1.)Given the recursive definition LaTeX: a_{n+1}=2\cdot a_n+1a n + 1 = 2 ⋅ a n + 1, and that LaTeX: a_1=1a 1 = 1, find LaTeX: a_

Answer:

1) 1023

2) 8

Step-by-step explanation:

1)

Given:

$a_{n+1}=2\cdot a_n + 1$ and $a_1 = 1$

Then, the next table can be computed (only the first terms are explicitely shown)

n $a_n$

1 1

2 $a_{2}=2\cdot 1 + 1 =$ 3

3 $a_{3}=2\cdot 3 + 1 =$ 7

4 15

5 31

6 63

7 127

8 255

9 511

10 1023

2)

Given

$t_n=n^2-2n$

Then, the next table can be computed

n $t_n$

1 $t_1=1^2-2(1) =$ -1

2 $t_2=2^2-2(2) =$ 0

3 $t_3=3^2-2(3) =$ 3

4 $t_4=4^2-2(4) =$ 8

AutoTrader would like to test if a difference exists in the age of three different types of vehicles currently on the road: truc

liubo4ka [24]

Answer:

16

Step-by-step explanation:

Remember that the general formula for SSTR is

$SSTR = n_1(\bar{x_1}-\bar{x})+...+n_k(\bar{x_k}-\bar{x})$

For this problem

$\bar{x} = 8$

$n_1 = n_2 = n_3 = n_4 = 4$

then

$n_1(\bar{x_1}-\bar{x})+...+n_k(\bar{x_k}-\bar{x}) = 32$

so once you have the SSTR then the MSTR is given by the following formula

$MSTR = \frac{SSTR}{t-1}$

where $t$ is the number of treatments, for this case the number of treatments is 3 so $t = 3$ and

$MSTR = \frac{32}{3-2} = \frac{32}{2} = 16$

Carson needs to purchase 5.6 meters if tape . If each roll contains 80 cm and cost $5 what if the total cost

SOVA2 [1]

Each roll contains 80cm which is the same as 0.8 meters. Because he needs 5.6 meters, divide 5.6 by 0.8 and you 7. The seven is the number of rolls of tape he will need to purchase. Each roll costs $5 so multiply 7 by 5 and you will see that Carson will need to spend $35 if he wants to get that much tape. Hope that helps!
