One or more of the mean differences are statistically significant, but not the precise location of the group differences.
In mathematical modeling, statistical modeling, and experimental sciences, there are dependent and independent variables. A variable that is independent is precisely what it sounds like. It is a stand-alone variable that is unaffected by the other variables you are attempting to assess. Age, for instance, might be an independent variable.
Dependent variables are so-called because, during an experiment, their values are examined on the assumption or presumption that they are governed by the values of other variables.

bag contains 9 real diamonds and 5 fake diamonds. if 9 diamonds are picked from the bag at random, what is the probability that all of them are real?
The probability that all of them are real is 0.01875 or 1.875%
If the diamonds are replaced after each draw:
The probability of drawing a real diamond is 9/14, found by making the numerator the number of real diamonds and adding the total number of diamonds to find the denominator. 5+9 = 14.
To find the probability of all 9 diamonds drawn being real, multiply 9/14 by itself 9 times. = 387420489/ 20661046784. This creates a probability of 387420489/ 20661046784. This cannot be reduced because there is no common factor. To express as a decimal, divide. 387420489/ 20661046784 = 0.01875. To turn this into a percent, multiply by 100. 0.01875*100 = 1.875
Hence, the probability that all of them are real is 0.01875 or 1.875%

Ben plays $119.00 to get his dog Sookie groomed if the sales taxes rate is 8.25% calculate the total cost Ben will pay
Total cost ben would pay for the dog will be $128.8175.
What is Percentage ?The proportion of value in relation to the original value is measured using the percentage concept. In business, percentages are frequently employed to calculate a company's profit or loss percentage. Additionally, it is used in schools and colleges to show the grades that pupils have earned. A percentage formula can be used to assess the pupils' grades. In general, the definition of a percentage is any ratio of a value to the total value multiplied by 100. The percentage is denoted by the sign %.
Ben paid for dog = $119.00
Grooming to be done = 8.25% of $119.00
Total cost of grooming = $9.8175
Total cost after grooming for dog = $119.00 + $9.8175
= 128.8175 is the actual cost of dog.

The effectiveness of a blood-pressure drug is being investigated.
An experimenter finds that, on average, the reduction in systolic blood pressure is 55.8 for a sample of size 29 and a standard deviation 7.9.
Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 90% confidence level).
Assume the data is from a normally distributed population.
Answer as a tri-linear inequality accurate to 3 decimal places.
A tri-linear inequality for the estimate of the drug that would lower a typical patient's systolic blood pressure (using a 90% confidence level) is; 53.3 ≤ x-bar ≤ 58.3.
Explain the term tri-linear inequality?Equal does not imply inequality. Tri signifies three. The range is defined in terms of inequalities by the tri-linear inequality.For the stated question-
Average of reduction in systolic blood pressure μ = 55.8.
Standard deviation s = 7.9.
Sample of size n = 29
The confidence interval is estimated as-
μ - t₀.₀₅(s/√n) ≤ x-bar ≤ μ + t₀.₀₅(s/√n)
Put the values-
55.8 - t₀.₀₅(7.9/√29) ≤ x-bar ≤ 55.8 + t₀.₀₅(7.9/√29)
On simplifying,
53.3 ≤ x-bar ≤ 58.3
Thus, a tri-linear inequality for the estimate of the drug that would lower a typical patient's systolic blood pressure (using a 90% confidence level) is; 53.3 ≤ x-bar ≤ 58.3.

Find the absolute extrema for the given function on the interval [15.6, 19.2). Write your answer in the form (x.f(x)). Round your answers to two decimal places. f(x) = In (12x^2 - 11x + 2)
Absolute Minimum: Absolute Maximum
the absolute extrema of the linear equation f(x) = 12x^2 -11x +2 are 27 (absolute maximum) for x = - 8 and - 9 (absolute minimum) for x = 4. (- 8, 27) and (4, - 9).
What are the absolute extrema of a linear equation within a closed interval?
According to the functions theory, linear equations have no absolute extrema for all real numbers, but things are different for any closed interval as absolute extrema are the ends of linear function. Now we proceed to evaluate the function at each point:
Absolute maximum
f(- 8) = 12x^2 -11x +2
f(- 8) = 27
Absolute minimum
f(4) = - 3 · 4 + 3
f(4) = - 9
By means of functions theory and the characteristics of linear equations, the absolute extrema of the linear equation f(x) = 12x^2 -11x+2 are 27 (absolute maximum) for x = - 8 and - 9 (absolute minimum) for x = 4. (- 8, 27) and (4, - 9).

The dimensions of the poster found having the smallest area is H = 35. 87 cm and W = 25.63 cm.
Explain the term rate change of area?We understand that we are attempting to find the minimum of both the area function because we are instructed to locate the smallest area.Let "W" represent the poster's overall width and "H" represent its overall height.Area A = H.W
Its printed material is either W - 4(2) or W - 8.
Its printed material is H - 6(2)
height = H - 12
The printed area is therefore (W - 8)(H - 12) = 380.
(W - 8)(H - 12) = 380
WH - 12W - 8H + 96 = 380
W(H - 12) - 8H = 284
W = (284 + 8H)/(H - 12)
Put the values in the area;
A(H) = H(284 + 8H)/(H - 12)
A(H) = (284H + 8H²)/(H - 12)
Differentiate with respect to H to find the rate change of area.
A'(H) = [(284 + 16H)(H - 12) - (284H + 8H²)(1)]/(H - 12)²
A'(H) = (284H - 3408 + 16H² - 192H - 284H - 8H²)/(H - 12)²
A'(H) = (8H² - 192H - 3408)/(H - 12)²
A'(H) = 8(H² - 24H - 426)/(H - 12)²
Put A'(H) = 0
8(H² - 24H - 426)/(H - 12)² = 0
Solving;
H = 35. 87 cm
Thus, W = 25.63 cm
Thus, the dimensions of the poster found having the smallest area is H = 35. 87 cm and W = 25.63 cm.

What is equation straight line?
Y = mx + c is the general equation for a straight line, where m denotes the line's slope and c the y-intercept. It is the version of the equation for a straight line that is used most frequently in geometry. There are numerous ways to express the equation of a straight line, including point-slope form, slope-intercept form, general form, standard form, etc. A straight line is a geometric object with two dimensions and infinite lengths at both ends. The formulas for the equation of a straight line that are most frequently employed are y = mx + c and axe + by = c. Other versions include point-slope, slope-intercept, standard, general, and others.
Given that a= -1.24 and b=33.966, the regression equation is y= axe + b y= -1.24x + 33.966.
Here, "y" stands for the maximum number of situps an individual may perform, and "x" stands for the daily television viewing hours.
The estimated number of situps for a person who watches x=2 hours of TV is y=-1.24*2 + 33.966 y= -2.48 + 33.966 y= 31.486

Every rational number can be expressed in decimal form. This argument cannot be used to demonstrate that rational numbers between 0 and 1 are countable. We frequently use this fact to demonstrate that rationals are countable since every rational number has a decimal representation that terminates on a non-teminating repeating sequence.
