please help me A portion of Taquan's check register is shown. Before Taquan made his utility payment on March 24, the balance of

Natalka [10]

The check register is used to show the total amount Taquan spent

Using the assumed values, Taquan's initial balance is $1336.26

<h3>How to determine the amount before making the utility payment?</h3>

The question is incomplete, as the check register is not shown.

So, I will give a general explanation

Assume that the utility bill is $241.46

From the question, the new balance on March 24 is $1094.80

This means that the initial balance is:

Initial balance = New balance + Utility bill

This gives

Initial balance = $1094.80 + $241.46

Evaluate the sum

Initial balance = $1336.26

Using the assumed values, Taquan's initial balance is $1336.26

Step-by-step explanation:

We have to make the dogs art of the ratio equal first.

5:3>30:18

6:1> 180: 30

After this we have to simplify the ratio.

Cats to fish is 180:18 (divide by 2) 90:9 (then by 3) 30 : 3 (and finally by 3 again) 10 : 1

At a peace summit, seven Hatfield and nine McCoy family

katrin2010 [14]

Answer:

0.525 = 52.5% probability that the two are from different families.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, the order in which the two participants are selected is not important, so we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Desired outcomes:

1 from the Harfield family(from a set of 7).

1 from the McCoy family(from a set of 9). So

$D = C_{7,1}*C_{9,1} = \frac{7!}{1!6!}*\frac{9!}{1!8!} = 7*9 = 63$

Total outcomes:

2 from a set of 16. So

$T = C_{16,2} = \frac{16!}{2!14!} = 120$

Probability:

$p = \frac{D}{T} = \frac{63}{120} = 0.525$

0.525 = 52.5% probability that the two are from different families.
