Answer:
The modal class is 1 - 10
Step-by-step explanation:
Given
See attachment for frequency distribution table
Required
Determine the modal class
To determine the modal class, we simply look for the class with the highest frequency.
In the given frequency distribution table, class 1 - 10 has the highest frequency of 21.
<em>Hence, the modal class is 1 - 10</em>
Just take 9/9-4/9=5/9, we get 9/9 because that is how much fruit punch that there was when the container was full. Enjoy!=)
Answer:

c)
d)
Step-by-step explanation:
Let X the random variable of interest and we know that the distribution is given by:
And for this problem we can use the cumulative distribution function in order to solve the items:
Part a
We want to find this probability:
Part b
Part c
And we can calculate the probability with this difference:
Part d
Since we have a continuous distribution the the probability for an unique value would be:
Answer:
42,10
Step-by-step explanation:
let the numbers be x and y and x>y
x+2y=62
3x-y=116
multiply by 2
6x-2y=232
add the first
7x=294
x=42
from first
42+2y=62
2y=62-42=20
y=20/2=10
