The Centers for disease Control and Prevention Office on Smoking and Health (OSH) is the lead federal agency responsible for comprehensive tobacco prevention and control. OSH was established in 1965 to reduce the death and disease caused by tobacco use and exposure to second-hand smoke. One of the many responsibilities of the OSH is to collect data on tobacco use. The following data show the percentage of adults in the United States who were users of tobacco from 2001 through 2011:
Year Percentage of Adults Who Smoke
1 22.9
2 21.7
3 21
4 20.3
5 20.3
6 19.9
7 19.4
8 20.7
9 20.7
10 19
11 18.8
What type of pattern exists in the data?
Use simple linear regression analysis to find the parameters for the line that minimizes MSE for this time series.
One of OSH’s goals is to cut the percentage of U.S. adults who were users of tobacco to 12% or less within nine years of the last year of these data. Does your regression model suggest that OSH is on target to meet this goal?
Use your model to estimate the number of years that must pass after these data have been collected before OSH will achieve this goal.

3x + 2(x + 2) + 4
In the first term, 3 is
In the second term, (x + 2) is
In the last term, 4 is
Answer:
[tex]3 \to[/tex] Coefficient of x
[tex](x+2)\to[/tex] Variable
[tex]4 \to[/tex] Constant
Step-by-step explanation:
Given
[tex]3x + 2(x +2) + 4[/tex]
Required
Complete the statements
In 3x, x is the variable; so:
[tex]3 \to[/tex] Coefficient of x
In 2(x + 2), 2 is the variable so:
[tex](x+2)\to[/tex] Variable
4 stands alone. So, it is a constant
[tex]4 \to[/tex] Constant
Answer: In the first term, 3 is a coefficient
In the second term, (x + 2) is a factor
In the last term, 4 is a constant
Step-by-step explanation:
The 3 in the first term is multiplied by a variable, x. So it is a coefficient.
The (x + 2) in the second term is multiplied by 2. So, it is a factor.
The 4 in the last term is not multiplied by anything. It is a fixed value, so it is a constant.

Answer:
x = 6.93
y = 13.86
Step-by-step explanation:
We can solve x by;
Tan(60) = 12/x
Tan(60) * x = 12
x = 12 / Tan(60)
x = 6.93
We can solve y by;
A² + B² = C²
12² + 6.93² = y²
144 + 48.02 = y²
192.02 = y²
[tex]\sqrt{192.02}[/tex] = y²
13.86 = y

Which is the graph of the linear equality 2x-3y<12
Answer:
The graph below shows the answer to
2x - 3y < 12
Also shown as
-3y < -2x + 12
Step-by-step explanation:
You can rearrange the inequality by subtracting 2x from both sides to isolate the y.
You now have -3y < 12 -2x
which can be put into the standard linear equation form of
-3y < -2x + 12
Then you divide both sides by -3 to get singular value of y, which is something like
-3/-3y < -2/-3x + 12/-3
which is
y > 2/3x -4
Note: I switched direction of the inequality because you are dividing both sides by a negative value.
Change fraction ( 11/4) from an improper fraction to a mixed number.
Answer:
Have a nice day :)
Step-by-step explanation:
To convert 11/4 into a mixed number, we need to divide 11 by 4 and get the values of quotient and remainder after performing division. When we divide 11/4, we get 2 as the quotient and 3 as the remainder. Now use the calculator to convert the following improper fractions to mixed fractions: 45/6
If the exercise ball has been filled with Nitrogen which has a density of 0.2 grams per cubic inches. Find the mass in grams.
Options
11,581.2 grams
12,370.6 grams
13,891.5 grams
15,156.3 grams
Answer:
m = 11581.2 grams
Step-by-step explanation:
Given that,
The density of the ball, d = 0.2 g/in³
The radius of the ball, r = 24 inches
We need to find the mass of the ball in grams.
The density of an object is hiven by :
[tex]d=\dfrac{m}{V}\\\\d=\dfrac{m}{\dfrac{4}{3}\pi r^3}\\\\m=\dfrac{4}{3}\pi r^3\times d[/tex]
Put all the values,
[tex]m=\dfrac{4}{3}\pi \times 24^3\times 0.2\\\\m=11581.16\ g[/tex]
or
m = 11581.2 grams
Hence, the mass of the ball is 11581.2 grams.

