Answer:
B (2, 4)
Step-by-step explanation:
A (-1,-9); M (0.5, -2.5); B (xB, yB)
M is the midpoint of AB, therefore we have these 2 equations:
(*) xA + xB = 2. xM
(**) yA + yB = 2. yM
(*) <=> xB = 2. xM - xA = 2x0.5 - (-1) = 1 + 1 = 2
(**) <=> yB = 2. yM - yA = 2x(-2.5) - (-9) = -5 + 9 = 4
So, B (2, 4)

Option B is the correct answer.
What is a series of patterns?A series of patterns is a sequence of related designs, shapes, colors, or other elements that follow a consistent and predictable order.
The patterns may repeat or vary in a systematic way, creating a sense of rhythm, symmetry, or harmony.
We have,
From the series of patterns, we see that,
The number of arrows is increasing in odd arithmetic numbers.
So,
1, 3, 5,
The next step must have 7 arrows.
And,
The color is alternated as:
Red, Blue, Red Blue.

Improper Fraction: [tex]\frac{10}{6}[/tex]
Proper Fraction: [tex]1\frac{4}{6}[/tex]
Simplified Proper Fraction: [tex]1\frac{2}{3}[/tex]
Step-by-step explanation:
[tex]\frac{5}{6} + \frac{2}{3}[/tex] Is our equation... first we must find a common denominator! Let's take a look...
6: 1, 6, 12
3: 1, 3, 6
We see that both numbers get to 6 so we use that as our common denominator. Now we plug that in...
[tex]\frac{5*1}{6*1} +\frac{2*2}{3*2}[/tex]
We get...
[tex]\frac{5}{6} +\frac{4}{6} = \frac{10}{6}[/tex]
Now if you want to leave it as an improper fraction your answer will be [tex]\frac{10}{6}[/tex]. However, if you want you answer to be a proper fraction your answer is [tex]1\frac{4}{6}[/tex] which can be simplified further to,[tex]1\frac{2}{3}[/tex].

Lawrence High prevailed in Saturday's track
meet with the help of 20 individual event
placers earning a combined 68 points. A
first place finish earns 5 points, a second-
place finish earns 3 points, and a third-place
finish earns 1 point. Lawrence had a strong
second-place showing, with as many second
place finishers as first and third-place
finishers combined.
Answer:
The answer is below
Step-by-step explanation:
Let x represent a first place finish, y represent a second place finish and z represent a third place finish.
Since there is a total of 20 individual events, hence:
x + y + z = 20 (1)
A first place finish is 5 point, a second place finish is 3 point and third place finish is 1 point. Therefore:
5x + 3y + z = 68 (2)
The second place finishers is as much as first and third-place finishers combined. Hence:
y = x + z (3)
Solving equation 1, 2 and 3 simultaneously gives:
x = 7, y = 10 and z = 3
This means the number of first place finishes was 7, second place finishes was 10 and third place finishes was 3

