Answer:  n = 5

<u>Step-by-step explanation:</u>

\dfrac{n+1}{9}=\dfrac{n+7}{18}\\\\\\\underline{\text{Clear the denominator:}}\\18\bigg(\dfrac{n+1}{9}\bigg)=18\bigg(\dfrac{n+7}{18}\bigg)\\\\\\\underline{\text{Simplify and solve for n:}}\\2(n+1)=n+7\\2n+2=n+7\\n+2=7\\\large\boxed{n=5}

Answer:

5

Step-by-step explanation:

  • 9/(n+1)= 18/(n+7)
  • 1/(n+1)=2/(n+7)
  • n+7= 2(n+1)  cross multiplication
  • n+7=2n+2
  • 2n-n= 7-2
  • n=5

Find the MAD of this set of data.
barxatty [35]

Answer:

2.8

Step-by-step explanation:

The given data set is;

6, 12, 10, 9, 8, 6, 2, 4, 8, 15

The mean of this set is;

\bar X=\frac{\sum x}{n}

\bar X=\frac{6+12+10+9+8+6+2+4+8+15}{10}

\bar X=\frac{80}{10}=8

The mean absolute deviation is given by

M.A.D=\frac{\sum |x-\bar X|}{n}

M.A.D=\frac{|6-8|+|12-8|+|10-8|+|9-8|+|8-8|+|6-8|+|2-8|+|4-8|+|8-8|+|15-8|}{10}

M.A.D=\frac{2+4+2+1+0+2+6+4+0+7}{10}

M.A.D=\frac{28}{10}

M.A.D=2.8

Find the slope of the line passing through the points <br> , −8−3<br> and <br> , −34<br> .
alukav5142 [94]

Slope of the line passing through two points <span><span>P=<span>(<span><span>x1</span>,<span>y1</span></span>) </span></span></span>and <span><span>Q=<span>(<span><span>x2</span>,<span>y2</span></span>)</span></span></span> is given by <span><span>m=<span><span><span>y2</span>−<span>y1/</span></span><span><span>x2</span>−<span>x1</span></span></span></span></span>.

We have that <span><span><span>x1</span>=−8</span></span>, <span><span><span>y1</span>=−3</span></span>, <span><span><span>x2</span>=−3</span></span>, <span><span><span>y2</span>=4</span></span>.

Plug given values into formula for slope: <span><span>m=<span><span><span>(4)</span>−<span>(<span>−3</span>)/</span></span><span><span>(<span>−3</span>)</span>−<span>(<span>−8</span>)</span></span></span>=<span>7/5</span></span></span>.

Now y-intercept is <span><span>b=<span>y1</span>−m⋅<span>x1</span></span></span> .

<span><span>b=−3−<span>(<span>7/5</span>)</span>⋅<span>(<span>−8</span>)</span>=<span>41/5.</span></span></span>

Finally, equation of the line can be written in the form <span><span>y=mx+b</span></span>.

<span><span>y=<span>7/5</span>x+<span>41/5</span></span></span>
