Answer:

a = - \frac{1}{2}

Step-by-step explanation:

22 = a(0 - 10)² + 72

simplify:

22 = a(-10)² + 72

22 = a × 100 + 72

22 = 100a + 72

subtract 72 from both sides:

100a = -50

divide both sides by 100:

a = - \frac{1}{2}

There are 26 prize tickets in a bowl,labeled A to Z. What is the probability that a prize ticket with a vowel will be chosen,not
labwork [276]

Answer:

3.1%, dependent event

Step-by-step explanation:

We have that vowel are 5, it is from A, E, I, O, U therefore the probability of drawing a vowel is:

5/26

since there are a total of 26 options to choose from. Then, when selecting that, we are left with 25 options and 4 vowels, therefore the probability would be:

4/25

Therefore the final probability is:

5/26 * (4/25) = 0.031

In other words, selecting a vowel and then another (without replacement) the probability is 3.1%

The events are dependent, since the first event affects the second event, since the number of vowels and the number of total options are reduced.
