Answer:
Infinitely many solutions
Step-by-step explanation:
y+12=y+10+2
y+12=y+12
y=y
Thus, y can be any real number and there's infinitely many solutions.
-18.8 or abosolute value 18.8
Answer:
A) 56
B) 21
Step-by-step explanation:
A) The number of delegations possible is given by;
C(n,r) = n!/[(n - r)!(r!)]
In this question, n = 8 and r =3
Thus,
C(8,3) = 8!/[(8 - 3)!(3!)] = 56
B) Since a particular member must be in the delegation, the number of outcomes will now be;
C(n, r) - C(n-1,r)
Thus, we have;
C(8,3) - C(7,3)
= 56 - [7!/[(7 - 3)!(3!)]
= 56 - 35 = 21
Stratified random sampling is used to subdivided into groups by volume of sales.
According to the statements
Manufacturers are subdivided into groups by volume of sales. and for this Stratified random sampling is used.
Stratified random sampling is the technique used divide the population can be partitioned into subpopulations.
Thus, Stratified random sampling is used to subdivided into groups by volume of sales.

2 hours = 60*2 = 120 minutes
120/120 = 1
Margie handed out 1 flyer every minute
Jaxon handed 18/15 = 1.2 flyers per minute
so Jaxon is faster
