HELP! Use the ratio test to determine whether the series is convergent or divergent.

Mathematics
1 answer:
inessss [21]3 years ago

Answer:

A

Step-by-step explanation:

aₙ = 5ⁿ/n!

aₙ₊₁/aₙ = [5ⁿ⁺¹/(n+1)!] / [5ⁿ/n!] = 5/(n + 1) tends to zero when n tends to infinity.

zero < 1

so the series is convergent.

2. 3/4(-4 + 4x) = -3 + 3x   3/4 times 4 is 3, so if you distribute 3/4 (-4 + 4x), you will get -3 + 3x. 

3. -0.113(-4x - 4) = 0.452x + 0.452   0.113 times 4 is 0.452, but you need to make sure to have the correct signs. Since the product is positive and -0.113 is negative, you would have to multiply it by a negative to get the product.

If you're having trouble with multiplying by fractions, just use repeated addition in your head. For example, for the first problem, instead of trying to tackle 3/4 times 4, think 3/4 + 3/4 + 3/4 + 3/4.

3/4 + 3/4 = 6/4
6/4 + 3/4 = 9/4
9/4 + 3/4 = 12/4
12/4 = 3

For the second problem, when multiplying by a decimal, just do what you'd normally do for multiplication. When you get to the end, count how many digits you had behind the decimal before, and put the decimal in the corresponding space for the answer.

0.113
x    4
0452

There are 3 digits behind the 0 in 0.113, so there should be 3 digits behind the decimal in the answer. So, the answer should be 0.452.

Hope this helps!

A test of hypothesis is conducted to determine whether annual income and education level are independent. It is determined that
kramer

Answer: We concluded that annual income and education level are not independent.

Step-by-step explanation:

For the given situation, the null and alternate hypothesis can be formulated as:

H_0: annual income and education level are independent.

H_a: annual income and education level are not independent.

Given,  the value of test statistic is 24.32 and the critical value of test statistics is 13.32.

i.e. the test statistic value is greater than the critical value, thus we have enough evidence to reject the null hypothesis.

Therefore, we reject null hypothesis .

So , we concluded that annual income and education level are not independent.
