Answer:
Each term is a sum of the two previous terms like the fibonacci sequence, but the sum of the two starting terms of the lucas sequence is followed by 2 then 1, rather than 0 then 1 for the fibannaci sequence.
These are integer sequences.
The sum of the two previous terms can be represented by:
fn = fn-1 + fn-2.
These numbers can be obtained by adding the previous corresponding term of the fibonacci sequence by the next corresponding term to get the corresponding number of the lucas sequence.
Ln = { 2 if n = 0
1 if n = 1
Ln-1 + Ln-2 if n > 1
________________
Fn+1 + Fn-1 = Ln
___________________
f(0) = -1
f(1) = 2, f(2) = 1, f(3) = 3, f(4) = 4, f(5) = 7, f(6) = 11
________________________________
f(12) = 199
________
f(12) = f(11) + f(10) = (f(10) + f(9)) + (f(9) + f(8)) = .....
given f(n) = f(n-1) + f(n-2)
____________________
f(12) = f(1) + f(2) = f(2) + f(3) = f(3) + f(4) =
f(4) + f(5) = f(5) + f(6) = f(6) + f(7) =
f(7) + f(8) = f(8) + f(9) = f(9) + f(10) =
f(10) + f(11) = f(12) →
f(12) = 2 + 1 = 1 + [3] = 3 + [4] = 4 + [7] =
7 + [11] = 11 + [18] = 18 + [29] = 29 + [47] =
47 + [76] = 76 + [123] = 199

Explicit formula
for n is an integer.
Nth term of the lucas sequence.

The list of numbers 41, 35, 30, X, Y, 15 has a median of 25. The mode of the list of numbers is 15. To the nearest whole number, what is the mean od the list?
Answer:
1.2
Step-by-step explanation:
1.Arrange the numbers in order by size.
15,20,25,30,35,41
2.If there is an odd number of terms, the median is the center term.
with these numbers they are even (6 numbers total)
3.If there is an even number of terms, add the two middle terms and divide by 2.
30 ÷ 25=1.2

Three sisters are saving for a special trip . The ratio of Nora's savings to Helga's savings is 8:3 and the ratio of Helga's savings to Maurice's savings is 3:4. Together all 3 have saved $60. How much has each saved?
Answer:
X = 10.588
Y = 28.2
Z = 21.176
Step-by-step explanation:
Consider Nova savings as X
Helga is Y
Maurice is Z
As per first ratio we conclude 8X=3Y
Second ratio we conclude 3Y = 4Z
We deduce 8X = 4Z
Last sentence => X+Y+Z=60 multiple it by 3
=> 3X + 3Y + 3Z= 180 but 8X = 4Y
=> 3X + 8X + 3Z =180 => 11X + 3Z=180 multiple the equation by 4/3
44/3 X + 4Z = 240 but 4Z = 8X
=> 44/3 X + 8 X = 240
=> 68/3 X = 240
=> 68X = 720
=> X =10.588
And Y=8/3 X =28.2
And Z=3/4 Y = 21.176

Clarence made a diagram to compare codominance and incomplete dominance. Which label belongs in the area marked Y? Neither allele is dominant. An intermediate phenotype is expressed in offspring. One allele is dominant over the other. Both dominant alleles are fully expressed in offspring.
Answer:
The correct answer is both dominant alleles are fully expressed in offspring.
In the incomplete dominance inheritance, one allele is not completely expressed over its paired allele and forms an intermediate trait, whereas in co-dominance, both the alleles express completely resulting into a new phenotype. For example AB blood group in humans.
In the given question Y is the intersection of co-dominance set and incomplete dominance set. Thus, the area Y may have one dominant allele from co-dominance and one allele which is not completely dominant from incomplete dominance.
Therefore, the label to marked area Y may be - both dominant alleles are fully expressed in offspring.

