One way to carry out this problem is to simply take the value that you already know, which is that 1/5 is 20 % and multiply it by 2 for 2/5 or 2 (1/5ths) and do this for all of them. There is a pattern that occurs for every increase in one out of denominator of 5.
Answer:
19.0, 19.5, 19.054, 19.0541
Step-by-step explanation:
Answer:
The probability is 0.694
Step-by-step explanation:
Let the probability of getting a car washed be
P(W) = 72% = 0.72
Let the probability of getting a car vacuumed be
P(V) = ?
Probability of getting car washed and vacuumed is P(W n V) = 50% = 0.5
From Bayes’ theorem
P(V|W) is the probability that a customer gets their car vacuumed given that they are getting it washed
So mathematically;
P(V|W) = P(V n W)/P(W)
= 0.5/0.72 = 0.694
Answer:
20
Step-by-step explanation:
- You can set this up in an algebraic equation:
- .09x=5 which translates to 9% times a variable or unknown number equals 5
- Divide both sides by .09 which turns to 55.5
- Multiply by .36 to find 36% of that number which equals 20
