It would be 9 because
16 is the q3 and 7 is the q1 and q3-q1=16-7 =9
Answer:9
Let the number of blue marbles be: x
So,
x+15=41
Therefore,
x=41-15 (transpose)
x=36
So the number of blue marbles are 36.
Answer:
x = 7.3
Step-by-step explanation:
area = base × height / 2
21.9 = 6 × x / 2
43.8 = 6x
x = 7.3
Answer:
2x +12
Step-by-step explanation:
-4x + 6x -12
Answer:
4th option
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m =
with (x₁, y₁ ) = (2, 12) and (x₂, y₂ ) = (6, 6) ← 2 points on the line
m = = = -
the line crosses the y- axis at (0, 15 ) ⇒ c = 15
y = - x + 15 ← approximate equation of line of best fit
