For this problem, let x be the width and y be the length of the rectangle. We use these variable to make an equation from the perimeter.
Perimeter = 2*Length + 2*WIdth
Perimeter = 2y + 2x
70 = 2y + 2x
The area of a rectangle is equal to the product of x and y. Since we want the equation in terms of x only, let's find y in terms of x.
y = 35 - x
Hence, the formula for area is:
Area = xy
Area = x(35 -x)
Area = 35x - x²
It would seem the problem requires you compute the mean, median, and standard deviation of each of the data sets. This is nicely done using the statistics functions of your graphing calculator.
Data Set A (mean, median, standard deviation) = (29.7, 29.5, √12.71)
Data Set B (mean, median, standard deviation) = (27.95, 27, √6.1475)
1. False. Data Set B is skewed to the right.
2. TRUE. 27.95 is within 3 of 29.7.
3. False. √12.71 ≠ √6.1475
4. False. The mean of Data Set A is 29.7.
5. False. Data Set A has the higher standard deviation.
6. TRUE. 29.7 is close to 29.5.
The true statements are
• the 2nd one
• the 6th one
It looks like the question you are asking is how far will the cart travel after 56 complete revolutions.
To answer this you will use the distance it will travel in 1 revolution (2690.28 m) and multiply it by 56.
2690.28 x 56 = 15655.68 meters or about 15.66 km.
