Answers
Answer:
x = 22.6°
y = 12
Step-by-step explanation:
✔️Find x using trigonometric ratio formula:
Reference angle = x
Opposite side to x = 5
Hypotenuse = 13
Thus:
[tex] sin(x) = \frac{5}{13} [/tex]
[tex] x = sin^{-1}(\frac{5}{13}) [/tex]
[tex] x = 22.6 degrees [/tex] (nearest tenth)
✔️Find y using Pythagorean Theorem:
Thus:
y² = 13² - 5²
y² = 144
y = √144
y = 12

Are anesthetics safe? The National Halothane Study was a major investigation of the safety of anesthetics used in surgery. Records of over 850,000 operations performed in 34 major hospitals showed the following death rates for four common anesthetics:
Anesthetic A B C D
Death 1.7% 1.7% 3.4% 1.9%
There seems to be a dear association between the anesthetic used and the death rate of patients. Anesthetic C appears to be dangerous.
A) Select the best explanation for why we call the National Halothane Study an observational study rather than an experiment, even though it compared the results of using different anesthetics in actual surgery.
B) When the study looked at other variables that are confounded with a doctor's choice of anesthetic, it found that Anesthetic C was not causing extra deaths. Suggest several variables that are mixed up with what anesthetic a patient receives.
Answers
Answer:
a) An experiment is conducted based on random observations not on certain selected observations.
b) age, blood type etc
Step-by-step explanation:
a) We call the National Halothane Study an observational study rather than an experiment, because the anesthetics were not randomly chosen. They were prescribed by the doctors.
An experiment is conducted based on random observations not on certain selected observations.
b) There are factors such as age, sex, intensity , limit, tolerance and reactivity of the patient with the particular anesthetics chosen. If these are not carefully studied the results may not be as rewarding as desired.
If an anesthetics is chosen wihtou knowing the age or blood type for tolerance it may result in dangerous situations.
Some patients are highly tolerant with certain medications but others may die.

Answer:
0.2762
Step-by-step explanation:
The point estimate is the best guess of the true parameter. It is an estimate of a population parameter and it is a single value of statistics.
The sample proportion [tex]\hat p[/tex] is the point estimate of the population proportion p
Given that
The sample mean = 274; &
The sample size = 992
Then,
The point estimate [tex]p = \dfrac{x}{n}[/tex]
[tex]p = \dfrac{274}{992}[/tex]
p = 0.2762

The cash cost is $4400.
She pays 10% down
The balance paid in 6
Monthly payment is $676
First , let's find the amount financed:
[tex]A=4400.\frac{90}{100} =3960[/tex]
The number of payments per year (n) are 6.
The time in years is half a year.(6 months)
The installment payment is $676.
The total amount paid is
[tex]676.6=4056[/tex]
Then, we subtract to obtain the finance charge
[tex]4056-3960=96[/tex]
Hence , the answer to (a) is $96, that's the finance charge
