The greatest possible error for a measurement of 10 1/8 oz is ± 1/16 oz, considering that 1/8 oz is the smallest visible increment on the measuring scale.
Explanation:The greatest possible error in a measurement refers to the smallest unit that the measuring instrument can discern. In the case of the measurement 10 1/8 oz, we consider the precision of the measuring tool used.
If the smallest division the scale can measure to is 1/8 oz, then the greatest possible error in this case would be ± 1/16 oz. This is because 1/8 oz is the smallest increment visible on the scale, and the actual measurement could be halfway between two increments.
The concept of greatest possible error is critical in determining the accuracy and precision of a measurement. It helps to understand how reliable a given measurement is.
For example, when taking several measurements of the same quantity, like the weight of grocery items, there is often a small variation. This variation is a normal part of measuring and can be due to the limitations of the measuring tool or the person taking the measurement.
Final answer:
The greatest possible error for the measurement of 10 1/8 oz is +/- 1/16 oz, which accounts for the uncertainty of the least precise digit in the measurement.
Explanation:
When considering the greatest possible error for a measurement, it's important to understand that this refers to the uncertainty associated with the least precise digit of the measurement. For a measurement like 10 1/8 ounces, if we are using a standard measuring device that has graduations for every 1/8 of an ounce, then the greatest possible error is half of the smallest unit measured, which in this case is 1/16 of an ounce.
The reason for this is because when a measurement falls between two lines or markings, the measurer must estimate the value to the nearest possible marking. If the measurement is exactly on a line, or marking, there is no need to estimate, but if it is not, then the convention is to record the number to the nearest marking and recognize that there's a potential error up to half the distance to the next marking. So, for the given measurement of 10 1/8 ounces, the greatest possible error would be +/- 1/16 of an ounce.
1.) Is f(x)=2x^3 + 2x and odd function
2.) is -5x^3 - 4 and even function ?
3.) 4x-4 an even even function ?
Answer:
yes, no, no
Step-by-step explanation:
For odd functions : −f(x) = f(−x) for all x
For even functions :f(x) = f(−x) for all x
1) -f(x)= -2x^3 -2x
f(-x) = -2x^3-2x
yes
2 ) f(-x) = 5x^3 -4 ≠ f(x)
no
3 ) f(-x) = -4x -4 ≠ f(x)
no
1) [tex]f(-x) = -2x^3-2x[/tex]
The function [tex]f(x)=2x^3 + 2x[/tex] is odd function.
2 ) [tex]f(-x) = 5x^3 -4[/tex] ≠ f(x)
The function [tex]f(x) = -5x^3 - 4[/tex] is not even function.
3 ) f(-x) = -4x - 4 ≠ f(x)
The function f(x) = 4x - 4 is not an even even function.
What are an odd function and an even function?If we obtain an expression that exists equivalent to f(x), we have an even function; if we obtain an expression that stands equivalent to -f(x), we contain an odd function; and if neither occurs, it is neither!
For odd functions :
−f(x) = f(−x) for all x
For even functions :
f(x) = f(−x) for all x
1) [tex]f(-x) = -2x^3-2x[/tex]
Therefore, the function [tex]f(x)=2x^3 + 2x[/tex] is odd function.
2 ) [tex]f(-x) = 5x^3 -4[/tex] ≠ f(x)
Therefore, the function [tex]f(x) = -5x^3 - 4[/tex] is not even function.
3 ) f(-x) = -4x - 4 ≠ f(x)
Therefore, the function f(x) = 4x - 4 is not an even even function.

Which of these is the best deal? [Note: there are two pints in a quart, and four quarts in a gallon]
Question 6 options:
A)
one quart of milk for $1
B)
1 gallon of milk for $2
C)
two quarts of milk for $1.50
D)
One pint of milk for 50 cents
The best deal is Option B, one gallon of milk for $2, after comparing the cost per gallon of each option using the conversion factors for pints, quarts, and gallons.
Explanation:To determine which option is the best deal, we need to compare the price per gallon of milk for each option. We have been given that there are two pints in a quart, and four quarts in a gallon. Using this information, let's compare:
Option A: One quart of milk for $1. Since one quart is one fourth of a gallon, the cost per gallon would be 4 times $1, which is $4 per gallon.Option B: One gallon of milk for $2. This is already in gallons, so the cost per gallon is $2.Option C: Two quarts of milk for $1.50. Two quarts make up half a gallon, so to find the cost per gallon, we double $1.50, which results in $3 per gallon.Option D: One pint of milk for 50 cents. Since there are 8 pints in a gallon, the cost per gallon would be 8 times 50 cents, or $4 per gallon.Comparatively, Option B provides the lowest cost per gallon of milk, making it the best deal.

