Answer:
{9} Slope: -1
Y-intercept = 0
Step-by-step explanation:
Slope-----
Recall slope-intercept form
y=mx+b, with slope m and a y-intercept of b. With this in mind, we can rewrite our equation as y=−x+0
We see that our slope, or coefficient on x, is −1.
Y-intercept-----
We can rewrite this equation as:y=1x+0
The slope-intercept form of a linear equation is: y=mx+b
Where m is the slope and b is the y-intercept value.
For this equation:y=1x+0
Therefore:
The slope is m=1
The y-intercept is b=0 or (0,0)
Hope this helps!
STEP 1: Compute the mean
The mean of the dataset is the sum of the elements divided by their number:
STEP 2: Compute the residuals
You have to compute the difference between every element and the mean:
Step 3: Square the residuals:
Step 4: Sum the squared the residuals:
Step 5: Divide by the number of elements in the dataset:
Step 6: Consider the square root of the result:
The formula we used is
where is the standard deviation, are the elements in the dataset, is the number of elements in the dataset, and is the mean of the dataset.
Answer:
C. 7 - 3 = 4
Step-by-step explanation:
Given
Required
The IQR
The IQR is calculated using:
Where:
Median of the upper
Median of the lower
The dataset has 7 values, so the median is: (7 + 1)/2 =8/2 = 4th position.
Split to two, we have:
The lower half has 3 data; So, the median is the 2nd position.
Hence:
The upper half has 3 data; So, the median is the 2nd position.
Hence:
So, the IQR is:
