6. (a) Find a recurrence relation for the number of n-digit binary sequences with no pair of consecutive 1s. (b) Repeat for n-digit ternary sequences
(a) There are 2 sequences of length 1 that fit the bill: 0 and 1. So if [tex]b_n[/tex] is the number of permissible sequences, then [tex]b_1=2[/tex].
To the sequence 0, we can attach either 0 or 1 at the end, while the sequence 1 must be followed by 0. Then the permissible sequences of length 2 are 00, 01, and 10, so [tex]b_2=3[/tex].
Now consider a sequence of length n + 1, of which there are [tex]b_{n+1}[/tex].
• If the last digit is 0, then we got this sequence by simply joining 0 to one of [tex]b_n[/tex] sequences. In other words, there are [tex]b_n[/tex] permissible sequences of length n + 1 that end in 0.
• If the last digit is 1, then the previous digit must have been 0. Put another way, we join 01 to a permissible sequence of length n - 1 (there are [tex]b_{n-1}[/tex] of them). So there are [tex]b_{n-1}[/tex] permissible sequences of length n + 1 that end in 1.
These cases are mutually exclusive, so the number of (n + 1)-length permissible sequences is given by
[tex]\begin{cases}b_1 = 2 \\ b_2 = 3 \\ b_{n+1} = b_n + b_{n-2} & \text{for }n\ge2\end{cases}[/tex]
(b) The reasoning for a permissible ternary sequence is similar. Let [tex]t_n[/tex] be the number of sequences of length n not containing 11.
We first note that [tex]t_1 = 3[/tex], since we can have 0, 1, or 2; and [tex]t_2 = 8[/tex], since we can have 00, 01, 02, 10, 12, 20, 21, or 22.
Consider a sequence of length n + 1 ([tex]t_{n+1}[/tex] of these).
• If the last digit is 0, then we joined 0 to a permissible sequence of length n. So there are [tex]t_n[/tex] permissible sequences of length n + 1 ending in 0.
• If the last digit is 1, then the last two digits must be either 01 or 21. Since there are 2 choices for the n-th digit, there are [tex]2t_{n-1}[/tex] permissible sequences of length n + 1 ending in 1.
• If the last digit is 2, then we essentially have the same situation as if the sequence ended in 0, so there are [tex]t_n[/tex] sequences of length n + 1 ending in 2.
Then the recurrence for ternary permissible sequences is
[tex]\begin{cases}t_1 = 3 \\ t_2 = 8 \\ t_{n+1} = 2t_n + 2t_{n-1} & \text{for }n\ge2\end{cases}[/tex]

Juanita borrowed $600 to purchase a new computer. She was charged 7% interest for two years. She used the simple interest formula to find the interest.
I = 600(7)(2)
What error did Juanita make and how will her error affect the interest she calculates? Explain.
please help
Answer:
The error she made was multiplyng by 7. This would affect her calculations as 7 in percentage form is represented as 700%. The 700% interest would basically mean she owes 7 times the amount she borrowed. The correct number would be 0.07 because 0.07 represents 7% which is the interest. Another error that was made was multiplying 2 to the entire equation. The only thing that needs to be doubled is the interest as every year the interest takes 7%. The correct way would be to put 0.07*2 in paranthesis. The correct equation is
I = 600(0.07*2)
6/23 divided by 1/5 plz help
Answer:
30 / 23
Step-by-step explanation:
to divide two fractions, multiply by the reciprocal.
The reciprocal of 1/5 is 5/1. We will rewrite the equation as:
[tex]\frac{6}{23}[/tex] times [tex]\frac{5}{1}[/tex]
6 x 5 = 30
23 x 1 = 23
the answer is 30 / 23
The Quotient is 30/23.
What is Division?One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things.
Given:
6/23 divided by 1/5
As, division is not possible in fraction so we will perform the multiplication
= 6/23 ÷ 1/5
= 6/23 x 5
= 30/ 23

Irene is N years old. If Tom is twice as old, which of the following algebraic statements shows his age now?
A. 2n
B. 2n + x
C. 2 - n
D. n - 2
Explanation:
The n is a placeholder for a number. Writing 2n means we multiply by 2.
For example, if Irene is n = 20 years old, then Tom is 2n = 2*20 = 40 years old.

If using the method of completing the square to solve the quadratic equation
x^2+2x – 31 = 0, which number would have to be added to "complete the
square"?
==
Answer:
See belowStep-by-step explanation:
Given equation:
x² + 2x - 31 = 0Complete square as follows:
x² + 2x + 1 - 31 = 1(x + 1)² = 32x + 1 = ± √32x = - 1 ± 4√2Step-by-step explanation:
We need to solve the equation using completing the square method .
=> x² - 2x - 31 = 0
=> x² -2*1*x + 1² - 1² - 31 = 0
=> ( x -1)² - 32 = 0
=> (x+1)² = 32
=> x +1 = ±√32
=> x = ±4√2 - 1

Given that a survey asked the question, "Do you think a vaccination should be mandatory to enter shopping areas?" to a random sample of 1068 Jordanians, and the results showed that 71.2% responded that vaccination should mandatory, to determine which of the following is an observation, a variable, a sample statistic (value calculated based on the observed sample), or a population parameter, the following statistical reasoning must be performed:
(a) A Jordanian that was asked the question.
-An observation, as the person questioned is part of the study and therefore, it is an individual observation that makes up the trend.
(b) The response of the Jordanian.
-A variable, since it is one of the two possible answers that the survey has.
(c) 71.2%.
-A population parameter, because it represents a specific percentage with respect to the total population.
(d) The percentage of all Jordanians who agreed with the statement that vaccination should be mandatory to enter shopping areas.
-A sample statistic, since it is a statistical element that arises from the survey.

Two sides of a triangle are 11 can and 14 cm what are all the possible values for the length of the third side
Answer:
Step-by-step explanation:
The third side is thus, less than 14 + 11 = 25 cm. The side cannot be less than the difference of the two sides. Thus, the third side has to be more than 14 - 11 = 3 cm. So, the length of the third side could be any length greater than 3 cm and less than 25 cm.

Find the gradient of the line segment between the points (4,6) and (8,14).
Let a = (x1,y1) = (4,6) and b = (x2,y2) = (8,14)
Then, since the formula of the gradient (or Slope), given two points a and b is :
m = (y2 - y1) / (x2-x1) = (14 - 6) / (8 - 4) = 8 / 4 = 2
Then we know that the gradient is m = 2

Find the length of line AC in the following picture.
I've been at a loss at how to do this one for a while. Someone, please help? No links, no spam. If you don't know the answer, then don't answer.
Answer:
12.72 m
Step-by-step explanation:
You're going to use the left side from the middle of AD up to point A. You see that's the same as a radius, so its length is 4.5. Then you can use the Pythagorean theorem to find the hypotenuse, the blue line from X to A.
(4.5)^2+(4.5)^2=x^2
40.5=x^2
x=6.36
and AC is two of the line you just figured out so 6.36x2=12.72m
