Consider the dot plot which shows the distribution of data collected on the amount of time Jason sleeps each night. Find the dif

Tatiana [17]

Answer:

A) 0.2

Step-by-step explanation:

From least to greatest, the data points are

6, 6, 6, 7, 7, 7, 8, 8, 8, 9

To find the mean, we find the sum of the data points and divide by the number of data points, 10. The sum of the data points is

6+6+6+7+7+7+8+8+8+9 = 72

Dividing by 10, the mean is 72/10 = 7.2.

The median is the middle number in the set. This is 7.

The difference between the mean and the median is

7.2-7 = 0.2.

Mark wrote the highest score he made on his new video game as the product 70×6,000. Use the Associative and Commutative Properti

saveliy_v [14]

The <em>correct answer</em> is:

We can use the associative property to write 70 as 7*10. We can do this same process to write 6000 as 6*1000. This gives us:

(7*10)*(6*1000)

Using the commutative property, we can rearrange the factors of this problem

(7*6)*(10*1000)

7*6 is in our multiplication tables, and we know that powers of 10 allow us to just add the correct number of zeros. This means we would have 7*6=42, and have 4 zeros, for 420000.
