Use the formula V=s^3 to find the volume of a cube with the sides of length s= 2 1/4 inches

Answers

Answer:

6.375 cubic inches

Step-by-step explanation:

To find the volume of a cube using the formula V = s^3, where s represents the length of one side, we simply need to raise s to the power of 3.

Given that the length of one side, s, is 2 1/4 inches, we need to first convert the fractional part to decimal form:

[tex]\sf:\implies{2 1/4 inches = 2 + 1/4 inches}[/tex]

[tex]\sf:\implies{= 2.25 inches}[/tex]

Now, we can use this value in the formula:

[tex]\sf:\implies{V = s^3 = 2.25^3}[/tex]

To raise a number to the power of 3, we simply multiply the number by itself three times:

V = 2.25 × 2.25 × 2.25 = 6.375 cubic inches

Therefore, the volume of the cube with sides of length 2 1/4 inches is 6.375 cubic inches.

suppose you have a biased coin with probability p of heads. flip the coin until two tails appears. find probabiility

Answers

Let's call the event of flipping two tails in a row "success." The probability of success on any given flip is (1-p) ^2.

The number of flips required to get two tails in a row is a random variable, which we can calculate the expected value of. This expected value can be calculated as an infinite sum:

E = 1 * (1 - (1-p) ^2) + 2 * (1-p) ^2 * p + 3 * (1-p) ^2 * (p^2) + ...

This sum can be simplified using geometric series formula:

E = 1 / (1 - (1-p) ^2 * p)

So, the expected number of flips required to get two tails in a row with a biased coin with probability p of heads is given by the above formula.

Answers

The square of a binomial, when the binomials are subtracted, is defined as follows:

(a - b)² = a² - 2ab + b².

How to obtain the square of a binomial?

When the two binomials are added, the square is given as follows:

(a + b)².

Expanding the square, we have that:

(a + b)² = (a + b) x (a + b).

(a + b)² = a² + ab + ab + b².

(a + b)² = a² + 2ab + b².

Which is the result presented in this problem.

Now, when the binomial has a minus sign, involving a subtraction, the pattern is obtained as follows:

(a - b)² = (a - b) x (a - b).

(a - b)² = a² - ab - ab + b².

(a - b)² = a² - 2ab + b².

The midpoint of AB is at (-5,0). If A=(-7,-2), find B

Answers

Point B of line segment AB = (-3 , 2)

What is mid-point?

The midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.

Given,

Midpoint of AB = (x , y) = (-5, 0)

A = (x₁ , x₂) = (-7, -2)

Let B = (x₂ , y₂)

Midpoint (x , y) = [(x₁ + x₂)/2 , (y₁ + y₂)/2]

(-5, 0) = [(-7 + x₂)/2 , (-2 + y₂)/2]

Comparing horizontal coordinates,

(-7 + x₂)/2 = -5

(-7 + x₂) = -10

x₂ = -10 + 7

x₂ = -3

Comparing vertical coordinates

(-2 + y₂)/2 = 0

(-2 + y₂) = 0

y₂ = 2

B = (x₂ , y₂) = (-3 , 2)

Hence, (-3 , 2) is point B of line segment AB.

Answers

The length of segment BC is 27.4.

How to calculate segments?

To find the length of segment BC, we need to use the Pythagorean theorem on triangle BCD. The theorem states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the longest side (the hypotenuse). We know that BD = 12 and CD = 30, the equation is:

BC² = CD² - BD²

Substituting the values:

BC² = 30² - 12²

BC² = 900 - 144

BC² = 756

Finally, taking the square root of both sides:

BC = √(756) = 27.4

So the length of segment BC is approximately equal to 27.4.

Tutorial Exercise Find the length and width of a rectangle with maximum area that has a perimeter of (8P) units. Step 1 Recall that the perimeter of a rectangle is given by the following equation where sp is the perimeter, L is the length, and w is the width. 2L + 2w =P We are given that the rectangle has a perimeter of sp units. Further, let x represent the length of the rectangle and let y represent the width. Therefore, the equation for the perimeter of the rectangle in terms of x and y is as follows. 2x + 2y = BP Solve this equation for y. 2x + 2y - BP 2yBP - 2x BP - 2x Y

Answers

The width of the rectangle is y = (8P - 2x) ÷ 2 and the maximum area of the rectangle is A = x x y.

The perimeter of a rectangle is given by the following equation: 2L + 2w = P, where P is the perimeter, L is the length, and w is the width. We are given that the rectangle has a perimeter of 8P units. Let x represent the length of the rectangle and let y represent the width. Then, the equation for the perimeter of the rectangle in terms of x and y is: 2x + 2y = 8P.

To solve for y, we can subtract 2x from both sides of the equation to get: 2y = 8P - 2x. Then, we divide both sides of the equation by 2 to get: y = (8P - 2x) ÷ 2.

