Ron bought 40 pen sets and sold 25. This year he bought 75 pen sets and sold 60. The absolute error each year was the same. Are the percent errors also the same? Explain using the solutions.

Answers

Answer 1

Absolute error is defined as the magnitude of the difference between the exact value and the approximation.

Here both the times, the error is 15.

40-25=15 and 75-60=15

No, the percent error is not same because the exact values are different and hence, the percent error is different.

Percent error value in 1st case is :

[tex]40-25=15[/tex]

error percent is= [tex]\frac{15}{40}\times100=37.5[/tex]%

Percent error value in 2nd case:

[tex]75-60=15[/tex]

error percent is=[tex]\frac{15}{75}\times100=20[/tex]%


Answer 2

The percent error compares the absolute error

Mr. Moore has 21 feet of wallpaper he cuts it into sections that are each 3 feet long how many

Answers

Total = 21 feet

if each is 3 feet

21/3 = 7

Therefore, there are 7 sections

Mathematics defines division as breaking into parts a larger unit to make several smaller units.

Division of 21 feet wallpaper into 3 feet section will give 7 small parts of the wallpaper.

To reach above answer, following calculation was made:

[tex]\begin{aligned} \rm Total\: length\:of \: the \:wallpaper &= 21\rm \:centimetres\\Length \:of\:each\:section &= 3\: \rm centimetres\end[/tex]

Therefore, number of sections will be the division of total length to length of each section.

[tex]\rm \begin{aligned} Number \:of \:sections &= \dfrac{\rmTotal\: length}{\rmLength\:of\:each\:section}\\ \\&= \dfrac{\rm 21\:centimetres}{\rm 3\:centimetres}\\\\&= \rm 7 \:sections \end[/tex]

Hence, 21 centimetres long wallpaper can be divided into 7 sections that are 3 centimetres long.

Answer: 65

The sum of [tex]2^4[/tex] and [tex]7^2[/tex] in standard form is [tex]6.5 \times 10^1[/tex].

To find the sum of [tex]2^4[/tex] and [tex]7^2[/tex] and write the answer in standard form, follow these steps:

Calculate [tex]2^4[/tex]:
[tex]2^4 = 2 \times 2 \times 2 \times 2 = 16[/tex]

Answers

The answer should be x+x+x+x=y or it can be 4x=y.

Since 1A claims that the diagram is of a square, you can easily find the perimeter by multiplying just one side by 4, because the definition of a square says that all of its four sides are equal in length.

Take the left side, x and 4, and add them together, because both of these lengths add up to form the side of the square. You have found one side of the square, x + 4. Now multiply this side by 4 for the perimeter.

Perimeter is the length all around the figure, and since a square has 4 sides you would multiply one side by 4 to find the perimeter.

4(x + 4) is your expression for the perimeter of the square. You could probably solve 1B and 1C by substituting in 3 and 5 for x in the equation I've given you :)

1. Refer to the equation y = 1/3 x + 2

(a)Create a table of x, y values for 4 ordered pairs. Tip: choose an x, then find y four times. Use “easy numbers”, like x = 0, 3 (gets rid of fraction), or -3

Answers

The final table is in the attached picture.

Before beginning, you should note that:

To get rid of a fraction, this fraction should be multiplied that is equal to or is a multiple of its denominator.

This means that:

[tex]\frac{1}{y} * ay = a[/tex]

Now, for the given:

We have the equation: [tex]y = \frac{1}{3} x + 2[/tex]

The denominator of the fraction is 3, therefore to get rid of it we will need x to be a 3 or a multiple of 3.

Let's consider the x values to be -3, 0, 3 and 6.

For x = -3: [tex]y = \frac{1}{3} (-3) + 2[/tex] = -3 + 2 = -1 .....>First order pair is (-3,-1)

For x = 0: [tex]y = \frac{1}{3} (0) + 2[/tex] = 0 + 2 = 2 .....> Second order pair is (0,2)

For x = 3: [tex]y = \frac{1}{3} (3) + 2[/tex] = 1 + 2 = 3 .....> Third order pair is (3,3)

For x = 6: [tex]y = \frac{1}{3} (6) + 2[/tex] = 2 + 2 = 4 .....> Fourth order pair is (6,4)

The triangular region shows the number of possible carnations, x, and the number of possible daisies, y, that can be used in a floral arrangement. The ordered pairs represent combinations of carnations and daisies that can be used in the floral arrangement.

Which ordered pairs make sense in the context of the situation?

Select each correct answer.


A) (6,8.5)

B) (7,5)

C) (13.5,6)

D) (12,5)

E) (14,7)

Answers

(7, 5) and (14, 7)  are inside the shaded region. I would rule out  those which are not whole numbers ( 1/2 a daisy would look silly!)

