Answer:
y > -1/6 x+1
Step-by-step explanation:
The graph line is dotted. Dotted lines means greater than or less than. ( <, >)
Solid lines means less than or equal to or greater than or equal to (≤,≥)
Since the graph is shaded above the line, that means y is greater than the line. If it were shaded below the line, y would be less than.
y > -1/6 x+1
Answer:
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where n=sample size
= sample mean
=sample standard deviation
= critical t-value (for two tailed )
Let be the confidence interval for the population mean mercury concentration.
As per given , we have
Sample size : n= 28
degree of freedom = 27 [df=n-1]
Sample mean : cc/cubic meter
Sample standard deviation : s= 0.0036
Significance level :
Critical two-tailed test value :
(Using t-distribution table.)
We assume the population is approximately normal.
Now, the 98% confidence interval for the population mean mercury concentration will be :-
Required confidence interval :
Answer:
x = 27
Step-by-step explanation:
(whole secant) * (external part) = (tangent)^2
(x+48)* 48 = 60^2
(x+48)* 48 = 3600
Divide each side by 48
x+48 =75
Subtract 48 from each side
x = 75-48
x=27
X=2
Explanation:
You need to find the midpoint of the segment
-2+6=4
4/2=2
The coordinate of the hive is the point of interaction of the two lines.
We have the two equations:
