Law Incorporation [45]3 years ago

Answer: 21.5

Step-by-step explanation:

Rounding 15.89: Find the number in the tenth place  8  and look one place to the right for the rounding digit  9 . Round up if this number is greater than or equal to  5  and round down if it is less than  5 . = 15.9

Rounding 5.557: Find the number in the tenth place  5  and look one place to the right for the rounding digit  5 . Round up if this number is greater than or equal to  5  and round down if it is less than  5 .  = 5.6

Sum up 15.9+5.6 and get 21.5

What is the slope of these two equations?
Juli2301 [7.4K]

Answer:

8. 0

9. undefined

Step-by-step explanation:

8. 0

> because the y variable is the same for all x-values, this is a horizontal line. Horizontal lines have a slope of 0.

  > <em>Thinking of slope as rise over run: we will always rise 0, and run __ from any two points--0 divided by any number is always 0</em>

9. undefined

> because the x variable is always the same, no matter what y variable we graph, we will have the same outcome. So, this would look like a straight line, which have an undefined slope.

   > <em>If you think of a slope as rise / run; if you go from any two points, there will be a 0 in the denominator--which is undefined</em>

Judy just calculated the standard deviation for a project she is working on. The value for the standard deviation is a small num
Contact [7]

Answer: b) The data is spread close to the mean

Step-by-step explanation: Theoretically, when the standard deviation of a statistical data is large or high, it simply means that the values in such statistical data set are farther away from the mean, On the other hand when the standard deviation is small or low, it simply means that the values of such statistical data are close to the mean of those data on average.

Therefore Judy's low standard deviation for her project simply indicates that her statistical data set is spread close to the mean.

Snoopy the dog is on a 11-ft long chain that is attached to the corner of a garage (see the picture below). If the chain does no
seropon [69]
11*2 = 22 (calculating the diameter)

Using πD for the area:
π * 22 = 22π

Getting 3/4 of the area because the dog can not move past the corners of the garage;

22π * 3/4 = 16.5π

Getting the answer in feet^2:
16.5 * 3.14 = 51.84 feet^2

Hope this helps! :)
