- 3.5
The rule of the pattern 50 40 45 35 is subtract 10 then add 5.
575
The given numbers of 15 and 35 are not prime numbers but they add up to 50
You could add all 50 test scores or use frequency. Add 35 times 80 percent to 15 times 70 percent and then divide by the 50 students.
Without a calculator...Half (or 50%) of 35 is 17.5.Half of half (or 50% of 50% which is 25%) of 35 is 8.75.So, if we add together 50% of 35 (which is 17.5) and 25% of 35 (which is 8.75) we will get 75% of 35 (which is 17.5 + 8.75 = 26.25)Therefore, 75% of 35 is 26.25.
70
35 out of 50 is 70% 50 out of 35 is 142.86%
35 out of 50 = 100*35/50 = 70%
15
50+50+(11-1-10)*(2+5+15+35)
It is: 50/35 = 10/7
