Answer:

6 boxes of brownie mix

Step-by-step explanation:

48/8 is equal to 6

Part a: The proportion of scores are over 100 is 25.46%.

Part b: Best score below 57th percentile is 125.4.

For the given question;

Part a: For sample mean x = 100.

z = (x - μ)/σ

z = (100 - 120)/30

z = -0.66

Use negative z table

P(x = 100) = 0.2546

P(x = 100) = 25.46%

Thus, the proportion of scores are over 100 is 25.46%.

Part b: Best score below 57th percentile.

p = 0.57

Se z score from z score table for  p= 0.57

z = 0.18

0.18 = (x - 120)/30

x = 125.4

Thus, the best score below 57% is 125.4.

With the three matrices given which are 3x3 identity matrix, the value(s) of p for which the matrix C is invertible are p = 1/2, p = 4 + √6, and p = 4 - √6.

Computing the matrix product ATB

Thus,

ATB = \([(2 - 1/p), 1/2, 1, 0] [(1, -2), (2, -1)]\\= [(2 - 1/p)(1) + (1/2)(2), (2 - 1/p)(-2) + (1/2)(-1)]\\[(2 - 1/p)(2) + (1)(1), (2 - 1/p)(-1) + (1)(-2)]\\= [(4 - 1/p), (-4p + 1)/2]\\[(5 - 2/p), (-2 + 2/p)]\)

Then, add 2I3, we have;

C = \(ATB + 2I3 = [(4 - 1/p + 2), (-4p + 1)/2, 2]\\[(5 - 2/p), (-2 + 2/p + 2), 2]\\= [(6 - 1/p), (-4p + 5)/2, 2]\\[(5 - 2/p), (2/p), 2]\)

To determine the values of p for which C is invertible, use the determinant of C.

If det(C) is nonzero, then C is invertible.

det(C) = \([(6 - 1/p)(2/p) - (-4p + 5)/2(5 - 2/p)]\\[(5 - 2/p)(2) - (2/p)(-4p + 5)/2]\\= [(12 - 2/p^2 + 8p - 10)/2p] - [(10 - 4 + 4p - 5/p)/2]\\= [(2p^3 - 6p^2 + 5p + 5)/p] - [(5 - 4p + 5/p)/2]\\= [(4p^4 - 12p^3 + 10p^2 + 10p)/2p] - [(10p - 8p^2 + 10)/2p]\\= -(2p^3 - 9p^2 + 5p - 5)/2p\)

To find the values of p for which det(C) = 0, we need to solve the equation:

\(2p^3 - 9p^2 + 5p - 5 = 0\)

Use synthetic division  to factor this polynomial but notice that p = 1 is a root by inspection:

\(2(1)^3 - 9(1)^2 + 5(1) - 5 = 0\)

Therefore, we can factor the polynomial as:

\((2p - 1)(p^2 - 8p + 5) = 0\)

The roots of this equation are p = 1/2 and p = 4 ± √6.

Hence, matrix C is invertible for p = 1/2, p = 4 + √6, and p = 4 - √6.

The real-world problem involving a related set of two equations is given below:

Problem: Cost of attending a concert  is made up of base price and variable price per ticket. You are planning to attend a concert with your friends and want to know the number of tickets to purchase for lowest overall cost.

The related set of two equations are:

Equation 1: The total cost (C) of attending the concert is given by:

The equation C = B + P x N,

where:

B  = the base price

P  = the price per ticket,

N = the number of tickets purchased.

Equation 2: The maximum budget (M) a person have for attending the concert is:

The  equation M = B + P*X

where:

X = the maximum number of tickets a person can afford.

So by using the values of B, P, and M, you can be able to find the optimal value of N that minimizes the cost C while staying within your own budget M. so, you can now determine ticket amount to minimize costs and stay within budget.

Answer:

False roots are x = -1 or x = 5/2 or x = 3/2

Step-by-step explanation:

Solve for x:

4 x^3 - 12 x^2 - x + 15 = 0

The left hand side factors into a product with three terms:

(x + 1) (2 x - 5) (2 x - 3) = 0

Split into three equations:

x + 1 = 0 or 2 x - 5 = 0 or 2 x - 3 = 0

Subtract 1 from both sides:

x = -1 or 2 x - 5 = 0 or 2 x - 3 = 0

Add 5 to both sides:

x = -1 or 2 x = 5 or 2 x - 3 = 0

Divide both sides by 2:

x = -1 or x = 5/2 or 2 x - 3 = 0

Add 3 to both sides:

x = -1 or x = 5/2 or 2 x = 3

Answer:

Step-by-step explanation:

To show that the cylinder is a regular surface, and it's parametrization, we need to verify that it satisfies the two conditions of being a regular surface:

It must be a subset of R^3. This is true since the cylinder is defined in R^3.