Answer (7, 5) and (14, 7)

we know that

If a ordered pair is a solution of the combination of carnations and daisies that can be used in the floral arrangement

then

the ordered pair must be in the triangular region graphed and make sense in the context of the situation

using a graphing tool

we're going to proceed to graph and analyze each of the cases

see the attached figure to better understand the problem

Step 1

point [tex]A(6,8.5)[/tex]

The point A is on the triangular region, but the number of daisies is not a whole number

therefore

The ordered pair A  does not make sense in the context of the situation

Step 2

point [tex]B(7,5)[/tex]

The point B is on the triangular region, and the number of carnations and daisies are a whole number

therefore

The ordered pair B  makes sense in the context of the situation

Step 3

point [tex]C(13,5.6)[/tex]

The point C is on the triangular region, but the number of daisies is not a whole number

therefore

The ordered pair C  does not make sense in the context of the situation

Step 4

point [tex]D(12,5)[/tex]

The point D is not on the triangular region

therefore

The ordered pair D  does not make sense in the context of the situation

Step 5

point [tex]E(14,7)[/tex]

The point E is on the triangular region, and the number of carnations and daisies are a whole number

therefore

The ordered pair E  makes sense in the context of the situation

The answer is

[tex]B(7,5)[/tex]

Which of the numbers below correctly describes 63.45 Mhz? Select one: a. 0.06345 Ghz b. 63,450 khz c. Both a and b d. None of the above

Answers

To solve this question, let us take one part at a time.

Part 1 (MHz to GHz)

We know that 1 MHz=0.01 GHz

Therefore, [tex]63.45 MHz=63.45\times 0.001 GHz=0.06345 GHz[/tex]

Thus, for the time being we know that Option A is correct.

Part 2 (MHz to KHz)

We know that 1 MHz=1000 KHz

Therefore, [tex]63.45 MHz=63.45\times 1000 KHz=63450 KHz[/tex]

Thus, Option B too is correct.

Therefore, Both A and B are correct. Thus, out of the given options, Option C is correct.

James is solving the equation x^2+10x=50 by completing the square. What number must be added to both sides of the equation to complete the square?

Answers

Let f (x) be a quadratic equation of the form:

[tex]x^2+bx+c\\[/tex]

Where b and c are real numbers.

So a generic procedure for completing squares is:

1) identify b

In this case b = 10

2) divide b between 2 and then square it

[tex](\frac{b}{2})^ 2\\[/tex]

[tex](\frac{10}{2})^ 2=25\\[/tex]

3) Add and subtract [tex]b ^ 2[/tex] in the equation

[tex]x ^2+10x + 25 - 25 = 50\\[/tex]

[tex]x ^ 2 + 10x +25 = 75\\[/tex]

4) Rewrite the equation as follows

[tex](x+\frac{b}{2})^2=c\\[/tex]

[tex](x + 5) ^ 2 = 75\\[/tex]

The number that you must add to both sides of the equation is number [tex]25 = (\frac{b}{2})^2[/tex]

The completed form of the equation is (x + 5)² = 75.

To solve the equation x² + 10x = 50 by completing the square, you need to add a specific number to both sides to create a perfect square trinomial on the left side. Here’s how you do it step-by-step:

Start with the equation: x² + 10x = 50.Take the coefficient of the x term (which is 10), divide it by 2, and then square the result: (10/2)² = 25.Add 25 to both sides of the equation: x²+ 10x + 25 = 50 + 25.Now the left-hand side of the equation can be factored as a perfect square trinomial: (x + 5)² = 75.

Therefore, the number that must be added to both sides to complete the square is 25.

A dairy needs 392 gallons of milk containing 5% butterfat. How many gallons each of milk containing 6% butterfat and milk containing 2% butterfat must be used to obtain the desired 392 gallons?

Answers

                       Qty                    %                       Qty * %

Solution 1:        x                 6% = 0.06        =      0.06x

Solution 2:    392 - x         2% = 0.02        =      0.02(392 - x)  = 7.84 - 0.02x

Mixture:          392              5% = 0.05        =     0.06x + 7.84 - 0.02x

                                                 392(0.05)   =    0.08x + 7.84

                                                           19.6   =    0.08x + 7.84

                                                          11.76   =    0.08x

                                                            147    =      x

Solution 2:  392 - x    = 392 - (147)   = 245

Answer: 147 gallons 6% and 245 gallons of 2%

{x*0.02+0.06y=392*0.05

{x+y=392, x=392-y

0.04y=11.76, y=294; x=392-294=98
