The function given possesses real roots:

x^3 – 1.7x^2 + 0.84x – 0·108

Using a precision of 1% of a root, find the estimates of all roots using the secant method. After finding a root, reduce the polynomial using polynomial reduction before finding the next root with the secant method.

After being created in a high-energy particle accelerator, a pi meson at rest has an average lifetime of 2.60 10-8 s. Traveling at a speed very close to the speed of light, a pi meson travels a distance of 110 m before decaying. How fast is it moving? (Enter your answer to four significant figures.)

A Compartment A holds helium at pressure 5 atm, and compartment B holds argon at pressure 10atm. the partition between the gases is removed and the gases are allowed to mix. The mole fraction of helium in the mixture is 0.40 and the total volume of both compartments is 30.0 L . Temperature of helium and argon before and after mixing was 500K. Find volume of compartment A and B.

Chris’s Florist Shop records all prepaid costs as assets and all revenue collected in advance as liabilities, and makes adjustments only at its fiscal year end, which is June 30^th. All of Chris’s purchases are for cash unless stated otherwise. The following information relates to Chris’s June 30, 2011 year end, its first year of operations.

1.         On July 2^nd, 2010, Chris purchased equipment for $12,000. The equipment is expected to have a useful life of 8 years.

2.         On August 1, 2010 a one-year insurance policy was purchased for $1,740.

3.         On February 1, 2011 a corporate customer paid $2,080 as full payment for a one year contract for fresh flowers to be delivered to its offices every Monday morning. At June 30, 21 of the required 52 deliveries had been completed.

4.         On July 2, 2010 Chris purchased enough supplies to last the entire first year of operations for $4,400. At June 30, 2011, Chris counted the supplies on hand and calculated the cost, which amounted to $1,035.

5.         On May 31, Chris borrows $20,000 from the bank to increase the amount of inventory and expand the business. The interest rate on the loan is 6% and requires monthly payments of interest on the first of each month. The principal is due in one year’s time. The first interest payment is due July 1.

6          Chris pays her store assistant on alternate Fridays. The last pay day in June was June 20^th and the first pay day after year end July is July 4^th. The assistant worked 30 hours during this period, of which 20 were in July, and the rest in June. The assistant earns $9.50 an hour.

7.         June 28^th is a busy day and Chris has to make deliveries to numerous customers. On July 5^th she reviews her June billings, and realizes that she made one large sale for $325 on June 30^th for flowers that were delivered, but for which no invoice was issued. The sale was to a regular customer who will pay promptly when the invoice is sent.

8.         Chris offers customers a coupon valued at $20 every ten floral arrangements that a customer buys. At June 30^th, she reviews her records and finds that 18 customers have purchased enough flowers to claim coupons. Chris records the cost of these coupons as “Coupon Expense” when the customer becomes entitled to them.

Your answer is partially correct. Try again. At the end of 2016, Metlock, Inc. has accounts receivable of $666,300 and an allowance for doubtful accounts of $24,740. On January 24, 2017, it is learned that the company’s receivable from Madonna Inc. is not collectible and therefore management authorizes a write-off of $4,398.

Two cars start from rest at a red stop light. When the light turns green, both cars accelerate forward. The blue car accelerates uniformly at a rate of 3.4 m/s² for 4.1 seconds. It then continues at a constant speed for 14.7 seconds, before applying the brakes such that the car’s speed decreases uniformly coming to rest 258.93 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the blue car comes to a stop.

1) How fast is the blue car going 2.5 seconds after it starts?

2)How fast is the blue car going 9 seconds after it starts?

3)How far does the blue car travel before its brakes are applied to slow down?

4)What is the acceleration of the blue car once the brakes are applied?

5) What is the total time the blue car is moving?

6)What is the acceleration of the yellow car?

Below are matched pair data consisting of driving test scores for a sample of 10 licensed drivers before and after they took an online traffic safety class. At a 0.05 significance level, use the sign test to test the claim that taking this online class affects driving test scores.

(a) What is the value of the test statistic used in this sign test?

(b) What is the critical value in this sign test?

(c) What is the correct conclusion of this sign test?

• There is not sufficient evidence to support the claim that the online class affects driving test scores.
• There is sufficient evidence to support the claim that the online class affects driving test scores.
• There is sufficient evidence to warrant rejection of the claim that the online class affects driving test scores.
• There is not sufficient evidence to warrant rejection of the claim that the online class affects driving test scores.

An industrial psychologist is concerned that recent round of layoffs at a plant might have affected the stress felt by employees who retained their positions. To measure whether the employees experienced a change in stress, the psychologist administered a stress measure to a sample of employees before and after the layoffs occurred. Below are the data from the psychologist’s study; higher numbers correspond to higher stress levels.

1. 1. What are the null and alternative hypotheses?
   2. State your critical value(s) using α = .05.  
   3. Compute the observed value of the test statistic.
   4. What is your decision regarding the null hypothesis (Reject or Fail to Reject the null hypothesis)?
   5. What is your conclusion in the context of the problem? (State your conclusion in terms of the alternative hypothesis (in words) because the alternative hypothesis is the research question we are interested in answering).
2. f. What is the 95% confidence interval?
