Part A: Explain Why The X-coordinates Of The Points Where The Graphs Of The Equations Y = 4x And Y = (2024)

Given:

Actual volume of graduated cylinder (a cup) = 7.5 milliliters.

Han measures the volume of graduated cylinder = 7 milliliters.

To find:

The percent error for Han’s measurement.

Solution:

We have,

Actual volume = 7.5 milliliters

Incorrect volume = 7 milliliters

So, the error in the measurement of volume is

[tex]Error=7.5-7=0.5[/tex]

Now,

[tex]%\text{Error}=\dfrac{text{Error}}{\text{Actual value}}\times 100[/tex][tex]\text{Percent error}=\dfrac{\text{Error}}{\text{Actual value}}\times 100[/tex]

[tex]%\text{Error}=\dfrac{text{Error}}{\text{Actual value}}\times 100[/tex][tex]\text{Percent error}=\dfrac{\text{Error}}{\text{Actual value}}\times 100[/tex]

[tex]%\text{Error}=\dfrac{text{Error}}{\text{Actual value}}\times 100[/tex][tex]\text{Percent error}=\dfrac{0.5}{7.5}\times 100[/tex]

[tex]%\text{Error}=\dfrac{text{Error}}{\text{Actual value}}\times 100[/tex][tex]\text{Percent error}=\dfrac{50}{7.5}[/tex]

[tex]%\text{Error}=\dfrac{text{Error}}{\text{Actual value}}\times 100[/tex][tex]\text{Percent error}=6.6666667[/tex]

[tex]\text{Percent error}\approx 6.7\%[/tex]

The percent error for Han’s measurement is 6.7%.

Therefore, the correct option is D.

Answer:

The law of large numbers

Step-by-step explanation:

The Law of large numbers states that if we observe more and more reptitiions of any chance process, the proportion of times that a specific outcome occurs approaches a single value.

The experiment embarked upon by Joselyn involving the roll of a die for a large number of trials would illustrate an experiment which illustrates the law of large numbers.

The law of large numbers simply describes the repeated performance of an experiment for a large number of trials. The law states that, as the number of experimental trials is increased, the expected value of the experiment is approached.

In Joselyn's experiment, the expected value of obtaining a 5 is 1/6. Hence, as the number of trials increases, the probability of having 5 continually approaches 1/6.

Hence, the experiment illustrates the law of large numbers.

Answer:

The answer is -3*5-4= -15-4=-19. So given f(x)=5 then x=-19.

Step-by-step explanation:

So basically when it says f(5) that means we need to plug in x=5 into the equation -3x-4. So lets solve, -3*5-4=-19. I hope this helps if you need any clarfication please comment. Please dont tell me you are cheating on a quiz/test/assestment. Cheating does not help you by the way!

1/3 is the awnser

Step-by-step explanation:

1/3 is the common difference of the given arithmetic sequence.

What is common difference?

The common difference is the difference that exists in between each pair of terms that follow one another's sequence.

The given arithmetic sequence is,

4, 3²/₃, 3¹/3, 3 .......

To find common difference,

The difference between first two terms = 4 - 3²/₃ = 4-11/3 = 1/3

The difference between send and third term = 3²/₃-3¹/3 = 11/3 - 10/3 = 1/3

Step-by-step explanation:

Given:

[tex] \sqrt{x + 2y} = z [/tex]

Required:

Solve for y (make y the subject of the formula)

SOLUTION:

[tex] \sqrt{x + 2y} = z [/tex]

Square both sides

[tex] (\sqrt{x + 2y})^2 = z^2 [/tex]

[tex] x + 2y = z^2 [/tex]

Subtract both sides by x

[tex] 2y = z^2 - x [/tex]

Divide both sides by 2

[tex] y = \frac{z^2 - x}{2} [/tex]

Step-by-step explanation:

Where: 44 is the old value and 55 is the new value. In this case we have a positive change (increase) of 25 percent because the new value is greater than the old value.

The solution is 20 %

The percentage change from the first value to the second value is 20 %

What is Percentage Error?

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage error is the difference between the measured value and the true value , as a percentage of the true value

Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100

Given data ,

Let the percentage change from first value to the second value be = A

Now , the first value = 44

The second value = 55

The percentage change is calculated from the formula ,

Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100

Substituting the values in the equation , we get

Percentage Error = [ ( | 44 - 55 | ) / 55 ] x 100

On simplifying the equation , we get

Percentage Error = ( 11/55 ) x 100

Percentage Error = 100/5

Percentage Error = 20 %

Therefore , the value of A is 20 %

Hence , the percentage change from the original value is 20 %

Represent

Square Pizza with S Soft Drink with D

Such that

[tex]P(S) = 49\%[/tex]

[tex]P(D) = 71\%[/tex]

[tex]P(S\ and\ D) = 38\%[/tex]

Required

Determine if events S and D are independent

Two events S and D are independent if:

[tex]P(S\ and\ D) = P(S) * P(D)[/tex]

Substitute values for P(S) and P(D)

[tex]P(S\ and\ D) = 49\% * 71\%[/tex]

Convert to decimals

[tex]P(S\ and\ D) = 0.49 * 0.71[/tex]

[tex]P(S\ and\ D) = 0.3479[/tex]

Convert to percentage

[tex]P(S\ and\ D) = 0.3479 * 100\%[/tex]

[tex]P(S\ and\ D) = 34.79\%[/tex]

The calculated P(S and D) is not equal to 38%

Hence, the events are not independent.

Answer:

y = 1/9 x z^3

Step-by-step explanation:

y is jointly proportional to x and z^3

y = k * x * z^3 where k is the constant of proportionality

y =12, x = 4 and z =3

12 = k * 4 * 3^3

12 = k * 4 * 27

12 = k * 108

12/108 = k

1/9 = k

y = 1/9 x z^3
