Answer:
The full price was $176.
Step-by-step explanation:
To solve this problem, solve backwards. Since the total is $100, you subtract $12 from it, which leaves you with $88. You then multiply $88 by 2 (for the half price).
Answer:
To find the solutions to the following questions what you would need to do is to factor out the common variable or g. Which would be the following:
g(g-4) = 45
g = 45
g2 = 49
This is more of the erraneous way to find the solution for the original one factor the expression
Step-by-step explanation:
g2 - 4g - 45 = 0
(g-9)(g+5) = 0
you can figure out what the 2 roots would be.
Answer:
a) 0.5514
b) 0.0058
Step-by-step explanation:
Data provided in the question:
Probability that the the selected person is righthanded, P(R) = 0.82
Therefore,
Probability that the the selected person is not righthanded, P(R') = 1 - 0.82
= 0.18
Now,
a. They are all right-handed
P (They are all right-handed) = P(R) × P(R) × P(R)
= 0.82 × 0.82 × 0.82
= 0.5514
b) None of them is right-handed
P (None of them is right-handed) = P(R') × P(R') × P(R')
= 0.18 × 0.18 × 0.18
= 0.0058
