For questions 7 and 8, state whether the investigation is an observational study or a designed experiment. Explain your answer.7. Researchers randomly assigned 39,876 initially healthy women 45 years of age or older to 100 mg of aspirin or placebo on alternative days and then monitored them for 10 years for a first major cardiovascular event (i.e. nonfatal myocardial infarction, non-fatal stroke, or death from cardiovascular causes).8. A study involving 3800 people over the age of 65 in East Boston. The study took place over a six year period and compared the age at which death occurred for right handed people vs. left handed people among the 3800 people who died during the six year period. The study concluded there was no difference.
Answer:
7. EXPERIMENTAL DESIGN
8. OBSERVATIONAL STUDY
Step-by-step explanation: Conducting researches may be structured as being observational or experimental. The difference between the two methods lies thus ;
Observational study requires that subjects or variables employed in the research study are data collected from a source or variables which aren't tampered with during the course of the research study. Here, variables or subjects are not subjected to any treatment before inference is made. Such is the case in scenario (8) whereby inference was made after observing variables involved in the research for 6 years without applying any treatment to either variable before inference was drawn or made.
Experimental design however, involves the actual application of treatment on the subjects involved in the study and their response being noted in other to make a conclusion. The groups may be divided into two ; the treatment group and the placebo group just like in the scenario above.

Enter a fraction or round your answer to 4 decimal places, if necessary.
Answer:
0.2390Step-by-step explanation:
Given
Total applicants = 431Applicants with graduate degree and over 5 years of experience = 103Probability = favorable outcomes/total outcomes

Given
Radius of a sphere = 3 cmRadius of a cylinder = 5 mm = 0.5 cmVolume of a sphere
V = 4/3πr³= 4/3*3³π = 36π cm³Volume of a cylinder
V = πr²h = π*0.5²h = 0.25πh cm³Comparing volumes to get the length of the wire

Which statements correctly describe the cosine and sine functions? Check all that apply.
The cosine function increases on (90°, 180°) and (270°, 360°).
The sine function increases on (0°, 90°) and (270°, 360°).
The cosine function decreases on (0°, 180°).
Both the cosine and sine functions have a minimum value of 0.
Both the cosine and sine functions have a maximum value of 1.
Both the cosine and sine functions are periodic.
Answers:
B: The sine function increases on (0°, 90°) and (270°, 360°).
C: The cosine function decreases on (0°, 180°).
E: Both the cosine and sine functions have a maximum value of 1.
F: Both the cosine and sine functions are periodic.
The only statements that correctly describe the cosine and sine functions are;
Option B: The sine function increases on (0°, 90°) and (270°, 360°).
Option C: The cosine function decreases on (0°, 180°).
Option E: Both the cosine and sine functions have a maximum value of 1.
Option F: Both the cosine and sine functions are periodic.
To answer this question, we need to first write the sine and cosine of angles 0°, 90°, 180°, 270° and 360°.
sin 0° = cos 90° = 0
cos 0° = sin 90° = 1
sin 180° = cos 270° = 0
cos 180° = sin 270° = -1
cos 360 = 1
sin 360 = 0
Let us look at the options;
Option A; Statement is not correct because cosine decreases from 90° to 180°.
Option B; This statement is correct because sine increases from 0 to 1 on (0°, 90°) and increases from -1 to 0 on (270°, 360°).
Option C; This statement is true because cosine decreases from 1 to -1 on (0°, 180°).
Option D; This statement is not true because they can also have negative values which are lesser than 0.
Option E; This statement is true because they both have a maximum value of 1.
Option F; This is true because since they repeat values they are said to be periodic.

