24
Answers
Answer:
Option D.
The discriminat is equal to 24 which
Step-by-step explanation:
The quadratic equation is
-2x² + 3 = 0
Discriminat in quadratic equation tells us the number of solution a quadratic equation has.
For example, the quadratic equation
Ax² + bx + c = 0 will have a discriminat of b² - 4ac.
b² - 4ac is equal to the value of the discriminat and equal to the number of solutions the quadratic equation has.
In our question, we have -2x² + 3 = 0
A = -2
B = 0
C = 3
b² - 4ac = 0
Substitute the values into the above equation.
0² - 4(-2 ×3) = 0
0 + -4 × -6 = 0
24 = 0
The discriminat of the equation is 24

Which of the following represents the symmetric property of congruence? Question 7 options: A) If ≅ and ≅ , then ≅ B) If ≅ , then ≅ C) ≅ D) If ≅ , then ≅
Answers
Answer:
The symmetric property of congruence is:
If ∠A ≅ ∠B, then ∠B ≅ ∠A.
If, AB ≅ CB, then CB ≅ AB.
Step-by-step explanation:
Two triangles are said to be congruent if they have the same three sides and the same three angles, not necessarily the same sides or the same angles are equal.
The properties of congruence are:
Reflexive property:For all angles A, ∠A ≅ ∠A. That is, all angles are congruent to themselves.
If AB is side of a triangle then, AB ≅ AB.
Symmetric Property:For any angles A and B if, ∠A ≅ ∠B, then ∠B ≅ ∠A.
For sides AB and CB of a triangle if, AB ≅ CB, then CB ≅ AB.
Transitive property:For any angles A, B and C if, ∠A ≅ ∠B, and ∠B ≅ ∠C then ∠A ≅ ∠C.
For sides AB, CB and CA of a triangle if, AB ≅ CB, and CB ≅ CA, then AB ≅ CA.
Thus, the symmetric property of congruence is:
If ∠A ≅ ∠B, then ∠B ≅ ∠A.
If, AB ≅ CB, then CB ≅ AB.

You are also given that the sum of any three consecutive terms in the sequence is the same and that the sum of the thirteen terms is 217. What is the sequence? Someone pllzzzz help
Answers
Answer:
Step-by-step explanation:
Let the sequence as :
[tex]T_1, T_2, T_3, 17, T_5, T_6,......T_{13}[/tex]
I put 17 there as [tex]T_4[/tex] because I want 3 consecutive elements. Let A is the sum of them.
[tex]T_1+T_2+T_3 = A[/tex]
17
[tex]T_5+T_6+T_7 = A[/tex]
[tex]T_8+T_9+T_{10} = A[/tex]
[tex]T_{11}+T_{12}+T_{13}=A[/tex]
[tex]\sum T_i + 17 = 217 = 4A + 17[/tex]
Hence A = 50
Then, back to the condition
[tex]T_4+ T_5 + T_6 = A = 50[/tex]
[tex]T_5+T_6+T_7 = A = 50[/tex]
Subtract them, we get
[tex]T_4 - T_7 = 0[/tex]
That gives you
[tex]T_4 = T_7 = 17[/tex]

A voter polling research group determined that 30% of the voters in a county would vote for the democratic candidate with a ±4% margin of error. If they anticipate only 12,000 people will turn out to vote in this election, which would represent the lowest possible number of voters for the democratic candidate.
Answers
Answer:
Minimum number of voters for the democratic candidate would be 3120 voters.
Step-by-step explanation:
Total number of people turning out to vote = 12,000
Percentage of votes a democratic would get = 30%
Which means that it is expected that a democratic candidate will get: 30/100 · 12,000 = 3600 votes
However, the polling may have an error of +4% to -4%
Which means that the votes a democratic candidate will get will range from 30%+4% = 34% to 30%-4%= 26% of the total people who turn out to vote
Minimum number of voters can be determined by taking 26% of the total people who turn out to vote:
Minimum number of votes = 26/100 · 12,000 = 3120

