Answer:
A
Step-by-step explanation:
We would need to multiply the number of trials (which is 500) by the probability of choosing a red in 1 try from the information given.
<em>There are 50 in total, and 8 of them are red, so:</em>
P(red) =
<em>Now we multiply this with 500 to get:</em>
The correct answer is A.

The table is an exponential function, and the equation that represents this function is
The table is given as:
x F(x)
4 15
5 31
7 127
8 255
Rewrite the table as:
x F(x)
4 16 - 1
5 32 - 1
7 128 - 1
8 256 - 1
Express as a base of 2
x F(x)
4 2⁴ - 1
5 2⁵- 1
7 2⁷ - 1
8 2⁸ - 1
Notice that the function is 1 subtracted from 2 raised to the power of the input.
This is represented as:
Hence, the equation of the table is
