Answer:
f(x) = [x – (4 + √20)][x – (4 – √20]
Step-by-step explanation:
In order to know the function that best describes the given f(x) that best reveals it's minimum or maximum, we need to know solve for x.
x² – 8x – 4 = 0
Using completing the square method
x² – 8x = 4
x² – 8x + 4² = 4 + 4²
(x – 4)² = 20
x = 4 ±√20
Therefore
f(x) = [x – (4 + √20)][x – (4 – √20]

The table shown below represents a function. Which of the following values cannot be used to complete the table?
X Y
-10 5
-25 10
-5 15
__ 20
1. -20
2. -15
3. -5
Answer:
3.-5 is correct
Step-by-step explanation:
We are given,
The table which represents a function.
Now, 'A function is a relation in which every element of the domain has a unique image'.
So, from the table, we see that,
-5 has the image 15.
So, it cannot have another image.
Thus, the number which cannot be used to complete the table is -5.
Hence, option C is correct.

Answer:
x = √3
Step-by-step explanation:
tan 30° = 1/x
x = 1.73
but to get it in radical form:
sin 30° = 1/hypotenuse
hypotenuse = 2
x² = 2²- 1² = 4 - 1 = 3
x = √3

A cohort study of smoking and lung cancer was conducted in a small island population. There were a total of 1,000 people in the study, and the study was conducted over a ten year period. Four hundred were smokers and 600 were not. Of the smokers, fifty developed lung cancer. Of the non-smokers, 10 developed lung cancer. In order to measure the strength of association between smoking and lung cancer in this population, which measure of exposure-disease association would you use
Answer:
A measure of exposure-disease association one could use is the odds ratio (OR)
Step-by-step explanation:
An Odds ratio (OR) is a statistical measure quantifying the level of association between two events such as an exposure and an outcome
The odds ratio gives the probability of outcome where there is a given amount of exposure
We have the table;
[tex]\begin{array}{ccc}&Developed \ lung \ cancer& Did \ not \ develop \ lung \ cancer\\Smokers&50&350\\Non-smokers&10&590\end{array}[/tex]
The odds ratio = (The number of smokers with the lung-cancer)/(The number of non-smokers with lung-cancer) ÷ (The number of smokers smokers without long cancer).(The number of non-smokers without long cancer)
∴ OR = (50/10) ÷ (350/590) = 59/7 = 8.[tex]\overline{428571}[/tex] ≈ 8.4
Therefore, a smoker is approximately 8.4 times more likely to develop lung cancer than a non-smoker.

What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
A 15% tip on a restaurant bill is $3.60.
Now,
Let the cost of bill is, $x
Hence, We can formulate;
⇒ 15% of x = 3.60
⇒ 15x/100 = 3.60
⇒ 15x = 360
⇒ x = 360 / 15
⇒ x = 24
Thus, The cost of bill is, $24
