Finish the sequence
1,1,2,3,5,8,_,_,_

Answers

Answer 1

Answer: This is a Fibonacci sequence
1; 1
1 + 1 = 2
1 + 2 = 3
2 + 3 = 5
3 + 5 = 8
next terms:
5 + 8= 13
8 +13 = 21
13 + 21 = 34

Answer 2

Answer: The Fibonacci sequence has to be thought of in these terms:

F₀, F₁, F₂, F₃, F₄, F₅, F₆, F₇, etc, etc

----------------------

Now:

F₀=0

F₁=1

The formula you use to get the other numbers is:

$F_(n) = F_(n-1) + F_(n-2)$

--------------

So:

$F_(2) = F_(2-1) + F_(2-2) = F_(1) + F_(0) =1+0=1$

And:

$F_(3)= F_(3-1) + F_(3-2) = F_(2) + F_(1) =1+1=2$

------------

If you continue using the formula, you should get a sequence that starts off like this:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, etc, etc

I put $200 in a saving account with 7% interest a year. How much will i have in 19 years

Answers

it would be 200×0.07= 14×19= 266

I = PRT
P for Principle Amount
R for Rare
T for Time in years

I = 200 × 0.07 × 19 (70% = $(7)/(100)$ = 0.07)
= $266 - this is the interest

You will have 200 + 266 = $466 in your account

the average amount of annual interest earned across three investment accounts was $2709.00. If one account yielded $1345.00 in the 12 month period, and the second yielded $568.00, what did the thrid account yield?

Answers

The interest of the third investment to have an annual interest earning of 2,709 would be 6,214. This is calculated using the formula: average = (a+b+c ) / 3. By substituting it would be, 2,709 = (1,345 + 568 +x) / 3. Then it would be 8,127 = 1,345 + 568 +x and by transferring the figures, it will be then 6,214.

Solve the system of equations 3x+2y=14 2x-4y=4

Answers

3x + 2y = 14....multiply by 2
2x - 4y = 4
----------------
6x + 4y = 28 (result of multiplying by 2)
2x - 4y = 4
----------------add
8x = 32
x = 32/8
x = 4

2x - 4y = 4
2(4) - 4y = 4
8 - 4y = 4
-4y = 4 - 8
-4y = -4
y = -4/-4
y = 1

solution is (4,1)

B. normal (approximately)
C. not enough information provided
D. skewed to the right

Answers

The answer in B. For complicated statistics reasons the Central Limit Theorem states that, for sample sizes of above 25 (or 30 depending on the text!), the distribution of sample means is approximately normal regardless of the distribution of the parent distribution
