Step-by-step explanation:
Given:
x = 26214.47
s = 5969.25
n = 15
t = 2.046
The confidence interval is:
CI = x ± t (s / √n)
CI = 26214.47 ± 2.046 (5969.25 / √15)
CI = (23061.06, 29367.88)
Answer:
One solution
Step-by-step explanation:
0.75 (x + 40) = 0.35 (x + 20) + 0.35 (x + 20)
0.75x + 30 = 0.35x + 7 + 0.35x + 7
0.75x + 30 = 0.7x + 14
0.05x + 30 = 14
0.05x = -16
x = -320
Hope this helps!
Answer:
YES BUT BARELUY
Step-by-step explanation:
Answer:
I think 64%
Step-by-step explanation:
6+9+10 = 25

6x4 = 24
10x4 = 40
24+40 = 64
64/100 = 64%
Sry if this is wrong but I think this should be correct
