Which of the following is the best interpretation of the data displayed in the line plot below?
A. Small dogs weigh more than housecats.
B. The weights of small dogs are more consistent than the weight of housecats.
C. The housecats' weights have a higher mean and are more consistently centered around their mean.
D. The small dogs' weights have a higher mean and are more consistently centered around their mean.
Answer: C. The housecats' weights have a higher mean and are more consistently centered around their mean.
Step-by-step explanation:
if we were being more technical then he would be correct because the house cats have a higher mean than the smaller dogs.
SD= 9.9
HC= 11
so the house cats have a higher mean than the smaller cats, in addition has a more consistent mean then smaller dogs due to the range of the lowest in the highest number.
Answer:
C. The housecats' weights have a higher mean and are more consistently centered around their mean.

Use a net of the square pyramid, if necessary, to find the surface area of the pyramid.
Answer:
27 units squared
Step-by-step explanation:
First, we find the surface area of one of the triangles.
(3*3*0.5)
4.5
Next, we find the surface area of all of the triangles.
(4.5*4)
18
The next step is to find the surface area of the square.
(3*3)
9
The last step is to add the surface areas of the square and triangles together.
(18+9)
27
The surface area of the entire shape is going to be 27 units squared.
Find the surface area of the figure below. (attached image)
