Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Fifteen students in a class received the following scores on their last test:
15, 62, 65, 65, 71, 73, 74, 75, 75, 81, 83, 84, 88, 91, 96, 99
Which of these numbers could be considered an "outlier"?
Answers
An outlier is a data point that lies outside the overall pattern in a distribution.
__________________________________________________________
Here, we have 15, 62, 65, 65, 71, 73, 74, 75, 75, 81, 83, 84, 88, 91, 96, 99.
The outlier here would be 15 because compared to the other numbers 15 is not as close to 60-90 as the others are.

An outlier is a data value that is the smallest/largest in the entire set and that is alot smaller/larger than the other values in the set. It can be considered the odd one out.
Here we notice that all the scores are clumped together (from 62 to 99) but one of them is further away than the other ones. That number is 15.
Hence, 15 is the outlier.PLEASE HELP if can

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
Answers
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Step-by-step explanation:
Given that n(U) =50, n(P) = 28, n(Q) = 35 and n(P'nQ') =x, Express (P'nQ), (PnQ),
and n(PnQ') in terms of x. Find the greatest and the smallest possible values of x.
Answers
Given the following information:
\(\displaystyle\sf n(U) = 50\)
\(\displaystyle\sf n(P) = 28\)
\(\displaystyle\sf n(Q) = 35\)
\(\displaystyle\sf n(P'\cap Q') = x\)
Let's express the requested values in terms of x:
1. \(\displaystyle\sf P'\cap Q\):
Using the principle of complements, we know that \(\displaystyle\sf P'\cap Q = U \setminus (P \cup Q) = U - (P \cup Q)\).
Since the universal set U has 50 elements, and we are given that \(\displaystyle\sf n(P) = 28\) and \(\displaystyle\sf n(Q) = 35\), we can calculate the value of \(\displaystyle\sf n(P \cup Q)\):
\(\displaystyle\sf n(P \cup Q) = n(P) + n(Q) - n(P \cap Q)\).
Since we don't have the value of \(\displaystyle\sf n(P \cap Q)\), we cannot calculate the exact value of \(\displaystyle\sf n(P \cup Q)\). Therefore, we cannot express \(\displaystyle\sf P'\cap Q\) in terms of x.
2. \(\displaystyle\sf P \cap Q\):
Using the same principle of complements, we know that \(\displaystyle\sf P \cap Q = U \setminus (P' \cup Q') = U - (P' \cup Q')\).
Similarly, we cannot calculate the exact value of \(\displaystyle\sf n(P' \cup Q')\) since we don't know \(\displaystyle\sf x\). Thus, we cannot express \(\displaystyle\sf P \cap Q\) in terms of x.
3. \(\displaystyle\sf n(P \cap Q')\):
Using De Morgan's laws, we know that \(\displaystyle\sf n(P \cap Q') = n(P) - n(P \cap Q)\).
Since we are given that \(\displaystyle\sf n(P) = 28\), we need to calculate \(\displaystyle\sf n(P \cap Q)\). Unfortunately, we don't have enough information to find the exact value of \(\displaystyle\sf n(P \cap Q)\) in terms of x. Therefore, we cannot express \(\displaystyle\sf n(P \cap Q')\) in terms of x.
Regarding the greatest and smallest possible values of x, without additional information or constraints, we cannot determine those values. We would need more details or conditions related to the intersection of sets P and Q or other relevant factors to determine the range or limitations of x.
This is a question related to set theory, a branch of mathematics that deals with the properties of well-defined collections of objects1. Here are some formulas that might help you solve the question2:
The complement of a set A is denoted by A’ and it contains all the elements that are not in A.
The union of two sets A and B is denoted by A ∪ B and it contains all the elements that are in either A or B or both.
The intersection of two sets A and B is denoted by A ∩ B and it contains all the elements that are in both A and B.
The difference of two sets A and B is denoted by A - B and it contains all the elements that are in A but not in B.
The cardinality of a set A is denoted by n(A) and it represents the number of elements in A.
Using these formulas, we can express the sets (P’nQ), (PnQ), and n(PnQ’) in terms of x as follows:
(P’nQ) = (P ∪ Q)’ = U - (P ∪ Q) = U - P - Q + P ∩ Q
(PnQ) = P ∩ Q
n(PnQ’) = n(P) + n(Q’) - n(P ∩ Q’) = n(P) + n(U) - n(Q) - n(P ∩ Q)
To find the greatest and smallest possible values of x, we need to use the following formula2:
n(A ∪ B) = n(A) + n(B) - n(A ∩ B)
Applying this formula to P and Q, we get:
n(P ∪ Q) = n(P) + n(Q) - n(P ∩ Q)
50 - x = 28 + 35 - n(P ∩ Q)
x + n(P ∩ Q) = 13
Since x and n(P ∩ Q) are both non-negative integers, the greatest possible value of x is 13 when n(P ∩ Q) is 0, and the smallest possible value of x is 0 when n(P ∩ Q) is 13.
I hope this helps you understand the question better.

Answers
Answer:
B: 1/36 EQUIVALENT
D: NONE OF THE ABOVE
Step-by-step explanation:
Rolling a single 3 is 1/6, rolling another 3 is 1/6 again. SO you multiply the probabilities to find the probability of rolling double 3s. 1/6 × 1/6 = 1/36 so B.
These are all the ways you could roll a sum of 7:
1, 6
2, 5
3, 4
4, 3
5, 2
6, 1
This is 6 of the 36 possible rolls so there is a 1/6 chance of rolling a sum of 7, SO D.

Answer: Ok, fast. Here we go: Basically the number sequence increases by 3 every number. 7+3=10 10+3=13. Etc, etc.
Step-by-step explanation:
So just go from 19 (which is the 5th term) and count up.
19+3=22(6th term) 22+3=25(7th term) 25+3=28(8th term) 28+3=31(9th Term) 31+3=34(10th term)
34 is your answer.
a: We can quickly find the answer by multiplying 3 by 5, then by adding the quantity of the numbers to 19.
\(5(3) + 19\)
15 + 19 = 34
Therefore, the 10th term in this number sequence is 34.
b: n represents the numbered term of the number sequence.
3 can represent x in the expression we make.
\(3x = n\)
Therefore, a possible expression for this number sequence is 3x = n.

What is the radius of J. A. 24.8
B. 6.2
C. 10.8
D. 12.4
Answers
Answer:
12.4 units
Step-by-step explanation:
The diameter of circle J is represented by KN. Half of KN is KJ and JN which means these represent the radius. Since JN equals 12.4 and JN is the the radius, then the radius of circle J is 12.4 units which is answer choice D.
The radius of the given circle is 6.2 unit. So option B is correct.
What is the radius?A line segment from a circle's or sphere's center to its perimeter or boundary is known as the radius in geometry. It is a crucial component of spheres and circles and is frequently abbreviated as "r". When discussing multiple radiuses at once, the plural form of radius is "radii". The diameter of a circle or sphere is the longest line segment connecting all points on the opposite side of the centre, and the radius is equal to half of the diameter in length. It can be written as d/2, where d is the circle's or sphere's diameter. Look at the illustration of a circle below that depicts the connection between radius and diameter.
Given that,
A circle,
which contains diameter KN of length 12.4 unit
and chord 10.8 unit.
The radius = ?
It is known that, the length of the radius is half of the diameter of the circle,
R = D/2
= 12.4/2
= 6.2
Therefore, the length of the radius is 6.2 unit.
