Step-by-step explanation:
S = 93 log (d) + 65; S = wind speed; d = distance traveled by tornado
A) tornado travels 130 miles = d; find S
S = 93 log10(130) + 65
S = 261.6 mph rounds up to 262 mph
 
        
                    
             
        
        
        
Answer:
The probability that at least one is a boy is 0.525
Step-by-step explanation:
P(Baby being a girl) = 0.475
Now, if A is any arbitrary event . Then: 
as we know P(A)+ P(not A) = 1
⇒ P(A not happening)  = 1 - P(A event happening)
Also,  P( baby not being a girl) = P(baby being a boy)
So,  P(baby being a boy)  = 1 - P( baby being a  girl)
                                           = 1 - 0.475   = 0.525
Hence,  the probability that at least one is a boy is 0.525
 
        
             
        
        
        
Answer:
Step-by-step explanation:
<u>The ratio of corresponding sides of similar figures is same:</u>
- 3x/20 = (4x + 2)/(20 + 8)
- 3x/20 = (2x + 1) / 14
- 3x(14) = (2x + 1)(20)
- 42x = 40x + 20
- 2x = 20
- x = 10
