Answer:
5 cm
Step-by-step explanation:
Let's assume this is a number line were given.
Distance of S from 0 = 4 units
Distance of T from 0 = 9 units 
Length of ST = the difference between T and S
ST = |9 - 4| = 5 units = 5 cm
This means S and T are 5 cm apart.

Think about it, 64 band members split equally into 8 rows. Sounds like division, right? If we're going to split them into each row, that would be eight members for each of the eight rows. 
So the answer is that 8 members was in each row.
        
                    
             
        
        
        
If he sang the same number of songs each month, he sang 80 songs per month. 
960/12 (months) = 80 (songs per month)
        
             
        
        
        
Answer:
 We conclude that garbage collector's average picking is more than four tons of garbage per day.
Step-by-step explanation:
We are given the following information n the question:
First, we design the null and the alternate hypothesis
 
Significance level = 5% = 0.05
P-value = 0.04
- The p-value is the probability of obtaining the observed results of a test, assuming that the null hypothesis is correct.
 
- P values evaluate how well the sample data support that the null hypothesis is true. 
 - P-value is a measure or indicator that helps us to know that whether the sample belongs to the population or not.
 - Null hypothesis states that the sample belongs to the population.
 
- A high p-values states that the null hypothesis is true ad the sample belongs to the population.ll.
 
- A low p-value suggests that sample provides enough evidence that you the null hypothesis is not true and the sample does not belong to the population.
 - We compare p-value to significance level to obtain our result.
 
Here,
p-value = 0.04 < Significance level = 0.05
Since the p-value is lower than the significance level, we fail to accept the null hypothesis and reject it. That is there were enough evidence to support the fact that sample does not belong to the population and we conclude that garbage collector's average picking is more than four tons of garbage per day.
