Answer:

<em>Mean Absolute deviation for (set 1): 4</em>

<em>Mean Absolute deviation for (set 2): 9</em>

Set 2 has a lower (MAD) mean absolute deviation that Set 1.

Step-by-step explanation:

(set 1)

Mean: 80 + 82 + 90 = 252/3 = 84

84 - 80 = 4

84 - 82 = 2

84 - 90 = 6

Mean Absolute Deviation: 2 + 4 + 6 = 12/3 = 4

(set 2)

Mean: 60 + 80 + 82 + 90 = 312/4 = 78

78 - 60 = 18

78 - 80 = 2

78 - 82 = 4

78 - 90 = 12

Mean Absolute Deviation: 2 + 4 + 12 + 18 = 36/4 = 9

What are the ordered pairs of the solutions for this system of equations?
Scorpion4ik [409]

Answer:

<em>( 4, 11 ) , ( - 4, 27 ) </em>

Step-by-step explanation:

f(x) = x² - 2x + 3

f(x) = - 2x + 19

x² - 2x + 3 = - 2x + 19

x² - 16 = 0

( x + 4 )( x - 4 ) = 0

x_{1} = - 4

x_{2} = 4

f(x) = y_{1} = - 2( - 4 ) + 19 = 27

y_{1} = 27

f(x) = y_{2} = - 2( 4 ) + 19 = 11

y_{2} = 11

<em>( 4, 11 ) , ( - 4, 27 )</em>

Explain how you might use the properties of multiplication to solve 5 × 120 × 6.232 mentally. Then solve.
zysi [14]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

In this question, we apply the associative property that calculates the given  value, which can be defined as follows:  

Rule:

\bold{\to (A\times B)\times C=  A \times (B\times C)}

Let,

A= 5\\B=120\\C=6.232

put the value in the above rule:

Solve L.H.S part:

\to (5\times 120)\times 6.232\\\\\to (600)\times 6.232\\\\\to 3,739.2

Solve R.H.S part:

\to 5 \times (120 \times 6.232)\\\\\to 5 \times 747.84\\\\\to 3,739.2

So, L.H.S=R.H.S

I got 1.1... is that right?
kap26 [50]

No, the answer is 2

X=2

This is because if we multiply the number by x which is 2

so DST is 110, and RSD is 44, so that is 154, and if we do it with RST we also get 154

So the correct answer is X=2
