Answers
Answer:
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.
The center of the data for students has a value less than that of the center of the data for teachers.
Step-by-step explanation:
Based on the shape of the two dot plot correct statements are as follow
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.
What is number line?
" A number line is a representation of straight line on which numbers are marked at equal intervals."
According to the question,
As we can see in the diagram of number line dot,
The center of the data for students is near to 2 .
The center of the data for teachers is more than 3.
Therefore,
The center of the data for students has a value less than that of the center of the data for teachers.
From the diagram of number line dot plot we can observe this
The center of the data is to the right of the dot plot for both teachers and students.
Teachers variation is from 0 to 8 .
Students variation is from 0 to 4.
Therefore,
There is a greater variation in the data for teachers than for students.
No , teachers data is cluster around 3 and 4.
Number of teacher surveyed = 8
Number of students surveyed = 5
Hence, first three statements are correctly compare teachers and students.

How many Students are going?
How many Adults are going?
There are other schools from Holyoke going on the cruise too. If the cruise ship holds a maximum of 400 passengers and each school gets the same number of tickets, how many schools can come on the cruise?
Answers
Answer:
75 students are going. 15 adults are going.
Step-by-step explanation:
Since the question says there are 90 tickets in total, 75 student ticket plus 15 adult tickets equals 90 tickets in total. Also 75 divided by 15 is 5, which suits the ratio of 5 students to per adult.

Which of the following is another way to express the equation 13 = -3 + z?
A. 13 = - z - 3
B. 13 = z - 3
C. 13 = - z + 3
D. 13 = z + 3
Answers
The other representation of the given equation 13 = -3 + z will be 13 = z - 3 thus option (C) is correct.
What is the equation?More than one variable may be present inside a linear equation.
An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
As per the given equation,
13 = -3 + z
Since, A + B = B + A
Thus, -3 + z can be written as z - 3
So, 13 = z - 3
Hence "The other representation of the given equation 13 = -3 + z will be 13 = z - 3".

Which of these graphs is the solution set for the equation y = -3x - 2?
Answers
The negative before the 3 means the slope is going down
The 3 means it goes 3 down every time it goes right one, the number before the x is the slope and slope is rise over run, 3 = 3/1 so it would normally mean it goes up 3 every time it goes right one but because the 3 is negative it means the line goes down
The negative two at the end moves the line down two, if it were plus two the line would go up two, the number in this spot is what determines the vertical translation
Put it all together and you get the line has goes down 3 every time it goes right one and crosses the y axis at -2
