Answer:
1/5 probability
Step-by-step explanation:
1) The total number of jelly beans is 20. This will be your denominator.
2) There are 4 red jelly beans. This is your numerator.
3) Using the numerator and denominator we have, your fraction is 4/20.
4) That can be simplified into 1/5.

Answer:
( 
, 0) and (8, 
)
Step-by-step explanation:
Curve is concave downward when the second derivative is negative.
y' = 
, by the Fundamental Theorem of Calculus
y'' = 
, which has a denominator that is always positive. The numerator 
is negative when x > 0 and when x < 8. So that is when y'' is negative, and consequently when the curve y is concave down.
123.5%
= 123.5/100
= 1235/1000
= (1235/5) / (1000/5)
= 247/200
= 1 47/200
The final answer is 247/200 or 1 47/200~
11
(9, 18, 27, 36, 45, 54, 63, 72, 81, 90 and 99)
Those numbers divisible by 9 are the multiple of 9; thus need to know how many multiples of 9 there are between 1 and 100:
100 ÷ 9 = 11 r 1 ÷ last multiple of 9 is 11 × 9 (= 99)
→ There are 11 - 1 + 1 = 11 numbers between 1 and 100 which are divisible by 9.
(They are 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99.)
