Answer:
$22
Step-by-step explanation:
First, you should add the two values, $130 and $24. When you do, you get $154. Then, divide $154 by 7, to see how much he needs to earn each week. Your answer should be $22.
9 gallons.
first find the average gallons spent on 10 plants which is 3 gal, then multiply 10 by 3 to get 30. 3x3=9
Note: The function is below the graph, so it is less than.
Answer:
a) 1/64
b) 1/4096
Step-by-step explanation:
As you can tell from the example, the exponent of 1/2 is the number of heads in a row.
a) p(6 heads in a row) = (1/2)^6 = 1/(2^6) = 1/64
b) p(12 heads in a row) = (1/2)^12 = 1/(2^12) = 1/4096

<em>Additional comment</em>
The probability of a head is 1/2 because we generally are concerned with a "fair coin." That is defined as a coin in which each of the 2 possible outcomes has the same probability, 1/2. Similarly, a "fair number cube" has 6 faces, and the probability of each is defined to be the same as any other, 1/6. Loaded dice and unfair coins do sometimes show up in probability problems.
