during the last four days lee studied for 3 hours, 2.5 hours, 1.5 hours, and 3 hours. what is his median study time
1 answer:
a, b, c, and d stand for each of the variables in the equation.
x stands for the number of variables in the equation
Whenever you are finding the Median, first add all variables. You must then divide the sum of those variable by the number of variables involved.
In this case:
Answer: Lee studied a median of 2.5 hours over the last 4 days.

Answer:
y = 2x - 1
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 ) = A(4, 7) and (x₂, y₂ ) = B(2,3)
m = =
= 2 , thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 3), then
3 = 4 + c ⇒ c = 3 - 4 = - 1
y = 2x - 1 ← equation of line
