Answer:
Kindly check explanation
Step-by-step explanation:
Given :
Relative frequency = frequency / total frequency
Total frequency = 389+335+975+351+72 = 2122
Response ________ Frequency __ R/ frequency
Never ____________ 389 _ 389/2122 = 0.180
Rarely ____________ 335 _ 335/2122 = 0.158
Sometimes _________975 _975/2122 = 0.459
Most of the time _____ 351 _ 351/2122 = 0.165
Always ____________ 72 __ 72/2122 = 0.034
Answer: $960
Step-by-step explanation:
10*6= 60
60*16= 960
from second equation y = 18-x so:-
x(18 - x) = 30
x^2 - 18x + 30 = 0
x = 16.14, 1.86
when x = 16.14 y = 18-16.14 = 1.86
when x = 1.86, y = 16.14
so one variable = 16.14 and the other = 1.86 Answer
