You did NOT list the interest rate so I can't calculate anything.
However, if you look at the attached formula,
principal = $650
n = 52
years = 8
It means 68% of all the final scores went in bewtween 80 and 90 percent
To solve do the base (2.2) multiply by the height (3.8) and then divide the answer I get from that by 2
Answer:
y = 2x - 8
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 = ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
with (x₁, y₁ ) = (- 1, - 10) and (x₂, y₂ ) = (5, 2)
m =
=
=
= 2 , then
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (5, 2 ) , then
2 = 10 + c ⇒ c = 2 - 10 = - 8
y = 2x - 8 ← equation of line
