Answer:
Step-by-step explanation:
Given that
sample size n = 55: x bar = 654.16 and s = sample sd = 162.34
Std error = 162.34/sqrt 55 = 21.889
For 95% CI we can use t critical value as population std dev is not known.
df = 54
t critical = 2.004
Margin of error = 2.004 *21.889 = 43.866
Confidence interval lower bound = 654.16-43.866 =610.294
Upper bound = 654.16+43.866=698.026
Confidence interval rounded off at 95% = (610.29, 698.23)
Answer:
33%
Step-by-step explanation:
311-208=103 ponds lost
103/311=33%
X-18 = 2 (X-25)
x-18 = 2x - 50
-18 = x - 50
32 = x
check
32-18 = 14 = 2(32-25) = 2*7
32 is the answer
Answer:
C
Step-by-step explanation:
Since the vertex is 2,1, that's the only equation that works for it. The 2 has to be the opposite, so -2, and the 1 stays 1.
