find the midpoint of points A(8,10)and B(0,5) graphically
Answer:
Step-by-step explanation:
Midpoint coordinates(x, y) of 2 points (x1, y1) and (x2, y2) are given by
x = (x1 + x2)/2
y = (y1 + y2)/2
So in this situation
x = (8 + 0)/2 = 8/2 = 4
y = (10 + 5)/2 = 15/2 = 7.5
Midpoint is at (4, 7.5)

show that theorem 2.6, the additive law of probability, holds for conditional probabilities. that is, if a, b, and c are events such that p(c) > 0, prove that p(a ∪ b|c)
P(AUB|C)=P(A|C) + P(B|C) - P(AnB|C) is the correct answer.
From distributive law we have,
P((AUB)nC)=P(AnC) + P(BnC)-P(AnBnC)
Dividing both sides by P(C)
P((AUB)nC)/P(C)=P(AnC)/P(C) + P(BnC)/P(C) - P(AnBnC)/P(C)
P(AUB|C)=P(A|C) + P(B|C) - P(AnB|C)

Kym is renovating the first floor of her house. She bought 750 square feet of laminate flooring and 525 square
feet of carpet and paid $2717.25. She went back to the store and bought an additional 100 square feet of
laminate flooring and 75 square feet of carpet and paid $374.75. Find the cost per square foot of each type of
flooring. equation
Using simultaneous equations in two variables we get that the cost of laminate is $ 0.65 per sq. feet and the cost of carpet is $ 4.12 per sq. feet.
Equations in algebra that involve two or more variables simultaneously, such as x and y, are referred to as simultaneous equations. The equations are referred to as simultaneous equations since they are solved simultaneously. There are countless possible solutions to just these equations.
A set of finite equations for which common solutions are sought makes up a system of equations, often known as an equation system.
Let the cost per sq feet of laminate be x and the cost per sq feet of carpet be y.
Now it is given that the cost of 750 sq feet of laminate and 525 square foot of carpet is $2717.25
∴ 750x+525y=2717.25
Again the cost of 100 sq feet of laminate and 75 square foot of carpet is $374.75
∴ 100x + 75 y = 374.15
Now we solve the pair of simultaneous equations to find the value of x and y:
Multiplying the second equation by 7 and subtracting from the first we get:
750x + 525y = 2717.25
600x + 575 y = 2619.05
150x = 98.20
or, x = 0.654...
Substituting this value in the first equation we get:
y= 4.115...
Therefore the solution of the simultaneous equation is:
x = $ 0.65 and y = $ 4.12
Therefore the cost of laminate is $ 0.65 per sq. feet and the cost of carpet is $ 4.12 per sq. feet.

What is Union of the set?
Union of two or more set is the set containing all the elements of the given set.
Here, U is the universal set, which is the set of all elements of the three given sets.
And, Three sets are;
⇒ E = {d, o, I, e}, I = {p, i, n, a, y}, J = {p, i, n, o, y}
Now, We find the universal set as;
1. U = {{a, d, e, i, l, n, o, p, y}
2. And, E ∪ I = {d, o, I, e} ∪ {p, i, n, a, y}
= {a, d, e, i, l, n, o, p, y}
Hence, E ∪ I = {a, d, e, i, l, n, o, p, y}
3. E ∩ I = {d, o, I, e} ∩ {p, i, n, a, y}
Since, It cannot contain any common elements.
So, Intersection of E and I is null set.
Hence, E ∩ I = { }
4. Since, J' = U - J
J' = {a, d, e, i, l, n, o, p, y} - {p, i, n, o, y}
J' = {a, d, e, l}
Hence, J' = {a, d, e, l}
5. I ∪ J = {p, i, n, a, y} ∪ {p, i, n, o, y}
= {p, i, n, a, o, y}
Hence, I ∪ J = {p, i, n, a, o, y}
6. ( J ∩ I ) ∪ E = ({p, i, n, o, y} ∩ {p, i, n, a, y}) ∪ {d, o, I, e}
= {p, i, n, y} ∪ {d, o, I, e}
= {d, o, l, e, p, i, n, y}
Hence, ( J ∩ I ) ∪ E = {d, o, l, e, p, i, n, y}
7. E' = U - E
= {a, d, e, i, l, n, o, p, y} - {d, o, I, e}

Hence, E' = {a, i, n, p, y}
8. I' ∪ J = (U - I) ∪ J
= ( {a, d, e, i, l, n, o, p, y} - {p, i, n, a, y}) ∪ {p, i, n, o, y}
= {d, e, l, o} ∪ {p, i, n, o, y}
= {d, e, l, o, p, i, n, y}
Hence, I' ∪ J = {d, e, l, o, p, i, n, y}

= { } ∩ {p, i, n, a, o, y}
= { }
Hence, (E ∩ I) ∩ (I ∪ J) = { }

Going by the stemplot, a correct comparison to make between eastern and western states’ expenditures is The eastern states have, on average, a higher per-pupil expenditure than the western states.
How to read a stemplot?Reading a stemplot requires looking at the stem first which is the number in the middle. Then combine this with the leaf to find the actual number. For instance, a stem of 7 and a leaf of 6 in the attached photo is $76,000.
From the attached photo, we see that the Eastern states have more numbers of per-pupil expenditure which means that on average, they have a higher per-pupil expenditure than the western states.
Options for this question are:
The western states exhibit more variability in their expenditures than the eastern states. The eastern states have, on average, a higher per-pupil expenditure than the western states. The distribution of per-pupil expenditures in the eastern states is more symmetric than the distribution of the western states. The distribution of the western states' per-pupil expenditure is skewed left, while the distribution of the eastern states' per-pupil expenditure is skewed right. Valid conclusions comparing the distributions cannot be made, since there is a different number of states in each group.Find out more on stemplots at https://brainly.com/question/22400218