Answer:
A: Parameter
B: Population
C: Statistic
D: Variable
E: Sample
F: Data
Step-by-step explanation:
A- The average speed that all drivers go on Highway 50: This is the parameter because it is the mean of the population.
B- All people who drive on Highway 50: This is the Population because it is from here that the sample was taken.
C- The average speed that the 250 randomly selected drivers drove on Highway 50: This is the statistic because it represents the mean of the sample.
D- The speed that a driver drives on Highway 50: This is the Variable because it varies with each driver.
E- The 250 randomly selected drivers who were on Highway 50: This is the sample because it is taken from a part of the population.
F- The list of the 250 speeds that the drivers studied drove: This is the data because it gives us information on the different speeds for this specific research.

2.02b + 4.30 = 2.00b + 6.30
Answer: b = 100
Step-by-step explanation:
simplifying
2.02b + 4.30 = 2.00b + 6.30
reorder the terms:
4.30 + 2.02b = 2.00b + 6.30
reorder the terms:
4.30 + 2.02b = 6.30 + 2.00b
solving
4.30 + 2.02b = 6.30 + 2.00b
solving for variable 'b'.
move all terms containing b to the left, all other terms to the right.
add '-2.00b' to each side of the equation.
4.30 + 2.02b + -2.00b = 6.30 + 2.00b + -2.00b
combine like terms: 2.02b + -2.00b = 0.02b
4.30 + 0.02b = 6.30 + 2.00b + -2.00b
combine like terms: 2.00b + -2.00b = 0.00
4.30 + 0.02b = 6.30 + 0.00
4.30 + 0.02b = 6.30
add '-4.30' to each side of the equation.
4.30 + -4.30 + 0.02b = 6.30 + -4.30
combine like terms: 4.30 + -4.30 = 0.00
0.00 + 0.02b = 6.30 + -4.30
0.02b = 6.30 + -4.30
combine like terms: 6.30 + -4.30 = 2
0.02b = 2
divide each side by '0.02'.
getting: b = 100

Randy's gross salary is $760 per week. his salary is taxed at 16% what is his net salary
Answer:
$638.4
Step-by-step explanation:
Randy's gross salary (salary without any deduction) = $760
taxed rate =16%
Amount tax paid =tax% of gross income
=16/100 * $760
=$16*760/100
=$12160/100
=$121.6
net salary = gross salary - tax paid
=$760 - $ 121.6
=$638.4
Randy's net salary is $638.40
Randy's gross salary = $760 per week.
Tax paid on his salary = 16%
Net salary is the difference between the salary earned and the amount paid as tax. This will be:
= Salary - Tax
= $760 - (16% × $760)
= $760 - (0.16 × $760)
= $760 - $121.60
= $638.40

Liam bought pizza and wings for $27.58. How much change should Liam receive if he gave the clerk three $10 bills?
Use coins and bills to help solve.
A. $1.52
B. $2.42
C. $2.52
D. $12.42
Answer:
B. $2.42
Step-by-step explanation:
If Liam gave the clerk three $10 bills, that means he gave the clerk $30. This is because 3 times 10 equals 30.
Find how much change he will receive by subtracting $27.58 from the $30 that Liam gave to the clerk:
30 - 27.58
= 2.42
So, Liam will receive $2.42 in change.
The correct answer is B. $2.42
Answer:
2.42
Step-by-step explanation:
3 ten dollar bills = 3*10 = 30 dollars
Subtract the cost of pizza and wings
30 - 27.58
Line up the decimals
30.00
- 27.58
----------------
2.42
Out of 449 applicants for a job, 253 have over 5 years of experience and 62 have over 5 years of experience and have a graduate degree. Step 1 of 2 : What is the probability that a randomly chosen applicant has a graduate degree, given that they have over 5 years of experience
Answer:
The probability that a randomly chosen applicant has a graduate degree, given that they have over 5 years of experience, is 24.50%.
Step-by-step explanation:
Given that out of 449 applicants for a job, 253 have over 5 years of experience and 62 have over 5 years of experience and have a graduate degree, to determine what is the probability that a randomly chosen applicant has a graduate degree, given that they have over 5 years of experience, the following calculation must be performed:
253 = 100
62 = X
62 x 100/253 = X
6,200 / 253 = X
24.50 = X
Therefore, the probability that a randomly chosen applicant has a graduate degree, given that they have over 5 years of experience, is 24.50%.
NO LINKS NO FILES! Jill says that the rules for multiplying and dividing integers are alike. Do you agree? Explain.
Answer:
Multiplying and dividing fractions are essentially the same process which you multiply the numbers straight across and no need for common denominators. Except in division of fractions, the second fraction is flipped so that the denominator is on the top and the numerator is on the bottom (reciprocal).
Answer:
I do not agree
Step-by-step explanation:
because in multiply negatives, the 2 negatives turn into a positive or multiplying positive and negative (and vice versa) becomes a negative still so the rules of multiplying and dividing are not alike integers. (For dividing it is the same!)
