Answer:
The conclusion that both groups of overweight and non - overweight got cardiovascular benefit from playing DDR games requires Inferential statistics.
Step-by-step explanation:
Inferential statistics is simply a type of research statistic whereby a generalized conclusion is made about a larger group based on representative observations
Now,in the given question, we see that both group hearts were above the minimum recommended for cardiovascular exercise. Now we can infer that the DDR games played by both groups gave them cardiovascular benefits. This conclusion is an example of Inferential statistics where we generalize about a large population based on observations from a small sample.
Thus the conclusion that both groups of overweight and non-overweight got cardiovascular benefit from playing DDR games requires Inferential statistics.
Answer:
The answer is the first one and the last one.
Step-by-step explanation:
If an account cost $1 and each song is 1.5x. It has to be less than or equal to 25. So it would be $1 for (the account plus) 1.5x for (how many songs he buys) is less than or equal to 25 (the ammount on the gift card).
Answer:

Step-by-step explanation:
step 1
Find the area of complete circle
The area of the circle is given by the formula

we have

substitute


step 2
Find the area of the shaded region
we know that
The area of complete circle subtends a central angle of 360 degrees
so
using proportion
Find out the area of the shaded region if the central angle is equal to 80 degrees
