Answer:

4.4

Step-by-step explanation:

Data set = 79, 93, 92, 86, 90

Xmean = (79 + 93 + 92 + 86 + 90)/5

= 440/5

Xmean = 88

MAD =

(79 - 88) + (93 - 88) + ( 92 - 88) + ( 86 - 88) + ( 90 - 88)/ 5

=

(9) + (5) + (4) + (2) + (2)/ 5

=

22/5

Harrizon [31]

Answer:

Total 164 legs.

Step-by-step explanation:

The unicorns : stardust, umo, windthorn and highflyer are enjoying themselves playing in the forest.

They notice 8 spiders, one spider has 8 legs = 8 × 8 = 64 legs

there are 5 cockroaches, one cockroach has 6 legs = 5 × 6 = 30 legs

7 bees, one bee has 6 legs = 7 × 6 = 42 legs

3 deer, one deer has 4 legs = 3 × 4 = 12 legs

4 cows, one cow has 4 legs = 4 × 4 = 16 legs

Total legs of all the numbered creatures all together =

64 + 30 + 42 + 12 + 16 = 164 legs

Therefore, total legs are 164.

Nikitich [7]

Answer:

7/20

Step-by-step explanation:

10 blue marbles, 4 black marbles, 5 white marbles, and 6 red marbles = 25 marbles

25-10 = 15

There are 15 not blue marbles

P( not blue ) = not blue marbles / total = 15/25 = 3/5

keep the not blue marble

25-1 = 24 marbles left

15-1 = 14 not blue marbles

P( not blue ) = not blue marbles / total = 14/24 = 7/12

P( not blue, keep, not blue) = 3/5 * 7/12 = 21/60 = 7/20

Sever21 [200]

Answer:

Exactly one solution

4x -2y = 8

2x +y = 2

Multiply the second equation by 2

4x +2y = 4

Add the two equations together

4x -2y = 8

4x +2y = 4

-------------------

8x = 12

x = 12/8

We know there will be one solution
