Answer:
Linear equation
Step-by-step explanation:
f(x) = 2x + 15
Linear because constant increase
The area of a triangle is A = (b*h)/2:
(5 * 8)/2 = 20
Answer: 0.68
Step-by-step explanation:
given data:
ABC market share = 30%
number of customers surveyed = 800
probability that more than 32% prefers ABC
Solution:
32% of 800
= 256 persons
p ( x ≥ 256 )
= 1 - ( 256/800 )
= 1 - 0.32
= 0.68
the probabiliy that more than 32% of those who carried out the survey would prefer ABC brand is 0.68.
Divide both sides by f then cancel out
