Answer:
-1<x<1 and 1<x
Step-by-step explanation:
We are asked to determine the interval in which our function shown in the graph has positive values.
In order to do so, we have to see for what values of x on x axis, the graph is above x axis.
As we can see in the graph, when we move from x = -1 towards right, the graph is above x axis. And towards left of x=-1 , the graph is below x axis. Hence answer is
-1<x<1 and 1<x
Answer:

Answer:
4+0.08 +0.0016+0.000032+ ....
Step-by-step explanation:
a+ar+ar²+ar³+ar⁴+…
the geometric series converges if |r| < 1
The geometric series converges:
4+0.08 +0.0016+0.000032+ ....
0.08=4*0.02
0.0016=4*(0.02)²
0.000032=4*(0.02)³
r=0.02<1
Answer:
This means that there is a 95% probability that the confidence interval will contain the true population mean. Thus, P( [sample mean] - margin of error < μ < [sample mean] + margin of error) = 0.95.
