Given:


Since R is the midpoint of the line, we can set XR equal to RY and solve for x.





Now we know what x is. We can plug in x to RY and XR and then add it all together to find XY. Let's find XR:


Let's find RY now:



Since we know that:

We can plug in our answers:

Final answer:

Answer:
(a) 169
(b) 341
(c) 125
(d) 87
Step-by-step explanation:
Consider the Venn diagram below.
The total number of shoppers surveyed is, <em>N</em> = 428.
Number of shoppers who made a purchase, <em>n</em> (P) = 216
Number of shoppers who were satisfied with the service they received,
<em>n</em> (S) = 294
Number of shoppers who made a purchase but were not satisfied with the service,
= 47
(a)
The number of shoppers who made a purchase and were satisfied with the service = <em>n</em> (S ∩ P)

(b)
The numbers of shoppers who made a purchase or were satisfied with the service = <em>n</em> (P ∪ S)

(c)
The numbers of shoppers who were satisfied with the service but did not make a purchase = 

(d)
The number of shoppers who were not satisfied and did not make a purchase = 

Answer:I think it’s 100
