A data set contains three points, and two of the residuals are -10 and 20.
What is the third residual?
Answers
If a data set contains three points, and two of the residuals are -10 and 20, the third residual is 10 (option B).
What is a residual?A residual is the difference between the observed value and the estimated value of the quantity of interest.
The residual of a data points should normally sum up to zero (0). This means the following applies:
-10 + 20 + x = 0
x = 10
Therefore, if data set contains three points, and two of the residuals are -10 and 20, the third residual is 10.

The different coordinates after respective rotation are:
1) A'(2, 0)
2) A'(0, -2)
3) A'(-2, 0)
What are the coordinates after rotation?There are different methods of transformation such as:
Translation
Rotation
Dilation
Reflection
Now, the coordinate of the given point A is: A(0, 2)
1) The rule for rotation of 90 degrees clockwise is:
(x, y) →(y,-x)
Thus, we have:
A'(2, 0)
2) The rule for rotation of 180 degrees is:
(x, y) → (-x,-y)
Thus, we have:
A'(0, -2)
3) The rule for rotation of 180 degrees is:
(x, y) → (-y,x)

Answers
The simplified equation is (π2 / 2) * ∫[0, ∞] (x(2x-1) * e(-x) / (Γ(x) * Γ(1 - x)) DX
a. To prove B(x+1, y) = x * B(x, y), proceed as follows.
Start with B(x+1, y) = [(x+1)! * y!] / ((x+y+2)!) (using the definition of B(x, y)).
Rewrite 1 / (x+1) to (x+y+2 - (y+1)) / (x+y+2) .
Using the formula above, express B(x+1, y) as (x+y+2) / (x+y+2) * [(x+1)! to rewrite. * y!] / ((x+y+2)!) - (y+1) / (x+y+2) * [(x+1)! * y!] / ((x+y+2) !).
Simplify the formula to (x+y+2) / (x+y+2) * B(x, y) - (y+1) / (x+y+2) * B(x, y) increase.
Simplify further to B(x, y) - (y+1) / (x+y+2) * B(x, y).
Note that B(x, y) can be expressed as (x / (x+y+1)) * B(x, y) .
Substitute this formula in the previous step to get,
x * B(x, y) - (y+1) / (x+y+2) * x * B(x, y).
x * B(x, y) - (y+1) / (x+y+2) * x * B(x, y)
= x * B(x, y)
You have now proved B(x+1, y) = x * B(x, y).
b. We wish to prove the identity Γ(2x) = ((2sin(πx))) * Γ(x) * Γ(x + 1/2).
Integrate ∫[0, ∞] (x(2x-1) * Start with dx.
Evaluating this integral using the permutation u = du is obtained.
Simplify the integral to (1/2) * Γ(x + 1/2).
Express sin(πx) as π / (Γ(x) * Γ(1 - x)).
Let the original integral be π * (2(2x-1) / π) * ∫[0, ∞] (x(2x-1) * e(-x) * (1/sin( πx) Rewrite.)) DX.
Substituting the equations,
The integral, π * (2(2x-1) / π) * ∫[0, ∞] (x(2x-1) *
We get * (π / (Γ(x) * Γ(1 - x)))) dx.

If a and b are two values, their ratio will be a:b,
Given that,
Kangaroo hopes 2 kilometers in 3 minutes.
To find the time taken by kangaroo to travel 5 kilometers,

2 kilometers = 3 minutes,
1 kilometer = 3/2 minutes
5 kilometer 15/2 minutes.
In 15/2 or 4.5 minutes, kangaroo will travel 5 kilometers.
The distance travelled by kangaroo in 2 minutes,
In 3 minutes = 2 kilometers covered
in 1 minute = 2/3 kilometers covered
in 2 minutes = 4/3 kilometers will be covered.

-3x^2+33=48x complete the square
Answers
The complete square form of - 3x² + 33 = 48x is [x + 8]² = 75
Completing the square:
To do this, we add and subtract a constant term to the quadratic expression to make it a perfect square.
In this case, we use the formula x² + 2bx + b² = (x + b)² to rewrite the quadratic expression as a perfect square trinomial, and then we solved for the variable by isolating the squared term and taking the square root.
Here we have
- 3x² + 33 = 48x
Keep 'x' terms on one side and constant terms sides on another side
=> - 3x² - 48x = - 33
Divide by - 3 on both sides
=> -3(x² + 4x)/3 = - 33/3
=> x² + 16x = 11
Take half of the 'x' term and square it and add on both sides
=> x² + 2(8x) (x) + (8)² = 11 + (8)²
Which is in the form of x² + 2bx + b² = (x + b)²
=> [x + 8]² = 75
Therefore,