10) c) 215
Step-by-step explanation:
Step:1
Given that the expression

Put r = 9
= [tex]\frac{31+9}{2} - \frac{9(9)-5}{4}[/tex]
= [tex]\frac{40}{2} -\frac{76}{4}[/tex]
= 20 - 19
=1
Step(ii):-
Given that
[tex]\frac{5(4r-16)}{5} +13(3r-12)[/tex]
Put r = 9
= [tex]\frac{5(4(9)-16)}{5} +13(3(9)-12)[/tex]

Which of these best represents the function shown in the table?
f(x) = 2(4*)
0
f(x) = x + 2
f(x) = 6x + 2
f(x) = x5
Answer:
c: f(x) = 2(4^x)
Step-by-step explanation:
the table shows that the function is exponential rather than linear.
The best that represents the function shown in the table;
c: f(x) = 2(4^x)
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable. In mathematics and the physical sciences, functions are indispensable for formulating physical.
Thus, the table shows that the function is exponential rather than linear.
We are given the table through which we have to make a function.
The function becomes as;
[tex]f(x) = 2(4^x)[/tex]
This function shows exponential rather than linear.

Bobby rode his skateboard 4 miles 30 rode her bicycle 10 miles in minutes. Who traveled at a greater average speed? Define an appropriate unit of speed and provide mathematical justification for your answer.
Answer:
Abelito had the greater average speed
Step-by-step explanation:
Given
Bobby:
[tex]Distance =4\ miles[/tex]
[tex]Time = 30\ minutes[/tex]
Abelito
[tex]Distance = 10\ miles[/tex]
[tex]Time = 48\ minutes[/tex]
Required:
Who had a greater average speed
Average speed (S) is calculated as:
[tex]S = \frac{Distance}{Time}[/tex]
We will make use of mph (miles per hour) as the unit of speed.
For Bobby:
[tex]S_B = \frac{4\ miles}{30\ minutes}[/tex]
Convert minute to hour
[tex]S_B = \frac{4\ miles}{0.5\ hr}[/tex]
[tex]S_B = 8mph[/tex]
For Abelito
[tex]S_A = \frac{10\ miles}{48\ minutes}[/tex]
Convert minute to hour
[tex]S_A = \frac{10\ miles}{0.8\ hr}[/tex]
[tex]S_A = 12.5mph[/tex]
By comparison: 12.5mph > 8mph
Hence: Abelito had the greater average speed

If for every 12 blue streamers there is 9 gold streamers, how many blue streamers will I have if I have 36 gold streamers?
Answer:
You will have 48 blue streamers.
Step-by-step explanation:
This question can be solved by proportions, using rule of three.
We have that:
For 12 blue streamers, there are have 9 gold streamers. How many blue streamers are there when there are 36 gold streamers?
12 blue - 9 gold
x blue - 36 gold
Applying cross multiplication
[tex]9x = 36*12[/tex]
Simplifying by 9
[tex]x = 4*12 = 48[/tex]
You will have 48 blue streamers.

Round answer to the nearest hundredth if necessary.
20
160/8=20
88/8=11
i hope this one helps !!
Answer:
20,020 in. on the plans
Step-by-step explanation:
To get from 11 in. to 88 in. (from plans to real life), you multiply by 8.
Therefore, to get from 160,160 to ?? (from real-life to plans), you would divide by 8.
160,160 / 8 = 20,020
To check, you can multiply 20,020 by 8 to go from plans to real-life measurements; 20,020 • 8 = 160,160)

Daniel bought a total of 8 pounds if peanuts and cashews. Peanuts, p, cost $2 per pound and cashews, c, cost $5 per pound. The total amount Dani spent on the peanuts and cashews was $25. Which system of equations could be solved to find how many pounds kf peanuts dani bought
A.{2p+5c=25
p+c=9
B.{5p+2c=25
p+c=8
C.{2p+5c=8
p+c=25
D.{2p=8
5c=25
Answer:
I believe the answer is C.
Step-by-step explanation:
given we have peanuts to be $2 per pound, and cashews $5 per pound. If we use the equation p+c=25 then p would be (2×10=20), and c would be (5×1=5). then, to solve the problem we would do p+c=25 which p would be 20, and c would be 5, then add and it would equal 25.
