Consider U = {x\x is a positive integer greater than 1}.
Which is an empty set?
{xx € U and 2x is prime}
{xlx EU and 2x is prime}
{XX € U and 1/2x can be written as a fraction}
{x|x € U and 2x can be written as a fraction}
Considering U = {x l x is a positive integer greater than 1} the empty set will be,
⇒ { X ∈ U and 2x is prime}
What are prime numbers?Prime numbers refers to a whole number more than 1 whose only factors are 1 and itself.
Now, A whole number that may be split evenly into another number by multiplication is referred to as a factor.
2, 3, 5, 7, 11, 13, 17, 19, 23 and 29 are the first few prime numbers.
Here, The number 2 is the only prime even number and hence no other prime number will be fall as an even number or a product from multiplication by 2.
Hence, Considering U = {x l x is a positive integer greater than 1} the empty set will be,
⇒ { X ∈ U and 2x is prime}

Solve the system of equations.
y= 2x + 4
y = x2 + x - 2
A. (-2, 0) and (3, 10)
B. (2,0) and (-3,-10)
C. (-3,-10) and (-2,0)
D. (-3, 10) and (2,0)
Answer:
A
Step-by-step explanation:
Given the 2 equations
y = 2x + 4 → (1)
y = x² + x - 2 → (2)
Substitute y = x² + x - 2 into (1)
x² + x - 2 = 2x + 4 ( subtract 2x + 4 from both sides )
x² - x - 6 = 0 ← in standard form
(x - 3)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x + 2 = 0 ⇒ x = - 2
Substitute these values into (1) for corresponding values of y
x = 3 : y = 2(3) + 4 = 6 + 4 = 10 ⇒ (3, 10 )
x = - 2 : y = 2(- 2) + 4 = - 4 + 4 = 0 ⇒ (- 2, 0 )

M is the centroid of the triangle.
CM=7, PM=10, & BQ=18
BM=[? ]
Answer:
The length of the BM is 6 unit.
Step-by-step explanation:
Given : M is the centroid of the triangle. CM=7, PM=10, & BQ=18
To find : The value of BM ?
Solution :
Refer the attached figure below.
The centroid of a triangle is the point of intersection of its medians.
M is the centroid and the centroid divide the line in 1:2 ratio.
So, M divide BQ in 1:2 ratio and the total length of BQ is 18.
BM is one third of 18.

During a solo competition for playing the flute, Sandra was given the following scores by four of the five judges:
6, 8, 9, and 8. What score would the fifth judge need to give her so that her average score from the five judges
was 8.0?
Answer: she needs a 9 from the fifth judge
Step-by-step explanation: so you have 5 judges and to get a perfect score you need 8. when you multiply the amount of judges by the score of 8 you get 40 witch is 100%, and when you add 6+8+9+8 you get 31 so there is 9 missing to get 40 so the answer is 9.
In triangle ABC, a = 4, b = 6, and cos C = − 1/4. What is the length of side c?
(1)8
(2)2√7
(3)2√10
(4)4
The length of side c would be 8.
Step-by-step explanation:
Given that,
a = 4
b = 6
cosC = -1/4
If we are given two sides and angle, the law of Cosines can be used to find the third side:
[tex]c^{2} = a^{2} + b^{2} - 2ab (cos(c))[/tex]
By inserting the values in the formula, we get
[tex]c^{2} = 4^{2} + 6^{2} - 2.4.6 (-\frac{1}{4} )[/tex]
[tex]c^{2} = 16 + 36 + 12[/tex]
[tex]c^{2} = 64[/tex]
[tex]\sqrt{c^{2} } = \sqrt{64}[/tex]
c = 8.
Therefore, the length of side c would be 8.
The length of side [tex]\( c \)[/tex] is 8. The option (1) is correct.
To find the length of side [tex]\( c \)[/tex] in triangle ABC given [tex]\( a = 4 \), \( b = 6 \)[/tex], and [tex]\( \cos C = -\frac{1}{4} \),[/tex] we use the cosine rule:
[tex]\[ c^2 = a^2 + b^2 - 2ab \cos C \][/tex]
Substitute the given values:
[tex]\[ c^2 = 4^2 + 6^2 - 2 \cdot 4 \cdot 6 \cdot \left(-\frac{1}{4}\right) \][/tex]
[tex]\[ c^2 = 16 + 36 + 12 \][/tex]
[tex]\[ c^2 = 64 \][/tex]
Now, take the square root of both sides to find [tex]\( c \):[/tex]
[tex]\[ c = \sqrt{64} \][/tex]
[tex]\[ c = 8 \][/tex]
Therefore, the length of side [tex]\( c \)[/tex] is 8.

