vladimir2022 [97]2 years ago
3 0

Answer:

Lin was better than Clare

Step-by-step explanation:

<h3>Given</h3>

<u>Clare </u>

  • mean: 2,000 grams
  • MAD: 275 grams
  • median: 2,000 grams
  • IQR: 500 grams

<u>Lin </u>

  • mean: 2,000 grams
  • MAD: 225 grams
  • median: 1,950 grams
  • IQR: 350 grams
<h3 /><h3>Question</h3>
  • Which student was better at estimating the mass of the objects?
<h3 /><h3>Solution</h3>

<u>Comparing data for both Clare and Lin, we can see that:</u>

  • mean - is same 2000 grams for both
  • median - almost same, 2000 grams vs 1950 grams
  • MAD - 275 grams vs 225 grams
  • IQR - 500 grams vs 350 grams

<u>Conclusion</u>

  • Lin was better at estimating than Clare

<u>Reason</u>

  • Both students had  measures of center (mean and median) very close to 2000 grams
  • Lin got less  variable responses as  both the MAD and IQR were lower than Clare got

Solve the given system of equations using either Gaussian or Gauss-Jordan elimination. (If there is no solution, enter NO SOLUTI
cricket20 [7]

Answer:

The system has infinitely many solutions

\begin{array}{ccc}x_1&=&-x_3\\x_2&=&-x_3\\x_3&=&arbitrary\end{array}

Step-by-step explanation:

Gauss–Jordan elimination is a method of solving a linear system of equations. This is done by transforming the system's augmented matrix into reduced row-echelon form by means of row operations.

An Augmented matrix, each row represents one equation in the system and each column represents a variable or the constant terms.

There are three elementary matrix row operations:

  1. Switch any two rows
  2. Multiply a row by a nonzero constant
  3. Add one row to another

To solve the following system

\begin{array}{ccccc}x_1&-3x_2&-2x_3&=&0\\-x_1&2x_2&x_3&=&0\\2x_1&+3x_2&+5x_3&=&0\end{array}

Step 1: Transform the augmented matrix to the reduced row echelon form

\left[ \begin{array}{cccc} 1 & -3 & -2 & 0 \\\\ -1 & 2 & 1 & 0 \\\\ 2 & 3 & 5 & 0 \end{array} \right]

This matrix can be transformed by a sequence of elementary row operations

Row Operation 1: add 1 times the 1st row to the 2nd row

Row Operation 2: add -2 times the 1st row to the 3rd row

Row Operation 3: multiply the 2nd row by -1

Row Operation 4: add -9 times the 2nd row to the 3rd row

Row Operation 5: add 3 times the 2nd row to the 1st row

to the matrix

\left[ \begin{array}{cccc} 1 & 0 & 1 & 0 \\\\ 0 & 1 & 1 & 0 \\\\ 0 & 0 & 0 & 0 \end{array} \right]

The reduced row echelon form of the augmented matrix is

\left[ \begin{array}{cccc} 1 & 0 & 1 & 0 \\\\ 0 & 1 & 1 & 0 \\\\ 0 & 0 & 0 & 0 \end{array} \right]

which corresponds to the system

\begin{array}{ccccc}x_1&&-x_3&=&0\\&x_2&+x_3&=&0\\&&0&=&0\end{array}

The system has infinitely many solutions.

\begin{array}{ccc}x_1&=&-x_3\\x_2&=&-x_3\\x_3&=&arbitrary\end{array}

Write the equation of the line with a slope of 3/7 passing through the point (9,-2) in standard or slope-point form? ...?
Musya8 [376]
y-y_1=m(x-x_1)&#10;\\&#10;\\ m= \frac{3}{7} &#10;\\&#10;\\(9,-2) \Rightarrow x_1=9,y_1=-2&#10;\\&#10;\\ y-(-2)=\frac{3}{7} (x-9)&#10;\\&#10;\\y+2=\frac{3}{7}x-\frac{27}{7}&#10;\\&#10;\\y=\frac{3}{7}x-\frac{27}{7}-2&#10;\\&#10;\\y=\frac{3}{7}x-\frac{41}{7}

HEY THERE !!

As we know that cotx= 1/tanx

cot36° = 1/tan36°

=>cot36°= 1/0.726543

=>so cot 36°= 1.376382

So correct answer is option D.
