Answer:
13.4
Step-by-step explanation:
Divide the number of meters in a mile (1,609.344) by the number of seconds in an hour (3,600): 1,609.344 divided by 3,600 equals 0.44704. One mile per hour equals 0.44704 meters per second.

Victor wants to see if positively greeting children as they enter the classroom reduces problem behaviors. He randomly assigns 10 second- and third-grade classrooms to one of two conditions: classes where the teacher greets each student by name and with a smile as they enter the classroom and classes where the teacher does not greet students. During a 4-week period, he asks teachers to track the number of problem behaviors per classroom on a daily basis via a strict protocol he has designed. What is the control group
The control group in the experiment are the classes where the teacher does not greet the students
A control group in an experiment is made up of groups of people that do not receive the experimental treatment.
The purpose of a control group is to allow the researcher study one variable at a time.
Victor is conducting an experiment on if positively greeting children as they enter the classroom reduces problem behaviours.
The experimental treatment here is positively greeting the students.
The group that do not receive this experimental treatment are referred to as the control group.
At the end of the experiment, Victor would compare the behaviours of the students in the control group with the behaviour of those who were part of the experimental group to see if greeting reduced problem behaviours.

After 1 hour, Yao had completed 25% (1/4) of the 2-hour Mathematics paper.
In order to understand the fraction of time Yao had spent on the Mathematics paper after 1 hour, let's break down the problem. Yao was given a 2-hour Mathematics paper to complete, and he answered 5 questions in the first hour.
Now, let's calculate the fraction of time that had passed. To do this, we can set up a ratio of the time Yao had spent to the total time available. The time Yao spent is 1 hour, and the total time available is 2 hours. So the fraction of time that had gone can be represented as:
= Time spent / Total time
= 1 hour / 2 hours
= 1/2
Therefore, after 1 hour, Yao had completed half of the allotted time. However, we are asked to express this fraction in terms of questions answered. Yao had answered 5 questions out of a total of 20 questions.
To express the fraction of time in terms of questions answered, we can set up another ratio. The questions Yao answered is 5, and the total number of questions is 20. So the fraction of time that had gone can be represented as:
= Questions answered / Total questions
= 5 questions / 20 questions
= 1/4
Hence, after 1 hour, Yao had completed 1/4 of the total questions in the Mathematics paper. This means he still had 3/4 (or 75%) of the questions to complete in the remaining hour.

Use coordinate notation to enter the rule that maps each preimage to its image. Then identify the transformation and confirm that it preserves length and angle measure.
S (−3, 4) arrowright S′ (−2, 2)
T (3, 4) arrowright T′ (4, 2)
U (−1, 0) arrowright U′ (0, −2)
The transformation is a
(select)
given by the rule: (x, y)= ____
Since ST =
(select)
, SU =
(select)
, and TU =
(select)
, the transformation preserves length.
Since mangleS =
(select)
, mangleT =
(select)
, and mangleU =
(select)
, the transformation preserves angle measure.
In geometry, transformations are used to move points from one position to another.
The transformation is a rigid transformation given by [tex](x,y) \to (x + 1, y-2)[/tex]. It preserves lengths and anglesThe preimage is given as:
[tex]S =(-3,4)[/tex]
[tex]T = (3,4)[/tex]
[tex]U = (-1,0)[/tex]
The image is given as:
[tex]S' = (-2,2)[/tex]
[tex]T' =(4,2)[/tex]
[tex]U' = (0,-2)[/tex]
Using points S and S' as our reference point, we have:
[tex]S =(-3,4)[/tex] and [tex]S' = (-2,2)[/tex]
Calculate transformation
[tex](x,y) \to S -S'[/tex]
[tex](x,y) \to (-2,2)-(-3,4)[/tex]
Rewrite as:
[tex](x,y) \to (-2--3,2-4)[/tex]
[tex](x,y) \to (-2+3,2-4)[/tex]
[tex](x,y) \to (1,-2)[/tex]
So, the transformation from the preimage to image is:
[tex](x,y) \to (x + 1, y-2)[/tex]
Calculate the lengths of the sides of the preimage and the image
Using the following distance formula, we have:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
So, we have:
[tex]ST = \sqrt{(-3 - 3)^2 + (4 - 4)^2} = 6[/tex]
[tex]SU = \sqrt{(-3 - -1)^2 + (4 - 0)^2} = \sqrt{20[/tex]
[tex]TU = \sqrt{(3 - -1)^2 + (4 - 0)^2} = \sqrt{32[/tex]
and
[tex]S'T' = \sqrt{(-2 - 4)^2 + (2 - 2)^2} = 6[/tex]
[tex]S'U' = \sqrt{(-2 - 0)^2 + (2 -- 2)^2} = \sqrt{20[/tex]
[tex]T'U' = \sqrt{(4 -0)^2 + (2 -- 2)^2} = \sqrt{32[/tex]
Since
[tex]ST = S'T'= 6[/tex]
[tex]SU = S'U'= \sqrt{20[/tex]
and
[tex]TU = T'U'= \sqrt{32[/tex]
Then, the transformation preserves length
From the graph of [tex]\triangle STU[/tex] and [tex]\triangle S'T'U'[/tex]
Since
[tex]\angle S = \angle S' = 76^o[/tex]
[tex]\angle T = \angle T' = 45^o[/tex]
[tex]\angle U = \angle U' = 59^o[/tex]
Then, the transformation preserves angle measure.

x and y intercept of y= -2x - 4
Answer:
y - intercept is (0,-4)
x intercept is (-2,0)
Step-by-step explanation:
y - intercept is b from y = mx + b
in this case it is -4
y intercept is (0,-4)
x intercept can be found by replacing y with 0
0 = -2x - 4
4 = -2x
x = -2
x intercept is (-2,0)

Jane is solving the equasion -2x + 4 = 18. She tells her partner that they should add two to both sides first since that is the inverse of -2. Did Jane start this equation correctly? Explain your reasoning
Answer:
No
Step-by-step explanation:
Given
- 2x + 4 = 18
note the inverse of - 2 is - [tex]\frac{1}{2}[/tex] not - 2
However , the first step is to isolate the term in x by subtracting 4 from both sides.
- 2x = 18 - 4 = 14 ( divide both sides by - 2 )
x = - 7