I have tried 3 times to solve this.
Step-by-step explanation:
Year 2006- y = 0.09 (6) + 0.04 = 0.58
Year 2008- y = 0.09 (8) + 0.04 = 0.76
Year 2010- y = 0.09 (10) + 0.04 = 0.94
Year 2012- y = 0.09 (12) + 0.04 = 1.12
Year 2014- y = 0.09 (14) + 0.04 = 1.3
"Let x = 6 which is corresponded to 2006", so 8 would correspond to 2008, 10 would correspond to 2010, 12 would correspond to 2012, and 14 would correspond to 14. Plug 6 for x into your equation and do them same for the others.
Hopefully this helps you! :)
Which of these choices is equivalent to the expression: i85
Answer:
[tex]i^{85} = i[/tex]
Step-by-step explanation:
The options are missing; however, the question can still be solved.
Given
[tex]Number = i^{85}[/tex]
Required
Simplify
[tex]Number = i^{85}[/tex]
Rewrite 85 as 84 + 1
[tex]Number = i^{84 + 1}[/tex]
Split the expression using the law of indices
[tex]Number = i^{84} * i^1[/tex]
Rewrite 84 as 4(21)
[tex]Number = (i^{4})^{21} * i^1[/tex]
In complex numbers, [tex]i^4 = 1[/tex]
So, we have
[tex]Number = 1^{21} * i^1[/tex]
[tex]Number = 1 * i[/tex]
[tex]Number = i[/tex]
Hence;
[tex]i^{85} = i[/tex]
A random sample of adults were asked whether they prefer reading an e-book over a printed book. The survey resulted in a sample proportion of p′=0.14, with a sampling standard deviation of σp′=0.02, who preferred reading an e-book.
Answer:
The confidence interval is (0.1008, 0.1792)
Step-by-step explanation:
According to the question, the data provided is as follows
p′=0.14
sampling standard deviation of σp′= 0.02
Based on the above information
The computation of the 95% confidence interval for the true or correct proportion is
Here we apply the z value of 95% confidence interval i.e. 1.96
Now the confidence interval is
[tex]= (pcap - z\times sigma, pcap + z\times sigma)\\\\= (0.14 - 1.96\times 0.02, 0.14 + 1.96\times 0.02)\\\\= (0.1008, 0.1792)[/tex]

Can anyone help me with this question ?
Answer:
addition
Step-by-step explanation:
18 ( d - 9 ) = 198
3
divide both side by 18
d - 9 = 198
3 18
d - 9 = 11
3
multiply both sides by 3
d - 27 = 33
add 27 to both sides
d = 33 + 27
lastly, add them together
d = 60
therefore, the last step is addition

A vehicle factory manufactures cars. The unit cost (the cost in dollars to make each car) depends on the number of cars made. If cars are made, then the unit cost is given by the function . What is the minimum unit cost? Do not round your answer.
Answer:
The function is missing in the question. The function is [tex]$ C(x) = 0.8x^2 -544x +97410 $[/tex]
The answer is 4930
Step-by-step explanation:
Unit cost of a car is given as
[tex]$ C(x) = 0.8x^2 -544x +97410 $[/tex]
Cost will be minimum when
x = -(-544)/ 2 x 0.8
= 340
Therefore, minimum cost for unit car is
[tex]$ C(x) = 0.8x^2 -544x +97410 $[/tex]
[tex]$ = 0.8(340)^2 -544(340) +97410 $[/tex]
= 4930

If a+b+c=9 ab +bc+ca=12 find a2+b2+c2
Step-by-step explanation:

Therefore 9^2 = (a^2 + b^2 + c^2) + 2(12).
a^2 + b^2 + c^2 = 81 - 24 = 57.

Elegant Home Architects charge $75.00 per hour for the house plans. Let a represent the number of hours for which the Johnson family hires the design firm. Which of the following statements are true? Select all that apply.
Answer:
Statement 2, Statement 4, and Statement 5 all applies
Step-by-step explanation:
Statement 1:
The expression 50ℎ represents the total charge for Rock the House Digital Designs.
Rock the House Digital Designs:
Initial consultation charge of $500 + $50 for every additional hour of work for the house plans
500 + 50h
NOT TRUE
Statement 2:
The expression 75ℎ represents the total charge for Elegance Home Architects.
Elegance Home Architects:
$75 per hour for the house plans

NOT TRUE
Statement 4:
If the Johnson family hires the design firm for 15 hours, then Elegance Home Architects will be cheaper.
Rock the House Digital Designs = 500 + 50h
500 + 50(15)
= 500 + 750
= $1,250
Elegance Home Architects = 75h
= 75(15)
= $1,125
TRUE
Statement 5:
If the Johnson family hires the design firm for 40 hours, then Rock the House Digital Designs will be cheaper.
Rock the House Digital Designs = 500 + 50h
= 500 + 50(40)
