Answer:
A model with 12 squares labeled exact value and 3 squares labeled error.
Step-by-step explanation:
The proportion of error is the number of errors divided by the number of trials. The percentage is the proportion multiplied by 100.
A model with 12 squares labeled exact value and 3 squares labeled error.
3/12 = 0.25
0.25*100 = 25%
This is the answer.
A model with 10 squares labeled exact value and 5 squares labeled error.
5/10 = 0.5
0.5*100 = 50%
A model with 9 squares labeled exact value and 3 squares labeled error.
3/9 = 0.3333
0.3333*100 = 33.33%
A model with 8 squares labeled exact value and 4 squares labeled error.
4/8 = 0.5
0.5*100 = 50%

Graph y+9=−3x
Identify the x-intercept
Answer:
formula is y=mx+b
the b(y-intercept) is -3x and m(slope) is 9.
In the graph, you would start at -3x on the y-axis (since it's on the y-intercept)
put your dot on -3x and move up 9.
you should land on positive 7(on the y axis)
9 must be a fraction so it would be 9/1
so, move once to the right on positive 7.

how to solve 6r - 1 + 6r =11
Answer:
r = 1
Step-by-step explanation:
The equation is,
→ 6r - 1 + 6r = 11
Now the value of r will be,
→ 6r - 1 + 6r = 11
→ 12r = 11 + 1
→ r = 12/12
→ [ r = 1 ]
Hence, the value of r is 1.
Answer:
The answer is 1 r is equal to 1

The diagram shows the layout of the township playground. The playground committee is ordering rubber mulch to cover the playground surface.
A playground is made up of a rectangle and a triangle. The rectangle has a base of 40 feet and height of 25 feet. The triangle has a base of 22 feet and height of 20 feet.
One ton of mulch will cover 122 square feet at the needed depth. How many tons of mulch should the committee order?
The area of the rectangular section is
ft2.
The area of the triangular section is
ft2.
The total area of the playground is
ft2.
The committee should order
tons of mulch.
Step-by-step explanation:
Okay, so to figure out the area of a rectangle, the equation is base times height.
40*25=1000
So the area of the rectangle is 1000 square feet.
The formula for the area of a triangle is base times height divided by 2.
22*20=440
440/2=220
So the area of the triangle is 220 square feet.
Therefore, combining this, the total area of the playground is 1,220 square feet.
Since one ton of mulch covers 122 square feet, divide the total area of the playground by the amount 1 ton covers.
1220/122=10
You would need 10 tons of mulch to cover the playground.
a)The area of the rectangular section is 1000 ft2.
b)The area of the triangular section is 220 ft2.
c)The total area of the playground is 1220 ft2
d)The committee should order 10 tons of mulch.
What are the areas of a rectangle and a triangle?The area of a rectangle is the product of length and breadth while the area of a triangle is the half of the product of the base and the height.
The area of the rectangular part = 40*25 =1000 square feet
The area of the triangular part = 0.5*22*20 =220 square feet
Total area to cover =1000+220 =1220 square feet
Given that 1 ton of mulch will cover 122 square feet
Or, 122 square feet area will be covered by= 1 ton of mulch
So, 1 square feet area will be covered by= (1/122) ton of mulch
So, 1220 square feet area will be covered by=(1/122)*1220 =10 tons of mulch.
Thus, a)The area of the rectangular section is 1000 ft2.
b)The area of the triangular section is 220 ft2.
c)The total area of the playground is 1220 ft2
d)The committee should order 10 tons of mulch.

A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day

Q11) 25 - 3x
Step-by-step explanation:
Q9) Use slope intercept form, y = mx + b
To get m, you need choose any point on the line and use formula : Height / width. So the easiest point is to take height of 4 and width of 1. 4/1 = 4.

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Explanation:
The boxplot, aka box-and-whisker plot, is a visual way to represent summary data. Each piece of the boxplot visually tells us one of the five items of a five number summary, which are:
Min = smallest valueQ1 = first quartileMedian = middle most valueQ3 = third quartileMax = largest valueThe median is the vertical line inside the box of the boxplot. The diagram shows that the median is 25. Exactly half of the distribution is below the median, and the other half is above the median. So that means that 50% of the cars get at least 25 mpg.

2. What are the two Euclidean tools?
3. What is a line that divides a given line segment exactly into two halves forming 90 degrees angle at the intersection point?
4. What are the three parts of a compass that are discussed earlier?
5. What is the midpoint of line segment AB and line segment PQ?
6. What's the sign for intersecting lines?
7. What's the sign for parallel lines?
8. The compass and straightedge are known as?
9. What bisector divides a given angle into two angles of equal measures?
10. Why is it important to construct and bisect them step by step?
When a line is bi sected, it creates two arcs. The two Eu.c.li dean tools are the compass and straight edge. The line that divides a given line segment exactly into two halves forming a 90° angle at the intersection point is called the perpendicular bi sector.
What are the responses to other questions?The three parts of a compass are the h i n g e, the pencil or pen, and the adjustment s c r e w. The midpoint of a line segment AB is the point that is equidistant from A and B. The midpoint of a line segment PQ is the point that is equidistant from P and Q.
The sign for intersecting lines is an X at the point of intersection. The sign for parallel lines is two vertical lines that are equidistant and never intersect. The compass and straight edge are known as E.u.c.l.i dean tools. The bisector that divides a given angle into two angles of equal measures is called the angle bisector.
It is important to construct and bisect them step by step because it ensures accuracy and precision in the construction. Following a systematic approach helps to avoid errors and allows for easy replication of the construction.
