What should the balance be in Arianna register? Use this bank statement
A.-$32.63
B.$448.72
C.$587.88
D.877.82
Answer:
Step-by-step explanation:
Observe in the attached image that the final balance in your account on 9/1 is $578.30.
Then:
*On 9/6 he makes a payment of $140.30
*On 9/8, he makes a withdrawal from an ATM of $120
This means that:
$140.30 + $120 = $260.30
Then:
*On 9/18 you receive a deposit of $356.22
This means that:
$356.22
So, we have:
Beginning Balance: $578.30.
Total Withdrawals: $260.30
Total Deposits: $356.22
Final Balance = Beginning balance + Total Deposits - Total Withdrawals
Final Balance= $578.30 + $356.22 - $260.30
Final balance= $674.22
Then:
Date Description Debits(-) Credits(+) Balance
9/6 Auto Pay 140.30 438.00
9/8 ATM 120.0 318.00
9/18 Deposit 356.22 674.22
The balance in Arianna's register after the transactions will be $587.88. Then the correct option is C.
What is a bank transaction?
A monetary transfer is a record of money entering and exiting your account and is known as a bank transaction.
Arianna's register shows a deposit on 9/5 in the amount of $310.25 an ATM withdrawal on 9/8 in the amount of $60.00 and checks #149 on 9/14 in the amount of $240.67.
No other Transactions were made.
Then the balance be in Arianna's register will be
→ $ 578.37 + $ 310.25 - $ 60 - $ 240.67
→ $ 587.88

I would say that the study reveals that there may be a correlation between eating blueberries and a lower cholesterol level.
The best conclusion from the study is that the consumption of blueberries might be associated with lower cholesterol levels. However, it's important to note that correlation does not mean causation and other factors could be at play.
Explanation:The statement that comes closest to an appropriate conclusion from the study is that the possible consumption of blueberries might be associated with lower cholesterol levels. However, it is important to remember that correlation does not necessarily imply causation. While the organization of farmers showed a connection between eating blueberries and lower cholesterol, this does not necessarily mean eating blueberries directly causes lower cholesterol. Other factors could be involved. For instance, those who eat blueberries daily might generally lead healthier lifestyles, contributing to lower cholesterol levels.

The selection of "Yes" or "No" to state whether each data set is likely to be normally distributed is as follows: A) No. B) Yes. C) Yes. D) No
1. The number of coupons used at a supermarket is likely to follow a discrete distribution rather than a normal distribution. Customers may use 0, 1, 2, or more coupons, but the number of coupons used is not continuous and typically has a lower bound of 0. The distribution may be skewed to the right with a large number of transactions involving no coupons and a decreasing frequency as the number of coupons increases.
2. The weights of pumpkins are likely to be normally distributed because they are a result of many different factors, such as genetics, soil quality, water intake, etc., which tend to produce a bell-shaped curve when combined. This is an example of a continuous measurement that can be modeled well with a normal distribution.
3. The number of raisins in each 8-oz box is likely to be normally distributed due to the central limit theorem. Although the distribution of raisins per box might be uniform or have some other distribution, when the sample size (number of raisins per box) is large, the distribution of the sample mean (total number of raisins in many boxes) will approach a normal distribution. Since an 8-oz box contains a large number of raisins, the count in each box should be approximately normal.
4. The amount of time customers spend waiting in the checkout line is likely not to be normally distributed. This is because the waiting time is bounded below by zero and may have an upper limit depending on the store's operating hours or customer patience. The distribution of waiting times is often skewed to the right, with many customers experiencing short waits and a few experiencing longer waits. This results in a distribution with a long tail on the right side, which is not characteristic of a normal distribution.

Answer:
81.75 ft²
Step-by-step explanation:
The area (A) of a trapezoid is calculated using the formula
A = [tex]\frac{1}{2}[/tex] h (a + b)
where a, b are the parallel bases and h is the perpendicular height
Calculate h using the right triangle and the sine ratio
sin30° = [tex]\frac{opposite }{hypotenuse}[/tex] = [tex]\frac{h}{10}[/tex]
Multiply both sides by 10
10 × sin30° = h, thus
h = 5
a = 12 and b = 8.7 + 12 = 20.7, hence
A = [tex]\frac{1}{2}[/tex] × 5 × (12 + 20.7)
= 0.5 × 5 ×32.7

Find the period of the function. y=3 sin x/8
Answer:
The period of given function is [tex]Period = 16\pi [/tex]
So, Option B is correct.
Step-by-step explanation:
In this question we need to find the period of the function y= 3 sin x/8
The formula used to find period of function is: [tex]\frac{2\pi }{b}[/tex]
We need to know the value of b.
To find the value of b we compare the standard equation with the equation of function given.
Standard Equation: y = a sin(bx - c) +d
Given Equation: y= 3 sin(x/8)
Comparing we get:
a= 3
b= 1/8
c= 0
d=0
So, we get the value of b i.e 1/8. Putting it in the formula to find period of given function.
[tex]Period = \frac{2\pi }{b}[/tex]
[tex]Period = \frac{2\pi }{\frac{1}{8}}[/tex]
Solving,
[tex]Period = 2\pi *8[/tex]
[tex]Period = 16\pi [/tex]
So, the period of given function is [tex]Period = 16\pi [/tex]

Let f(x)= cos(2x) +e^(-x). for what value of x on the interval (0,3) will f have the same instantaneous rate of change as the average rate of change of f over the interval?
[tex]f(x)[/tex] is continuous on [0, 3] and differentiable on (0, 3), so the mean value theorem applies here. It says that there is some [tex]c[/tex] in the open interval (0, 3) such that

725 > 670; therefore, the mean is greater than the median.
a toy company's total payment salaries for the first two months of 2005 is $21, 894. write and solve an equation to find the salaries for the second month if the first month's salaries are $10,205.
Solution: Second month = m
The equation is
m + 10205 = 21894
m = 11689
So the second month will be $11,894. :)
To solve for the second month's salaries, subtract the first month salary from the total for two months. The solution to the equation $21,894 - $10,205 gives this salary: $11,689.
Explanation:The subject of this problem is a toy company's salary expenses over a course of two months. Let's denote the salary expenses for the second month as X. We know from the problem that the total salary expenses for the first two months (January and February) are $21,894. Furthermore, we know that the salary expenses for January are $10,205.
We can write an equation to express these facts as follows: X (which is the salary expenses for February) is equal to the total salary for the two months minus the salary for January, or in mathematical notation, X = $21,894 - $10,205.
We solve this math equation by subtracting $10,205 from $21,894, giving us X = $11,689. Therefore, the second month's salaries total $11,689.

If a certain negative number is multiplied by six, the result is the same as 20 less than the original number. What is the value of the original number?
The original negative number in the problem is found by setting up the equation 6x = x - 20 and solving for x, which results in the original number being -4.
Explanation:If a certain negative number is multiplied by six, the result is the same as 20 less than the original number. To solve for the original number, we can set up an equation based on the given condition. Let's assume the original number is x.
According to the problem, 6 times x equals x subtracted by 20:
6x = x - 20
To solve for x, we'll first move all terms involving x to one side of the equation by subtracting x from both sides:
6x - x = -20
This simplifies to:
5x = -20
Now, divide both sides by 5 to isolate x:
x = -20/5
x = -4
Therefore, the value of the original number is -4.
