Answer:
$9
Step-by-step explanation:
'Jonathan and 5 friends' would equal <u>6 people paying</u>
Since the total amount was 54 dollars, the equation will be:
$54 ÷ 6 friends
54 divided by 6 is $9
Check:
6 x 9 = 54
 
        
             
        
        
        
Answer:
The answer is "Option A and Option B"
Step-by-step explanation:
In question 1:
The fixed cost=2621.21  
The unit variable cost=35.58  
Calculating the total cost for 45 boat slips:

In question 2:
It is the pure fixed costs that remain consistent in total regardless of dynamic loads. An overall cost B both for 1000 and 2000 unit is unchanged, therefore the Cost B is a fixed sum.
 
        
             
        
        
        
Answer: (a) P(no A) = 0.935
               (b) P(A and B and C) = 0.0005
               (c) P(D or F) = 0.379
               (d) P(A or B) = 0.31
Step-by-step explanation: <u>Pareto</u> <u>Chart</u> demonstrates a relationship between two quantities, in a way that a relative change in one results in a change in the other.
The Pareto chart below shows the number of people and which category they qualified each public school.
(a) The probability of a person not giving an A is the difference between total probability (1) and probability of giving an A:
P(no A) = 
P(no A) = 1 - 0.065
P(no A) = 0.935
b) Probability of a grade better than D, is the product of the probabilities of an A, an B and an C:
P(A and B and C) = 
P(A and B and C) = 
P(A and B and C) = 0.0005
c) Probability of an D or an F is the sum of probabilities of an D and of an F:
P(D or F) = 
P(D or F) = 
P(D or F) = 0.379
d) Probability of an A or B is also the sum of probabilities of an A and of an B:
P(A or B) = 
P(A or B) = 
P(A or B) = 0.31
 
        
             
        
        
        
Answer: 67 
Step-by-step explanation:
3x^2 + 5x + 25
x = 3
3(3)^2 + 5(3) + 25 
3^2 = 9
3(9) + 5(3) + 25
3 * 9 = 27
27 + 5(3) + 25
5 * 3 = 15
27 + 15 + 25 
27 + 15 = 42
42 + 25 = 67
