Using the z-distribution, as we have the standard deviation for the population, it is found that the 99% confidence interval for the population mean is given by:

[tex]\overline{x} \pm 2.58\frac{s}{\sqrt{n}}[/tex]

The confidence interval is:

[tex]\overline{x} \pm z\frac{s}{\sqrt{n}}[/tex]

In which:

99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so [tex]z = 2.58[/tex].

The other parameters are symbolic, hence the interval is given by:

[tex]\overline{x} \pm 2.58\frac{s}{\sqrt{n}}[/tex]

Angle is formed by the two rays. The angle with measurement –102° will lie in the third quadrant.

An angle is formed by the two rays, the two rays are known as the two sides of the angle.

As it is given that the measure of the angle is –102°, therefore, the angle will be measured from the positive x-axis in the clockwise direction, therefore, the angle will lie in the third quadrant as shown in the image below.

Answer:

x = 6

The measure of one part of a rectangle divided into 4 parts is 1/4

If 1 whole is divided into 4 equal parts

= 1/4

So, if the perimeter of the rectangle is 60cm

1 part of 4 = 1/4 × 60cm

= 60/4

= 15 cm

Therefore, the measure of one part of a rectangle divided into 4 parts is 1/4

Answer: 1/2 and 2

Step-by-step explanation:

The slope of a line, where the equation is in y=mx+b form, is m.

There are 4 positions in the string that each have 25 choices (any letter in the English alphabet except A) and the other positions are filled with A, so there are 25⁴ possible strings containing exactly 7 A's.

Overall, there are 26¹¹ possible strings of length 11.

Then the probability of randomly generating a string containing exactly 7 A's is

25⁴ / 26¹¹ ≈ 0.000000000106427

By finding the linear equation that relates distance and time, we can see that the complete table is:

time (hours)   distance (miles)

2                              100

1.5                             75

t                              (50)*t

1                                50

6                               300

d/(50)                          d

After a small online search, I've found that the table is:

time (hours)   distance (miles)

2

1.5

t  

                                50

                               300

                                  d

Now, remember the relation:

distance = speed*time.

In this case, we know that the speed is 50 mi/h, so if we define d as the distance and t as the time, we can write:

d = (50mi/h)*t

To complete the table, we just replace the value that appears in the table, and then we solve the equation for the other variable.

First we have t = 2 hours:

d = (50 mi/h)*2h = 100 mi

Then we have t = 1.5 hours

d = (50 mi/h)*1.5 h = 75 mi

Then we assume that we evaluate in t, so there we just write the equation:

d = (50 mi/h)*t

Now we go to the other side of the table, now we evaluate d, so we can write:

t = d/(50 mi/h)

(that is what goes in the table when we need to evaluate in d).

Then the fourth place in the table has d = 50 mi, replacing that:

t = (50mi)/(50 mi/h) = 1h

And finally, we evaluate in d = 300mi

t = (300 mi)/(50 mi/h) = 6h

Then the complete table is just:

time (hours)   distance (miles)

2                              100

1.5                             75

t                              (50)*t

1                                50

Answer:

L= P/2 - 6

Step-by-step explanation:

As you know that the Perimeter of a Rectangle = 2(L+W)

since Perimeter = P  and Width = 6

Then P = 2(L+6)

Expanding

P=2L+12  -->  2L=P-12

Then L=(P-12)/2=P/2-6

The perimeter is twice the sum of width and length. Then the length of the rectangle is P/2 – 6 units.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

If the width of a rectangle with perimeter P is 6 units.

Perimeter = P

Width = 6 units

Then the length of the rectangle will be

Perimeter = 2 (Width + Length)

             P = 2 (6 + L)

             L = P/2 – 6

The length of the rectangle is P/2 – 6 units.

Answer:

D. 60cm²

Step-by-step explanation:

First, notice how the partially shaded squares fit perfectly into one another (the squares are perfectly cut from corner to corner). Once you match these squares to one another, you can then figure out that they add up to three full squares.

Secondly, measure how many squares there will be in the diagram after adding up the partial squares (resulting in a total of 15).

Finally, calculate the area of one of the squares (2cm x 2cm), which results in 4cm². As you have 15 total squares, multiply 4cm² by that to get the final answer of 60cm².

The augmented matrix is,

[tex]\left(\begin{array}{ccccc}1&-1&-4&|&5\\2&0&2&|&0\\4&1&1&|&3\end{array}\right)[/tex]

We have given system of linear equation is,

[tex]x - y - 4z = 5,2x + 2z = 0 ,4x +y +z = 3.[/tex]

In an augmented matrix, each row represents one equation in the system and each column represents coefficients (with signs) of variables or the constant terms.

So, the first row is

[tex]1\ -1\ -4\ 5[/tex]

the second row is

[tex]2\ 0\ 2\ 0[/tex]

and the third row is

[tex]4\ 1\ 1\ 3[/tex]

Therefore the augmented matrix for this linear system is,

[tex]\left(\begin{array}{ccccc}1&-1&-4&|&5\\2&0&2&|&0\\4&1&1&|&3\end{array}\right)[/tex]

The augmented matrix for the given linear equations will be constructed as follows

[tex]\left[\begin{array}{ccc}1&-1&-4\\2&0&2\\4&1&1\end{array}\right] \left[\begin{array}{ccc}5&\\0\\3\end{array}\right][/tex]

The augmented matrix is generally a matrix form of the given linear equations and the coefficient of the variables are arranged in the form of a matrix.

The given equation has three variables so the matrix form will be of [tex]3\times3[/tex]

The given linear equations are

[tex]x-y-4z=5\\2x+0y+2z=0\\4x+y+z=3[/tex]

From the above equations, we will make an augmented matrix.

[tex]\left[\begin{array}{ccc}1&-1&-4\\2&0&2\\4&1&1\end{array}\right] \left[\begin{array}{ccc}5&\\0\\3\end{array}\right][/tex]

The first equation will be followed by the first row of the matrix and the rest will be followed the same.

Thus the augmented matrix for the given linear equations will be constructed as follows
