-12 both sides then you get 3x = -30 divide by 3 which equals x = 10 or -10
Answer:
Option b.
Step-by-step explanation:
Sample size n = 9
sample mean = 217.222
Standard deviation s = 1.202
alpha a = 0.025
H0 : u = 216
H1 : u > 216 ( claim)
Now run a T test and result is :
Test statistic, t =
t =
=
t = 3.0509
Critical value = t(a,n-1) = t(0.025,9-1)
= 2.306
Since t > critical value, Hence reject H0.
Option b. is the answer. Yes, because computed t is greater than the critical value.
Answer:
B = C + (C - A) = (51/50 + 51/50 - 2, 457/50 + 457/50 - 9) = (1/25, 232/25).

Answer:
hannah is 47 and Anthony is 45
Step-by-step explanation:
Sum= 92= a+(a+1)
sum= 45+(46+1)
sum= 45+47
