Step-by-step explanation:

Answer:

A) mean = 1.2

B) median

C) The measures of center use data points to approximate a middle value or average of a given data set

Step-by-step explanation:

The “balance” process was developed to provide another way in which the mean characterizes the “center” of a distribution. 

The mean is the balance point of the data set when the data are shown as dots on a dot plot (or pennies on a ruler). 

A) The balance point for the points 0.4, 1.4, and 1.8. Will be

(0.4 + 1.4 + 1.8)/3 = 3.6/3 = 1.2

B) The median is the measure of center that is indicated by the center of balance

The median is the value in the center of the data. Half of the values are less than the median and half of the values are more than the median. It is probably the best measure of center to use in a skewed distribution.

C) A measure of central (measure of center tendency) is a value that describe a set of data by identifying the central position of the data set. The three measures of central tendency are the mean, median and mode.

Answer:

1. Their answers differ because of approximation

2. See Explanation Below

Step-by-step explanation:

Given

Allison

[tex]Morning: 2\frac{7}{8} miles[/tex]

[tex]Afternoon: 3\frac{3}{8} miles[/tex]

Total: About 6 miles

Jennifer

[tex]Morning: 3\frac{1}{10} miles[/tex]

[tex]Afternoon: 3\frac{3}{10} miles[/tex]

Total: [tex]6\frac{4}{10} miles[/tex]

Required

How their answers differ

To understand how their answers differ; first we need to calculate the actual miles they both ran.

Total = Distance covered in the morning + Distance covered in the evening

For Allison

Total Distance = [tex]2\frac{7}{8} + 3\frac{3}{8}[/tex]

Convert mixed fractions to improper fractions

Total Distance = [tex]\frac{23}{8} + \frac{27}{8}[/tex]

Take LCM and add

Total Distance = [tex]\frac{23 + 27}{8}[/tex]

Total Distance = [tex]\frac{50}{8}[/tex]

Total Distance = 6.25 miles

For Jennifer

Total Distance = [tex]3\frac{1}{10} + 3\frac{3}{10}[/tex]

Convert mixed fractions to improper fractions

Total Distance = [tex]\frac{31}{10} + \frac{33}{10}[/tex]

Take LCM and add

Total Distance = [tex]\frac{31 + 33}{10}[/tex]

Total Distance = [tex]\frac{64}{10}[/tex]

Convert to improper fraction

Total Distance = [tex]6\frac{4}{10} miles[/tex]

From the calculation above, the total distance ran by Allison is 6.25 miles and she said she ran about 6 miles; This means that she approximated the total distance she covered.

Also from the calculation above, the total distance ran by Jennifer is [tex]6\frac{4}{10} miles[/tex] and she said she ran [tex]6\frac{4}{10} miles[/tex]; This means that she gave the actual distance she ran.

Hence, their answers differ because of approximation

Why they are both correct?

As mentioned above, the difference in their answer is approximation.

Approximation is rightly allowed in measurements as long as one is giving the right approximated value.

For Allison; the approximation of 6.25 miles is 6 miles;

For Jennifer; she gave the actual distance she ran ([tex]6\frac{4}{10} miles[/tex])

Base on this, we can conclude that both are correct

it is 10% because 10 percent got better in the experiment

then, x-axis

then, 3

Triangle 1 is the image of triangle 2 reflected over the y-axis

Triangle 2 is the image of triangle 3 reflected over the x-axis.

Reflecting triangle 4 over the y-axis results in triangle 3.

A triangle is a three-sided polygon It is one of the most fundamental geometric forms.

Triangle 1 is on the opposite side of triangle 2. When the triangles are bisected, they contact the y-axis.

Triangle 2 is to the left of triangle 3. Triangle 3 is to the right of triangle 2. When the triangles are bisected, they contact the x-axis.

You may build the same form by "mirroring" triangle 4 across the y-axis, then rotating it 90 degrees and placing it at the same distance from the y-axis.

Hence, triangle 1 is the y-axis reflected image of triangle 2, triangle 2 is the x-axis reflected image of triangle 3, and triangle 3 is formed by reflecting triangle 4 over the y-axis.

Step-by-step explanation:

Triangles are similar if they have the same shape, but not necessarily the same size.

in this case we have

JK/MO = KL/ON = JL/MN

A) Use properties of similar triangles.

The measurement of angle J can be derived from triangle MNO.

Corresponding angle are congruent.

Angle J in triangle JKL correspond with angle M in triangle MNO.

Therefore:

Tangent M = opp/adj

tanM = 2/1.5

tanM = 1.3

M = tan-¹ 1.3

M = 52.43

J = M = 52.43°

B) MO in △MNO corresponds to JK in △JKL

C) JK/MO = KL/ON = JL/MN

find JL using Pythagoras theorem

JL² = KL² + JK²

JL² = 4²+3²

JL = √(16+8)

JL = 5

JK/MO = KL/ON = JL/MN

= 3/1.5 = 4/2 = 5/2.5 = 2/1

Therefore the ratio of larger triangle to small triangle is 2:1

Answer:

1) The resistance is 2 ohms.

2) The voltage is 4.95 V.

3) The current is 150 amps.

4) The resistance is 0.05 ohms.

Step-by-step explanation:

Using formula, [tex]\text{Resistance}=\frac{\text{Voltage}}{\text{Current}}[/tex]

1) A 12 V battery produces a current of 6 amps. What is the resistance  ?

