Answer:
Below.
Step-by-step explanation:
To find the number of students in each grade you multiply the marks by the frequency density. The number of students is given by the area under the rectangles.
So to find the number of students with grade U (< 160) it is:
120 * 0.2 + 40*0.5
= 24 + 20
= 44.
The number for Grade E
= (200 - 160) * 0.5
= 40 * 0.5
= 20.
The others can be found in the same way.
Answer:
equation is y-11 =4
so the number is 15. thats all
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
A common factor is a number such that both 17 and 25 are divisible by that number. In this case, the greatest common factor of 17 and 25 is 1.
Answer:
12x5 or 16x(3+2)
Step-by-step explanation:
You can factor out 16 and get 16x(3+2). Both are factors of 48+32 because 3+2 is 5 and if you do 32+48 you get 60 which can be factored by 5. Or you can add them first to get 60 and then factor out 12 to get 12x5. Hope this helps!
2 dozen = 2 3/8
1 dozen= 1 3/16
5 dozen= 5 15/16
Hope this helps
