It should be no mystery that amounts deposited get added to bank balance, and amounts withdrawn by any means get subtracted. Regarding the balance in the bank, a debit card withdrawal is equivalent to a cheque withdrawal.

Regarding the balance in the bank, a debit card withdrawal is equivalent to a cheque withdrawal. The debit card withdrawal differs from a check in the check register in that there is no check number (and frequently no transaction number) connected to it.

initial transaction

$100 is deposited to open the account. The starting balance is that sum.

two-way transaction

You must calculate the tax on the purchases for this issue. Normally, the store would take care of that for you, and you would write a check to cover the debt. The sum owed in this case is...

Rounding up from $43.82 to 45.5728 is 45.57.

Instead of calculating the tax individually and then adding it to the original amount, it is more convenient to use a multiplier to determine the amount with tax. You should be aware that the purchase price multiplied by 100% plus 4% equals 104%, or 1.04 times the price.

As a withdrawal, this $45.57 is deducted from the prior transaction's $100 total, resulting in a new balance of $54.43.

third action

This is a straightforward withdrawal, therefore $46.43 is obtained by deducting the sum from the prior balance.

As previously said, there is no transaction number connected to this. It can occasionally be helpful to keep track of which debit card is being used if you have several debit cards that are taking money out of the account. The final four digits of the card number are used to identify transactions on my bank statement.

Fourth action

You must calculate the payroll deposit amount for this problem. That would typically be handled for you by your employer, along with any deductions for taxes, insurance, union dues, or employee purchases. The sum deposited in this case is...

Hourly rate times 40 equals $9.75, which equals $390.

The previous value is increased by this deposit, making the new balance $436.43.

In most cases, the coupon is applied to transactions including coupons before the tax is calculated. The fact that the purchase amounts are combined should be obvious. (You can calculate the total when there are numerous items at the same price using repeated addition or multiplication; most people find multiplication to be simpler.)

The purchase from the bike shop is arguably the most difficult. The total of the values in brackets is...

$180.00 + 14.95 + 8.95 = 203.90

Then, the 15% discount is applied.

Rounding up to 30.59 from 0.15 x $203.90 = 30.585

Taking this out of the previous amount* yields (before taxes)...

$203.90 -30.59 = $173.31

The amount subject to tax can then be calculated using the same multiplier described above:

Round to $180.24 using the formula: amount with tax = $173.31 x 1.04 = $180.24

* Talk about the 15% discount

As with additional tax, you can calculate the discount using a multiplier:

100% - 15% = 85% . . . 0.85 times as much

The result of applying this multiplier to the number 203.90 is 173.315, which is typically rounded up to 173.32. But this figure results from a discount that is rounded to the nearest half cent (30.585). The discounted amount, 173.315, is rounded down to 173.31 if the discount is rounded up. The intricacy of applying a multiplier to discounts is there.

Answer:

b=1.25r+6.25 and for R =-4b/5+5

Step-by-step explanation:

b=1.25r+6.25 and for R =-4b/5+5

Answer:

r = 1

b = 6.25

Step-by-step explanation:

We can use the given equation to solve for one of the variables in terms of the other, and then substitute that expression into the equation to solve for the other variable.

Starting with the equation:

1.6b + 2r = 10

Subtracting 2r from both sides, we get:

1.6b = 10 - 2r

Dividing both sides by 1.6, we get:

b = (10 - 2r) / 1.6

Now we can substitute this expression for b into the original equation:

1.6b + 2r = 10

1.6[(10 - 2r) / 1.6] + 2r = 10

Simplifying, we get:

10 - 2r + 2r = 10

So, the equation is true for any value of r. Therefore, r can be any number.

To find b, we can use the expression we found earlier:

b = (10 - 2r) / 1.6

For example, if we set r = 1, then:

b = (10 - 2(1)) / 1.6 = 6.25

Therefore, when r = 1, b = 6.25.

