D is zero

Answer:12d-18

Step-by-step explanation:

Option A and C, To draw accurate conclusions about change in an experiment, both experimental control and causation are required.

Experimental control means that the experiment is designed and conducted in a way that allows for a clear determination of the effect of the independent variable on the dependent variable, by controlling for extraneous variables and minimizing the effects of confounding variables.

Causation means that a relationship exists between the independent variable and the dependent variable, such that a change in the independent variable directly and consistently results in a change in the dependent variable.

Correlation refers to the statistical relationship between two variables, but does not necessarily imply causation. A single case study provides information about a specific individual or situation, but may not be generalizable to a larger population.

From 2000 to 2015, total spending on personal consumption increased by 77.5%, while health care spending increased by 129.9%.

a. The approximate annual per capita spending on personal consumption in 2015 was $38,218. This figure was calculated by dividing the estimated total personal consumption expenditure of $12.3 trillion by the population of 321 million.

b. The approximate daily per capita spending on personal consumption in 2015 was $104.89. This figure was calculated by dividing the approximate annual per capita spending of $38,218 by 365 days.

c. Services accounted for approximately 67.2% of personal consumption spending in 2015. This figure was calculated by dividing the estimated total spending on services of $8.3 trillion by the total personal consumption expenditure of $12.3 trillion. This figure is consistent with my own spending, as the majority of my expenditure is devoted to services such as transportation, food delivery, and entertainment.

d. Health care accounted for approximately 17.1% of all personal consumption spending in 2015. This figure was calculated by dividing the estimated total spending on health care of $2.1 trillion by the total personal consumption expenditure of $12.3 trillion.

e. The percentage increase in total spending between 2000 and 2015 was 77.5%, while the percentage increase in health care spending between 2000 and 2015 was 129.9%. This was calculated by first subtracting the total spending on personal consumption in 2000 of $6.8 trillion from the total spending on personal consumption in 2015 of $12.3 trillion, and then dividing the result by the total spending in 2000. This was done for both total spending and health care spending, and the results were then multiplied by 100 to get the percentage increase.

From 2000 to 2015, total spending on personal consumption increased by 77.5%, while health care spending increased by 129.9%.

Question 2:

98 Gallons of paint

Step-by-step explanation:

Question 1:

Diameter: 10

radius: 5

circumference: 2π x 5

                        = 15.70796

Area: π x [tex]5^{2}[/tex]

       = 78.53981

Question 2:

To find the radius of the sphere: r=(3V4π)⅓

                                                         =(3·66844·π)⅓

                                                         ≈11.68555

To find the surface area of the sphere: A=4πr2

                                                                      =4·π·11.692

                                                                      ≈1715.96403                      

Since surface area is 1715.96403 and each gallon of paint can cover 350 square feet the number of gallons of paint needed to paint the water tower is:

The equation of the tangent at (2,7) is y = 4x - 1.y = x^2 + 3; t = 2

Given: y = x^2 + 3 and t = 2

We need to find the equation of the tangent at (2,7).

First, we find the slope of the tangent line by taking the derivative of the function:

y' = 2x

At x = 2, the slope is 2*2 = 4.

Now, we can use the point-slope form of the equation of a line to find the equation of the tangent line:

y - y1 = m(x - x1)

y - 7 = 4(x - 2)

Simplifying:

y = 4x - 1

Therefore, the equation of the tangent at (2,7) is y = 4x - 1.

we need to use the concept of the right triangle formed by the angle and the point in the coordinate plane.

Let's call the angle in standard position θ. The point (-1, 5) lies on the terminal side of θ. We can use the Pythagorean Theorem to find the length of the adjacent side (x) and the opposite side (y) of the right triangle formed by θ and the point.

x = √((-1)^2 + 5^2) = √(1 + 25) = √26

y = 5

The values of the six trigonometric functions of θ can then be found as follows:

sin(θ) = y/r = 5/√26

cos(θ) = x/r = -1/√26

tan(θ) = y/x = 5/(-1) = -5

csc(θ) = 1/sin(θ) = √26/5

sec(θ) = 1/cos(θ) = -√26

cot(θ) = 1/tan(θ) = -1/5

where r is the distance from the origin to the point, which can be found using the distance formula:

r = √((-1)^2 + 5^2) = √26

So the values of the six trigonometric functions of the angle in standard position with a point of (-1, 5) on its terminal side are: sin(θ) = 5/√26, cos(θ) = -1/√26, tan(θ) = -5, csc(θ) = √26/5, sec(θ) = -√26, and cot(θ) = -1/5.

Using compound interest, The future value of this investment at the end of year 1 is $16321.6.

Compound interest is the type of interest that is calculated using both the principal and the interest that has accumulated over the preceding period. In contrast to simple interest, compound interest does not factor in the principal when calculating the interest for a subsequent period.

Every six months, or every semi-annually, the compound interest is added up.

Thus,

Rate = 4% / 2 = 2% =0.02

P = $16,000

n = 2

The compound interest is given by:

[tex]A = P (1 + \frac{r}{n})^n[/tex]

[tex]A = 16000(1 + \frac{0.02}{2})^2[/tex]

B) About 90% of the confidence intervals will contain μ

The 90% confidence interval is a range of values that is constructed from a sample of data that has a 90% probability of containing the true population mean, μ. To calculate the 90% confidence interval from a sample, we use the formula:

[tex]CI = X ± z* (σ/√n)[/tex]

Where X is the sample mean, z is the z-score corresponding to a 90% confidence level, σ is the population standard deviation, and n is the sample size.

In this case, 110 students each selected a sample of 35 quiz scores from a population of 5000. So the sample size is n = 35. Assuming the population standard deviation is known, then we can use the formula to calculate the 90% confidence interval for each student.

The procedure used to show the converse of the Pythagorean Theorem is given as follows:

D. Knowing that 3² + 4² = 5², draw the 3-foot side and the 4-foot side with a right angle between them. The five foot side will fit to form a right triangle.

The Pythagorean Theorem states that for a right triangle, the length of the hypotenuse squared is equals to the sum of the squared lengths of the sides of the triangle.

Hence:

h² = 3² + 4²

h² = 25

h = 5.

The hypotenuse has the larger side length, hence the sides that are connected by the right triangle must be the two smaller sides, the three foot side and the four foot side, hence option D is correct.
