Answer:
60/25 is greater than 60/132
Answer:
5.6 thousand
Step-by-step explanation:
To find the mean absolute deviation (MAD), first find the mean (or average).
μ = (41 + 38 + 36 + 57 + 43) / 5
μ = 43
Next, subtract the mean from each value and take the absolute value.
|41 − 43| = 2
|38 − 43| = 5
|36 − 43| = 7
|57 − 43| = 14
|43 − 43| = 0
Sum the results and divide by the number of animals.
MAD = (2 + 5 + 7 + 14 + 0) / 5
MAD = 5.6
The number of solutions of a quadratic equation
ax^2+bx+c=0
Depends on its discriminant
/Delta=b^2-4ac
If /Delta>0 there are two distinct solutions
If /Delta=0 there are two coincident solutions
If /Delta<0 there are no solutions.
We know that there are two real solutions (I assume you mean distinct solutions), so we know that the discriminant is positive:

If there are no solutions.
We know that there are two real solutions (I assume you mean distinct solutions), so we know that the discriminant is positive:
b^2-4ac=9+28t>0\iff t>-\dfrac[9][28]
Answer:
13:8:7
Step-by-step explanation:
84 - 24 = 60
60 oranges were either ripe or unripe.
18 more ripe oranges than unripe oranges.
x + 18 = ripe oranges
x = unripe oranges
x + 18 + x = 60
2x + 18 = 60
2x = 42
x = 21
21 are unripe oranges
21 + 18 = 39
39 oranges are ripe.
Ratio of the number of ripe oranges to the number of rotten oranges to the number of unripe oranges.
39:24:21