225 cords
Answers
Answer:The new quantity supplied when the price is $348 per cord is 424.
Step-by-step explanation:
The new quantity supplied when the price is $348 per cord is 424.
What is the new quantity supplied?
The supply curve is a graph that shows the relationship between price and quantity supplied. The supply curve has a positive slope.
The slope of the supply curve is the ratio of the change in the value of price divided by the change in the value of the quantity supplied.
Slope = change in price / change in quantity supplied
0.75 = ($348 - $255) / change in quantity supplied
0.75 = $93 / change in quantity supplied
change in quantity supplied = 93 / 0.75 = 124
The new quantity supplied = 300 + 124 = 424

Given right triangle ABC, where side "c" is the hypotenuse, angle B measures 42 degrees, and side c measures 18 m, find the length of side b.
Answers
The length of side b of the given right angle triangle using law of sines is; b = 12.044 m
How to use the law of sines?The law of sines states that when we divide side "a" by the sine of angle A, it is equal to side "b" divided by the sine of angle B, and also equal to side "c" divided by the sine of angle C
Thus;
a/sin A = b/sin B = c/sinC
The parameters are;
B = 42°
c = 18m
Since c is the hypotenuse, it is the side that will be opposite the right angle and so;
C = 90°
Thus, using sine rule;
c/sinC = b/sin B
18/sin 90 = b/sin 42
b = (18 * sin 42)/1
b = 12.044 m

Answers
Answer:
c. Not significant at .055
Step-by-step explanation:
When a pair of dice is rolled, we have 6²=36 possible outcomes. Only 2 of these outcomes have a total score of 11:
When the first dice is 5 and the second is 6.When the first dice is 6 and the second is 5.Then, we can calculate the probability of getting 11 as the quotient between the successs outcomes and the total outcomes.
Then, the probability of getting 11 is:
\(P=\dfrac{X}{N}=\dfrac{2}{36}=0.055\)
This probability is not equal or less than 0.05, so it is not significant at 0.055.

Answers
The cost of each platter based on the information given will be $55.63.
How to calculate the cost?From the information given, it was stated that 259 students bought tickets and the total amount made was $2000. The committee spent the money they made to pay for music, decorations, and snacks. Tickets cost $4.50, and food.
Let the platter be represented by x.
Therefore, the equation to represent the situation will be:
(259 × $4.50) + (15 × x) = $2000
$1165.50 + 15x = 2000
15x = 2000 - 1165.50
15x = 834.50
x = $834.50/15
x = $55.63

Given SSxx is 950 and SSxy is 205.2. Calculate and interpret the value of r if the data
consist if 12 number of samples with y = 120 and Σy² = 2028
Answers
Step-by-step explanation:
To calculate the correlation coefficient (r) given SSxx, SSxy, and other information, we need to use the following formula:
r = √(SSxy / SSxx)
Given SSxx = 950 and SSxy = 205.2, we can substitute these values into the formula:
r = √(205.2 / 950)
Calculating the value:
r = √(0.216)
r ≈ 0.465
The correlation coefficient (r) is approximately 0.465.
Interpretation: The correlation coefficient measures the strength and direction of the linear relationship between two variables. In this case, the value of r = 0.465 indicates a positive linear relationship between the variables, but it's not a strong relationship. The closer the value of r is to 1 or -1, the stronger the relationship. Since r = 0.465 is relatively close to zero, it suggests a weak positive linear association between the variables being an analyzed.

The Pearson's correlation coefficient (r) based on given data is approximately 0.44, implying a moderate positive correlation.
Explanation:The formula for calculating Pearson's correlation coefficient (r) in this case is given as: r = SSxy / sqrt(SSxx * SSyy). However, we don't have the value for SSyy directly, but we can calculate it. We know that SSyy = Σy² -(Σy)² / n. Given that Σy² is 2028 and Σy is 120 and number of samples n is 12, we can calculate SSyy as: SSyy = 2028 - (120)² / 12 = 52. Now, substitute SSxx = 950, SSxy = 205.2 and SSyy = 52 in the formula to find r: r = 205.2 / sqrt(950 * 52), giving us an r-value of approximately 0.44. This value of r suggests a moderate positive correlation between the variables in the dataset.
