MATHEMATICS HIGH SCHOOL

PLEASE PLEASE HELP IM BEING TIMED The two-way table represents data from a survey asking students whether they plan to attend college, travel, or both after high school. A 4-column table with 3 rows. The first column has no label with entries travel, not travel, total. The second column is labeled college with entries 43, 24, 67. The third column is labeled not college with entries 10, 5, 15. The fourth column is labeled total with entries 53, 29, 82. Which is the marginal relative frequency for students who plan to attend college? Round the answer to the nearest percent. 18% 22% 35% 82%

Answers

Answer 1
Answer:

Answer: 82%

Step-by-step explanation:

- - - - - - - - college - - not college - - - - total

Travel - - - - 43 - - - - - - - 10 - - - - - - - - 53

Not travel - 24 - - - - - - - 5 - - - - - - - - - 29

Total - - - - 67 - - - - - - - 15 - - - - - - - - - 82

Marginal relative frequency of students who plan to attend college:

(Number of students who plan to attend the college / Total number of the students)

Number of students who plan to attend college = 67

total number of students = 82

Marginal relative frequency = 67/82

= 0.8170731

= (0.8170731) * 100%

= 81.7% = 82%

How does the speed change on the Graph? And what does a steeper line mean?

Answers

The steeper the line is (the larger the slope), the faster the speed is.  This is due to the fact that speed=distance/time and the slope=y/x which is distance over time on a distance v time graph.

Jim likes to day-trade on the internet. On a good day, he averages a $1100 gain. On a bad day, he averages a $900 loss. Suppose that he has good days 25% of the time, bad days 35% of he time, and the rest of the time he breaks even

Answers

Answer:

Jim will incur a loss of $2,400 in the 60-day period under review

Step-by-step explanation:

The question is incomplete. However, one assumption was made in attempting the question, ie, the timeframe was set at 60-days:

Jim likes to day-trade on the internet. On a good day, he averages a $1100 gain. On a bad day, he averages a $900 loss. Suppose that he has good days 25% of the time, bad days 35% of he time, and the rest of the time he breaks even, *what is Jim's balance after a 60-day period* ?

Solution

From the question, given period X = 60 days, and;

Jim's streak is as follows: 0.25X Profit : 0.35X Loss : (100 - (0.25+0.35) Even

Jim's streak = 0.25*60 : 0.35*60 : 0.4*60 = 15 + 21 + 24 (days)

15 profitable days = 15 * $1100 = $16,500

21 bad days 21*$900 = $18,900

24 even days = 24*$0 = $0

Balance after 60 days = $16500+(-$18900)+$0 = $16500-$18900 = -$2400

Final answer:

The expected daily value for Jim's day-trading hobby is -$40, meaning he should expect to lose $40 per day. Over three weeks of trading every weekday, this amounts to a total expected loss of -$600.

Explanation:

The subject of this question is expected value, a concept in probability and statistics, which essentially means the average result of a large number of trials in an experiment. In Jim's case, three possible outcomes are concerning his day-trading hobby: a good day ($1100 gain), a bad day ($900 loss), and a break-even day ($0 gain or loss).

Here's how we calculate:

  • A good day: 25% * $1100 = $275
  • A bad day: -35% * $900 = -$315
  • A break-even day: 40% * $0 = $0

The expected value of one day of trading for Jim is thus: $275 - $315 + $0 = -$40.

If Jim trades every weekday for three weeks (that is, 15 days), we can multiply the daily expected value by 15. So, Jim should expect to lose $40 * 15 = -$600 over three weeks.

The relationship between the number of hours and the number of miles Sam has driven is proportional. (1, 30) is a point on this graph, where x is the number of hours and y is the number of miles. What is true about this situation?

Answers

Relationship between the number of hours and the number of miles Sam has driven is proportional.

x = 1 number of hours
y = 30 number of miles

This means that for every hour Sam travels, he travels an additional distance of 30 miles.

Separate 185 into two parts so that one part is 31 more than the other part. Find each part.

Answers

Answer:

  108, 77

Step-by-step explanation:

Let x represent the larger part. Then ...

  x + (x -31) = 185

  2x = 216

  x = 108

  x -31 = 77

The two parts are 108 and 77.
