Answer:
    24 birds
Step-by-step explanation:
Let b represent the number of birds at the shelter on Wednesday. Then the cost of care for the 41 animals is ...
   5b +7.5(41 -b) = 247.50
   -2.5b +307.50 = 247.50 . . . . . simplify
   -2.5b = -60 . . . . . . . . . . . . . . . . subtract 307.50
   b = 24 . . . . . . . . . divide by -2.5
The number of birds at the shelter on Wednesday was 24.
 
        
             
        
        
        
Answer:
GROWTH
Step-by-step explanation:
Given the Exponential function; 
A=10* 
 
As we can see in the given function above: 
the base number is 1.01 which is greater than 1 hence the quantity increases,
slowly at first and then very rapidly over its domain. The rate of growth becomes faster as time passes. 
The growth "rate" (r) is determined as b = 1 + r.
In this situation, the rate growth is = 1.01 -1  = 0.01 
Hope it will find you well. 
 
        
             
        
        
        
Answer:
<em>99.93%</em>
Step-by-step explanation:
<u>Probability of Independent Events</u>
Given the probability of success of each detector is 0.84 independently of the others, their combined success/failure probability can be computed with the product rule.
We can calculate the required probability by using the binomial distribution, but it's easier to calculate the probability of the negated event an subtract from 1.
We want to know the probability that a least one of the 4 systems detects the occurrence of theft. That probability is the sum of the probabilities that one of them, two of them, three of them or all of them succeed. The negated event is that NONE of them actually detects the theft. Being p the individual probability of success, p=0.84. Being q the probability of failure, q=0.16.
The probability that none of the systems detect the theft is

Thus, the probability that at least one of the systems detect the theft is

That means a 99.93%
 
        
             
        
        
        
First, we need to equalize the denominator. If the denominator multiplies by (x+1), so does the numerator. If the denominator multiplies by (x-1), so does the numerator.
Look into my attachment at the second row.
Second, because the first fraction and the second fraction have the same denominator, you can join them into one fraction.Look into my attachment at the third row.
Third, simplify the numerator.Look into my attachment at the fourth to the fifth row
Fourth, simplify the denominator.Look into my attachment at the sixth to the seventh row.
 
        
             
        
        
        
540-35x= y
540 is the amount she has minus 35 and x is the weeks she withdrawn the money and y is the answer.
