Answer:

d = 4

Step-by-step explanation:

4(3d + 23) = 12 + 32d ← distribute parenthesis on left side

12d + 92 = 12 + 32d ( subtract 32d from both sides )

- 20d + 92 = 12 ( subtract 92 from both sides )

- 20d = - 80 ( divide both sides by - 20 )

d = 4

The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.6. Approximately

Anastasy [175]

The correct answer is that the variability is 2.0 times as large.

In the first set, the MAD is 1.2.

In the second set, the MAD is 0.6.

Dividing 1.2 by 0.6 gives us a factor of 2.

Use the inequality x2−8x+6≤0 and graphing calculator, or another piece of technology, to answer Part A and Part B. Part A: What

Kryger [21]

Answer:

Part A) The zero's of the function are $x=0.84, x=7.16$

Part B) The solution set is the interval $[0.84,7.16]$

Step-by-step explanation:

we have

$x^2-8x+6\le0$

Using a graphing calculator

Part A) What are the zeros of the inequality to the nearest hundredth?

The zero's of the function are the values of x when the values of the function are equal to zero

see the attached figure

The zero's of the function are

$x=0.84, x=7.16$

Part B) What is the solution set for the inequality?

The solution set is the interval $[0.84,7.16]$

All real numbers greater than or equal to 0.84 and less than or equal to 7.16

$0.84\leq x \leq 7.16$

The best approximation for square root of 110 is

N76 [4]

The best approximation is 10 because the two closest perfect squares to 110 is 100 and 121. the one that's closest to 110 though is 100. the square root of 100 is 10.
