Well I’m back with another question- So uh I’m grasping the concept of this subject still since it’s gotten a bit more advanced ,so please don’t judge haha
Ok but here’s the question I need help with!

When Mr. Watson purchased his house, the dining room measured 20 feet long and 16 feet wide. Before he moved in, Mr. Watson paid a company to increase the length of the dining room by 4 feet.

Part A:
How much greater is the area of the new dining room than the old dining room?

Part B:
In the original room, an 8x10 rug covered a fractional part of the floor. For the new dining room, Mr. Watson wants to buy a rug to cover that same fractional part of the floor.

What could be the length and width of the new rug?

If you help, I will mark brainliest! Thank you.

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?
