Answer:
1.15%
Step-by-step explanation:
To get the probability of m  independent events you multiply the individual probability of each event. In this case we have m independent events, each one with the same probability, therefore:
 

This is a particlar scenario of binomial distribution problem. So the binomial distribution questions are about the number of success of m independent events, where every individual event has the same p probability. In the question we have 20 events and each event has a probability of 80%. The binomial distribution formula is:

n is the number of events
k is the number of success
p is the probability of each individual event
 is the binomial coefficient
 is the binomial coefficient
the binomial coefficient allows to find the subsets of k elements in a set of n elements.  In this case there is only one subset possible since the only way to get 20 of 20 correct questions is to getting right all questions (for getting 19 of 20 questions there are many ways, for example getting the first question wrong and all the other questions right, or getting second questions wrong and all the other questions right, etc).

therefore, for this questions we have:

 
        
             
        
        
        
Answer:
<x = 20°
Step-by-step explanation:
<x = 1/2(arc UT - arc SV)
<x = 1/2(65° - 25°)
<x = 1/2 (40°)
<x = 20°
 
        
             
        
        
        
Answer:
Charlotte spend  of day trying on jeans
 of day trying on jeans
Step-by-step explanation:
Charlotte spent part of day on shopping = 
She spent part of shopping time on trying jeans =
We are supposed to find What fraction of the day did Charlotte spend trying on jeans.
She spent fraction of the day in trying jeans = 
She spent fraction of the day in trying jeans = 
Hence Charlotte spend  of day trying on jeans
 of day trying on jeans
 
        
             
        
        
        
Your answer would be 10.6
