In the article "Foods, Fortificants, and Supplements: Where Do Americans Get Their Nutrients?" researchers analyze the nutrient and vitamin intake from a random sample of 16,110 U.S. residents. Researchers compare the level of daily vitamin intake for vitamin A, vitamin B-6, vitamin B-12, vitamin C, vitamin D, vitamin E and calcium. Unless otherwise stated, all hypothesis tests in the study are conducted at the 5% significance level.
Researchers conduct a hypothesis test to determine if the proportion of U.S. residents consuming recommended levels of calcium is different among women and men. The p-value is 0.035, and researchers conduct this test at a 5% level of significance. What does a p-value of 0.035 mean?
There is a 3.5% chance that there is no difference in calcium consumption for women and men.
If the calcium consumption rates are different for the women and men, there is a 3.5% chance that future experiments will show the same difference in calcium consumption as observed in this experiment.
If calcium consumption is the same for women and men, there is a 3.5% chance that future studies will show differences in calcium consumption greater than observed in this study.
If calcium consumption is the same for women and men, there is a 3.5% chance that calcium consumption will be different in future experiments.

The equation of line in slope in intercept form will be equal to y = 4x - 4.

It is possible to determine a line's direction and steepness by looking at its slope. Finding the slope between lines inside a coordinate plane can aid in anticipating if the lines are perpendicular, parallel, or none at all without physically using a compass.

As per the data provided in the question,

The formula for a line is y = mx + b, where m denotes the slope and b the y intercept.

So,

The equation can be written as,

y = 4x + b

As per the given point (2, 4),

4 = 4(2) + b

b = 4 - 8

b = -4

So, the final equation will be,

Step-by-step explanation: bc ? you just divid 54 by 3 and 6 then you divid 77 by 4 and 9 then divide them both tada

Answer:

sodas cost $5 and a large popcorn costs $8

create formulas out of the situations making the variable p=popcorn and s=soda

so,

3p + 6s = 54

and

4p + 9s = 77

then choose one variable to solve for

3p = 54 - 6s

divide both sides by 3

p = 18 - 2s

then plug your answer for p into the other equation:

4(18 - 2s) + 9s = 77

finally, solve for s

72 - 8s + 9s = 77

s = 5

if s=5 then

3p + 6(5) = 54

p = 8

Given the set of data, we can calculate that the mean is 9.5, the variance is 17.58 and the standard deviation is 4.19

Mean, variance, and standard deviation

The concepts of mean, variance and standard deviation are very basic but very important in statistics.

Mean is the average of all data in a sample group, which is obtained by adding up all the data values, then dividing by the number of samples.

[tex]mean = \frac{sum all of the data}{size of data}[/tex]

Variance is a value that describes the variation of data, by measuring how far each piece of data is spread from the average of a data set.

[tex]variance = \frac{sum (x_{i} - mean)^{2} }{n}[/tex]

Standard Deviation is a measure of the spread of observations in a data set relative to their mean. it measures how many observations in a data set differ from the mean and is the square root of the variance.

σ = [tex]\sqrt{variance}[/tex]

Now we can calculate the mean of the given data as follows:

[tex]mean = \frac{sum all of the data}{size of data}[/tex]

         = (3 + 6 + 8 + 12 + 13 + 15) / 6

         = 57 / 6

         = 9.5

Then we can calculate the variance as follows:

[tex]variance = \frac{sum (x_{i} - mean)^{2} }{n}[/tex]

              = [tex]\frac{((3-9,5)^{2} + (6-9,5)^{2} + (8-9,5)^{2} + (12-9,5)^{2} + (13-9,5)^{2} + (15-9,5)^{2} )}{6}[/tex]

              = (42,25 + 12,25 + 2,25 + 6,25 + 12,25 + 30,25) / 6

              = 105.5 / 6

              = 17.58

Standard deviation can be calculated from the variance:

σ = [tex]\sqrt{variance}[/tex]

  = [tex]\sqrt{17.58}[/tex]

  = 4.19

Volume of solid generated by revolving the region bounded by the graph is 3817.53 unit

A volume is created while a plane figure rotating about an axis or around any straight line situated on the same plane.

