The correct conclusion is A. Since the p-value is greater than the significance level, there is not sufficient sample evidence to conclude that the full-time placement rate is now less than 87% because the p-value is greater than 0.05.

For the null hypothesis, 87% of the graduates find full-time employment in their field within the first year of graduation. It is tested if the proportion is still of 0.87, so:

H₀: p = 0.87

For the alternative hypothesis, less than 87% of the graduates find full-time employment in their field within the first year of graduation. It is tested if it has decreased, so:

H₁: p < 0.87

Since the p-value is greater than the significance level (p-value is greater than 0.0), we do not reject the null hypothesis, and thus, the correct conclusion is A.

Answer:

Step-by-step explanation:

When two system of linear equations solved by Sara represents the lines parallel to each other then the equations have no solution.

Step by Step explanation:

Given system of two linear equations :

Let us consider system of two linear equation with Sara has :

y =  3x + 7

y = 3x + 9

Here both the lines have same slope = 3

Lines are parallel to each other.

Solve the equation by elimination method :

y =  3x + 7

y = 3x + 9

0 = 0x - 2

⇒ -2 = 0 which is not possible and has no solution.

Therefore, when the system of linear equations with Sara has no solution it represents lines are parallel to each other.

Answer:

The square's area will be larger

Step-by-step explanation:

Let's say that a square's side length is 10.

To find the perimeter of a square, we add up all of the sides.

10 + 10 + 10 + 10 = 40

The perimeter of the square would be 40.

Now let's figure out the area of this square.

To find the area, we multiply the length by the width.

10 × 10 = 100

The area of the square is 100.

Now let's move on to the rectangle.

The rectangle has a side length of 12, and 8.

Let's figure out the perimeter of this rectangle.

12 + 12 + 8 + 8 = 40

The perimeter of the rectangle is 40, which means that the perimeters are the same.

Now let's figure out the area.

If you remember, to find the area we multiply the side length by the width.

12 × 8 = 96

The area of the rectangle is 96.

If the area of the square is 100, and the area of the rectangle is 96, then we can conclude that the area of a square is larger.

If a rectangle and a square have the same perimeter then Square will have a larger area.

Suppose length of rectangle is 6 cm and breadth is 2 cm.

So, Area of a rectangle = length ×  breadth

                                  =(6×2) cm²

                                  = 12 cm²

Given that,

Perimeter of rectangle = Perimeter of square

2× (length + breadth)   =  4×side

Side = [tex]\frac{2 ( length + breadth)}{4}[/tex]

Side =  [tex]\frac{2 (6+2)}{4}[/tex]

Therefore, side = 4 unit.

Now,  Area of Square = (side)²

                                    = ( 4 )²

                                      16 unit²

Hence, Area of square (16) is more than area of rectangle (12).

An explicit description of Nul A is given by the set of vectors {[0, 0, 1, 0], [0, 0, 0, 1]}.

What is the explicit description of a null space matrix?

To find an explicit description of the null space of matrix A, we can find a spanning set of vectors that span the null space.

The null space of matrix A, denoted Nul A, is the set of all vectors x that satisfy the equation Ax = 0. In other words, the null space consists of all vectors that are mapped to the zero vector by the matrix A.

To find a spanning set for Nul A, we can use the following steps:

Row reduces the matrix A to a reduced row-echelon form using elementary row operations.

Identify the free variables in the row-reduced matrix.

For each free variable, create a vector with a 1 in the position corresponding to the free variable and 0's in all other positions.

The set of vectors created in step 3 form a spanning set for Nul A.

For example, consider the matrix A = [1, 2, 3, 0; 0, 0, 1, 0]. To find a spanning set for Nul A, we can row reduce the matrix to reduced row-echelon form:

[1, 2, 3, 0] -> [1, 2, 3, 0]

[0, 0, 1, 0] -> [0, 0, 1, 0]

The matrix is already in reduced row-echelon form, so there are no more elementary row operations to perform. The free variables in this matrix are the third and fourth columns, which correspond to the variables x3 and x4, respectively. Therefore, we can create the following vectors:

x3 = [0, 0, 1, 0]

x4 = [0, 0, 0, 1]

These vectors form a spanning set for Nul A, as they are linearly independent and span the null space.

Hence, an explicit description of Nul A is given by the set of vectors {[0, 0, 1, 0], [0, 0, 0, 1]}.

The length, width and area of the smaller rectangle are 18 cm, 14 cm and 252 cm² respectively.

A rectangle is a polygon in two dimension with four sides with opposide sides are equal and all the angles are right angles.

Given smaller rectangle is 1/2 scale drawing of the original figure. So the dimensions of the smaller rectangle will be half of the dimensions of the bigger rectangle.

For bigger rectangle,

Length = 36 cm

Width = 28 cm

Area = 1,008 cm²

So for smaller rectangle,

Length = 36/2 = 18 cm

Width = 28/2 = 14 cm

Area = 18 × 14 = 252 cm²
