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 = 
The forward differences for this data is 1, 1, 1, 1, 1, 1 (since 10 - 9 = 1, 11 - 10 = 1, etc). Since we only need one iteration of differences, a linear polynomial will fit the data exactly.
Answer:
D
Step-by-step explanation:
16 ounces, she can use all the dough and still make evenly sized pizzas 80 / 16 = 5, 64 / 16 = 4.
That "ad^3" bothers me; I'm not sure what you mean here.
I'm going to assume that you have (1/4*a*d^3)^2.
If that's the case, then you have (1/4)^2 * a^2 * d^6 = (1/16)*a^2*d^6.
If this is not what you were hoping for, double check to ensure that you have copied down this problem exactly as it was presented.
Answer:
angle ABC is 130 degrees
Step-by-step explanation:
This is the quickest and simplest way to gind the answer.
Angle CBD and angle ABC are linear pairs. Linear pairs are supplementary meaning angle CBD and angle ABC equal 180 degrees. Since angle CBD is 50 degrees and you know both angles need to add up to 180 degrees all you need to do is subtract 180 from 50 degrees.
