Answer:

Step-by-step explanation:
Given
Represent Derrick's with D and Pauline's with P
For D
Registration Fee = $12
Hourly Charges = $5
For P
Registration Fee = $18
Hourly Charges = $3
Required
Represent as an inequality such that D is at most of P
First, we need to represent both as an expression:
For D

For P:

Since D is at most of P;
This implies that:

So, we have:

Answer:
The claim is not true
Step-by-step explanation:
We are given that A local retailer claims that the mean waiting time is less than 8 minutes.


A random sample of 20 waiting times has a mean of 6.3 minutes with a standard deviation of 2.1 minutes.

s = 2.1
n = 20
Since n <30 and population standard deviation is unknown
So,we will use t test
So,

t=-3.62
α = 0.01
Degree of freedom = df=n-1=20-1=19

t calculated < t critical
So, we failed to reject null hypothesis
Hence the claim is not true

Answer:
Radius was helping his father Sir Cumference.
Explanation:
The question above is related to the mathematical adventure story entitled <em>"Sir Cumference and the Dragon of Pi."</em>
Radius was the<u> son of Sir Cumference and Lady Di of Ameter</u>. One day, Sir Cumference drank a potion which turned him into a dragon. In order to restore his father's shape, radius needed to find the magic number called "pi."
In mathematics, the value of pie is more than 3<em> (3.14 to be exact)</em> and it is represented by the Greek symbol "
."
So, this explains the answer.