For each annual rate of change, find the corresponding growth or decay factor. +0.1%
The growth factor for the annual rate of change +0.1 % is 1.001.
A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.
With the function displayed to the right, you may represent exponential growth or decay.
A(x) = a( 1 + r)ˣ
Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.
Now, we have the annual rate of change as:
r = + 0.1% = + 0.1 / 100 = + 0.001
From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.
So, let B = 1 + r
B = 1 + r
B = 1 + (+0.001)
B = 1.001
Now, the value of B is greater than 1 therefore, the corresponding growth factor is 1.001.

The number 102 in the sequence will be closest to 100.
A sequence in which each next term gets increased or decreased from the preceding by a constant value is called an arithmetic progression.
The difference of any two consecutive terms in an arithmetic progression is called the common difference of the AP (arithmetic progression).
Here each terms increases by 8. So, the common difference d is 8.
The first term is given to be 38.
So our sequence will be,
38, 46, 54, 62,...
nth term in an AP can be calculated by using the formula,
aₙ = a₁ + (n-1)d
To find the term nearest to 100,
100 = 32 + (n-1)8
68/8 = (n-1)
9.5 = n
But the value of n can not be a non-integer,
So the term nearest to 100 will be 9th or 10th term.
a₉ = a₁ + (9-1)d
a₉ = 8 + (8 x 8)
a₉ = 94
and,
a₁₀ = a₁ + (10-1)d
a₁₀ = 8 + (9 x 8)
a₁₀ = 102.
We can see,
a₁₀ = 102 is closest to 100.
Hence, 10th term is closest to 100.

Now, we will calculate the [tex]\sum_{i=1}^{n}(x_{i}-\bar{X})(y_{i}-\bar{Y})[/tex] and [tex]\sum_{i=1}^{n}(x_{i}-\bar{X})^{2}[/tex], we get
[tex]\sum_{i=1}^{n}(x_{i}-\bar{X})^{2}=28[/tex]
and [tex]\sum_{i=1}^{n}(x_{i}-\bar{X})(y_{i}-\bar{Y})=55.5[/tex]
Calculate the slope.
[tex]\begin{aligned}m&=\frac{\sum_{i=1}^{n}(x_{i}-\bar{X})(y_{i}-\bar{Y})}{\sum_{i=1}^{n}(x_{i}-\bar{X})}\\ &=\frac{55.5}{28}\\ &=1.9821\end[/tex]
Calculate the y -intercept.
Use the formula to compute the y -intercept.
[tex]\begin{aligned}b&=\bar{Y}-m\bar{X}\\ &=8.14-(1.9821\times3)\\ &=8.14-5.9463\\ &=2.1937\end[/tex]
Use the slope and y -intercept to form the equation of the line of best fit.
The slope of the line is 1.9821 and the y -intercept is 2.1937 .
Therefore, the equation is y=1.9821x+2.1937 .
Draw the line on the scatter plot.
Hence, the scatter plot is shown in attached image and the line of best fit for given data set (0,2),(1,4),(2,6.5),(3,8.5),(4,10),(5,12),(6,14) is y=1.9821x+2.1937.

someone please help me i’ve been stuck on this for the longest
Answer:
-3/2
Step-by-step explanation:
Slope:
Rise: The difference between the y -coordinates of the two points is called the rise.
Run: The difference between the x-coordinates of the same two points is called the run.
First plot two points on the line.
(0, 6 ) and (4 , 0)
Rise = 6 - 0 = 6
Run = 0 - 4 = -4
[tex]\sf \boxed{Slope = \dfrac{Rise}{Run}}[/tex]
[tex]\sf =\dfrac{6}{-4}\\\\=\dfrac{-3}{2}[/tex]
44. The Loveland town council wants to build a bandstand. Architects were asked to submit plans. In the plan shown, the floor has the shape of a regular octagon. a) What is the area of the floor of the bandstand in this plan? 20 ft b) What would the dimensions be of a square bandstand with the same area as the octagon above? c) Which one has the largest perimeter?
Area of the floor of the bandstand in regular octagon is 1931.2 ft²
dimensions of a square bandstand with the same area as the octagon is 43.94 ft
square bandstand has largest perimeter.
floor has the shape of a regular octagon
Area of a regular octagon = 2a²(1+[tex]\sqrt{2}[/tex])
a = length of the side of the octagon
here a = 20 ft
Area = 2a²(1+[tex]\sqrt{2}[/tex]) = 2(20)(20)(1+[tex]\sqrt{2}[/tex])
= 800(1+1.414)
= 800(2.414)
= 1931.2 ft²
square bandstand with the same area as the octagon
Area of square = b²
b = length of the side of the square
1931.2 = b²
b = 43.94 ft
Perimeter of regular octagon = 8a
= 8(20)
= 160ft
Perimeter of Square = 4b
= 4(43.94)
= 175.78ft
area of the floor of the bandstand in regular octagon is 1931.2 ft²
dimensions of a square bandstand with the same area as the octagon is 43.94 ft
square bandstand has largest perimeter.
