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.

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.

B = {d, o, I, e} I = {p, i, n, a, y} J = {p, i, n, o, y}
The solutions are;
1. U = {a, d, e, i, l, n, o, p, y}
2. E ∪ I = {a, d, e, i, l, n, o, p, y}
3. E ∩ I = { }
4. J' = {a, d, e, l}
5. I ∪ J = {p, i, n, a, o, y}

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

Based on the stemplot, which of the following is a correct comparison of the eastern and western states’ expenditures?
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