Voltage - 12 V and Current - 6 amps

[tex]\text{Resistance}=\frac{12}{6}[/tex]

[tex]\text{Resistance}=2[/tex]

The resistance is 2 ohms.

2) Silver has a resistance of 0.0198 ohms. What voltage would produce a current of 250 amps?

Resistance - 0.0198 ohms and Current - 250 amps

[tex]0.0198=\frac{\text{Voltage}}{250}[/tex]

[tex]\text{Voltage}=0.0198\times 250[/tex]

[tex]\text{Voltage}=4.95[/tex]

The voltage is 4.95 V.

3) What is the current produced by a potential dillerence of 120 volts through a resistance of 0.8 ohms?

Resistance - 0.8 ohms and Voltage - 120 V

[tex]0.8=\frac{120}{\text{Current}}[/tex]

[tex]\text{Current}=\frac{120}{0.8}[/tex]

[tex]\text{Current}=150[/tex]

The current is 150 amps.

4) What resistance would produce a current of 120 amps liom a 6 V battery"?

Voltage - 6 V and Current - 120 amps

[tex]\text{Resistance}=\frac{6}{120}[/tex]

[tex]\text{Resistance}=0.05[/tex]

The resistance is 0.05 ohms.

150A is produced by a potential difference of 120 volts through a resistance of 0.8 ohms

Given the formula:

E = IR;

where E is the voltage in Volts, I is the current in Ampere and R is the resistance in Ohms.

a) E = 12V, I = 6A, hence:

12 = 6R

R = 2 Ohms

b) R = 0.0198 Ohm, I = 250A, hence:

E = IR = 0.0198 * 250 = 4.95 V

c) E = 120V, R = 0.8 Ohm

120 = 0.8I

I = 150A

d) I = 120A, E = 6V

E= IR

6 = 120R

R = 0.05 Ohm

Step-by-step explanation:

We can use the quadratic formula (also attached) to solve this. All we need to do is substitute for the values and solve the equation like below.

a = 2, b= 10, c = -12

correct option is B) log Subscript 12 Baseline one-half minus (log Subscript 12 Baseline 8 + log Subscript 12 Baseline w)

Step-by-step explanation:

Here we need to simplify a logarithmic expression and find which expression is equivalent to it . Let's find out:

We have ,

log Subscript 12 Baseline (StartFraction one-half Over 8 w EndFraction) or ,

⇒ [tex]Log_1_2(\frac{\frac{1}{2} }{8w} )[/tex]

We know that : [tex]Log(\frac{a}{b} )=Log(a)-Log(b)[/tex]

⇒ [tex]Log_1_2(\frac{1}{2}) - Log_1_2(8w)[/tex]

We know that : [tex]Log(ab) = Log(a)+Log(b)[/tex]

⇒ [tex]Log_1_2(\frac{1}{2}) -( Log_1_2(8)+Log_1_2(w))[/tex]

Therefore , correct option is B) log Subscript 12 Baseline one-half minus (log Subscript 12 Baseline 8 + log Subscript 12 Baseline w)

The expression that could be considered equivalent to logSubscript 12 Baseline (StartFraction one-half Over 8 w EndFraction would be:

B). log Subscript 12 Baseline one-half minus (log Subscript 12 Baseline 8 + log Subscript 12 Baseline w) or  [tex]Log_{12}(\frac{1}{2}) - (Log_{12}(8) + Log_{12}(w))[/tex]

Given that,

[tex]Log_{12} (\frac{1/2}{8w} )[/tex]

Using the expression,

[tex]Log({\frac{a}{b}) = Log (a) - Log(b)[/tex]

We get,

[tex]Log_{12} (\frac{1/2}{8w} )[/tex]

[tex]= Log_{12}(\frac{1}{2}) - Log_{12} (8w)[/tex]

Using expression [tex]Log(ab) = Log(a) + Log(b)[/tex]

∵ [tex]Log_{12}(\frac{1}{2}) - (Log_{12}(8) + Log_{12}(w))[/tex]

Thus, option B is the correct answer.

Well it was a lucky guess but the answer is 75

The value of c that makes the vertex the same is 75.

Option C is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The vertex of the function f(x) = 2x² + bx + c has an x-coordinate given by

-b/2a, where a = 2 is the coefficient of the x² term.

The x-coordinate of the vertex is x = -b/4.

To find the y-coordinate of the vertex, we can substitute this value of x into the function f(x) and simplify:

f(-b/4)

= 2(-b/4)² + b(-b/4) + c

= b²/8 - b²/4 + c

= -b²/8 + c

We want the vertex of the new function to be the same as the vertex of f(x), so the x-coordinate of the vertex should still be -b/4.

This means that the new function must have the form

g(x) = 2x² + bx + d, where d is a constant.

We want the y-coordinate of the vertex of g(x) to be the same as the y-coordinate of the vertex of f(x), which is -b^2/8 + c.

Therefore, we must have:

g(-b/4) = -b²/8 + c

Substituting the form of g(x) and simplifying:

2(-b/4)² + b(-b/4) + d = -b²/8 + c

Simplifying further:

-b²/8 + d = -b²/8 + c

d = c

This shows that the value of d (the constant term in the new function g(x)) must be the same as the value of c (the constant term in the original function f(x)) in order for the vertex of the new function to be the same as the vertex of f(x).

Therefore,

The value of c is 75.
