Hello!
Throughout this problem, we will add or subtract values from our original balance.
In your checkbook, there was 298.72 dollars, and then you deposited 425.69 dollars. The function you would do is addition.
$298.72 + 425.69 = $724.41
If you wrote a check, then the amount you wrote is removed from your checkbook.
$724.41 - $29.72 - $135.47- $208.28 = $350.94
Then, the bank deducted 5 dollars from your account.
$350.94 - $5.00 = $345.94
This leaves you with $345.94 at the end of the week.
Therefore, your answer is choice C, $345.94.
The answer choice which represents the solution to the inequality as given in the task content is; x>-2 or x≤ 1.
<h3>What is the solution of the give complex inequality?</h3>
On this note, it follows that the inequalities can be solved individually as follows;
-4 < 3x +2
-6 < 3x
x > -2
Also, 3x +2 ≤ 5
3x ≤ 3
x ≤ 1.
Ultimately, the correct answer choice is; Choice C; x>-2 or x≤ 1.

Answer:
d. t distribution with df = 80
Step-by-step explanation:
Assuming this problem:
Consider independent simple random samples that are taken to test the difference between the means of two populations. The variances of the populations are unknown, but are assumed to be equal. The sample sizes of each population are n1 = 37 and n2 = 45. The appropriate distribution to use is the:
a. t distribution with df = 82.
b. t distribution with df = 81.
c. t distribution with df = 41.
d. t distribution with df = 80
Solution to the problem
When we have two independent samples from two normal distributions with equal variances we are assuming that
And the statistic is given by this formula:
Where t follows a t distribution with 
degrees of freedom and the pooled variance 
is given by this formula:
This last one is an unbiased estimator of the common variance 
So on this case the degrees of freedom are given by:
And the best answer is:
d. t distribution with df = 80
