You just find out what the missing variable is by subtracting 88 from 107 on the first one. You do the same for the last too as-well, but just insert the numbers that they say.

The z-score tells you how many standard deviations from the mean. 
<span>1.5 * 3.6 = 5.4 miles </span>
<span>So anything within 5.4 miles of the average (29). </span>
<span>The range would be: </span>
<span>29 - 5.4 = 23.6 </span>
<span>to: </span>
<span>29 + 5.4 = 34.4 </span>
<span>23.6 ≤ x ≤ 34.4 </span>
<span>Answer: </span>
<span>B) 24 miles</span>
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
The answer is actually
Let:
S=1+2+3+4+5+6+7+8+9+n
We know the answer to the following infinite sum:
S2=1-1+1-1+1-1+1-1+1-1+1-1+1-....= - 1/2
We can therefore solve for this sum:
S3=1-2+3-4+5-6+7-8+9-....
We add them:
S3=      1-2+3-4+5-6+7-8...
S3=       +1-2+3-4+5-6+7-8...
         ________________
2S3=    1-1+1-1+1-1+1-1+1-....
Therefore:
2S3=S2=

Answer:The number of milk chocolates are 18 and the number of dark chocolates are 24.</h2>
Step-by-step explanation:
Let the number of milk chocolates be  .
.
Let the number of dark chocolates be  .
.
Given that the box contains the milk and dark chocolates in the ratio  .
.
So, ...(i)
               ...(i)
Given that the total number of chocolates are  .
.
So, .                                   ...(ii)
.                                   ...(ii)
Using (i) and (ii),




So,the number of milk chocolates are  and the number of dark chocolates are
 and the number of dark chocolates are  .
.
 
        
        
        
Definition: A histogram visualises the distribution of data over a continuous interval or certain time period. Each bar in a histogram represents the tabulated frequency at each interval. 
According to the given histogram,
0-20 years occur 15 times,
21-40 years occur 40 times,
41-60 years occur 40 times,
61-80 years occur 15 times.
This shows that the data is symmetrical and the majority of the attendees were between the ages of 21 and 60 (40 times).
Answer: correct choice is B.
