Answer:
Weight of the solution = 250 grams
Step-by-step explanation:
1) Consider the weight of solution as x grams.
32 % solution = 80 grams salt
32% of x = 80
(32/100)*x = 80
Solving for x:
x  = (80*100) / 32
x = 250 grams
 
        
             
        
        
        
Answer:
Interest = $ 90000
Step-by-step explanation:
Given, Principal= $15000
 Rate = 3%
 Time = 5 years
Interest = P × R × T/100
 
Therefore, Interest = 15000 × 3 × 5/100
 (dividing 100 by 5 to get 20)
 = 15000 × 3 × 20
 = 90000

Answer:
4x^2 and 5x or 4 and 5, not sure how it goes, but it's for sure 4 and 5
Step-by-step explanation:
a factor is something which is multiplied by something else soooo I'd say it's 4x^2 and 5x because they are supposed to be multiplied by whatever x is
 
        
                    
             
        
        
        
Answer:
0.8753
Step-by-step explanation:
Calculate the probability that your job will be ready before 10.01 am
Here, the parameter of an Exponential is E(X)=12
Now, to calculate the third job probability, it follows Poisson Distribution with parameter 1/λ
Therefore, E(Y) =1/12
Here, The third job will be ready for 10:01 AM, then E(Y)=61/12
Therefore, the required probability is 

=1- POISSON(3,5,true)
=1-0.1246
=0.8753
