Answer:

50

Step-by-step explanation:

Adding up 20, 30, 40, 50, 60, 70, 80, we get 350.  There are 7 numbers in this set, so divide this 350 by 7.  We obtain the mean, 350/7 = 50 (Answer B)

Ksivusya [100]
Hello!

I don't exactly understand your question. If you mean to be asking whether or not 1002 is geater than 100, it is.

If you mean to be asking to add it: 102 + 900 + 100 = 1102

The number of students who passed on the math exam was three-fourths of the total number of students who failed.
Alexxandr [17]

Answer:

one quarter of the total number of students will be those who failed their exam.

Step-by-step explanation:

Three - fourths = those who passed the exam

one quarter will be those who failed their exam

From the total number of the students.

Let's make an example

40 students who take the exam.

3 over 4 students from the total number of 40 take the exam and the result is passed and it mean 30 students passed in the exam.

1 over 4 students take the exam and the result is failed and it mean 10 students failed in the exam.

4 minus 3 over 4 will get the answer 1 over 4.

Use 1 over 4 to multiple with the total number of the students and that how you will get the answer for those who failed in their exam.

Sienna, Rhys, and Micah are all reading the same book for school. Sienna has read 40% as far as Rhys has, and Rhys has read 40%
ruslelena [56]

Based on the fact that Sienna has read 60 pages, we can infer that Micha has read 375 pages of the book.

Sienna has read 40% of what Rhys has read and that corresponds to 60 pages. The number of pages read by Rhys is therefore:

<em>= Number of pages / Percentage read </em>

= 60 / 40%

= 150 pages

The 150 pages read by Rhys is 40% of what Micah has read. Micah has therefore read:

= 150 / 40%

= 375 pages

In conclusion, Micah has read 375 pages.
