(3^x-2)/9^x=1/3^x-2/9^x
which converges by thereom
it converges to 10/72=5/36

Answer:

a.1.90 years

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.99}{2} = 0.005$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.005 = 0.995$ , so $z = 2.575$

Now, find the margin of error M as such

$M = z*\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

In this question:

$n = 25, \sigma = 3.8$

$M = 2.575*\frac{3.8}{\sqrt{25}} = 1.90$

So the correct answer is:

a.1.90 years

Proving Angles Congruent: Find the value of x. (5x+15) degrees = (6x-10) degrees

Andrew [12]

Answer:

25 = x

Step-by-step explanation:

If the angles are congruent, they are equal

5x+15 = 6x-10

Subtract 5x from each side

5x+15 -5x = 6x-5x-10

15 = x-10

Add 10 to each side

15+10 = x-10+10

25 = x

Select 2 strategies that we can use to add 115+497

Gemiola [76]

Answer:

B. Add 115+500 then subtract 3

C. Add 112+500

Step-by-step explanation:

Any strategy that gives a sum of 612 will work. Strategy A gives a sum of 602, so is not useful.

The appropriate choices are B and C.

B: 115 +497 = 115 +(500 -3) = (115 +500) -3

C: 115 +497 = 115 +497 -3 +3 = (115 -3) +(497 +3) = 112 +500
