Answer:

a(n) = -16b + (n - 1)(3b)

Step-by-step explanation:

First term is -6b.

Common difference is 3b; each new term is equal to the previous one, plus 3b.

Formula for this arithmetic sequence is

a(n) = -16b + (n - 1)(3b)

A cyclist travels at a speed of 20 km/hour. How far will he travels in 50 minutes?

masha68 [24]

Answer:

This is not my answer btw

Step-by-step explanation:

Given that speed(v) = 20km/h and time(t) = 50 min

We have to find distance (d)

First convert speed into m/s

v = (20*1000m)/(1*3600s)

v = (50/9) m/s

Now convert time into second

t = 50*60 = 3000 sec

As we know that

d = v*t = (50/9)*3000 = 50000/3

d = 16666.67m or 16.67km

Ans: 16666.67m or 16.67km

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

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

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

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

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

$M.A.D=2.8$
