The standard error of the estimate of the mean is represented by the equation: σ√n Discuss what this equation means, using your own words and explain why we use it. Consider how it relates to the fact that we are making assumptions about the population and not just the sample.

We will abbreviate Malonic acid, CH2(CO2H)2 as H2M. Find the pH and concentrations of H2M, HM-, and M^2- in a) .1 M H2M b) .1 M NaHM c) .1 M Na2M

An employee of a small software company in Minneapolis bikes to work during the summer months. He can travel to work using one of three routes and wonders whether the average commute times (in minutes) differ between the three routes. He obtains the following data after traveling each route for one week.

Use Tukey’s HSD method at the 5% significance level to determine which routes' average times differ. (Round difference to 1 decimal place, confidence interval bounds to 2 decimal places, and p-values to 3.)

College is an investment. Tuition can range from $3,000 to $20,000 for a full-time student per semester. It seems like every year the cost continues to increase. It has been announced that the average tuition will increase by 5 percent each year for the next 4 years. To help students manage the cost of college, write a program that allows the students to input their full-time tuition cost per semester and then using a loop displays the projected semester tuition amount for the next 4 years.

Ex.

Enter the full-time student tuition per semester:
5000

• In 1 year, the tuition will be $5250.00
• In 2 years, the tuition will be $5512.50
• In 3 years, …
• In 4 years, …

when 10000

Enter the full-time student tuition per semester: - In 1 year, the tuition will be $10500.00.

-In 2 years, the tuition will be $11025.00.

In 3 years, the tuition will be $11576.25.

here is what i got

def main():

amount=5000.0

print('Enter the full-time student tuition per semester:')

for i in range(1,5):

amount=amount+(amount*0.05)

if i is 0:

print('- In '+str(i)+' year, the tuition will be $'+str((amount))+'.')

elif i is 5:

print('- In '+str(i)+' years, the tuition will be $'+str(round(amount, 2))+'2.')

else:

print('- In '+str(i)+' years, the tuition will be $'+str(round(amount,2))+'.')

The E. coli chromosome contains 4,639,221 bp.
(a) How many turns of the double helix must be unwound during replication of the E. coli chromosome?
(b) From the data in this chapter, how long would it take to replicate the E. coli chromosome at 37 °C if two replication forks proceeded from the origin? Assume replication occurs at a rate of 1,000 bp/s. Under some conditions E. coli cells can divide every 20 min. How might this be possible?
(c) In the replication of the E. coli chromosome, about how many Okazaki fragments would be formed? What factors guarantee that the numerous Okazaki fragments are assembled in the correct order in the new DNA?

QUESTION 14

1. 445 moles of NADH are produced by the Citric Acid Cycle (CAC). How many moles of glucose needed to be broken down during glycolysis in order to produce enough pyruvate for the CAC to produce this many moles of NADH?

   Note: Brock, a Biology of Microorganisms considers the synthesis of Acetyl-CoA to be part of the Citric Acid Cycle. This is different than what you may have learned in BIOL-151 where the Morris Book considers Acetyl Co-A Synthesis a seperate step. See page 89 of Brock for full details.

   Round your answer to one decimal place.

QUESTION 15

1. If 82 moles of ATP are produced by glycolysis, how many moles of glucose were broken down?

   For every molecule of glucose broken down, 2 molecules of ATP are generated.

QUESTION 16

1. NADH and FADH are produced by the Citric Acid Cycle (CAC) and these electron shuttles go on to the Electron Transport Chain (ETC). A mole of NADH will produce 3 moles of ATP from the ETC. A mole of FADH₂ will produce 2 moles of ATP from the electron transport chain. A single mole of pyruvate will produce 4 moles of NADH and 1 mole of FADH2 from the CAC. Therefore, every  14 moles of ATP came from 1 mole of pyruvate.

   Given:

   The ETC produced 78 moles of ATP from the products of the CAC.

   Find:

   How many moles of pyruvate entered the CAC?

   Note: Brock, a Biology of Microorganisms considers the synthesis of Acetyl CoA from Pyruvate to be part of the Citric Acid Cycle. This is different than what you may have learned in BIOL-151 where the Morris Book considers Acetyl Co-A Synthesis a separate step. See page 89 of Brock for full details.

   Round your answer to one decimal place.

Break-Even Sales Under Present and Proposed Conditions

Darby Company, operating at full capacity, sold 156,100 units at a price of $108 per unit during the current year. Its income statement is as follows:

The division of costs between variable and fixed is as follows:

Management is considering a plant expansion program for the following year that will permit an increase of $1,296,000 in yearly sales. The expansion will increase fixed costs by $172,800, but will not affect the relationship between sales and variable costs.

Required:

1. Determine the total variable costs and the total fixed costs for the current year.

2. Determine (a) the unit variable cost and (b) the unit contribution margin for the current year.

3. Compute the break-even sales (units) for the current year.
units

4. Compute the break-even sales (units) under the proposed program for the following year.
units

5. Determine the amount of sales (units) that would be necessary under the proposed program to realize the $6,094,800 of income from operations that was earned in the current year.
units

6. Determine the maximum income from operations possible with the expanded plant.
$

7. If the proposal is accepted and sales remain at the current level, what will the income or loss from operations be for the following year?
$

8. Based on the data given, would you recommend accepting the proposal?

1. In favor of the proposal because of the reduction in break-even point.
2. In favor of the proposal because of the possibility of increasing income from operations.
3. In favor of the proposal because of the increase in break-even point.
4. Reject the proposal because if future sales remain at the current level, the income from operations will increase.
5. Reject the proposal because the sales necessary to maintain the current income from operations would be below the current year sales.

Choose the correct answer.
