Please Help, Consider the following sets in the universal set U, which is the set of all elements of the three given sets below. List the elements of the sets being described.
B = {d, o, I, e} I = {p, i, n, a, y} J = {p, i, n, o, y}
Answers
The results of the operations between the sets are given as follows:
1. U = {a, d, e, i, l, o, n, p, y}
2. E ∪ I = {d, o, l, e, p, i, n, a, y}.
3. E ∩ I = ∅.
4. J' = {d, a, l, e}
5. I ∪ J = {p, i, n, a, y, o}
6. (J ∩ I) ∪ E = {p,i,n,y,d,o,l,e}
7. E = {p, i, n, a, y}
8. I' ∪ J = {p, i, n, y, d, o, l, e}
9. (E ∪ I) ∩ (I ∪ J) = {p, i, n, a, y, o}
10. (J ∪ I)' = {d, l, e}
What is the universal set?The universal set is the set that contains all elements that belong to at least one of the sets E, I and J, hence:
U = {a, d, e, i, l, o, n, p, y}
What is the union operation?The union operation between two sets is the set of elements that belong to at least one of the sets.
Hence, in item 2, we have that:
E ∪ I = {d, o, l, e, p, i, n, a, y}
In item 5, we have that:
I ∪ J = {p, i, n, a, y, o}
What is the negation operation?The negation operation of a set X is the set that contains all elements that belong to the universe U but do not belong to X.
Hence, for item 4, we have that:
J' = {d, a, l, e}
For item 7, we have that:
E = {p, i, n, a, y}
Item 8 involves a negation then a union, hence:
I' = {d,o,l,e}
I' ∪ J = {p, i, n, y, d, o, l, e}
Item 10 involves an union then a negation, just different precedence of 8, hence:
I ∪ J = J ∪ I = {p, i, n, a, y, o}
(J ∪ I)' = {d, l, e}
What is the intersection operation?The union operation between two sets is the set of elements that belong to both of the sets.
Hence, in item 3, we have that:
E ∩ I = ∅ (no element belongs to both sets).
For item 6, we have an intersection then an union, hence:
J ∩ I = {p,i,n,y}
(J ∩ I) ∪ E = {p,i,n,y,d,o,l,e}
For item 9, we have the intersection of two unions, hence:
E ∪ I = {d, o, l, e, p, i, n, a, y}
I ∪ J = {p, i, n, a, y, o}
(E ∪ I) ∩ (I ∪ J) = {p, i, n, a, y, o}

Carolyn needs to figure out the missing properties used to simplify the expression below
Answers
The properties used in the the simplification of the expression is:
step 1: Inverse multiplication property
step 2: Commutative property
step 3: Associative property
step 4: Commutative property
step 5: Identity property
Given the expression is:
1 ÷ 2/3 × (₋5) × 3 ÷ (₋1/4)
step 1: 1 × 3/2 × (₋5) × 3 × (₋4)
Inverse multiplication property is applied.
The reciprocal of a particular integer is referred to as the multiplicative inverse. It is employed to make mathematical expressions simpler. The word "inverse" denotes an opposing or opposed action, arrangement, position, or direction. A number becomes 1 when it is multiplied by its multiplicative inverse.
step 2: 1 × (₋4) × 3/2 × (₋5) × 3
Commutative property is applied.
Mathematical addition and multiplication operations are covered under the commutative property. In other words, adding or multiplying two integers does not change the outcome if the order or location of the numbers is changed.
step 3: 1 × [(₋4) × 3/2] × (₋5) × 3
Associative property is applied.
According to the associative feature of multiplication, the outcome of a multiplication problem is unaffected by the arrangement of the numbers in the problem's constituent parts.
step 4: 1 ×[-6] × (₋5) × 3
commutative property is applied.
step 5: (-6) × (₋5) × 3
Identity property is applied.
Multiplying 1 by any number yields the number itself, according to the Multiplicative Identity Property, commonly known as the Identity Property of Multiplication. This is because any time a number is multiplied by 1, it retains its identity and does not change.
Hence we have applied the above mentioned properties of multiplication.

The total weight of the two animals is 1.2 x 10^5 lbs
How to determine the total weight of the two animals?The given parameters are
Animal 1 = 5.36 x 104 lbs.
Animal 2 = 6.2 x 104 lbs
Rewrite the parameters properly
Animal 1 = 5.36 x 10^4 lbs.
Animal 2 = 6.2 x 10^4 lbs
The total weight of the two animals is calculated as
Total weight = Animal 1 + Animal 2
This gives
Total weight = 5.36 x 10^4 lbs + 6.2 x 10^4 lbs.
Factor out 10^4 lbs
Total weight = (5.36 + 6.2) x 10^4 lbs.
Evaluate the sum
Total weight = 11.56 x 10^4 lbs.
Rewrite as
Total weight = 1.156 x 10^5 lbs.
Approximate
Total weight = 1.2 x 10^5 lbs.
Hence, the total weight of the two animals is 1.2 x 10^5 lbs

Some of the Translation are,
A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection. A figure is said to reflect the other figure, and then every point in a figure is equidistant from each corresponding point in another figure.
Rotation means the circular movement of an object around a centre. It is possible to rotate different shapes by an angle around the centre point.
Translation means the displacement of a figure or a shape from one place to another. In translation, a figure can move upward, downward, right, left or anywhere in the coordinate system.

A formal logical framework used to infer a conclusion from a series of premises is referred to as a syllogism, also known as a rule of inference.
The law of syllogism in conditional statement is given as:
if p then r and if r then q , then we can state that if p then q , where p , q, and r are statements.
Now in the given conditional statements we can write it as:
let p = You go camping
r = you will need a flashlight
q = you will need extra batteries.
