Answer:
A. 10/19
Step-by-step explanation:
The mean is 7.63, so 8,9, and 10 are above that. There are 9 that are either 8, 9, or 10. 19-9=10, therefore making the only possible answer 10/19
I hope this helps you :)
That equals 186 and if you wanted a fraction you can add on 27/38 so when you take 38•186=7068 then you take 7095-7068=27 then that's your answer 186 27/38 and if you didn't want the fraction it would be 186r27
Answer:
25
Step-by-step explanation:
The angle at C is 90 degrees, and BCD is a right triangle, so we can applythe Pythagorean theorem here -- 60²+m²=65², so 65²-60²=m²=625. The possible values for m are 25 and -25, and since m can't be negative, 25 is our answer as 25 is the square root of 625
D. 3 to 5
This is because if you simplify the ratio by dividing each number in the ratio by 4, therefore for every group of 5 birds 3 of them are parrots
