<h3>Answer: D) 0.44</h3>

==========================================================

Explanation:

Add up all the frequencies that correspond to outcomes that are more than 3

So we'll add up the last three frequencies (since they correspond to outcomes of 4, 5 and 6 all of which are greater than 3) to get 20+30+38 = 88

We have 88 occurrences of rolling either a 4, a 5 or a 6. This is out of 200 rolls total.

The empirical (or experimental) probability of getting more than 3 on the die is 88/200 = 0.44

Answer:

  • f(4) = -12
  • f(-2) = -6
  • f(2) = -10
  • f(0) = -8
  • f(-3) = -5

Step-by-step explanation:

Put the value where the variable is and do the arithmetic.

Personally, I find it easier not to deal with so many minus signs. I would rewrite the function to ...

  f(x) = -(8 +x)

I find it easier to evaluate the series of argument values when they are in increasing order. This serves as a check, because we expect the function values to be in decreasing order.

f({-3, -2, 0, 2, 4}) = -(8 +{-3, -2, 0, 2, 4}) = -{5, 6, 8, 10, 12} = {-5, -6, -8, -10, -12}

  • f(4) = -12
  • f(-2) = -6
  • f(2) = -10
  • f(0) = -8
  • f(-3) = -5

_____

As always, for repetitive evaluation of the same function, a spreadsheet or graphing calculator is a handy tool.
