With these two qestions:
the tables below show four sets of data:
set a
x 1 2 3 4 5 6 7 8 9
y 10 9 8 7 6 5 4 3 2
set b
x 1 2 3 4 5 6 7 8 9
y 3 4 5 6 7 8 9 10 11
set c
x 1 2 3 4 5 6 7 8 9
y 8 6 5 4 3.5 3 2.5 2 2
set d
x 1 2 3 4 5 6 7 8 9
y 1 2.5 2.5 3 4 5 6 8 9
for which set of data will the scatter plot represent a positive linear association between x and y?
set a
set b
set c
set d

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

4.

step-by-step explanation:

it have the same area.brainliest

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