Now, we can use the area formula for rectangles, A = L x w, to determine the maximum area of a rectangle with a perimeter of 8P units. Substituting the values for length and width, we get: A = x x (8P - 2x) ÷ 2. We can rearrange this equation to make x the subject: A = x x (8P - 2x) ÷ 2 → x2 - (8P/2)x + A = 0.

Now, we can use the quadratic equation to solve for the length of the rectangle, x. We get: x = (8P ± √(64P2 - 16A)) ÷ 4. Therefore, the width of the rectangle is y = (8P - 2x) ÷ 2 and the maximum area of the rectangle is A = x x y.

Write the dividend and the divisor in their respective positions.
Take the first digit of the dividend from the left.
If this digit is greater than or equal to the divisor, then divide it by the divisor and write the answer on top as the quotient.
Write the product below the dividend and subtract the result from the dividend to get the difference. If this difference is less than the divisor, and there are no numbers left in the dividend, then this is considered to be the remainder and the division is done.

A discrete uniform distribution is a type of probability distribution where all outcomes are equally likely. This means that the probability of each outcome is the same. For example, if you were to roll a die, each number from 1 to 6 would have the same probability of being rolled. This type of distribution is commonly used when there are a finite number of outcomes, such as rolling a die or flipping a coin. In this case, the probability of each outcome is the same, resulting in a uniform distribution. This type of distribution is useful when all outcomes are equally likely, such as when a fair die is rolled. In such a situation, a discrete uniform distribution is the most appropriate model for the probability of each outcome.

The general antiderivative of a rate of change function is calculated by integrating the rate of change expression over the given interval. In this case, the rate of change of DVD orders is given by s(m) = 500m + 8 DVDs per month. We can calculate the general antiderivative of this expression by integrating it over the given interval from m = 0 (the beginning of the year) to some arbitrary value m.

To calculate the value of S(m) for any given value of m, we simply plug the value of m into the expression above and solve for S(m).

What is Relative frequency?

The ratio (fraction or proportion) of the number of times a data value appears in the set of all outcomes to the total number of outcomes is known as the relative frequency.

Divide each frequency by the overall sample size, in this example 20 students, to determine the relative frequencies.

Example: Out of a total of 12 games played, your team has won 9 of them, making its winning percentage 9 percent. 9/12, or 75%, is the relative frequency of winning.

So, we have:

RF(A) = f(A) / ∑f

Where f(A) is the frequency of event A and ∑f is the total frequency.

(Refer to the table attached below)

Total car = 251 + 198 + 195 + 293 = 937

The relative frequency of blue cars is as follows:

The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur.

Probability and odds are two distinct ideas.

Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

Mathematics' study of random events is known as probability, and there are four primary types of probability: axiomatic, classical, empirical, and subjective.

So, employees who know C/C++ are 60%.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

The equation y=ax+4 is in the slope-intercept form.

Therefore, the slope m=a and the y−intercept b=4

The equation y=bx−2 is in the slope-intercept form.

Therefore, the slope m=b and the y−intercept b=−2

Since the two lines have different y−intercept, they can never be the same for any values of a and b.

Therefore, the system can never have infinitely many solutions.

a square is plotted on a coordinate plane. henry claims that any transformation on the square will preserve the length of its sides.which of the following transformations could be used to show that henry's claim is incorrect? select all that apply.

Answers

The transformations that could be used to show that Henry's claim is incorrect are:

Horizontal stretch by a factor of 1/3.

Dilation by a factor of 2 units through origin.

Given that a a square is plotted on a coordinate plane.

Henry claims that any transformation on the square will preserve the length of its sides.

We need to check which claims is incorrect.

We must find transformations that do not maintain the length of the square's sides in order to refute Henry's assertion.

Analyzing each transformation now:

a) A translation of 5 units to the right:

The square's shape is unaltered by this transformation. The length of the sides does not change, but the square is merely moved 5 units to the right. The sides' length is preserved by this modification.

b) A horizontal stretch of the square by a factor of 1/3:

This change enlarges the square horizontally. The lengths of the original square's sides will not be kept because they will be multiplied by a factor of three-quarters. The sides' length is not preserved in this change.

c) Two-unit dilation through the origin:

This transformation uniformly scales the square by a factor of two. The lengths of the sides will alter as a result of multiplying all of them by 2. The sides' length is not preserved in this change.

d) Rotation of the square 45 degrees clockwise about its center:

This transformation spins the square, but the side lengths stay the same. The length of the sides are preserved by this translation because the rotation does not change the square's dimensions.

Therefore, the following transformations could be used to refute Henry's assertion:

b) Horizontal stretch by a factor of 1/3.

c) Dilation by a factor of 2 units through the origin.
