Step-by-step explanation:
Because the number seven is higher than one Third.
Write it as a mixed fraction 7/5 = 1 2/5
X = (15 - 8y)/9
-5[(15 - 8y)/9] + 12y = -107
(-75/9) + (40/9) + 12y = -107
y = -8.59
x = [15 - 8(-8.59)]/9
x = 9.3
(x,y) = (9.3, -8.59)
Answer:
In repeated sampling, 95% of the intervals constructed would contain the population mean.
