If u find the answer put square 2 bc its had 4 sides
Answer:
X = 12 Y = -29
Step-by-step explanation:
X+Y= -17
X-Y=41
Solve for y in first equation
Y=-17-x plug y into the 2nd equation
X-(-17-x)=41
X+17+x=41
2x=41-17
2x=24
X=12
Y=-17-(x)
Y=-17-12
Y=-29
X+Y=-17
12+-29=-17
X-Y=41
12- -29=41

Answer:
(11.242 ; 12.958)
Step-by-step explanation:
The confidence interval is obtained using the relation :
C. I = xbar ± Zcritical * s/√n
Given that ::
xbar = 12.1 ;
Standard deviation, s = 16.6
n = 1012
C. I = 12.1 ± 1.645 * (16.6/√1012)
C.I = 12.1 ± 0.8583881
C. I = 11.242 ; 12.958
