Answer:
It will be biased.
Step-by-step explanation:
By surveying only grades 1, 2, and 3, she is not taking a representation of the entire school. It is possible that the popular color or the color the students like would change over time and the opinion of the younger kids could be different from that of the older kids. Therefore, the sample is biased unless she surveys students from all grades.

Describe how a newspaper is organized. Why do you think the stories, pictures, advertisements, and cartoons are laid out the way they are?
Answer in paragraph form using 5-7 complete sentences.
Answer:
A newspaper is organized in a logical format. The front page has the most exciting news of the day. The editors determine what is most newsworthy for their readership. The A-section contains world and national news; the B-section contains local news. Some of the categories include entertainment, local news, national news, classified advertisement, and neighborhood news. They are laid out the way they are because they want to catch the reader's eyes. They want the reader to look at the newspaper and think "oh that looks interesting."
Which values of a, b, and c correctly complete the division?
1/4 divided by 5/6 = 1/a times b/c
a = 4, b = 5, c = 6
a = 1, b = 6, c = 5
a = 1, b = 5, c = 6
a = 4, b = 6, c = 5

The graph below shows the cost of pens based on the number of pens in a pack. What would be the cost of one pen?
Answer:
1.5 dollars
Step-by-step explanation:
Answer:
Step-by-step explanation:
We notice that every time one the number increases, it increases by 3. To find it, first we subtract 4.5 and 3 to get 1.5 and this point is going to be (2, 1.5) Now, to find the cost of 1, we have to subtract 3 again to get (1, -1.5)
The cost of one pen is -1.5

Step-by-step explanation:
An expression is a combination of numbers, variables, functions such as addition, subtraction, multiplication or division, etc.
The expression that shows the combined volume of the three boxes is 3.5x.
Option C is the correct answer.
What is an expression?An expression is a combination of numbers, variables, functions such as addition, subtraction, multiplication or division, etc.
We have,
Three box sizes:
Small, Medium, and Large.
The volume of the medium box is x.
The volume of the medium box = x ____(1)
The small box has half the volume of the medium box.
The volume of the small box = x/2 _______(2)
The large box has twice the volume of the medium box.
The volume of the large box = 2x _____(3)
Combining (1), (2), and (3) we get,
= x + x/2 + 2x
= (2x + x + 4x) / 2
= (7/2)x
= 3.5x
Thus the expression that shows the combined volume of the three boxes is 3.5x.

What is the equation in slope-intercept form of the line that passes through the point (5,0) and is parallel to the line represented by y = 1.2x + 3.8?
Answer:
y=1.2x-6
Step-by-step explanation:
place in the points
0=1.2(5)+b
distrubutive property
0=6+b
subtract 6 on both sides
-6=b
y=1.2x-6
The equation in the slope-intercept form of the line that passes through the point (5,0) and is parallel to the given line is y=1.2x-6.
The given equation is y = 1.2x + 3.8.
We need to find what is the equation in the slope-intercept form of the line that passes through the point (5,0).
What is the slope-intercept form?The slope-intercept form of a straight line is used to find the equation of a line. For the slope-intercept formula, we have to know the slope of the line and the intercept cut by the line with the y-axis. Let us consider a straight line of slope 'm' and y-intercept 'b'. The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as y= mx+b.
Now, the line of the equation that is parallel to y = 1.2x + 3.8.
Here, m1=1.2
The slopes of parallel lines are equal and the formula for the slope of parallel lines is m1 = m2.
Then, m2=1.2
Now, put m=1.2 and the point (5,0) in y=mx+b
That is, 0=1.2×5+b
⇒b=-6
The equation of the line is y=1.2x-6
Therefore, the equation in the slope-intercept form of the line that passes through the point (5,0) and is parallel to the given line is y=1.2x-6.

An equilateral triangle has three equal sides.
Write a relation for the perimeter of an equilateral triangle with side length k.
What is the perimeter of an equilateral triangle with side length 15 cm?
Answer:
Step 1. Perimeter P means adding up all three sides of a triangle.
Step 2. Then P=s+s+s=3s where s is the length of the side of the equilateral triangle.
Step 3. ANSWER: Perimeter P=3s.
I hope the above steps and explanation were helpful.
Step-by-step explanation:
HOPE THIS HELPS
Answer:
p = 3k
45cm
Step-by-step explanation:
Since all sides of an equilateral triangle are equal, to find perimeter, you multiply the number of sides by the length of one side.
So the equation would be p = 3k (k represents the side length and 3 is the number of sides)
If a equilateral triangle has a side length of 15, you just multiply 15 by the number of sides.
3 (15cm) = 45cm

Step-by-step explanation:
180-(90+33)=57
90-57=33
180-(120+33)=27
Answer:
? = 27
Step-by-step explanation:
Keep in mind that all angles in a triangle equal 180
Add up all the known angles in triangle 1
90 + 33 = 123
and subtract it by 180 to find the third angle
180 - 123 = 57
then subtract 57 by 90 to find the other side of 90 degree angle the to triangles share
90 - 57 = 33
next add the angle we just found by 120
120 + 33 = 153
finally subtract 180 by 153
180 - 153 = 27

Use a graph to find x and y values that make both y=-23x+3 and y=2x−5 true.
Answer:
y=x^2
Step-by-step explanation:
The graph of the equation y = - 23x + 3 and y = 2x - 5 is attached in the image below.
What is the graphical solution of a system of equations?Graphical solutions of a system of equations are a way of finding the intersection points of all the equations given.
A system with two or more than two equations has a solution only when they have a common intersection point.
Given, Are two equations y = - 23x + 3 and y = 2x - 5.
Subtracting equation 1 from equation 2 we have,
25x = - 8.
x = - 8/25.
y = - 2(8/25) - 5.
y = - 16/25 - 5.
y = (- 16 - 125)/25.
y = - 141/25.

Answer:
First week: 1.34 Original Cost: 3.35
Step-by-step explanation:
So you know how much the second week cost $1.34. So to find the first week you need to divide 40% with 100 to get .4, after getting .4 you need to get the second weeks cost and divide 1.34 to .4 and you get 3.35. That is your original cost. So when you divide 3.35 with .4 for the first discount of the first week you get 1.34
