Answer:
A, B
Step-by-step explanation:
The Y-axis is plotting only the downstream values this particular river is an outlier on the y-axis. What is an outlier? An outlier is a entry that varies greatly from the rest of the entries. This variation could be lower or higher than the average so one answer is B. A residual is the offset of a point in respect to its regression line (line of best fit) having a high residual means that it's a outlier so A is also correct.
Hope this helps!

If the perimeter of a rectangular picture frame must be less than 180 in., and the width is 26 in., what must the height h of the frame be?
Answer:
The height must be less than 64in.
Step-by-step explanation:
The formula for the perimeter of a rectangle is:
P=2*W+2*H
Where
P : Perimeter
W: Width
H: Length
So the for a perimeter less the 180in.
180>2*26+2*H
180>52+2H
180-52>2H
128>2H
H<64
So the height must be less than 64in.
There is an increase in total participants.
The unitarymethod is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
number of boys = 28
Number of girls = 16
Total participants = 28 + 16 = 44
Now, there is decrease in number of boys by 8%
= 28- 8% x 28
=28- 8/100 x 28
=28 - 0.08*28
=28 -2.24
= 25.76
and, there is 19% increase in number of girls
=16 + 0.19 x 16
=16 + 3.04
=19.04
So, total participants = 25.76 + 19.04
= 44.8
Hence, there is an increase in total participants.