0
5xy^3
9x^2 y
8y^4
4xy^3
The solution is, the last possibility is 9x^2 y – 5xy3 + 9x2y =18x^2 y – 5xy3, binomial degree 4.
What are Polynomials?Polynomials are sums of k-xⁿ terms, where k can be any number and n can be any positive integer.
here, we have,
First, if we have a polynomial that the form is as follow
P(x,y)=a1x^n-1y^p-1+ a2x^n-2y^p-2 + . . . . + a0xy+c,
the degree can be found with the sum of the highest value of power of each term.
If the number of term is 3, it is called trinomial, if it is 2, the polynomial is called binomial.
So in our case, 0– 5xy3 + 9x2y is a binomial with a degree of 4, because number of term 2, degree =1 + 2 =3, upper than 2+ 1(the second term) 4xy^3– 5xy3 + 9x2y = -xy3 +9x2y, binomial degree 4,
and the last possibility is 9x^2 y – 5xy3 + 9x2y =18x^2 y – 5xy3, binomial degree 4.
Hence, The solution is, the last possibility is 9x^2 y – 5xy3 + 9x2y =18x^2 y – 5xy3, binomial degree 4.

Answer:
Area = 90 units^2
Step-by-step explanation:
For the area of a triangle, we can simply use the following equation:
Area = ( 1 / 2 ) * Base * Height
We are given a base of 12 and a height of 15, so we can simply plug those values into the formula to find the area.
Area = ( 1 / 2 ) * Base * Height
Area = ( 1 / 2 ) * 12 * 15
Area = 6 * 15
Area = 90
Hence, the area of our triangle is 90 units^2.

Answer: The inverse of the linear function f(x)=2x+1 is f^(-1) (x) = (1/2)x-1/2
Solution
f(x)=2x+1
y=f(x)
y=2x+1
Isolating x: Subtracting 1 both sides of the equation:
y-1=2x+1-1
y-1=2x
Multiplying both sides of the equation by 1/2:
(1/2)(y-1)=(1/2)2x
(1/2)y-1/2=x
x=(1/2)y-1/2
Changing "x" by "f^(-1) (x)" and "y" by "x":
f^(-1) (x) = (1/2)x-1/2

What is square root?The square root of a number is that factor of a number which when multiplied by itself gives the original number. Squares and square roots are special exponents. Consider the number 9. When 3 is multiplied by itself, it gives 9 as the product.
This can be written as 3 × 3 or 3². Here, the exponent is 2, and we call it a square. Now when the exponent is 1/2, it refers to the square root of the number. For example, √n = n^(1/2), where n is a positive integer.

Interested in learning more about its fans, the marketing office of the Arena Football League (AFL) conducted a survey at one of its games. The survey has 937 respondents, 694 males and 243 females. Out of the 937 total respondent's, 194 stated that they had attended multiple AFL games. Of these 194 fans that had attended multiple games, 169 were male. Using this survey information, answer the following questions.
1- What is the probability that a randomly selected fan has attended multiple games?2- Given that a randomly selected fan has attended multiple games, what is the probability of this person being male?3- What is the probability of a randomly selected fan being male and having attended multiple games?4- Given that a randomly selected fan is male, what is the probability that this person has attended multiple games?5- What is the probability that a randomly selected fan is male or has attended multiple games?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
Total respondent : n(T) = 937
n(male) = 694
n(Female) = 243
n(multiple AFL) = 194
_______________AFL
Male ____694___169
Female __243___ 25
Total____ 937___194
1.) What is the probability that a randomly selected fan has attended multiple games?
n(Multiple AFL) / n(Total)
= 194 / 937
= 0.207
2.) Given that a randomly selected fan has attended multiple games, what is the probability of this person being male?
Male who attended multiple AFL / n(multiple AFL)
= 169 / 194
= 0.871
3- What is the probability of a randomly selected fan being male and having attended multiple games?
Number of males who have attended multiple games / n(Total)
= 169 / 937
= 0.180
4- Given that a randomly selected fan is male, what is the probability that this person has attended multiple games?
Number of males who have attended multiple AFL / n(male)
169 / 694
= 0.2435
5- What is the probability that a randomly selected fan is male or has attended multiple games?
[n(male) + n(multiple AFL)] / n(Total)
(694 + 194) / 937
= 888 / 937
= 0.9477
