Determine whether the series converges: sum(k=1 -> infinity) [1/(1+lnk)]

1 answer:

3 0

Series is strictly decreasing so apply Integral test.
Limit test is also applicable, it implies it may converge.
Integrate 1/(1+lnx) you may need product rule.

True or false: two points with the same x-coordinate are always on the same vertical line

Vesna [10]

True, you can even test it out yourself. If the domain (x) is the same then it will be a vertical line. Like if you graphed (1,2) (1,4), (1,6) it will be a vertical line on your graph. I hope this helps!

A jar of 150 jelly beans contains 22 red jelly beans, 38 yellow, 20 green, 28 purple, 26 blue, and the rest are orange. Let B =

Oduvanchick [21]

Answer: $\frac{11}{75}$

Step-by-step explanation:

R is the event of getting a red jelly bean. 22 out of the 150 jelly beans are red. That means it is a $\frac{22}{150}$ chance of getting a red jelly bean.

Simplified that is $\frac{11}{75}$

Which of the division expressions below has a remainder? Select all that apply.

gavmur [86]

Answer:

A, B, C, & E

Step-by-step explanation:

A) 19,456 ÷ 6 = 3,242 $\frac{2}{3}$

(2/3 is 0.666666666 etc)

B) 28,765 ÷ 13 = 2,212.692308...

C) 4,145 ÷ 3 = 1,381 $\frac{2}{3}$

(2/3 is 0.666666666 etc)

D) 4,165 ÷ 17 = 245

(Not bolded because it is not an answer)

E) 44,312 ÷ 16 = 2,769.5

C -> When dividing by three, if the first number's values do not add up to a multiple of 3 there will be a remainder. Example from your problem,

4,145 -> 4 + 1 + 4 + 5 = 14 -> 14 is not a multiple of 3, so there is a reminder

D -> No decimal / fraction, no remainder!

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
