IRINA_888 [86]

The combination that could be the total sales would be 360 tablets and 180 computers.

<h3>Total sales</h3>

Over 300 total sales were made in January

100 tablets and 20 computers were sold in February.

This means that total sales would be: (300+) 100 + 20 = 420+

Only options B and C have 420+ total sales.

But, there are more tablet sales than computers.

Thus, we are left with only option B

Serum cholesterol levels of 100 hypertensive patients were recorded. Mean cholesterol level was 190 mg/d1. The data was symmetri

xxTIMURxx [149]

The standard error is 1.5.

The range of 95% confidence interval is 160 mg/dL and 220 mg/dL

<h3>What is the standard error of the distribution?</h3>

The standard error of the distribution is calculated as follows:

Standard error = standard deviation/√N

where N is the number of participants = 100

From the empirical rule of a normal or symmetrical distribution;

68% of the data lies within one standard deviation
95% percent within two standard deviations, and
99.7% within three standard deviations from the mean.

Therefore, 175 mg/dl and 205 mg/dl lie one standard deviation from the mean.

One standard deviation = 175 - 190 or 205 - 190 = ±15

Standard deviation = 15

a. Solving for the standard error using the equation above;

Standard error = 15/√100

Standard error = 1.5

b. The range of 95% confidence interval is two standard deviations away from the mean.

Range of values two standard deviations from the mean = 190 - (2*15) and 190 + (2 * 15)

Range of values two standard deviations from the mean = 160 mg/dL and 220 mg/dL

Therefore, the range of 95% confidence interval is 160 mg/dL and 220 mg/dL

In conclusion, the standard error is calculated from the standard deviation and the sample size.

Zigmanuir [339]

The break-even point is closest to $50,846.

Let understand that the break-even point refers to the point where the total revenue equals the total costs.

Below are steps to help us derive the break-even point.

Particulars R38T X08S Total

Sales $20,000 $39,000 $59,000

Variable costs <u>$7,400 </u> <u>$6,170 </u> <u>$13,570</u>

Contribution margin <u>$12,600 </u> <u>$32,830</u> <u>$45,430</u>

Total Contribution margin ratio = Total Contribution / Total Sales

Total Contribution margin ratio = $33,150 / $51,000

Total Contribution margin ratio = 0.65

Total Contribution margin ratio = 65%

Break even point = Fixed costs / Contribution margin ratio

Break even point = $33,050 / 0.65

Break even point = $50,846

In conclusion, the break-even point for the entire company is closest to $50,846.
