Let us denote the number of tiles by 

.
In the first store, if Darin bought 

 tiles, he would need to spend:                        

 (measured in $)
In the second store, if Darin bought 

 tiles, he would need to spend:                        

 (measured in $)
For the cost to be the same at both stores, it means (measured in $)                                           

Moving 

 over to the left hand side and changing signs:                                            
 
                                             
                                             
                                            
 tiles
Let's check. If he buys 60 tiles in the first store, he spends:
                              $0.79×60 + $24 = $47.40 + $24 = $71.40
If he buys 60 tiles in the second store, he spends:
                                               $1.19×60 = $71.40
∴
 Darin needs to buy 60 tiles for the cost to be the same at both stores.

Answer:
p=18
Step-by-step explanation:
p+12=30 
subtract 12 from each side
p=18
 
        
                    
             
        
        
        
First, we are going to find if the function is odd or even. Remember that we can determine if a function is odd of even from its graph by looking at its ends; if both ends go to the same the direction, the function is even. If both ends go to opposite directions, the function is odd. At both ends, the graph of our function go towards the same direction, minus infinity, so we can conclude that our function is even.
Next, we are going to find the possible degree of our function. Remember that the possible degree of a function is the number of x-intercepts.
We can infer from our graph that the function intercepts the x-axis at least 6 times.
We can conclude that the correct answer is: even degrees of 6 or greater.
        
             
        
        
        
Answer:
91.63 cm is the interior length of the bassinet to ensure that 99 percent of newborn babies will fit, with a safety margin of 15 cm on each end of the bassinet.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 50 cm
Standard Deviation, σ = 5 cm
We are given that the distribution of  length of a newborn baby is a bell shaped distribution that is a normal distribution.
Formula:

 P(X<x) = 0.99
We have to find the value of x such that the probability is 0.99
P(X < x)  
 
  
Calculation the value from standard normal table, we have,  

 
  
Thus, 99% of newborn babies will have a length of 61.63 cm or less.
There is a safety margin of 15 cm on each end of the bassinet
Length of bassinet =
