5. the average weight of adult male bison in a particular federal wildlife preserve is 1550
pounds with a standard deviation of 280 pounds.
find the weight of an adult bull whose z-score is - 2.
a) 2110 lb.
b) 990 lb.
c) 1270 lb.
d) 1550 lb.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

c. 1,233 miles
