Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week. Fourteen people answered that they generally sell five cars; nineteen generally sell six cars; twelve generally sell seven cars; nine generally sell eight cars; eleven generally sell nine cars. Calculate the following. (Round your answer to two decimal places.)

sample mean = x

x = cars

x = 6.75 cars

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 65

14 people generally sell 5 cars

19 generally sell 6 cars

12 generally sell 7 cars

9 generally sell 8 cars

11 generally sell 9 cars

We have to calculate the sample mean.

Formula:

Thus, the weighted sample mean is 6.75 cars.

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.
