For a standard normal distribution, if P (z less-than-or-equal-to a) = 0. 7116, what is the value of P (z greater-than-or-equal-to a)? 0. 2116 0. 2884 0. 7116 0. 7884.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3