Solve the variable of x+9=37
Also, n-5=9
x + 9 = 37
To solve for x bring 9 to the right side by subtracting 9 to both sides (what you do on one side you must do to the other). Since 9 is being added on the left side, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.
x + 9 - 9 = 37 - 9
x + 0 = 28
x = 28
Check:
28 + 9 = 37
37 = 37
n - 5 = 9
To solve for n you must add 5 to both sides (what you do on one side you must do to the other). Since 5 is being subtracted, addition (the opposite of subtraction) will cancel it out (make it zero) from the left side and bring it over to the right side.
n - 5 + 5 = 9 + 5
n + 0 = 14
n = 14
Check:
14 - 5 = 9
9 = 9
Hope this helped!

Find the measure of angle eight in each triangle round each answer to the nearest 10th
Answer:
# m∠A = 65.3°
# m∠A = 25.8°
# m∠A = 22.7°
Step-by-step explanation:
* Lets revise the trigonometry function to solve the problem
- In any right angle triangle:
# The side opposite to the right angle is called the hypotenuse
# The other two sides are called the legs of the right angle
* If the name of the triangle is ABC, where B is the right angle
∴ The hypotenuse is AC
∴ AB and BC are the legs of the right angle
- ∠A and ∠C are two acute angles
- For angle A
# sin(A) = opposite/hypotenuse
∵ The opposite to ∠A is BC
∵ The hypotenuse is AC
∴ sin(A) = BC/AC
# cos(A) = adjacent/hypotenuse
∵ The adjacent to ∠A is AB
∵ The hypotenuse is AC
∴ cos(A) = AB/AC
# tan(A) = opposite/adjacent
∵ The opposite to ∠A is BC
∵ The adjacent to ∠A is AB
∴ tan(A) = BC/AB
* Lets solve the problems
# In Δ ABC
∵ m∠B = 90°
∵ AB = 2.3 ⇒ adjacent to angle A
∵ BC = 5 ⇒ apposite to angle A
- To find m∠A use the tangent function because we have opposite
and adjacent sides
∴ tan A = BC/AB
∴ tan A = 5/2.3 ⇒ use tan^-1 to find m∠A
∴ m∠A = [tex]tan^{-1}\frac{5}{2.3}=65.29756[/tex]
* m∠A = 65.3°
# In Δ ABD
∵ m∠B = 90°
∵ AB = 5.4 ⇒ adjacent to angle A
∵ DA = 6 ⇒ the hypotenuse
- To find m∠A use the cosine function because we have adjacent
and hypotenuse sides
∴ cos A = AB/DA
∴ cos A = 5.4/6 ⇒ use cos^-1 to find m∠A
∴ m∠A = [tex]cos^{-1}\frac{5.4}{6}=25.84193[/tex]
* m∠A = 25.8°
# In Δ ABE
∵ m∠B = 90°
∵ EB = 2.4 ⇒ opposite to angle A
∵ EA = 6.8 ⇒ the hypotenuse
- To find m∠A use the sine function because we have opposite
and hypotenuse sides
∴ sin A = EB/EA
∴ sin A = 2.4/6.8 ⇒ use sin^-1 to find m∠A
∴ m∠A = [tex]sin^{-1}\frac{2.4}{6.8}=22.6673[/tex]
* m∠A = 22.7°

