1.466.

To estimate the average speed of the pontoon boat when the engine speed is 2800 RPMs, we can substitute x = 28 into the equation and solve for y:

y = 0.669(28) + 1.466

y ≈ 20.5
