Answer:
x=26
y=9
Step-by-step explanation:
5x-17+3x-11=180
8x=180+17+11
8x=208
x=26
3(26)-11=78-11=67
2y+5=90-67
2y=90-67-5
2y=18
y=9
Answer:
\mu = 41.1091, 43.6109
Step-by-step explanation:
given data sets
40.2,43.1,45.5,44.5,39.5,40.2,41.0,41.6,43.1,44.9
sample mean = (sum of all value / number of value)
sample mean = 423.6/10 = 42.36
standard deviation = 2.158 given
t =1.833 for 90% confidence interval at df = n-1 = 9
90% confidence interval is given as
\mu = 41.1091, 43.6109
