The answer for x is 9. Hope this helps. See work below.
Answer:
1 Choosing Appropriate Measures
The dot plot shows the average number of hours students in a class
sleep each night.
6 7 8 9 10
Time (hours)
Amount of Sleep
a. What are the most appropriate measures to describe the center
and the variation?
Most of the data values are on the right clustered around 9, and the
tail extends to the left. The distribution is skewed left.
So, the median and the interquartile range are the most
appropriate measures to describe the center and the variation.
b. Describe the center and the variation of the data set.
The median is 8.5 hours. The fi rst quartile is 7.5, and the third
quartile is 9. So, the interquartile range is 9 − 7.5 = 1.5 hours.
The data are centered around 8.5 hours. The middle half of the
data varies by no more than 1.5 hours.
Answer:
UST =40.4, RST=80.8
Step-by-step explanation:
Bisects means divides in two, therefore UST is the same as RSU (40.4) all you need to do to solve for RST is multiply 40.4 by 2 which is 80.8
Answer:
C
Step-by-step explanation:
I'm super sorry if I get this wrong you don't have to choose C I feel like I'm wrong but have a nice day
Precision is more like consistency. Take a rifle range for example. Sure, all the shots may be off centered, but if they're tightly grouped together, it shows that the shooter had precision in their shooting. Accuracy is how close to spot on the attempts or shots generally are. They would end up more towards the center, but a little more spread out.
