100 Points Assume all datasets mentioned here have a normal distribution.

A group of basketball players has an average weight of 230 pounds with a standard deviation of 25 pounds.

Roughly what percentage of the player's weigh more than 255 pounds?

What percentage of players weigh more than 280 pounds?

What percentage of players weigh more than 205 pounds?

If we have a group of 500 basketball players, how many of them probably weigh less than 180 pounds?

40 x 50 = 2000

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
