Step-by-step explanation:
<u>Vertical Shift of Functions</u>
Given a linear function
y = mx + b
The value of b is called the y-intercept or the y-coordinate where the line crosses the y-axis. If the function is shifted up by a value of k, then the new function is:
y' = mx + b + k
Similarily to shift the function down, the value of k is subtracted:
y''= mx + b - k
We are given the function:
1) To shift up the line, we select a value of k=10. The new shifted-up function is:
2) To shift down the line, we select a value of k=5. The new shifted-down function is:
3) To shift to the origin, we must select a specific value of k that cancels the y-intercept. We must shift down by k=2:
This new function has the y-intercept equal to 0

Step-by-step explanation:
Calculate the 25th, 50th, and 75th percentiles.
b. Calculate the interquartile range.
c. Construct a boxplot. Are there any outliers?
Reordered data:
25, 40, 52, 55, 60, 70, 70, 72, 74, 75, 75, 80, 80, 85, 85, 86, 87, 90, 92, 99
25 th percentile :
1/4 (n + 1)th, tetm
n = 20
1/4(21) = 5.25th term
(5 + 6) th term / 2
= 65
50th percentile :
1/2 (n + 1)th, tetm
n = 20
1/2(21) = 10.5th term
(10 + 11) th term / 2
= 75
75th percentile:
3/4 (n + 1)th, tetm
n = 20
3/4(21) = 15.75th term
(15 + 16) th term / 2
= 85.5
Interquartile range :
Q3 - Q1
75th percentile - 25th percentile
85.5 - 65
= 20.5
25 is an Outlier
Answer:
The equation would be and the answer is .
Step-by-step explanation:
You need to use the formula
You're points are (4,5) and (2,-6) or (4,5)(2,-6).
First: You need to label each point.
In (4,5), 4 is and 5 is .
In (2,-6), 2 is and -6 is .
Then you need to fill in the formula:
Next, you subtract: and .
You get the fraction:
Simplify if needed: can't be simplified.
Finally, you get your answer: because two negatives make a positive.
