A survey of a group of seventh graders and a group of teachers at a local middle school asked how many siblings they each have. The dot plots below show the results. .
Students
A dot plot titled Students. A number line going from 0 to 9 labeled number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9.
.
Teachers
A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9.
.
Based on the shape of the two dot plots, which statements correctly compare them? Select three choices.
.
The center of the data for students has a value less than that of the center of the data for teachers.
.
The center of the data is to the right of the dot plot for both teachers and students.
.
There is a greater variation in the data for teachers than for students.
.
Both sets of data cluster around 2.
.
The same number of teachers as students were surveyed.

A: The center of the data for students has a value less than that of the center of the data for teachers

C: There is a greater variation in the data for teachers than for students

E: The same number of teachers as students were surveyes

Step-by-step explanation:

edg2021 (Other person is wrong)

The center of value for students is more the left which is smaller. For both they are clustered closer to the left side, NOT the right. The teachers have more variation taking up more of the number line. There is no cluster around 2 for the teachers. Both teachers and students have 20 people surveyed.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
