Answer:
The Theoretical probability is 1/6.
The experimental probability is 1/5
Step-by-step explanation:
Given
Rolls: 100
Outcome of 3 : 20
Required
Which of the options is true (See attachment for options)
From the attachment, we understand that the question requires that we calculate the experimental and theoretical probability.
The experimental probability (E) is calculated as thus:
The theoretical probability (T) is calculated as thus:
A cube has 6 faces, one of which is the face 3.
So, T is:
Hence, C is true
#1 is 12x² -15x
#2 is fx-9x
It should be rational

Answer:
33 inches
Step-by-step explanation:
The problem above shows a <em>"direct proportion,"</em> which means that when one quantity increases <em>(days)</em>, the other quantity increases<em> (inches of rain).</em>
Step 1: Represent the amount of rain by n.
Step 2: Setup a proportion.
= 
(where 14 refers to the number of days in 2 weeks)
Step 3: Cross multiply:
15 x 31 = 14n
465 = 14n
Step 4: Find n by dividing both sides by 14.
n = 33.21
Step 5: Round off to the nearest inch.
n = 33 inches