The result will provide the test statistic and the p-value. If the p-value is less than 0.05, we would conclude that the normality assumption is violated.

a. To create a data frame called "turkey" with the first column as "Diet" and the second column as "EggWeights," you can use the following code in R:

R

Copy code

Diet <- c(rep("A", 5), rep("B", 5), rep("C", 5))

EggWeights <- c(124, 118, 120, 127, 115, 98, 100, 95, 102, 105, 116, 97, 100, 89, 98)

turkey <- data.frame(Diet, EggWeights)

b. To test the normality assumption using the Shapiro-Wilk test, you can use the following code:

R

Copy code

shapiro.test(turkey$EggWeights)

c. The normality assumption is violated if the p-value from the Shapiro-Wilk test is less than the significance level (typically 0.05). If the p-value is greater than 0.05, we fail to reject the null hypothesis of normality.

Based on the provided data, the Shapiro-Wilk test can be performed in R:

R

Copy code

shapiro.test(turkey$EggWeights)

The result will provide the test statistic and the p-value. If the p-value is less than 0.05, we would conclude that the normality assumption is violated. If the p-value is greater than 0.05, we would fail to reject the null hypothesis and conclude that the data are consistent with normality.

Note: Since the provided data is relatively small, the Shapiro-Wilk test may not have high power to detect departures from normality. However, it can still provide some insight into the normality assumption.

Yes, it is appropriate to use the methods of hypothesis testing to test the proportion of allergy sufferers who experience relief from the new allergy medication.

The methods of hypothesis testing can be used to test any hypothesis about a population parameter, provided certain assumptions are met. In this case, we want to test a hypothesis about the proportion of allergy sufferers who experience relief from the medication, which is a population parameter.

To perform a hypothesis test, we need to have a random sample from the population, which is given in the problem statement. We also need to check the assumptions that the sample is representative of the population, and the observations are independent.

What is hypothesis?

A hypothesis is a statement or assumption about a population parameter, such as a population mean or proportion.

The probability that the proportion of overweight or obese children in the sample will be greater than 0.57 is less than 50%.

The first paragraph summarizes the answer, stating that the probability is less than 50% because 0.57 is less than the population proportion of 0.60, and the sampling distribution is approximately normal.

In the second paragraph, we can explain the reasoning behind this conclusion. The Central Limit Theorem states that for a large sample size, the sampling distribution of the sample proportion will be approximately normal, regardless of the shape of the population distribution. In this case, the sample was taken in a way that meets the conditions for using the Central Limit Theorem.

Since the population proportion of overweight or obese children is 0.60, any sample proportion below this value is more likely to occur. Therefore, the probability of obtaining a sample proportion greater than 0.57 would be less than 50%. This is because the resulting z-score, which measures how many standard deviations the sample proportion is away from the population proportion, would be negative.

To summarize, the probability of the proportion of overweight or obese children in the sample being greater than 0.57 is less than 50% because 0.57 is less than the population proportion of 0.60, and the sampling distribution is approximately normal.

The pieces of cloth are beyond the standard at 0.05 level of significance.

We can use a one-sample t-test to determine if the mean length of the 35 pieces of cloth is significantly different from the standard length of 3.25 meters.

The null hypothesis is that the mean length of the cloth pieces is equal to the standard length:

H0: μ = 3.25

The alternative hypothesis is that the mean length of the cloth pieces is greater than the standard length:

Ha: μ > 3.25

We can calculate the test statistic as:

t = (x - μ) / (s / √n)

where x is the sample mean length, μ is the population mean length (3.25 meters), s is the sample standard deviation (0.52 meters), and n is the sample size (35).

Plugging in the values, we get:

t = (3.52 - 3.25) / (0.52 / √35) = 3.81

Using a t-table with 34 degrees of freedom (n-1), and a significance level of 0.05 (one-tailed test), the critical t-value is 1.690.

Since our calculated t-value (3.81) is greater than the critical t-value (1.690), we reject the null hypothesis and conclude that the mean length of the 35 pieces of cloth is significantly greater than the standard length at the 0.05 level of significance.
