When is the absolute value of a difference equal to the difference of the absolute values?

1 answer:

7 0

<span>ax(d) = absolute value of the difference = ax(a-b).
d(ax) = difference of the absolute value = ax(a) - ax(b).
ax(a-b) = absolute value of (a - b).
ax(a) - ax(b) = absolute value of (a) minus absolute value of (b).

Hope this works :)</span>

Answer: Plan A is less expensive for 50 minutes. About $6 less than Plan B

At 200 minutes, both plans cost $24

Step-by-step explanation:

1.) Look at the numbers for minutes going across the bottom from left to right. Find 50. Follow the grid line up to where the blue line crosses it. (The blue line is lower than the red line so the cost is less.) Look at the numbers on the cost scale to verify the difference if someone asked. Plan A costs $6. Plab B costs $12 for 50 minutes.

2.) Look at where the Red and Blue lines intersect. That is where the plans cost the same amount of money for the same amount of minutes. Follow the grid line down from that point to find the number of minutes.

Using the mean concept, it is found that the mean difference between the call times and the company's average call time is given by:

C. 0.4

The <em>mean </em>of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.

In this problem:

The four observations are the differences between the time of each phone call and the average time.

They are: {-2.32, -1.55, 4.79, 0.68}

Hence, the mean difference is:

$M = \frac{-2.32 - 1.55 + 4.79 + 0.68}{4} = 0.4$

Hence, option C is correct.

Step-by-step explanation:

y=mx+b

6 -8

9 -7

$- 8 = 6m + b \\ - 7 = 9m + b \\ - 7 + 8 = 9m - 6m \\ 3m= 1 \\ m = \frac{1}{3} \\$

$- 8 = 6 \frac{1}{ 3} + b \\ b = - 8 - 2 \\ b = - 10 \\ y = 0.333x - 10 \\ y = \frac{x}{ 3 } - 10$
