Changing the compound inequality x > −3 and x < 3 from “and” to “or” will change the solution set

A sentence having two inequality statements connected by the words "or" or "and" is referred to as a compound inequality.

The conjunction "and" denotes the simultaneous truth of both statements in the compound sentence. It is when the solution sets for the various statements cross over or intersect.

The conjunction "or" means that the entire compound sentence is true as long as either statement is true. When "or" appears in a compound inequality, a disjunction is created.

Hence changing “and” to “or” changes the solution set

Answer: To calculate the percentage decrease in the number of available seats, we can use the following formula:

(original value - new value) / original value * 100

In this case, the original value is 125 (the number of available seats before the reduction) and the new value is 93 (the number of available seats after the reduction). Plugging these values into the formula:

(125 - 93) / 125 * 100 = 32 / 125 * 100 = 0.256 * 100 = 25.6

So, there is a 25.6% decrease in the number of available seats.

The given two lines are parallel to each other. The correct answer would be an option (A).

The slope of the line is defined as the gradient of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

The lines will be parallel if they have the same slope and they will be perpendicular if the product of the slopes of the two lines is -1.

The slope of the first line can be found using the formula:

m₁ = (-2 - (-5))/(5-9) = -3/4

The slope of the second line can be found using the formula:

m₂ = (1 - (-2))/ (-8 - (-4)) = -3/4

They have identical slope, so the lines will be parallel.

Hence, the given two lines are parallel to each other.

This system of equations has infinitely many solutions.

An equation is a mathematical statement that two expressions are equal. It can be written using numbers, symbols, and mathematical operations such as addition, subtraction, multiplication, and division. Equations can also be used to describe relationships between known values, like a line of best fit for data points. Equations are used in many areas of mathematics, such as geometry and calculus, to help solve problems or to describe physical phenomena.

This can be determined by looking at the coefficients of the variables. Since the coefficients of x in each equation are the same and the coefficients of y in each equation are different, this indicates that the equations are not equivalent and therefore, have infinitely many solutions.

The volume, V of box as a function of x that is V(x) = 4x³ - 64x² + 240x , where x is side of square cut out from each corner.

We have, a box open from top and constituted from rectugular pieces of dimensions 12 inches and 20 inches. As we know, The volume of a box is V

= width (w) × height(h) ×length (l).

Now, equal squares of side x are cut from each corner of box and folded. We draw our box it looks like as seen above figure. We will notice here that the height will be x and that the height and length depend on x. Length of box, l = 20 - 2x and

Width of box, w = 12 - 2x

So the volume is, V(x) = w×h×l

= (12 - 2x)(x)(20 - 2x)

Expand it for further calculation,

V(x) = ( 12 - 2x ) ( 20x - 2x²)

V(x) = 4x³ - 64x² + 240x

The volume, V, of a box is defined as V(x) = 4x3 - 64x2 + 240x.

We have a box that opens from the top and is made of rectangular components that are 12 inches and 20 inches in length. As is common knowledge, a box's volume is V.

V = height (h) + width (w) + length (l).

From each corner of the box, equal squares of side x are now cut and folded. We create a box that resembles the image above. Here, we'll see that the height is x and that the relationship between height and length is x-dependent.

Box length, l = 20 - 2x, and

Box width, w = 12 - 2x

Thus, V is the volume (x) = W * H * I

V(x) = (12 - 2x) (x) (20 - 2x)

V(x) = ( 12 - 2x ) ( 20x - 2x²)

V(x) = 240x - 24x² - 40x² -4x³

V(x) = 4x³ - 64x² + 240x

Hence, the required volume function is V(x) = 4x³ - 64x² + 240x.

The lower bound on the probability that the plant will fill between 9,000 and 11,000 cans on a particular day is at least 1 - 1/10 = 9/10.

What is probability ?

A probability is a number that reflects the chance or likelihood that a particular event will occur.

(a) P(X > 11,000) ≤ E[X] / 11,000

Where X is the random variable representing the number of cans filled in a day, and E[X] = 1,000 is the expected value.

So, P(X > 11,000) ≤ 1,000 / 11,000 = 1/11

(b) P(|X - E[X]| ≥ kσ) ≤ 1/k^2

Where X is the random variable representing the number of cans filled in a day, E[X] = 1,000 is the expected value, and σ is the standard

As we know that for any random variable X, E[X^2] >= (E[X])^2

therefore Var(X) = E[X^2] - (E[X])^2 >= 0.

so the standard deviation of X is

σ = √(Var(X)) = √(1000) = 31.62

We can choose k = (11000-9000)/(2*31.62) = 3.16

so P(|X - E[X]| ≥ 3.16σ) = P(|X - 1000| ≥ 10000) ≤ 1/3.16^2= 1/10

Therefore, the lower bound on the probability that the plant will fill between 9,000 and 11,000 cans on a particular day is at least 1 - 1/10 = 9/10.

[tex]y = \frac{1}{10}x - 1[/tex]

Step-by-step explanation:

We are given the equation x - 10y = 10.

We want to write it in slope-intercept form.

Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y intercept, hence the name.

Notice how in slope-intercept form, only y is on one side.

This is because the equation is basically solved for y in slope-intercept form.

So, we should solve the equation for y.

Start by subtracting x from both sides.

x - 10y = 10

-x           -x

_______________

-10y = -x + 10

Now, divide both sides by -10 to isolate y.

The curvature of r(t) at the point (3,1,1) is 2/3

The curvature of a space curve is given by the formula:

k(t) = |r'(t) x r''(t)| / |r'(t)|^3 where,

r(t) = (3t, t^2, t^3)

r'(t) = (3, 2t, 3t^2)

r''(t) = (0, 2, 6t)

So we can substitute these in the above formula:

k(t) = |(3, 2t, 3t^2) x (0, 2, 6t)| / |(3, 2t, 3t^2)|^3

By cross-product, we get

k(t) = |(6t, -6, -6t^2)| / |(3, 2t, 3t^2)|^3

Now substituting the point (3,1,1) we get

k(t) = |(6(1), -6, -6(1)^2)| / |(3, 2(1), 3(1)^2)|^3 = 6/9 = 2/3

Variance and standard deviation are two common measures of spread in statistics. The standard deviation is √30.25 = 5.5.

OB. s² = The sample variance is a measure of the spread of a set of data. To calculate the sample variance, the sum of the squares of the differences between each data point and the mean is divided by the number of data points minus one. In this case, the mean of the data set is (22+15+4+7+9)/5 = 11.

The differences between each data point and the mean are 11-22=-11, 11-15=-4, 11-4=7, 11-7=4, and 11-9=2. The sum of the squares of these differences is (-11)² + (-4)² + 7² + 4² + 2² = 121.

Dividing this by the number of data points minus one, which is 5-1=4, gives us a sample variance of 121/4 = 30.25.

The standard deviation is the square root of the sample variance, so in this case, the standard deviation is √30.25 = 5.5.
