Step-by-step explanation:
6x + 13 = 2x + 1
6x -2x = 1-13
4x = -12
x = -12/4 = -3
y = 6x + 13
y = 6(-3) +13 = -18+13 = -5
(x, y) = (-3,-5)

Polina’s math scores are shown in the table. Polina’s Math Scores Math Scores 72 65 75 88 90 What is the mean absolute deviation of her math scores? 5.4 6.4 7.8 8.8
The mean absolute deviation of Polina's math scores is 8.8.
The answer is D) 8.8.
What is the mean absolute deviation?
The mean absolute deviation (MAD) is a measure of variability that quantifies the average difference between the observations in a dataset and the dataset's mean. It is calculated by finding the average of the absolute deviations of the data points from their mean.
To find the mean absolute deviation (MAD) of Polina's math scores, we first need to find the mean of the scores:
Mean = (72 + 65 + 75 + 88 + 90)/5
Mean = 78
Next, we find the absolute deviation of each score by finding the difference between each score and the mean, taking the absolute value of the difference, and then adding up the absolute differences:
|72 - 78| = 6
|65 - 78| = 13
|75 - 78| = 3
|88 - 78| = 10
|90 - 78| = 12
Sum of absolute deviations = 6 + 13 + 3 + 10 + 12
Sum of absolute deviations = 44
Finally, we find the MAD by dividing the sum of the absolute deviations by the number of scores:
MAD = 44/5
MAD = 8.8
Therefore, the mean absolute deviation of Polina's math scores is 8.8.
The answer is D) 8.8.

] Consider a randomly shuffled deck of ten cards labeled {1, 1, 2, 2, 3, 3, 4, 4, 5, 5}, of which game play requires three to be drawn. Which one should be worth more points: A getting a pair of matching cards within the three, or B getting a set of three cards that can be arranged such that the sum of two of them is the value of the third (e.g. 1 2
Answer:
B should be worth more points.
Step-by-step explanation:
Given - Consider a randomly shuffled deck of ten cards labeled
{1, 1, 2, 2, 3, 3, 4, 4, 5, 5}, of which game play requires three
to be drawn.
To find - Which one should be worth more points:
A getting a pair of matching cards within the three,
or B getting a set of three cards that can be arranged such
that the sum of two of them is the value of the third.
Proof -
Given that, three cards has to be drawn.
So, total number of ways the card be drawn = ¹⁰C₃
= [tex]\frac{10!}{3! (10-3)!}[/tex]
= [tex]\frac{10!}{3! 7!}[/tex]
= [tex]\frac{10.9.8.7!}{3! 7!}[/tex]
= [tex]\frac{10.9.8}{3.2.1}[/tex]
= 120
⇒¹⁰C₃ = 120
Now,
Given that, A getting a pair of matching cards within the three
Sample space = { (1,1,2), (1,1,3).(1,1,4),(1,1,5);
(2,2,1),(2,2,3),(2,2,4),(2,2,5);
(3,3,1),(3,3,2),(3,3,4),(3,3,5);
(4,4,1),(4,4,2),(4,4,3),(4,4,5);
(5,5,1),(5,5,2),(5,5,3),(5,5,4) }
⇒n(A) = 20
Also,
B getting a set of three cards that can be arranged such that the sum of two of them is the value of the third
Sample space = { (1,1,2),(1,2,3),(1,3,4),(1,4,5),(2,2,4),(2,3,5) }
⇒n(B) = 6
Now,
P(A) = [tex]\frac{20}{120} = \frac{1}{6}[/tex] = 0.167
P(B) = [tex]\frac{6}{120} = \frac{1}{20}[/tex] = 0.05
We can see that, P(B) < P(A)
⇒B should be worth more points.

ABC measures 140° and is bisected
by BD. What is mDBC= ?
Answer:
angle abc =140°
and bd bisected by bd so, bd divede angle abc.
angle dbc= angle abc / 2
angle dbc=140°/2
angle dbc=70°
The measure of angle DBC from the given figure is 70°.
The measure of angle ABC is 140°.
What is an angle bisector?The angle bisector in geometry is the ray, line, or segment which divides a given angle into two equal parts.
Angle bisector BD is bisecting angle ABC equally, which is
∠ABC=∠ABD+∠DBC
⇒ 140°=∠DBC+∠DBC
⇒ 2∠DBC=140°
⇒ ∠DBC=70°
Therefore, the measure of angle DBC from the given figure is 70°.

Step-by-step explanation:
Ok...
Get ready to see Alot more numbers
1. Rearrange terms.
12x-15=6-3x
12x-15=-3x+6
2. Add 15 to both sides.
12−15=−3+6
12−15+15=−3+6+15
3. Simplify
If you add the numbers you will get:
12x=-3x+21
4. Add 3x to both sides of the equation.
12x=-3x+21
12x+3x=-3x+21+3x
5. Simplify
If you combine the like terms you will get,
15x=21
6. Divide both sides of the equation by the same term.
15x=21
[tex]\frac{15x}{15}[/tex] = [tex]\frac{21}{15}[/tex]

Pre calculus law of sines
Answer:
AB = 6.5
Step-by-step explanation:
C = 59°
AC = 7
CD = 6
AB = ?
Apply the Law of Cosines, which is AB² = AC² + CD² - 2(AC)(CD)*Cos(C)
AB² = 7² + 6² - 2(7)(6)*Cos(59)
AB² = 85 - 43.26
AB² = 41.74
AB = √41.74
AB = 6.5 (nearest tenth)
Constructed line PQ is the _______________ of line segment CD.
Answer:
Perpendicular bisector
Step-by-step explanation:
Construction done:
1). An arc is drawn from point O which intersects line 'l' at two points C and D.
2). From the points C and D two equal arcs on both the sides of the line 'l' have been drawn intersecting each other at points P and Q.
3). Points P and Q have been joined with the help of a straightedge.
Hence constructed line PQ is the PERPENDICULAR BISECTOR of the line segment CD.
