Answer:
Probability = 0.502
Step-by-step explanation:
We are given the following data :
Hours Count Percent
1 18 3.44
2 55 10.50
3 81 15.46
4 109 20.80
5 88 16.79
6 66 12.60
7 39 7.44
8 17 3.24
9 17 3.24
10 19 3.63
15 15 2.86
We need to calculate the probability
P(Length of stay of exactly 1 is less than or equal to 4)
P(
) = P(Y = 1) + P(Y = 2) + P(Y = 3) + P(Y = 4)

We convert the percent into probabilities by dividing them with 100. This gave us the required probabilities.
612/6=102
check: 6x102=612
Hope this helped! :))
Answer:
The required proportion is
.
Step-by-step explanation:
Consider the provided information.
The price of a recipe-book was reduced from $24.50 to$17.95.
The original price is 24.50
Reduced price is 17.95.
Let p represents the percent decrease in price of the book.

Now substitute the respective values in the above formula.


Hence, the required proportion is
.
