-5 / 3 + 4k / = -115
1 answer:
Answer:
Step-by-step explanation:
we know That l l = x when x > 0 and l x l = - x when x <0
for the given equation - 5|3 + 4k| = - 115
when 3 + 4k > 0 the equation becomes
-5(3+4k) = - 115
→ -5 · 3 - 5 · 4k = - 115
→- 20k = - 115 + 15 = - 110
→ k = - =
Again when 3 + 4k <0 the equation becomes
-5(-(3+ 4k )) = - 115
→15 + 20k = - 115
→ 20k = - 115 - 15
→ 20k = - 130
⇒ k = - = -

Step-by-step explanation:
Point Slope Form is:
When:
'm' is the slope.
is the coordinate.
We are given the slope of -1 and the coordinate of (4,-9).
So:
Using the information and replacing the values we get:
So, the line equation in point slope form should be: y+9=-1(x-4)

Answer:
The mean absolute deviation of this data is
.
Step-by-step explanation:
The mean absolute deviation (MAD) of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.
The steps to find the MAD include:
- find the mean (average)
- find the difference between each data value and the mean
- take the absolute value of each difference
- find the mean (average) of these differences
To find the mean absolute deviation of this data you must
Step 1: Calculate the mean.
Step 2: Calculate the distance between each data point and the mean and take the absolute value of each difference .
Step 3: Add the distances together.
Step 4: Divide the sum by the number of data points.
