Answer:
a) Number of laundry he can do with this box = 78 laundries.
b) Price he paying for each load = 0.256 $
Explanation:
Total scoop contained in detergent box = 195 scoops.
Scoops used by each load of laundry = scoops = 2.5 scoops
Number of laundry he can do with this box = 195/2.5 = 78 laundries.
Price of detergent box = 19.99 $
Price he paying for each load = Total price/ Number of loads
= 19.99/78
= 0.256 $
Answer:
The definite integral expressing the total quantity of oil, 'V', which leaks out of the tanker in the first hour is given as follows;
Step-by-step explanation:
From the question, we have;
The rate at which oil leaks out of the tanker, r = f(t)
The unit of the oil leak = Liters per minute
The unit of t = Minutes
Therefore, we have;
The definite integral expressing the total quantity, 'V', of oil which leaks out of the tanker in the first hour is given as follows;
Therefore, we have;
Answer:

Step-by-step explanation:
You are given a two-way table:
Check all options:
A. The probability that a randomly selected adult chose Hawaii as the preferred destination.
Number of people who choose Hawaii = 147
Number of teenagers who choose Hawaii = 50
Probability is
False
B. The probability that a randomly selected child chose Florida as the preferred destination.
Number of childs = 109
Number of childs who prefer Florida = 62
The probability is
False
C. The probability that a randomly selected person who chose Mexico as the preferred destination is a child.
Number of people who choose Mexico = 113
Number of people who choose Mexico and is a child = 14
The probability is
True
Answer:
The probability is 0.2650
Step-by-step explanation:
Let's start assuming that men and women come in at the same rate.
Let's define the following random variables :
X : ''Number of people that enter a drugstore''
M : ''Number of men that enter a drugstore''
W : ''Number of women that enter a drugstore''
The number of people will be the number of men plus the number of women
⇒
X = M + W
We are also assuming that M and W are independent random variables.
X ~ Po (10)
M ~ Po (λ1)
W ~ Po (λ2)
λ1 = λ2 because we assumed that men and women come in at the same rate.
λ1 = λ2 = λ
λ1 + λ2 = λ + λ ⇒ 2λ = 10 ⇒ λ = 5
M ~ Po (5)
W ~ Po (5)
Because X is the sum of two independent Poisson random variables.
We are looking for :
Because we assume independence.
because is a Poisson random variable with λ = 5
