Answer:
182.41
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean  and standard deviation
 and standard deviation  , the zscore of a measure X is given by:
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

40th percentile
Value of X when Z has a pvalue of 0.4. So X when Z = -0.253.




So the answer is 182.41.
 
        
             
        
        
        
Hey!
1 car is $3.83.
3 cars is $3.83 × 3
3.83 × 3 = 11.49
Shipping fee is $4.55. Add that to the price of the 3 cars
11.49 + 4.55 = 16.04
The girls share the cost equally. Divide by 2
16.04 ÷ 2 = 8.02

 
        
                    
             
        
        
        
1.65 rounded to the nearest whole number is 2