For each point p on the cylinder, there exists a coordinate neighborhood (U, φ) such that φ(U ∩ S) is an open subset of R^2 and the coordinate map φ: U → φ(U) is a homeomorphism onto its image, and its differential is injective at every point q in U.

Let's consider the cylinder S = {(x, y, z) ∈ R^3 : x^2 + y^2 = 1}.

We can cover the cylinder with two coordinate neighborhoods: one using polar coordinates and the other using cylindrical coordinates.

Polar coordinates:

Consider the open set U = { (x, y, z) ∈ R^3 : 0 < y < π }.

Define φ : U → R^2 by

φ(x, y, z) = (x, z).

This is a homeomorphism onto its image, and the differential is injective at every point q in U. Therefore, φ is a local parametrization of the cylinder on U.

Cylindrical coordinates:

Consider the open set U = { (x, y, z) ∈ R^3 : 0 < x^2 + y^2 < 1 }.

Define φ : U → R^2 by

φ(x, y, z) = (θ, z),

where θ is the polar angle of the point (x, y) in the xy-plane.

This is a homeomorphism onto its image, and the differential is injective at every point q in U. Therefore, φ is a local parametrization of the cylinder on U.

Since the cylinder is covered by two local parametrizations, we can conclude that it is a regular surface.

Answer:

Step-by-step explanation:

300 times 5 equals 1500.

Answer: there are 118 dimes in the jar.

Step-by-step explanation: Let's use a system of equations to solve the problem:

Let d be the number of dimes and n be the number of nickels.

We know that:

d + n = 250 (Equation 1) (The total number of coins is 250)

0.1d + 0.05n = 18.4 (Equation 2) (The total value of all coins is $18.4)

To solve for d, we need to eliminate n from the equations above. We can do this by multiplying Equation 1 by -0.05 and adding it to Equation 2:

-0.05d - 0.05n = -12.5

0.1d + 0.05n = 18.4

0.05d = 5.9

Dividing both sides by 0.05, we get:

d = 118

Therefore, there are 118 dimes in the jar.

The correct option is A. The volume is 6.77 cubic units

The function and interval given are f(x) = (x - 1)^-1/4 and the x-axis on the interval (1, 6].

We want to find the volume of the solid of revolution when the region is rotated about the x-axis.

Let's consider the graph of the function: graph{(x-1)^(-1/4) [-10, 10, -5, 5]}

To set up the integral to find the volume of the solid of revolution, we can use the disk method.

We need to integrate the area of each disk perpendicular to the x-axis from x = 1 to x = 6.

The area of a disk is given by the formula: A = πr²

where r is the radius of the disk and is equal to f(x) in this case.

Therefore, the area of a disk is: A = πf(x)²

Let's substitute f(x) into this formula and integrate from x = 1 to x = 6 to get the volume of the solid.

We have The integral that should be used to find the volume of the solid is given as:

V = ∫₁⁶ πf(x)² dx

We substitute f(x) = (x - 1)^(-1/4) into this expression and integrate to get the volume.

We have: V = ∫₁⁶ π(x - 1)^(-1/2) dx

Let u = x - 1, so that du/dx = 1 and dx = du.

When x = 1, u = 0, and when x = 6, u = 5.

Therefore, we have: V = ∫₀⁵ πu^(-1/2) du= 2π[u^(1/2)]₀⁵= 2π(√5 - 1) ≈ 6.77 cubic units.

The volume of the solid of revolution when the region is rotated about the x-axis is approximately 6.77 cubic units.

Thus, the correct option is A. The volume is 6.77 cubic units.

On solving the provided question we can say that  the equation of the line will be  y+11 = 0.

The slope of a line is how steeply it slopes from left to right. The slope of a line is determined by dividing its rise (vertical change) by its slope, which is its horizontal change. Regardless of whatever two locations on the line you pick, the slope of the line is always constant (it never changes).

To find the coordinates of two points on the line, choose two. Find the difference between these two locations' y-coordinates (gradients). Find the difference between these two places' x coordinates (runs). Divide the change in the y coordinate by the difference in the x coordinate (slope/history or slope).

Here,

slope, m= 0 as these are parallel line.
