Answer:

Step-by-step explanation:
Given

Required
Determine the roots
To get the root of the function, then f(b) must be 0;
i.e. f(b) = 0
So, the expression becomes

Add 75 to both sides


Take square roots of both sides


Reorder

Expand 75 as a product of 25 and 3

Split the expression




The options are not clear enough; however the roots of the equation are 
Answer:
0.18431525 = 18.4%
Step-by-step explanation:
General Formula :
total trials Cn⋅p(success)^n⋅p(fail)^total−n
1198144* (.0218)^3 * (1-.0218)^191
y - 4 = -2 ( x - ( -11)) which would simplify to y - 4 = -2 ( x + 11) !!
(1/8), (2/8), (3/8), (4/8), (5/8), (6/8), (7/8)
if u want, 2/8=1/4, 4/8=1/2, 6/8=3/4
Answer:
-15
Step-by-step explanation:
-3(-4-5x)= -18
12+15x= -18-12
15x= -30
x= -30÷15
x= -15
