Answer:
b
Step-by-step explanation:
since coefficient of x = 0
The first one would be (-5,5) and the second one is (5,5) or 1.
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:
2/5 = 3x
It takes 2/15 hours to do one task.
Answer:
-1/6
Step-by-step explanation:
flip the slope
becomes
now the slope is going down so it becomes negative
= -1/6
