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:
probability of tossing a coin 3 times and getting heads each time is 1/8
Step-by-step explanation:
A coin has 2 sides (heads and tails) therefore you have a 50% chance of getting either heads or tails for each toss. Therefore, the probability of getting heads for 1 toss is 1/2. Now, tossing it 3 times and getting heads each time essentially means you would have to do (1/2)×(1/2)×(1/2) which would give you 1/8 as the probability of tossing a coin 3 times and getting heads each time.
Answer:
Step-by-step explanation:
first of all, simplify your fraction. f(x)= -2(x+3) + 4
f(x)= (-2x-6) + 4
f(x)= -2x-2
y intercept is -2 and the slope is -2, go down 2 and right 1
Answer:
A & B
Step-by-step explanation:
A) V = pi×r²×h
= 3.142 × 8² × 5 = 1005.44 cm³
B) V = ⅓ × 18×16 × 12 = 1152 cm³
C) V = ½×5×3 × 7 = 52.5 cm³
Answer:
-2.5 = x
Step-by-step explanation:
Multiply by what's in the parentheses by 2.
6x - 1 = 4x - 6
Add 6 to both sides of equation.
6x + 5 = 4x
Subtract 6x from both sides.
5 = -2x
Divide both sides by -2.
-2.5 = x