On the last day of April 2009, the price of a share of stock in a major entertainment corporation was $5.36. Over the next 4 years, the annual growth rate was 4.15%. The growth in the price of this stock can be modeled by the function where P represents the price, in dollars, and t represents the number of years since the last day in April 2009. Which function can be used to represent the price of a share of stock in this entertainment corporation on the last day in June 2011?
Answer:
Hence After 2 years from 2009 to 2011 THe price for share of stock will be 5.8141 $
Step-by-step explanation:
Given:
Initial price=$5.36
Rate=4.15 %
To Find:
Function which represents the growth price for stock market?
Solution:
As the function is growing one and with same rate and depends upon the time period ,
So the exponential function as
[tex]P=A(1+R)^t[/tex] will the required function ,
So P will be price of stock at t time period with R as rate for function.
A be the previous year price
From 2009 to 2013 rate is 4.15 %
we have to find price after 2 years
So t=2 , A at 2009 =5.36$
So P at 2011 will be given by,
[tex]P=A(1+R)^t[/tex]
[tex]P=5.36(1+0.0415)^2[/tex]
[tex]P=5.36(1.0415)^2[/tex]
[tex]P=5.8141 $[/tex]

Step-by-step explanation:
to find the terms, in a row, replace n with 1
nth = 1^2 -3 -2 is the answer (1^2) is 1 -3 = -2
then replace the n with 2, 3, 4 etc till you have your sequence
nth = 2^2 -3 1 is the answer (2^2) is 4 -3 = 1
nth = 3^2 -3 6 is the answer (3^2) is 9-3 = 6
nth = 4^2 -3 13 is the answer (4^2) is 16-3 = 13
nth = 5^2 -3 22 is the answer (5^2) is 25-3 = 22
etc to 10
nth = 10^2 -3 97 is the answer (10^2) is 100 - 3 = 97
sequence is -2, 1, 6, 13, 22, . . . . 97
Three students take equivalent stress tests. Which is the highest relative score (meaning which
has the largest z score value)?
a. A score of 144 on a test with a mean of 128 and a standard deviation of 34
b. A score of 90 on a test with a mean of 86 and a standard deviation of 18
c. A score of 18 on a test with a mean of 15 and a standard deviation of 5
B is the correct answer with the explanation of a score of 90 on a test with a mean of 86 and a standard deviation of 18.
The highest relative score is of the student with a score of 18 on a test with a mean of 15 and a standard deviation of 5
What is z-score?Z-score is a statistical measurement that describes a value's relationship to the mean of a group of values.
Given that, three students take equivalent stress tests, we need to calculate the highest relative score among them,
Z-score = X-μ / σ,
X = observed value, μ = mean and σ = standard deviation
a) A score of 144 on a test with a mean of 128 and a standard deviation of 34 :-
Z-score = X-μ / σ
Z-score = 144-128 / 34 = 0.47
b) A score of 90 on a test with a mean of 86 and a standard deviation of 18 :-
Z-score = X-μ / σ
Z-score = 90-86 / 18 = 0.22
c) A score of 18 on a test with a mean of 15 and a standard deviation of 5 :-
Z-score = X-μ / σ
Z-score = 18-15 / 5 = 0.6
Hence, the highest relative score is of the student with a score of 18 on a test with a mean of 15 and a standard deviation of 5

What is the graph to the piecewise defined function g(x) = { x+4, -5<=x<=-1
2-x, -1<=x<=5?
Answer:
third graph, see attached in case the order changes
Step-by-step explanation:
g(x) = { x+4, -5<=x<=-1
2-x, -1<=x<=5
The graph will change at -1, so we can eliminate the first graph
It changes completely so we can eliminate the second graph
From -5 to -1 the slope is positive 1 so it will increase from left to right
The last graph decreases, so it has a negative slope at -5. We can eliminate the last graph
That leaves us the third graph
g(x) = x+4, -5《x《-1
At x = -5, g(x) = -1
At x = -1, g(x) = 3
g(x) = 2-x, -1《x《5
At x = -1, g(x) = 3
At x = 5, g(x) = -3

True or false: opposite angles of a square are supplementary angles
Answer:
True
Step-by-step explanation:
Supplementary angles are those that sum up to 180 degrees. A square is a polygon with all its angles measuring 90 degrees. This means that opposite angles are both 90 degrees. And, since 90 + 90 = 180, that means that a square's opposite angles are supplementary.
Hope this helps!
Answer:
True
Step-by-step explanation:
Supplementary angles add up to 180
All angles in a square are 90.
Opposite angles add up to 180°
There are a total of 15 dimes and quarters in a covered cup. The value of all 15 coins totals 2.85
Answer:
There are 6 dimes and 9 quarters.
Step-by-step explanation:
Represent the number of dimes and the number of quarters by d and q.
Then d + q = 15, or q = 15 - d.
Also, ($0.25)q + ($0.10)d = $2.85, or 5q + 2d = 57.
Substituding 15 - d for q, we get 5(15 - d) + 2d = 57, or
75 - 5d + 2d = 57, or
75 - 3d = 57, or
3d = 18. Thus, there are 6 dimes. Since q = 15 - d, q = 15 - 6 = 9.
There are 6 dimes and 9 quarters.
The number of dimes and quarters totaling $2.85 are 6 dimes and 9 quarters.
To solve this, we can set up two equations based on the number of coins and their total value.
Let's denote the number of dimes as d and the number of quarters as q. The value of a dime is $0.10, and the value of a quarter is $0.25. We know there are 15 coins in total, which gives us the first equation:
d + q = 15
The second equation is based on the total value of the coins:
0.10d + 0.25q = 2.85
To solve the system of equations, we can use substitution or elimination. Multiplying the second equation by 10 gives us:
d + 2.5q = 28.5
Subtracting the first equation from this results in:
1.5q = 13.5
Dividing by 1.5 gives us the number of quarters:
q = 9
Substituting q = 9 into the first equation gives us the number of dimes:
d + 9 = 15
d = 6
Therefore, there are 6 dimes and 9 quarters in the cup.
In ΔFGH, the measure of ∠H=90°, GF = 41, HG = 40, and FH = 9. What ratio represents the cosine of ∠F?