We apply definite integration to calculate the required volume.

we are given the equation y = 5x² and y =0, x= 3

volume is calculated by using the formula, V = ∫π y² dx

                                                                      V = ∫₀³π (5x²) ² dx

On the y-axis x = 0 so upper limit x = 3 and lower limit x= 0

                                                          V= π × 25/5 [x⁵] ³₀

                                                        V = 15.71 [3⁵- 0]

The linear equation that represent the total cost after x month is y = 35 + 29.95x.

What is linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

Given that, a cable operator offer at $29.95 per month plus a one-time installation fee.

Assume that, a be one time installation fee.

After x month, they need to pay without one-time installation fee is 29.95x.

The total amount that need to pay after x month is a + 29.95x

The linear equation that represents total cost after x month is

y = a +  29.95x

Putting y = 214.70 and x = 6

214.70 = a +  29.95 × 6

214.70 = a +  179.70

a = 35.

Therefore:

The percentage of higher risk is unaffected by exposure as relative risk in unity.

In order to determine the strength of the relationship between exposures (treatments or risk factors) and outcomes, relative risk is employed in the statistical analysis of data from ecological, cohort, medical, and intervention studies. For instance, in a study looking at how the drug apixaban affected the occurrence of thromboembolism, 8.8% of patients receiving a placebo developed the condition, whereas only 1.7% of patients receiving the medication did. This means that the relative risk is.19 (1.7/8.8), meaning that patients receiving apixaban had 19% the disease risk of patients receiving a placebo. [4] In this instance, apixaban lowers the probability of disease, making it a protective rather than a risk factor.

Values of relative risk can be understood as long as the relationship between the exposure and the result is assumed to be causal.

RR = 1 denotes that the outcome is unaffected by exposure.

When the risk of the outcome is less than 1, this is referred to as a "protective factor."

RR > 1 indicates that the exposure, a "risk factor," has an effect on the outcome's risk.

Therefore, the percentage of higher risk is unaffected by exposure as relative risk in unity.

1. The solution to the quadratic equation, x² - 14x + 49 = 40, is x = 13.32 and x = 0.68

2. The solution to the quadratic equation, x² - x = 12, is x = -3 and x = 4

3. i. The factors of 2x² - 15x - 8 = 0 are (2x +1) and (x - 8)

ii. The x-intercepts of 2x² - 15x - 8 = 0 are x = -1/2 and x = 8

From the question, we are to solve the given quadratic equation by completing the square.

The given equation is

x² - 14x + 49 = 40

Solving the equation

x² - 14x + 49 = 40

x² - 14x = 40 - 49

x² - 14x = -9

Multiply the coefficient of x by 1/2 square and add to both sides

x² - 14x + (-7)² = -9 + (-7)²

(x - 7)² = -9 + 49

(x - 7)² = 40

x - 7 = ±√40

x = 7 ± √40

x = 7 ± 6.32

x = 7 + 6.32 OR 7 - 6.32

x = 13.32 OR 0.68

Solving x² - x = 12 by factoring

x² - x = 12

x² - x - 12 = 0

x² -4x + 3x - 12 = 0

x(x - 4) + 3(x - 4) = 0

(x + 3)(x - 4) = 0

x + 3 = 0 OR x - 4 = 0

x = -3 OR x = 4

Determining the factors of 2x² - 15x - 8 = 0

2x² - 15x - 8 = 0

2x² - 16x + x - 8 = 0

2x(x - 8) + 1(x - 8) = 0

(2x + 1)(x - 8) = 0

The factors are (2x +1) and (x - 8)

Determining the x-intercepts

(2x + 1)(x - 8) = 0

2x + 1 = 0 and x - 8 = 0

2x = -1 and x = 8

x = -1/2 and x = 8
