Jace measured a line to be 14 inches long. If the actual length of the line is
13.1 inches, then what was the percent error of the measurement, to the
nearest tenth of a percent?
Answer:
6.87022901%
Step-by-step explanation:
He measured 14 out of 13.1 inches. There is a difference of 0.9 inches when u subtract. He miscalculated by 0.9 out of 13.1. In a calculator you divide .9 by 13.1 you get 0.0687022901. Multiply by 100 to get the percent and round it to your desired decimal place.

at what value of x, the function 2x^3/3+2x^2-6x+4 is minimum
Answer:
x=1
Step-by-step explanation:
We are given that
[tex]\frac{2x^3}{3}+2x^2-6x+4[/tex]
We have to find the value of x for which function is minimum.
Differentiate w.r.t x
[tex]f'(x)=2x^2+4x-6[/tex]
Substitute f'(x)=0
[tex]2x^2+4x-6=0[/tex]
[tex]x^2+2x-3=0[/tex]
[tex]x^2+3x-x-3=0[/tex]
[tex]x(x+3)-1(x+3)=0[/tex]
[tex](x-1)(x+3)=0[/tex]
[tex]x=1,-3[/tex]
Again, differentiate w.r.t x
[tex]f''(x)=4x+4[/tex]
[tex]f''(1)=4(1)+4=8>0[/tex]
[tex]f''(-3)=4(-3)+4=-8<0[/tex]
Hence, the function is minimum at x=1
two circles have a common chord of 16 in. Their centers are 21 units apart from each other. One of the circles has a radius of 17 in.
a)Make an accurate diagram of this situation.
b)Find a possible radius measurement for the second circle.
Answer:
Half of cord 24/2 = 12
Step-by-step explanation:
In the circle with r = 13 we have 13^2 = 12^2 + a^2 where a = the distance from the centre of this circle to the cord. Thus a = 5. Then the distance from the cord to the other circle centre is 21 - 5 = 16. In the second circle you can write r2^2 = 16^2 + 12^2. The r2 = sqrt (400) = 20

This triangle has one side that lies on an extended line segment.
Based on this triangle, what statement about x is true?
x= 33 because 180 – 147 = 33
x = 62 because 147 – 85 = 62 and 85 + 62 = 147
x = 95 because 180 – 85 = 95 and 85 + 95 = 180
x = 118 because
180 147 + 85
33 + 85
=118
Answer:
B. x = 62 because 147 – 85 = 62 and 85 + 62 = 147
Step-by-step explanation:
We are given that
[tex]\angle ABC=85^{\circ}[/tex]
Exterior angle=[tex]147^{\circ}[/tex]
We have to find the value of x.
We know that
Exterior angle=Sum of opposite interior angles of triangle
Using the property
[tex]x+85=147[/tex]
Subtract 85 from both sides we get
[tex]x=147-85[/tex]
[tex]x=62[/tex]
Option B is true.
B. x = 62 because 147 – 85 = 62 and 85 + 62 = 147

Answer:
Non-response bias also known as Participation Bias
Step-by-step explanation:
The type of bias being demonstrated in this scenario is known as Non-response bias also known as Participation Bias. This is happening in this scenario because the individuals being surveyed have gone through the trauma of a car accident and survived it. To them they are stating that seat belts would not have helped since they do not want to believe that they could have done something to prevent their injuries. This causes them to say nothing or provide false information which ultimately ruins the results of the study.

hayden and jamie completed 20 math problems together, jamie completed 2 more than twice the number that hayden completed. Let p represent the number of math problems hayden completed. Write an equation that can be used to find the number of math problems that jamie completed.
Answer:
2p+2+p = 20
Step-by-step explanation:
Let p represent the number of Math problems Hayden completed.
Let 2p+2 represent the number of Math problems Jamie completed.
Next, we have to add them together so that the total Math problems they completed will be equal to 20.
Let's solve.
2p+2+p = 203p+2 = 203p = 20-23p = 18p = [tex]\frac{18}{3}[/tex]p = 6Therefore, Hayden completed 6 Math problems.
Next, we have to get how many problems Jamie completed.
Let's solve.
2p+2 = ?2(6)+2 = ?12+2 = ?14Therefore, Jamie completed 14 Math problems.
Let's check.
2p+2+p = 2014+6 = 2020 = 20It's correct!

Answer:
2.6 in
Step-by-step explanation:
From the question given above, the following data were obtained:
Volume (V) of cylinder = 258¾ in³
Height (h) of cylinder = 12 in
Radius (r) =.?
NOTE: Pi (π) = 3.14
The radius of the cylinder can be obtained as follow:
V = πr²h
258¾ = 3.14 × r² × 12
258.75 = 37.68 × r²
Divide both side by 37.68
r² = 258.75 / 37.68
Take the square root of both side
r = √(258.75 / 37.68)
r = 2.6 in
Therefore, the radius of the cylinder is 2.6 in.

Solve is for solving the answer, and check is for checking your work. Is it alright if anybody could solve it before an hour?
Answer:
1. x = 6 check: 3 * 6 = 18
2. x = -12 check: -12/3 = -4
3. x = 11 check: 11 * 11 = 121
4. y = -4 check: -8 * -4 = 32
Step-by-step explanation:
1. x=6 ( 3×6=18)
2. x = -12 (-12÷3 = -4)
3. x=11 (11×11=121)
4 y=-4 (-8 × -4 = 32)
Reflect a figure with vertices A(1,2) B (3,6), C(-1,2), and D(-2,-2)

B) B(3,6) --> B' (3,-6)
C) A(1,2) --> A' (1,-2)
D) D(-2,-2)--> D' (-2,2)
Answer:
1,2 = 1,negative2
3,6 = 3,negative 6
-1,2 = negative 1, negative 2
-2,-2 = negative2, 2
Step-by-step explanation:
Sorry all i could do was reflect the coordinates across the x-axis.
The figure reflected along x-axis will have vertices A(1, -2), B (3, -6), C(-1, -2), and D(-2, 2).
What is reflection along the x-axis?When we reflect a figure along the x-axis the coordinate point of y changes its sign, (x, y) becomes (x, - y).
Think of holding the x-axis with two fingers and rotating it.
Given, we reflect a figure with vertices A(1,2) B (3,6), C(-1,2), and D(-2,-2)
across the x-axis.
∴ The rotated coordinate will be A(1, -2), B (3, -6), C(-1, -2), and D(-2, 2).

A horse can run at a top speed of 18 1/5 miles in 1/3 hour. What is the unit rate of the top running speed of a horse in miles per hour?
Answer:
54.6
Step-by-step explanation:
(18⅕ miles)/(⅓ hour) = ((18⅕)×3 miles)/hour = 54.6 miles per hour
The unit rate of the top running speed of a horse in miles per hour is 54.6 miles per hour.
What is the unit rate?There is an independent quantity, and a quantity that depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called the rate of increment of dependent quantity per unit increment in independent quantity.
Speed can be calculated as the ratio of the distance traveled to the time taken by the object.
We have been given that horses can run at a top speed of 18⅕ miles in 1/3 hour.
Therefore, Distance = 18⅕ miles
Speed = 18⅕ miles in 1/3 hour.
Thus, we get;
Unit rate= (18⅕ miles) / (⅓ hour)
Unit rate = ((18⅕)×3 miles)/hour
Unit rate = 54.6 miles per hour
Therefore, the unit rate of the top running speed of a horse in miles per hour is 54.6 miles per hour.
