Answer:

B and D

Step-by-step explanation:

Geometric sequences and series. A geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio, r.

an = ar^(n-1)

d) 1/3, 2/3, 4/3, 8/3, 16/3, . . . .

1/3 * 2 = 2/3

2/3 * 2 = 4/3

4/3 * 2 = 8/3

where r = 2, constant multiplier is 2.  //Answer

b)  320, 80, 20, 5, 1.25, . . . . .

320 * 1/4 = 80

80 * 1/4 = 20

20 * 1/4 = 5

r = 1/4 //Answer

Answer: B and D

//Hope this helps.

Find the second, fourth, and eleventh terms of the
tekilochka [14]

Answer:

The second term is -6 , the fourth term is 0 , the eleventh term is 21

Step-by-step explanation:

* Lets revise the explicit formula

- An explicit formula will create a sequence using n, the number

 position of each term.

- If you can find an explicit formula for a sequence, you will be able

 to quickly and easily find any term in the sequence by replacing

 n with the number of the term you want

- It defines the sequence as a formula in terms of n.

* Now lets solve the problem

- The formula of the sequence is A(n) = -9 + (n - 1)(3)

- A(n) is any term in the sequence

- n is the position of the number

- To find the second term put n = 2

∵ n = 2

∴ A(2) = -9 + (2 - 1)(3) = -9 + (1)(3) = -9 + 3 = -6

* The second term is -6

- To find the fourth term put n = 4

∵ n = 4

∴ A(4) = -9 + (4 - 1)(3) = -9 + (3)(3) = -9 + 9 = 0

* The fourth term is 0

- To find the eleventh term put n = 11

∵ n = 11

∴ A(11) = -9 + (11 - 1)(3) = -9 + (10)(3) = -9 + 30 = 21

* The eleventh term is 21

PLEASE HELP WILL MARK BRAINLIEST AND GIVE 50 POINTS
Alexeev081 [22]

Answer:

The correct option is;

e. 2500

Step-by-step explanation:

The formula for sample size is given by the following formula;

n = \dfrac{z^2 \times \hat p(1 - \hat p)}{\epsilon ^2}

At 95%, z = 1.96

ε = Margin of error = 0.02 = 2%

Finding the sample size, n, given only the margin of error is by the following formula;

Margin of error = 100/√n

Therefore, we have;

2 = 100/√n

√n = 100/2 = 50

n = 50² = 2500

Therefore, the correct option is e. 2500.

JulsSmile [24]

a) The preparation of the bank reconciliation statement on August 31 for Cullumber Company is as follows:

<h3>Bank Reconciliation Statement</h3>

Balance as per bank statement            $16,780

Add uncredited deposits of 17,220

       Check #705 overstated                         36

Less uncashed checks                            (5,780)

Adjusted bank statement balance of $28,256

b) The preparation of the necessary adjusting entries on August 31 is as follows:

Debit Cash $2,050

Credit Accounts Receivable (EFT deposits) $2,050

Debit Accounts Receivable (R. Dubai) $197

Credit NSF charges $187

Credit Service charges $10

Debit Bank service charges $27

Credit Cash $27

<h3>What is bank reconciliation?</h3>

Bank reconciliation is the comparison of an entity's records with those of its bank, to uncover any differences between these two sets of records of bank transactions.

Bank reconciliation is carried out by the preparation of a bank reconciliation statement, which outlines the deposits, withdrawals, and other activities affecting a bank account for a specific period.

<h3>Data and Calculations:</h3>

Cash balance per books on August 31, 2021 = $26,420

Bank statement balance = $16,780

<h3>Analysis of Discrepancies:</h3>

1. Uncredited deposit = $17,220

2. EFT deposits = $2,050

3. Outstanding checks:
Check #673 = $1,230

Check #710 = $2,330

Check #712 = $2,220

Total outstanding checks = $5,780 ($1,230 + $2,330 + $2,220)

4. NSF charge = $187

Service charge = $10

5. Bank service charges = $27

6. Check #705 overstated = $36 ($173 - $137)

<h3>Adjusted Cash Account:</h3>

Balance as per Cash Book        $26,420

EFT deposits                                $2,050

Less:

NSF charge                 187

Bank service charges 27                (214)

Adjusted cash book balance $28,256

Triangle abc is isosceles. Solve for the length of the line segment connecting the midpoints of the two sides of equal length. A
Arada [10]
From the given triangle, midpoint of AB = ((-2 + 3)/2, (0 + 6)/2) = (1/2, 3) and the midpoint of BC = ((3 + 8)/2, (6 + 0)/2) = (11/2, 3)
Length of the line segment joining points (1/2, 3) and (11/2, 3) is given by
l = sqrt[(11/2 - 1/2)^2 + (3 - 3)^2] = sqrt(5^2) = 5.

Therefore, option A is the correct answer.
