11. If you rolled a six-sided die 242 times, how many times would you expect an odd number to appear?

Mathematics

4 0

The numbers on a six sided die are 1, 2, 3, 4, 5, 6.

Odd numbers are numbers that cannot divide 2 completely. Thus, the odd numbers here are 1, 3 and 5

Probability is expressed as

Number of favourable outcomes/total number of possible outcomes

The total number of possible outcomes is 6

The number of favourable outcomes is 3

Thus, the probability of rolling an odd number is

3/6 = 1/2

Thus, if the die is rolled 242 times, then the number of times you would expect an odd number to appear is

1/2 * 242 = 121 times

A cyclist estimates that he will bike 80 miles this week. He actually bikes 75.5 miles. What is the percent error of the cyclist
maw [93]

Answer:

<em>The percent error of the cyclist's estimate is 5.63%</em>

Step-by-step explanation:

<u>Percentages</u>

The cyclist estimates he will bike 80 miles this week, but he really bikes 75.5 miles.

The error of his estimate in miles can be calculated as the difference between his estimate and the real outcome:

Error = 80 miles - 75.5 miles = 4.5 miles

To calculate the error as a percent, we divide that quantity by the original estimate and multiply by 100%:

Error% = 4.5 / 80 * 100 = 5.625%

Rounding to the nearest hundredth:

The percent error of the cyclist's estimate is 5.63%

Vladimir [108]

<u>Question </u>

Select the three equations that this diagram could represent.

<u>                                                                                                                                     </u>

<u>Answer</u>

<em>Well, we first have to find out what the diagram says.</em>

<em>So what the diagram says is that  18 + 18 + 18 = 54.</em>

<em>Given this information,  we have to figure what other answers = 54.</em>

<em>Therefore the answers are </em>

(A) 18 * 3 = 54.

(D) 54/18 = 3

(E) 54/3 =18
