Sara runs a website that helps people learn programming. Every month, Sara receives a subscription fee of Dhs10 from each of the subscribers to her website. Last month, the website had 100 subscribers. This month, 30 new members joined the website, and 10 members canceled their subscription. How much money has she made those two months?

she made 2200 Dhs for those two months?

Step-by-step explanation:

Monthly subscription fee of Sara's website for each subscriber = Dhs 10

Last month, the website had 100 subscribers.

Last month Sara received subscription fee = 100 × 10

                                                                      = 1000 Dhs

This month, 30 new members joined the website, and 10 members canceled their subscription.

Total number of subscribers this month = (100 - 10)+30 = 120 subscriber

This month Sara received subscription fee = 120 × 10

                                                                       = 1200 Dhs

She made money those two months = 1000 + 1200

                                                             = 2200 Dhs

she made 2200 Dhs for those two months?

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
