A function f is blank 1 of 1 linear on an interval ii if, for any choice of x1 and x2 in ii, with x1 < x2.

A function f is **question blank 1 of 1** linear on an interval **ii** if, for any choice of **x1** and **x2** in **ii**, with **x1** < **x2**, the function satisfies the properties of a linear function.t

In a linear function, the rate of change (slope) between any two points on the function is constant. This means that the function's value increases or decreases at a constant rate as we move along the interval.

The blank in the question refers to the specific term that should be filled. However, based on the given context, it seems that the most suitable term to fill the blank would be **"is"**. Therefore, the sentence would read as:

"A function f is linear on an interval ii if, for any choice of **x1** and **x2** in **ii**, with **x1** < **x2**, the function satisfies the properties of a linear function."

This statement highlights the key characteristic of a linear function, where the function's behavior between any two points on the interval is consistent and can be represented by a straight line.

The symbol 'n,' represents the total number of individuals or observations in the sample.

Answer:

The principal quantum number, n, describes the energy of an electron and the most probable distance of the electron from the nucleus. In other words, it refers to the size of the orbital and the energy level an electron is placed in. The number of subshells, or l, describes the shape of the orbital.

The average value of the function f(x) = 6x over the interval [0, 9] is 27.

To find the average value of a function over a given interval, you need to take the definite integral of the function over that interval, and divide by the length of the interval. In this case, the function is f(x) = 6x, and the interval is [0, 9].

So first, we need to find the definite integral of 6x over [0, 9]:

∫[0,9] 6x dx = 3x^2 |[0,9] = 243

Next, we need to find the length of the interval, which is simply 9 - 0 = 9.

Finally, we divide the definite integral by the length of the interval:

Average value of f(x) = (1/9) * 243 = 27

So the average value of the function f(x) = 6x over the interval [0, 9] is 27.

The length of a to the nearest 10th of an inch is 13.6 inches.

One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.

We have,

In ΔQRS q=9.6 inches r=9.9 inches and S=92.

So, s² = q² + r² - 2qr cos s

s² = 9.6² + 9.9² + 2(9.6)(9.9) cos 92.

s² = 190.71 + 190.08 x (-0.035)

Step-by-step explanation:

The response variable also known as the d pendent variable, is simply the variable we intend to measure based in a set of variables (independent variables or explanatory variables) which might cause it to change. For instance, the scenario above aims to look into how a certain relaxation method will affect the exam score, here, the variable we intend to measure is the response variable which is exam score. The exam score is affected by the impact the relaxation method has on the student, hence, the relaxation method is the independent or explanatory variable.

The power of the test is low and not sufficient to detect a significant difference between the two treatments with the given sample size of 35.

To calculate the expected power of the test, we need to consider the survival rates, the significance level, and the sample size. Let's follow these steps:

Determine the proportions
Old treatment survival rate (p1) = 0.75
New treatment survival rate (p2) = 0.85

Determine the significance level
Two-sided significant difference level (α) = 0.05

Calculate the pooled proportion
Pooled proportion (p) = (p1 + p2) / 2 = (0.75 + 0.85) / 2 = 0.80

Calculate the standard error
Standard error (SE) = √(p × (1 - p) × (1/n1 + 1/n2)) = √(0.80 × (1 - 0.80) × (1/35 + 1/35)) ≈ 0.065

Calculate the test statistic (z)
z = (p2 - p1) / SE = (0.85 - 0.75) / 0.065 ≈ 1.54

Find the critical value for the two-sided significant difference at the 5% level
z_critical = 1.96 (from a standard normal distribution table)

Calculate the power of the test
In this case, since the test statistic is smaller than the critical value (1.54 < 1.96), we cannot reject the null hypothesis at the 5% significance level.

Answer:

1 is the correct option

I think so

The equation describes the line in the slope-intercept form will be y = (1/3)x +(2/3). Option A is correct.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

\(\rm m =\dfrac{y_2-y_1}{x_2-x_1}\)

It is given that the slope of the line is −1/3 and passes through the points (−2,3)

A straight line is a combination of endless points joined on both sides of the point. It is shown by the slope-intercept form.

