420 cents for 1000 g. So 42 cents for 100 g (i crossed multiplied).
%profit=63-42/42 *100=50%
        
             
        
        
        
Answer:
Your answer will be the third function
Step-by-step explanation:
The base function you need to know is h(t)= 1/2at^2
Your acceleration in this problem is going to be gravity which they give to you, 32 feet per second squared. Since the ball is falling, it means it will have negative acceleration. Now you have the equation h(t)= -16t^2. The final step is to add the initial height from which the ball was dropped giving you: h(t)= -16t^2 +12
 
        
             
        
        
        
Answer: j=0.4
-j+0.8=-0.9j+0.76
-j+0.8+0.9j=-0.9+0.76+0.9j
-0.1j+0.8=0.76
-0.1+0.8-0.8=0.76-0.8
-0.1j=-0.04
-0.1j/-0.1=-0.04/-0.1
j=0.4
Ya have a good day.
 
        
                    
             
        
        
        
Answer: The distribution of the data set is positively skewed.
<u>Explanation: </u>
In order to see whether the given data set is symmetric, positively skewed or negatively skewed, we will find the mean, median and mode of the given data set.
For symmetric distribution, 
For positively skewed distribution, 
For negatively skewed distribution, 
The mean of the given data set is given below:

                 
                 
Now, the Median is:
To find the median we need to sort the data in ascending order as:


                    
                    
                    
                    

The mode is the most frequently occurring observation. Therefore the mode is:

Since the  , therefore the distribution of the given data set is positively skewed.
, therefore the distribution of the given data set is positively skewed.
