Answer:
1 / 5
Step-by-step explanation:
n ( S ) = 5 + 12 + 8 + 10 + 15
n ( S ) = 50
Let R be the event of getting red jellybean.
n ( R ) = 10
P ( R ) = n ( R ) / n ( S )
= 10 / 50
P ( R ) = 1 / 5
Answer:
f(x) = 3^x -3
Step-by-step explanation:
The horizontal asymptote of an unmodified exponential function is y=0. Here, the horizontal asymptote is y=-3, so your answer will be of the form ...
f(x) = [some growing exponential term] -3
Only the second selection has this form. It also matches the given graph at x=1.

Answer:
- adult: 325
- children's: 225
Step-by-step explanation:
It usually works well to let a variable represent the higher-value item in the mix. Here, we can let 'a' represent the number of adult tickets sold. Then the total revenue is ...
1.50a +1.00(550 -a) = 712.50
0.50a = 162.50 . . . . . . . . . . . . . subtract 550 and collect terms
a = 325
c = 550 -325 = 225
325 adult and 225 children's tickets were sold.
Let the legs of the triangle be a and b, and the hypotenuse c.
Your first instinct might tell you to use the Pythagorean theorem to go about solving this because

. This works, but it is slow.
The fastest way to solve this is to recognize that the right triangle is a special triangle where the ratio of the sides are 3:4:5. This means that if the legs are 9 and 12, then the hypotenuse is 15 because 3*3 is 9, 3*4 is 12, and 3*5 is 15.
