Suppose an and bn are series with positive terms and bn is known to be convergent. (a) If an > bn for all n, what can you say about an ? Why? an converges by the Comparison Test. an converges if and only if an ≤ 2bn. We cannot say anything about an . an converges if and only if an ≤ 4bn. an diverges by the Comparison Test. (b) If an < bn for all n, what can you say about an ? Why? an converges if and only if bn 4 ≤ an ≤ bn. an converges if and only if bn 2 ≤ an ≤ bn. an converges by the Comparison Test. an diverges by the Comparison Test. We cannot say anything about an .

the answer will be the last one

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
