Calculate the residuals for your scatterplot in step 2d.
In statistics, a residual is defined as the difference between the predicted value of an outcome variable and the observed value of that variable. Residuals are used to evaluate how well a regression model fits the data.In order to calculate the residuals for a scatterplot, follow these steps:
Step 1: Plot the data on a scatterplot.
Step 2: Perform a regression analysis on the data to find the equation of the regression line. This equation should take the form y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept.
Step 3: Using the equation of the regression line, calculate the predicted value of y for each data point in the scatterplot.
Step 4: Subtract each predicted value of y from the actual value of y for each data point in the scatterplot. This difference is the residual for that data point.
Step 5: Plot the residuals on a new scatterplot. The x-axis of this scatterplot should be the independent variable, and the y-axis should be the residual values.
Step6: This scatterplot is called a residual plot.Residuals are useful for identifying patterns in data that the regression model fails to capture. If the residuals are randomly scattered around the horizontal axis, then the regression model is a good fit for the data. If there are clear patterns in the residual plot, then the regression model may not be a good fit for the data and further analysis is required.

At a small tool-hire company, the estimated rate of increase in the maintenance cost of power drills is given by
The maintenance cost at 10 weeks is gotten by substituting t = 10 into the given equation.
Evaluating a FunctionTo evaluate the given function at t = 10, we simply need to do is substitute the value of t into the equation and evaluate.
\(c(t) = 2e^2^t + 2t + 19\\\)
But when t = 10
\(c(t) = 2e^2^t + 2t + 19\\\\c(10) = 2e^2^(^1^0) + 2(10) + 19\\c(10) =2e^2^0 + 39\)

Campsite fees
(per day)
Tent ...... .. $15.00
Caravan ....... $25.00
The sign shows the fees charged at a campsite.
Today there are 54 tents and 18 caravans on the site.
Calculate the fees charged today.
Answer:
1260
Step-by-step explanation:
Tents: 15×54=810
Caravans: 25×18=450
450+810=1260
Answer:
$1260
Step-by-step explanation:
Campsite Fees:
Tent - $15 (per day)
Caravan - $25 (per day)
No. of Tents and Caravans today:
Tents - 54
Caravan - 18
Total fees for Tent = 15 x 54
= $810.
Total fees for Caravan = 25 x 18
= $450.
Fees altogether for Today = Total fees for Tent + Total fees for Caravan
= $810 + $450
= $1260

The expression (sinx + cosx)^2 + (sinx - cosx)^2 simplifies to
4 + 2sinxcosx.How to simplify the identityTo simplify the expression (sinx + cosx)^2 + (sinx - cosx)^2 using trigonometric identities, we can expand and simplify the expression.
Expanding the squared terms
(sin^2x + 2sinxcosx + cos^2x) + (sin^2x - 2sinxcosx + cos^2x)
Using the trigonometric identity sin^2x + cos^2x = 1, we can simplify further:
(1 + 2sinxcosx + 1) + (1 - 2sinxcosx + 1)

An art collage includes a red paper triangle with one side length of 3.4 inches and a second side length of 8.1 inches.
. Imagine a game of 3 players where exactly one player wins in the end and all players have equal chances of being the winner. The game is repeated four times. Find the probability that there is at least one person who wins no games. Hint: Consider the events Ai in which person i wins no games and use the inclusion-exclusion formula.
Answer:
5/9
Step-by-step explanation:
Number of players = 3
number of times game is repeated = 4
P( any person wins a game ) = 1/3
P ( any person does not win a game ) = 1 - 1/3 = 2/3
P ( any person wins no game in 4 attempts ) = ( 2/3 )^4 = 16/81
Note : each player has equal chance of winning
Find the probability that there is at least one person who wins no games
lets represent the probability of each player not wining a game with alphabet A
A1 = player 1 wins no game
A2 = player 2 wins no game
A3 = players 3 wins no game
Applying the inclusion-exclusion formula
P( A1 ∪ A2 U A3 ) = P(A1 ) + P(A2) + P(A3) - P( A1 ∩ A2 ) - P( A2 ∩ A3 ) - P( A1 ∩ A3 ) + P( A1 ∩ A2 ∩ A3 )
where
P( A1 ∩ A2 ) = P( A1 wins all games )
P ( A1 wins all games in 4 attempts ) = ( 1/3 )^4 = 1/81
P( A1 ∩ A2 ∩ A3 ) = P ( no players wins any game in 4 attempts ) = 0
Hence
P( A1 ∪ A2 U A3 ) = 16/81 + 16/81 + 16/81 - 1/81 - 1/81 - 1/81 - 0 = 5/9
The probability should be\(5\div 9\)
Calculation:Number of players = 3
number of times game is repeated = 4
P( any person wins a game ) = \(1\div 3\)
P ( any person does not win a game ) = \(1 - 1\div 3 = 2\div 3\)
P ( any person wins no game in 4 attempts ) = \(( 2\div 3 )^4 = 16\div 81\)
Now
A1 = player 1 wins no game
A2 = player 2 wins no game
A3 = players 3 wins no game
So,
P( A1 ∪ A2 U A3 ) = P(A1 ) + P(A2) + P(A3) - P( A1 ∩ A2 ) - P( A2 ∩ A3 ) - P( A1 ∩ A3 ) + P( A1 ∩ A2 ∩ A3 )
\(= 16\div 81 + 16 \div81 + 16\div 81 - 1 \div 81 - 1 \div 81 - 1 \div81 - 0 \\\\= 5 \div9\)

How can we develop a margin of error through the use of simulation models for random sampling
When using simulation models for random sampling, we can develop the margin of error by multiplying the critical value by the standard error.
What is the margin or error?This is a measure of the error that we get when we use a random sampling model.
It can be found by the formula:
= Critical value x Standard error
If using a z-test, the critical value would be z and the standard error would be (σ / √n). The margin or error would therefore be:
= z (σ / √n)

What is triangle?In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space). In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle.
All triangles are contained in a single plane if all geometry is on the Euclidean plane, but in higher-dimensional Euclidean spaces, this is no longer the case.
The definition of the terminology used to classify triangles can be found on the first page of Euclid's Elements, which dates back more than two thousand years. In modern classification, names are either directly transliterated from Euclid's Greek or translated from Latin.
Hence, To prove congruence using S Theorem, you must understand that pairs of two angles are congruent as well as the pair of sides that are next to one of the specified angles.

find the measurement of angle 1
Answer:
100 degrees.
Step-by-step explanation:
The missing angle on the bottom triangle is equal to 80 degrees because a triangle's interior angles add up to 180deg.
Think of that middle angle between angle 1 and the two triangles as a full 360deg. Since VAT (Vertical Angle Theorem) suggests that vertical angles are equal, 160deg of that 360deg are taken up by the missing angles in the triangles. That leaves 200deg to split between angle 1 and its equal vertical angle, which means angle 1 is 1/2 of 200, or 100deg.