The standard form of the slope-intercept is,

y-y₁ = m(x-x₁)

y-3=−1/3(x-(-2)

y-3=-1/3(x+2)

y = -1/3 x - 2/3 +3

y= -1/3x -7/3.

Thus, the equation describes the line in the slope-intercept form will be y = (1/3)x +(2/3). Option A is correct.

The dimensions that minimize the cost are a square base with side length 4 meters and a height of 9 meters.

Let's assume the side length of the square base is x meters. The height of the container is h meters.

Volume = Length × Width × Height

144 = x² × h

144 = x²h

The cost of the base is given as $9 per square meter, and the area of the base is x² square meters. Therefore, the cost of the base is $9x².

The cost of the sides is given as $2 per square meter, and the area of each side is xh square meters. Since there are four sides, the total cost of the sides is 4 × $2 × xh = $8xh.

The total cost is the sum of the cost of the base and the cost of the sides:

Cost = $9x² + $8xh

Cost = $9x² + $8x(144 / x²)

Cost = $9x² + $1152/x

To find the dimensions that minimize the cost, we can take the derivative of the cost equation with respect to x, set it equal to zero, and solve for x.

d(Cost)/dx = 18x - 1152/x² = 0

18x³ - 1152 = 0

x³ = 1152 / 18

x³ = 64

x = 4

So, the side length of the square base is 4 meters. Substituting this value into the volume equation, we can find the height:

144 = 4² × h

144 = 16h

h = 9

Therefore, the dimensions that minimize the cost are: length = 4 meters and height = 9 meters.

To maximize the length of the third side, which I'll call x, it needs to be the longest side.

So by the triangle inequality theorem, 19+15>x, meaning the maximum whole number value of x is 33.

Answer: \(-\frac{31}{12}\)

Step-by-step explanation:

A. The minimum value is 18 (Round to the nearest tenth as needed.)

B. There is no minimum value.

A. To solve this problem, we can graph the feasible region formed by the intersection of the given constraints. The feasible region represents the set of points that satisfy all the constraints simultaneously.

Upon graphing the given constraints, we find that the feasible region is a triangle with vertices at (0, 3), (4, 1), and (5, 0).

Next, we evaluate the objective function z = 5x + 6y at each vertex of the feasible region.

z(0, 3) = 5(0) + 6(3) = 18
z(4, 1) = 5(4) + 6(1) = 26
z(5, 0) = 5(5) + 6(0) = 25

Thus, the minimum value of z is 18, which occurs at the vertex (0, 3) within the feasible region.

B. To solve this problem, we can graph the feasible region formed by the intersection of the given constraints. The feasible region represents the set of points that satisfy all the constraints simultaneously.

Upon graphing the given constraints, we find that the feasible region is unbounded and extends indefinitely in certain directions.

Since the feasible region is unbounded, there is no finite minimum value for the objective function z = 5x + 6y. The value of z can be arbitrarily large or small as we move towards the unbounded regions.

Therefore, in this case, there is no minimum value for z.

A writing system used to express numbers is known as a number system. It is the mathematical notation used to consistently express the numbers in a particular set using digits or other symbols. It represents the arithmetic and algebraic structure of the numbers and offers a distinctive representation for each number.

Now, For the 1000th term in Cai's list of positive integers excluding squares and cubes, we need to continue the sequence until we reach the 1000th term.

Starting with 2, we skip 1 and 4 (which is 2 squared),

so 3 is the third positive integer.

Next, we skip 8 (which is 2 cubed) and include 5, 6, and 7.

Skipping 9 (which is 3 squared), we add 10 and 11.

Skipping 16 (which is 2 to the fourth power), we include 12, 13, 14, and 15.

Skipping 25 (which is 5 squared), we add 17, 18, 19, 20, 21, 22, 23, and 24.

Skipping 27 (which is 3 cubed), we add 26 and 28.

Skipping 36 (which is 6 squared), we include 29, 30, 31, 32, 33, 34, 35, and 37.

Skipping 49 (which is 7 squared), we add 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, and 48.

Skipping 64 (which is 2 to the sixth power), we include 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, and 63.

Skipping 81 (which is 3 to the fourth power), we add 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 82, 83, 84, 85, 86, 87, 88, and 89.
