Answer:
31
Step-by-step explanation:
Substitute -10 for x in b(x)=|x+41|, obtaining f(-10) = |-10 + 41|.  This result simplifies to f(-10) = |31| = 31
 
        
             
        
        
        
there are 4 kings and 4 queens in a deck
 chance of getting a king is 1/52
 chance of getting a queen without the king being put back would be 1/51
1/52 x 1/51 = 1/2652 probability
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Given that the  time to complete a standardized exam is approximately normal with a mean of 70 minutes and a standard deviation of 10 minutes.
P(completing exam before 1 hour)
= P(less than an hour) = P(X<60)
=P(Z< )
)
=0.5-0.34=0.16
i.e. 16% of students completed the standardized exam.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
(3x + 2) + (x - 4) = 90
                4x - 2 = 90
                      4x = 92
                        x = 23
m∠A = (3(23) + 2) = 71°
