Part a: No, the outcomes do not seem to be equally likely. There is more of a chance that it will land open end up or open end down then on its side.

part b: The probability for it ending open end up is 50/100. Same with open end down. For on its side, there is 25/100 probability.

part c: In 1000 tosses, I predict the cup will land 250 times on its side.

part d:If we tape a quarter to the bottom of the cup, it will most likely land up end up. This is because the quarter is weighting down the cup, causing it to land upwards.

HELP !!! Evaluate f(-2) for the function f(x) = 3x2 + 2x - 5
Phoenix [80]

Answer:

3

Step-by-step explanation:

So we have the function:

f(x)=3x^2+2x-5

To evaluate the value of f(-2), substitute -2 for x. Thus:

f(-2)=3(-2)^2+2(-2)-5

Square first:

f(-2)=3(4)+2(-2)-5

Multiply:

f(-2)=12-4-5

Now, subtract:

f(-2)=8-5=3

So:

f(-2)=3

And we're done!
