Depreciation Once a new car is driven away from the dealer, it begins to lose value. Each year, a car loses 10% of its value. This means that each year the value of a car is 90% of the previous year’s value. If a new car was purchased for $20,000, the value at the end of the first year would be $20000(0.90) and the value of the car after the end of the second year would be $20000(0.90)2. Complete the table shown below. What will be the value of the car at the end of the eighth year? Simplify the expression, to show the value in dollars.
During one the nurse’s hourly assessments, Ana is lethargic, her respirations are 8/minute and her DTRs are absent. The nurse identifies this as magnesium sulfate toxicity and after informing the obstetrician the following is ordered: stat magnesium level, stop the magnesium infusion, calcium gluconate, 1 gm IVP over 3 mins. One hour later her magnesium level is 7 mg , therapeutic for preeclampsia (4.7 to 8 mg/dl). The nurse evaluates the intervention. The patient has normal CNS functioning; is alert and oriented; respiratory rate is 16; DTR 2+, and urine output 75 mL so the magnesium sulfate is restarted at 1 g/hr per provider order. With the same solution of 40 g/liter, at what rate (mL/hr) would the nurse set the infusion pump?

Byron is conducting an experiment to determine whether a new medication is effective in reducing coughing. He finds 1,200 volunteers with coughing issues and divides them into two groups. The control group does not receive any medication; the treatment group receives the medication. The patients in the treatment group show reduced signs of coughing. What can Byron conclude from this experiment?
Baby Sofia is 6 months old. Her father takes her to her medical appointment at his neighbourhood family clinic. After Sofia is measured, her father is informed that she measures 68 cm, like 5 other babies who visit this clinic. In addition, he is told that 40 babies are bigger than her and that a total of 185 babies are being followed at the clinic. m What is Sofia's percentile rank at this clinic in relation to her height?
You are an epidemiologist and have been alerted to an outbreak of gastrointestinal disease. Nearly all ill persons reported attending the pancake breakfast. You interview the 157 people who attended the pancake breakfast. 102 people reported eating pancakes; 37 of those reported illness. Of those who did not eat pancakes, 24 reported illness. Calculate the attack rate for those who ate pancakes. Round to the nearest whole number and do not include any symbols.
In general, ___________% of the values in a data set lie at or below the 28 th percentile. _______________ % of the values in a data set lie at or above the 90 th percentile.. If a sample consists of 700 test scores, _________of them would be at or below the 52 th percentile. If a sample consists of 700 test scores, ________ of them would be at or above the 64 th percentile.
Answer quickly please. Need answer ASAP. In a winter of an epidemic fu, the parents of 2000 babies were surveyed by researchers at a well-known pharmaceutical company to determine if the company's new medicine was effective after two days. Among 120 babies who had the fu and were given the medicine, 29 were cured within two days. Among 280 babies who had the flu but were not given the medicine, 56 recovered within two days. Is there any significant indication that supports the company's claim of the effectiveness of the medicine? Use α = 0.01
A 2009 study showed that handling money reduces the perception of pain. Two groups ofparticipants were asked to participate in a manual dexterity study. Half of the participantswere given a stack of money to count and the other half were given a stack of blankpieces of paper to count. After the counting task, the participants were asked to dip theirhands into bowls of very hot water (122 degrees Fahrenheit) and rate how uncomfortableit was. The following data show ratings of pain similar to the results obtained in thestudy.Counting Money Counting Paper7 98 1110 136 108 115 97 1512 145 10?1 = 7.56 ?2 = 11.33SS = 42.22 SS = 38a.

As humans we consume food. The body extracts good things such as proteins and vitamins and throws away waste. A typical waste product is uric acid. High levels of uric acid can be an indication of conditions such as gout, kidney disease, and cancer. For females a high level of uric acid is 6 mg/dL or more and for males a high level of uric acid is 7 mg/dL or more. Suppose, over a period of months, an adult male was given 9 blood tests for uric acid. The results of each blood test are shown below. results 10.24 10.1 11.19 11.1 9.34 9.58 9.63 10.59 9.58 The distribution of uric acid in healthy adult males is normally distributed with known population standard deviation, σ=1.15σ=1.15 mg/dl.Find a 95% confidence interval for the population mean of uric acid in this adult male's blood.
