Which model represents a percent error of 25%? A model with 12 squares labeled exact value and 3 squares labeled error. A model with 10 squares labeled exact value and 5 squares labeled error. A model with 9 squares labeled exact value and 3 squares labeled error. A model with 8 squares labeled exact value and 4 squares labeled error.

Answers

Answer 1

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

Answers

one point would be on (0,9) and the other on (1,12)

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

The diagram shows the layout of the township playground. The playground committee is ordering rubber

Answers

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.

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).

Answers

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.

Answers

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.
