Answer: 72
Step-by-step explanation:
From the question, we are informed that a disc jockey can play 7 records and that there are 9 records to select from for a particular segment of a radio show.
The number of ways that the program for the segment be arranged will be:
= 9! / 7!
= (9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (7 × 6 × 5 × 4 × 3 × 2 × 1)
= 9 × 8
= 72
6/11 or about 55%
To put into a fraction the total is the denominator and the 6 would be the numerator as it is the real diamond then divide the numerator by the denominator move your decimal two places round as needed
Answer:
The following graph has no solution.
Step-by-step explanation:
Since , we are given a system of inequalities as:
x+y>4
and x+y<3
So from the two in equalities we could clearly see that in one the sum of x+y>4 while in the other the sun x+y<3 which is not possible.
This could also be seen from the graph.
The graph will not have any common region and are parallel lines.
Hence, the graph has no solution.
The key here is to not worry too much and just follow PEMDAS.
Here we have the expression 
. Following PEMDAS, we complete the expression inside the parentheses first, or 
. This gives us 
or just 
Hope this helps.
Answer:
r (100) = 10*p (10)
Step-by-step explanation:
r= 100 pieces of candy
10=10
p=10 pieces of candy
r (100) = 10*p (10)