A pom-pom manufacturer makes each of its pom-poms with 35% white strands (w), 25% blue strands (b), and 40% red strands (r). If each pom-pom has a total of 80 strands, how many of strands of each color are needed to make a pair of pom-poms? In this activity, you’ll work through this pom-pom problem step by step.
Part E
Now solve for w, b, and r for a pair of pom-poms using the total number of strands you found in part D. Solve three proportions similar to the work you did in Part B. Show your calculations.
Answers
Answer:
w: 56
b: 40
r: 64
Step-by-step explanation:
A pair of pom-poms need: 80 × 2 = 160 (strands)
To make a pair of pom-poms:
w: 160 × 35% = 56 (strands)
b: 160 × 25% = 40 (strands)
r: 160 × 40% = 64 (strands)
28 white, 20 blue and 32 red strands are needed to make a pair of pom-poms.
What is percentage?Percentage is defined as ratio expressed as a fraction of 100.
Given that, total Strands = 80
∵white strands = 35%
w = 35%×80 =
w= 35/100×80
w = 28
∵blue strands = 25%
b = 25%× 80
b = 25/100× 80
b = 20
∵red strands = 40%
r = 40%× 80
r = 40/100× 80
r = 32
Thus, 28 white, 20 blue and 32 red strands are needed to make a pair of pom-poms.

Answers
Area of rectangle ABCD is, 32 units²
And, Perimeter of rectangle is, 24 units
We have to given that,
A rectangle ABCD is shown in image.
And, Coordinates are,
A = (- 5, 5)
B = (- 1, 5)
C = (- 5, - 3)
D = (- 1, - 3)
Now, We can use the distance formula for finding the length and width of rectangle.
Lenght (AC) = √(- 5 + 5)² + (5 + 3)²
AC = √8²
AC = 8
Width (AB) = √(- 5 + 1)² + (5 - 5)²
AB = √16
AB = 4
Therefore, Area of rectangle ABCD is,
Area = Length × Width
Area = 8 × 4 = 32 units²
Perimeter of rectangle is,
P = 2 (Length + Width)
P = 2 (8 + 4)
P = 2 × 12
P = 24 Units

The vertex and [tex]x-[/tex]intercepts of the graph of [tex]y= x^2 - 6x - 7[/tex] will be [tex](3,-16)[/tex] and [tex](7,-1)[/tex], respectively.
What are vertex and [tex]x-[/tex]intercepts of the graph?A vertex in a quadratic equation is the minimum or maximum point of the equation and an [tex]x-[/tex]intercept of a graph is the point at which the graph intersects the [tex]x-[/tex]axis.
Vertex form, [tex]y=a(x-h)^2+k[/tex]
We have,
[tex]y= x^2 - 6x - 7[/tex]
Now,
Find the [tex]x-[/tex]intercept and to find [tex]x-[/tex]intercept put [tex]y=0[/tex] ;
i.e. [tex]y= x^2 - 6x - 7[/tex]
[tex]0= x^2 - 6x - 7[/tex]
[tex]x^2 - 6x - 7=0[/tex]
Now using Mid-term split method find value of [tex]x[/tex];
[tex]x^2 - 7x+1x - 7=0[/tex]
[tex]x(x - 7)+1(x - 7)=0[/tex]
[tex](x - 7)(x +1)=0[/tex]
[tex](x - 7)=0[/tex]⇒[tex]x=7[/tex]
[tex](x +1)=0[/tex]⇒[tex]x=-1[/tex]
So, these are the [tex]x-[/tex]intercept [tex](7,-1)[/tex] of the expression.
Now find the vertex using the above given formula;
[tex]y=a(x-h)^2+k[/tex]
Rewrite in vertex form
[tex]y= x^2 - 6x - 7[/tex]
Add and subtract [tex](-3)^2[/tex] in given expression;
[tex]y= x^2 - 6x + (-3)^2 -7 - (-3)^2[/tex]
[tex]y = x^2 - 6x + 9 -7 - 9[/tex]
[tex]y = x^2 - 6x + 9 -16[/tex]
Now convert quadratic part of equation in [tex](a-b)^2[/tex];
[tex]y = (x-3)^2-16[/tex]
Now compare it with [tex]y=a(x-h)^2+k[/tex]
We get, [tex]h=3,\ k=-16[/tex]
So, these are the vertex [tex](3,-16)[/tex] of expression.
Hence, we can say that the vertex and [tex]x-[/tex]intercepts of the graph of [tex]y= x^2 - 6x - 7[/tex] will be [tex](3,-16)[/tex] and [tex](7,-1)[/tex], respectively.

Answers
Answer:
The range of the Morning box plot is the same as the range of the Afternoon box plot.
Step-by-step explanation:
Data provided in the question
Number line = 0 to 16
Morning whiskers range = 3 to 15
Box range = 5 to 12
Line divided = 8
Afternoon whiskers range = 4 to 16
Box range = 8 to 15
Line divided = 14
Based on the above information,
The morning whiskers range difference is
= 12 - 5
= 7
And, the afternoon whiskers range difference is
= 15 - 8
