Answer:
Answer b)
Step-by-step explanation:
In the sequence 0, 5, 10, 15,...
5 is added to each term in order to get the next one. Therefore the next three terms would be; 20, 25, 30.
This agrees with answer b) in the list of possible answers.
 
        
             
        
        
        
Answer:
1.25x10^2
Step-by-step explanation:
5x5^2
5x5x5=125
125=1.25x10^2
Therefore 5x5^2=1.25x10^2
 
        
                    
             
        
        
        
Let x = # of Republicans
x + 4 = # of Democrats
x + x + 4 = 100
x = 48 
48 + 4 = 52
There are 52 Democrats and 48 Republicans. 
 
        
             
        
        
        
Answer: 0.5
Step-by-step explanation:
Binomial probability formula :-
 , where P(x) is the probability of getting success in x trials , n is the total trials and p is the probability of getting success in each trial.
, where P(x) is the probability of getting success in x trials , n is the total trials and p is the probability of getting success in each trial.
Given : The probability that the adults follow more than one game = 0.30
Then , q= 1-p = 1-0.30=0.70
The number of adults surveyed : n= 15
Let X be represents the adults who follow more than one sport. 
Then , the probability that fewer than 4 of them will say that football is their favorite sport,

Hence, the probability rounded to the nearest tenth that fewer than 4 of them will say that football is their favorite sport =0.5
