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

Answers
Answer:
The answer is A
Step-by-step explanation:
It doesn't matter which side the coin landed on in the previous flips. The coin only has 2 sides, heads and tails. Therefore, when it's flipped the 6th time, there is a 50% chance it will land on heads, and a 50% chance that it will land on tails. The answer is A.

1. You have the following ratio given in the problem above:
11:1
2. You can rewrite that ratio as below:
11/1=11
3. Then, to find three equivalent ratios, you only need to multiply the numerator (11) and the denominator (11) by the sam number. Therefore, you have:
11x2/1x2=22/2=11
11x3/1x3=33/3=11
11x4/1x4=44/4=11

A recipe uses 5 cups of milk to make 20 servings. If the same amount
of milk is used for each serving, how many servings can be made from
two pints?
1 gallon 4 quarts
1 quart 2 pints
1 pint 2 cups
1 cup = 8 fluid ounces
Before you try that problem, answer the question
below.
How many cups will you need to find the number
of servings for?
Answers
Answer:
16 servings
Step-by-step explanation:
The recipe would use 2 pints or 4 cups of milk. 1 cup of milk is equal to 4 servings (20/5 = 4), so 4 cups would make 16 servings.
1 pint is equal to 2 cups so 2 pints will be 4 cups.
The number of servings 2 pints will make is 16 servings.
What is a unit rate?A unit rate means a rate for one of something.
It is written as a ratio with 1 as the denominator.
We have,
5 cups of milk = 20 servings
Multiplying 1/5 on both sides.
1/5 x 5 cups of milk = 1/5 x 20 servings
This means,
1 cup of milk = 4 servings
We know that,
1 pint = 2 cups
Multiplying 2 on both sides
2 x 1 pints = 2 x 2 cups
2 pints = 4 cups
If,
1 cup = 4 servings
4 cups = 4 x 4 servings
4 cups = 16 servings
Thus the number of servings 2 pints will make is 16 servings.

The probability of getting not blue marble is [tex]\frac{7}{8}[/tex].
What is probability?
Probability is a measure of happening or non-happening of the outcomes of a random experiment.
Probability formulaP(E) = number of favorable outcomes/ total number of outcomes
According to the given question.
Total number of red marbles = 5
Total number of yellow marbles = 4
Total number of green marbles = 5
Total number of blue marbles = 2
⇒ Total number of marbles = 5 + 4 + 5 + 2 = 16
So, total number of outcomes = 16
Now, probability of getting blue marble = [tex]\frac{2}{16} = \frac{1}{8}[/tex]
Therefore, the probability of getting not blue marble = [tex]1 -\frac{1}{8} =\frac{7}{8}[/tex]
Hence, the probability of getting not blue marble is [tex]\frac{7}{8}[/tex].

solve this system using elimination. 3x - 4y = -5, -10x + 4 = 12
Answers
Answer:
x = -4/5, y = 13/20
Step-by-step explanation:
-10x + 4 = 12
-10x = 8
x = -4/5
3x - 4y = -5
3(-4/5) - 4y = -5
-12/5 - 4y = -5
-4y = -13/5
y = 13/20
Double check:
3x - 4y = -5
3(-4/5) - 4(13/20) = -5
-12/5 - 13 = -5 (true)
