Answer:
D 98°
Step-by-step explanation:
180-82 = 98 or the long way
3x+5 = 180-82
3x = 93
x = 31
3(31) + 5 = 98
 
        
             
        
        
        
Answer:
0.84
Step-by-step explanation:
1 - 0.4(0.4) = 1 - 0.16 = 0.84
Simply take the probability of the the outcome that is not " at least 1 win", which is the probability of 2 losses;
To find the probability multiply the probabilities along the branches.

Answer:
I assume you know Arithmetic Progression .
so, we have to find the first and last 4-digit number divisible by 5
first = 1000 ,  last =  9990
we have a formula,    = a + (n-1)d
 = a + (n-1)d
here,  is the last 4-digit number divisible by 5.
 is the last 4-digit number divisible by 5.
n is the number of 4-digit even numbers divisible by 5 
d is the common difference between the numbers, which is 10 in this case 
a is the first 4-digit number divisible by 5
9990 = 1000 + (n-1)*10
899 = n-1
n = 900
Hence, there are 900 4-digit even numbers divisible by 5
