Can you please explain the following thoroughly:

Is anything 100% safe or 100% foolproof? (from any perspective such as the drug approval process at the FDA, airline safety, new products, or the prospects for economic growth)

Maize Plastics manufactures and sells 100 100 bottles per day. Fixed costs are $ 22 comma 000 $22,000 and the variable costs for manufacturing 100 100 bottles are $ 50 comma 000 $50,000. Each bottle is sold for $ 1 comma 300 $1,300. How would the daily profit be affected if the daily volume of sales drop by 10 10​%?

The t statistic is -2.15 . The P-value for the statistic falls between _ and _.

A 100 g bullet traveling in the x-direction at 100 m/s strikes a 1 kg wooden block at
rest. After the collision, wooden block splits into two parts [.2 kg and .8 kg] and the
bullet is observed traveling at a speed of 50 m/s in the x-direction. Assume that the
wooden pieces are traveling in the x-y plane and the .8 kg piece is traveling 30 degrees to the
right of the x-direction. If the kinetic energies of the wooden pieces are equal after the
collision,
i) In which direction is the .2 kg piece moving?
ii) What are the velocities of the two wooden pieces?
iii) How much kinetic energy is lost during the collision?

Medical Terminology: ( Case Study)

Building a Medical Vocabulary:

Pick 100 medical terms (NOT 100 words) that you learned in class and create a case study ( I got some information about my case study and I need your help to complete: Lessons Learned), in the end, I put an example for what I want.

these my first points of case study, and I need the other point (Lessons Learned):

Introduction

A 59 year of Male patient reported to the XYL clinic with a complaint of pain in the right ear region. The pain is a Throbbing kind which increases on changing position to supine. There has also been a restriction in mandibular movement which has lead to a decrease in appetite of the patient. Swelling along with tenderness on percussion seen in the right side of the face, in the ear region, on touching. The patient also experienced mild Hyperthermia in the morning, for which he took an anti-pyretic and an analgesic for the pain, which is Tab Paracetamol and Tab Diclofenac Sodium.

Patient history/Medical history

The patient has a history of type 2 Diabetes mellitus, for which he was diagnosed 15 years ago.He has been taking Tab Metformin twice daily before food, per orally. Patient also suffers from occational migraineattacks for which he takes, Tab Tramadol, which has been prescribed to him by his neurologist.His Body Mass Index is lower than normal, at 17.5, for which he has been consulting a Nutritionalist, for the treatment for muscular atrophy. Patient has recently taken retirement from work, which has lead him to depression due to lack of company, work and boredom.

Family History-

Patients mother passed away two years ago due to celebral haemorrhage and his father passed away a year ago due to a long standing diabetic foot ulcer, eventually succumbing to stroke. Bother mother and father also have a history of Hypertension.

ASSESSMENT RESULTS

Based on GCS,the patient remained conscious and oriented and cooperative. He sits by the side of his bed during examination but has difficulty talking due to pain, but no trismus. He is lean and undernourished probably due chronic diabetes, there are signs of muscle atrophy. Mild pallor seen on examination of bulbar conjunctiva and mucosa of oral cavity. Pulse - 78 per minute, normal rhythm, volume in radial artery and normal character in carotid artery . Blood pressure normal and temperature normal at the time of examination. On oral examination, the oral hygiene is poor, oral ulcers on the right mucosa. Third molar partially impacted, other teeth in place and no caries. Patient on regular follow up for diabetes and on regular medication. No foot ulcers and he is taking good foot care. He complains of floaters and blurred vision. He sits alone for long hours and has panic attacks and this has aggravated his head ache during the past month. Also complains of photophobia.

ACTIONS TAKEN

Dental x- ray taken intraorally and confirmed the findings of oral examination. Right third molar partially impacted with peri-apical abscess. Blood taken for routine and HbA1c(glycated hemoglobin)- the value came out as 8- slightly higher than the normal(6.5g%). Hyperglycemia in fasting blood glucose test , poor glycemic control Diabetic neuropathy and nephropathy ruled out. Renal function test came out normal. Ophthalmologicexamination reveals diabetic retinopathy. He is referred to ophthalmologist for further check up. He is referred to a psychiatrist for his panic attacks and depression.

RESULTS

Diagnosis of partial impaction of third molar seen on the right side along with peri-apical abscess leading to pain and swelling, was made by oral and radiologic examination. Followed up after a week and his symptoms subsided, pain reduced and swelling gone. The impacted tooth was removed by the dentist. Followed up monthly for diabetes and after ophthalmologic consultation, he has improvement in vision. Followed up monthly by psychiatrist and his wife admits that he has become more socially active and has joined the story teller's club in his town to make active use of his time. This is an example of a case study: Lessons Learned: Teachings from this case study presented information of medications that are typically prescribed for diabetics. Additionally, it was helpful to understand appropriate ranges of glycosylated hemoglobin for diabetics and that patients need critical exams. Two main ones are annual eye and foot exams. Uncontrolled 13. diabetes compromises nerves in the eyes and lower extremities first. If patients dismiss annual examinations, they can have eye complications and 36. necrosis of the feet if wounds are left unchecked. Psychological well-being also carries weight when working with patients and their families. Complex information is thrown around and the time to process is different from medical professionals, so giving them time to formulate thoughts and questions will ease confusion, misunderstanding, or even misdiagnosis and treatment (Tx) routes needed. The likelihood of developing psychological disorders or symptoms are common. Overall, maintaining good practices for boundaries as well as compassion is always a big take away.

A 685-liter oxygen tank contains oxygen gas at 20℃ . When the tank is full, the pressure gauge reads 3000 psi. a. How many oxygen molecules are in the cylinder? b. What is the number density of the oxygen? c. How much does the oxygen in the tank weigh?

A 3-year project requires an initial investment of $100 million (CF0=-100), and will return
cash infows of $70 million, $50 million, and $20 million at the end of the years 1, 2, and
3, respectively. Assuming a weighted average cost of capital of 10%, what is the discounted
payback period for this project?