A month ago, Kerry weighed 123 1/4 pounds. Now he weighs 120 1/2 pounds. How many pounds did he lose?
For this case we have to:
Initial weight = [tex]123 \frac {1} {4} = \frac {4 * 123 + 1} {4} = \frac {493} {4} = 123.25 \ pounds[/tex]
Final weight =[tex]120 \frac {1} {2} = \frac {2 * 120 + 1} {2} = \frac {241} {2} = 120.5 \ pounds[/tex]
We subtract to know how many pounds he lost:
[tex]123.25-120.5 = 2.75[/tex]
So, Kerry lost 2.75 pounds.
ANswer:
Kerry lost [tex]2 \frac {3} {4}[/tex] pounds.
Answer:[tex]2.75\ pounds[/tex] or [tex]2\frac{3}{4}\ pounds[/tex]
Step-by-step explanation:
You can convert the mixed numbers to decimal numbers. Divide the numerator by the denominator of the fraction and add it to the whole number part:
[tex]123\ \frac{1}{4}\ pounds=(123+0.25)\ pounds=123.25\ pounds[/tex]
[tex]120\ \frac{1}{2}\ pounds=(120+0.5)\ pounds=120.5\ pounds[/tex]
To calculate how many pounds Kerry lost, you need to subtract his weigth of a month ago and his actual weigth.
Therefore, you get that he lost:
[tex]pounds\ lost=123.25\ pounds-120.5\ pounds[/tex]
[tex]pounds\ lost=2.75\ pounds[/tex] or [tex]2\frac{3}{4}\ pounds[/tex]
Each angle measure of a regular polygon is 60°. What is the polygon?
Answer:
Triangle
Step-by-step explanation:
A regular polygon of n sides has interior angles of:
a = 180 (n-2) / n
Given a = 60:
60 = 180 (n-2) / n
n = 3 (n-2)
n = 3n - 6
6 = 2n
n = 3
The polygon has three sides, so it's a triangle.
A regular polygon with each angle measuring 60° is an equilateral triangle.
A regular polygon is a polygon with all sides and angles equal. To find the type of polygon where each angle measures 60°, we use the formula for the measure of each interior angle of a regular polygon, which is (n-2) x 180° / n, where n is the number of sides.
Let's solve for n:
Set the angle measure formula to 60°: (n-2) x 180° / n = 60°
Multiply both sides by n to clear the fraction: (n-2) x 180° = 60n
Distribute 180°: 180n - 360° = 60n
Move the terms involving n to one side: 180n - 60n = 360°
Simplify: 120n = 360°
Divide both sides by 120: n = 3
Therefore, a regular polygon with each angle measuring 60° is an equilateral triangle.
Shown below is a right angle triangle. Find the exact length of the side labeled y.

The equation of a function whose parent function, f(x) = x + 5, is shifted 3 units to the right will be; g(x) = x + 2
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that, the parent function f(x) = x + 5 is shifted 3 units to the right
If the function of x is translated horizontally to the right by h units, then the new function will be g(x) = f(x - h)
If the function of x is translated horizontally to the left by h units, then the new function will be g(x) = f(x + h)
Thus, f(x) = x + 5 is shifted 3 units to the right:
The new function is
g(x) = f(x - h)
Here h = 3
f(x) = x + 5

Final answer:
The correct equation after shifting the parent function f(x) = x + 5 three units to the right is g(x) = x + 2.
Explanation:
The equation of a function that is shifted 3 units to the right from its parent function, f(x) = x + 5, will incorporate that horizontal shift by subtracting 3 from the variable x before applying the rest of the function. Therefore, the new function, g(x), will have the form g(x) = (x - 3) + 5 which simplifies to g(x) = x + 2. This accounts for the fact that the input to the function is effectively 3 units greater for the same output as the original function.

Given : Fabian mixes orange juice with 4 cans of pineapple juice to make punch. Each can of pineapple juice holds 2 liters. He makes a total of 19 liters of punch.
To find : How many liters of orange juice did Fabian use to make the punch?
Solution :
Let x be the amount of orange juice.
There are 4 cans of pineapple juice.
Each can of pineapple juice holds 2 liters.
So, 4 cans can hold [tex]4\times 2=8[/tex] liter of pineapple juice.
Together they make x+8 liter.
He makes a total of 19 liters of punch.
i.e. [tex]x+8=19[/tex]
[tex]x=19-8[/tex]
[tex]x=11[/tex]
Therefore, Amount of orange juice did Fabian use to make the punch is 11 liter.
So, Option B is correct.
Write a function for reflection of point x,y across the y axis
Answer:
Reflection of point 0(x, y) about y-axis = (-x, y)
Step-by-step explanation:
Following are the rules for a counter clockwise rotation of 90 degrees about the origin for a point O(x,y):
1. Invert the sign of the value of x.
2. The value of y-coordinate remains the same.
For example, a point M(h,k) after reflection gives a point M'(-h,k) using the rules given above. The points on the x-y plane are shown in the image attached.
