Find the MAD of this set of data.

Mathematics
1 answer:
barxatty [35]3 years ago
5 0

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

A pyramid with a slant height 4.6 in whose triangular base measures 8 in on each side.Each altitude of the base measures of 6.9
kvasek [131]

Answer:

82.8 in²

Step-by-step explanation:

The surface area a triangular based pyramid :

Base area + 1/2(perimeter * slant height)

Base = 8 inches ; Slant height = 4.6 inches ; altitude of base measure = 6.9 inches

Base area of triangle :

1/2 * base * height

1/2 * 8 * 6.9

4 * 6.9

Base area = 27.6 in²

The perimeter, P = sum of sides ; (s1 + s2 + s3

P = 8 + 8 + 8 = 24 in

Hence,

Surface area = 27.6 in² + 1/2(24*4.6)

Surface area = 27.6 in² + (12 * 4.6) in²

Surface area = (27.6 + 55.2)

Surface area = 82.8 in²
