Answer:

The experimental probability of rolling a 2 is \frac{1}{4}.

Step-by-step explanation:

Since you didn't give any statements, I'll make one myself.

P of rolling a 2 (experimental): \frac{15}{60} =\frac{1}{4}

The experimental probability of rolling a 2 is \frac{1}{4}.

Step-by-step explanation:

<u>Step 1: Define</u>

3t + 7 = 2 + 5t

<u>Step 2: Solve for </u><u><em>t</em></u>

  1. [Subtraction Property of Equality] Isolate <em>t</em> terms:                                        7 = 2 + 2t
  2. [Subtraction Property of Equality] Isolate <em>t</em> term:                                         5 = 2t
  3. [Division Property of Equality] Isolate <em>t</em>:                                                        5/2 = t
  4. Rewrite:                                                                                                             t = 5/2
