Ineed , this is due today and i'm having trouble.

you and your friends want to go to a skate park on saturday. there are two amazing parks in your ‛s skate park, and brad‛s skate park. the parks both charge for skating. each park's price is described below. sam‛s skate park: $3 to get into the park and $1 for every hour of skating. brad‛s skate park: $5 to get into the park and $0.50 for every hour of skating. sam‛s skate park equation: brad‛s skate park equation: click here to graph your system. answer the following questions after graphing your equations:
1. what are your two equations for this system?
2. what does the x and y represent in your equations?
3. where do the two lines intersect?
4. what does this intersection mean?
5. which skate park has the best deal if you plan on skating for 3 hours? explain why you chose this park.

1. what is the phythaforean theorem? 2.what do we use it for? 1.what is the distance formula ? 2.what do we use it for?

The diagonals of a quadrilaretral intersect at (-1,4). one of the sides of the quadrilateral is bounded by (2,7) and (-3,5) determine the coordinates of the other side in order for the quadrilaretral to be a square.

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
