What is 80% of a 25 question test?; How many questions do you have to get right out of 20 to get 80 %?

Answers

Answer 1

To get 80% percentage you need to attempt 20 question

Percentage:

In mathematics, a percentage (from Latin: per centum, "by a hundred") is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%",although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number (pure number); it has no unit of measurement.

For example, 45% (read as "forty-five per cent") is equal to the fraction

45/100, the ratio 45:55 (or 45:100 when comparing to the total rather than the other portion), or 0.45. Percentages are often used to express a proportionate part of a total.

now we need to find  80% of a 25 question test

80% of 25 can be written as 80% × 25

= 80/100 × 25

= 20

What do you mean by functions?

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). Expressions of well-known functions can be found in many frequently used mathematical formulas. A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X.

The set X is called the domain of the function and the set Y is called the codomain of the function.

Given function:

f(x) = 3x - 5

For f(x-2) substitute x as (x-2) in given function

f(x-2) = 3(x - 2) - 5 = 3x - 6 - 5 = 3x - 11

The figure below is dilated by a factor of 4/3 centered at the origin. Plot the resulting image.

The geometric figure above has been dilated by a scale factor of 4/3 centered at the origin and plotted in the graph attached below.

What is dilation?

In Geometry, dilation can be defined as a type of transformation which typically changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.

Next, we would have to dilate the coordinates of the preimage by using a scale factor of 4/3 centered at the origin as follows:

Coordinate X (-3, -6) → Coordinate X' (-3 × 4/3, -6 × 4/3) = Coordinate A' (-4, -8).

Coordinate Y (3, 3) → Coordinate Y' (3 × 4/3, 3 × 4/3) = Coordinate A' (4, 4).

X²+ y²-14X + 8Y+ 40 = 0

Answers

We must transform the current polynomial to circle standard form: (x-h)^2+(y-k)^2=r^2. We will do so by completing the square, which produces a perfect square trinomial that can be factored into a square binomial in the form of the circle standard form.

First, use the commutative property to rearrange and group x and y:

x^2+(-14x)+y^2+8y+40=0

Now, we will subtract 40 from both sides:

x^2+(-14x)+y^2+8y=-40

We can now complete the square for both x and y:

(x^2-14x+(-14/2)^2)+(y^2+8y+(8/2)^2)=-40+(-14/2)^2+(8/2)^2

Simplify:

x^2-14x+49+y^2+8y+16=-40+49+16

Factor and simplify:

(x-7)^2+(y+4)^2=25

Now, factor the 25 to a squared factor:

(x-7)^2+(y+4)^2=5^2

The circle is now in standard form, so let’s identify its features:

Center: (h,k) = (7, -4)

Radius: 5

Vertices: (7, 1), (7, -9), (2, -4), (12, -4)

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the number be represented as A

Answers

Answer:

To answer these questions, we need to first calculate the total number of payments you have made over the past 3 years. We can do this by multiplying the number of payments per year (12) by the number of years (3). This gives us a total of 36 payments.

Next, we can use a financial calculator or spreadsheet program to solve for the remaining balance on your loan after making 36 payments of $327.51 each. In a financial calculator, we can enter the following values:

N: 36

I: 5.8

PV: -14000

PMT: 327.51

FV: 0

Solving for PV gives us a remaining balance of $4,819.56. Therefore, the answer to part A is $4,819.56.

To find your equity in the car, we can subtract the remaining balance on the loan from the value of the car. In this case, your equity would be $7,500.00 - $4,819.56 = $2,680.44. Therefore, the answer to part B is $2,680.44.

Answers

The confidence interval for the average age of the population would be (18.8, 25.2).

What is the confidence interval?

In frequentist statistics, a confidence interval is a range of estimates for an unknown parameter. A confidence interval is computed at a designated confidence level; the 95% confidence level is most common, but other levels, such as 90% or 99%, are sometimes used.

Given that,

Point estimate = sample mean = [tex]\bar x[/tex] =22

sample standard deviation = s = 6

sample size = n = 16

Degrees of freedom = df = n - 1 = 16 - 1 = 15

At 95% confidence level

[tex]\alpha[/tex] = 1 - 95%

[tex]\alpha[/tex] =1 - 0.95 =0.05

[tex]\alpha/2[/tex] = 0.025

[tex]t_{\alpha/2},df[/tex] = t 0.025 , 15 = 2.131

Margin of error = E = [tex]t\alpha/2,df * \frac{s}{\sqrt n}[/tex]

Answers

To prepare 24 ounces of a 10% hydrochloric acid solution, Doreen Schmidt needs to mix 24 * 10/100 = <<24*10/100=2.4>>2.4 ounces of hydrochloric acid with 24 - 2.4 = <<24-2.4=21.6>>21.6 ounces of water.

Let's say Doreen has 24 ounces of a 12% hydrochloric acid solution and wants to know how much of a 16% solution she needs to add to it to get the desired 10% solution.

The amount of hydrochloric acid in the 12% solution is 24 * 12/100 = <<24*12/100=2.88>>2.88 ounces.

To get the desired 10% solution, Doreen needs to add an additional 2.4 - 2.88 = -0.48 ounces of hydrochloric acid. Since she cannot add a negative amount, she needs to add hydrochloric acid from a 16% solution to the 12% solution.

To add 0.48 ounces of hydrochloric acid to the solution, Doreen needs to mix 0.48 / (16/100) = 0.3 ounces of a 16% hydrochloric acid solution with the 12% solution.

Therefore, Doreen needs to mix 24 ounces of a 12% hydrochloric acid solution with 0.3 ounces of a 16% solution to get the desired 10% solution.

find the dimensions (radius r and height h) of the cone of maximum volume that can be inscribed in a sphere of radius 2.

Answers

The dimensions of the radius is 4/3[tex]\sqrt{2}[/tex] and that of height is 8/3.

Let r be the radius of the cone,  be the radius of the sphere and h be the height of the cone.

Let's put DˆOB=x with limitations 0≤x≤π.

In the right-angled triangle DOB:

r=DB=Rsinx, OD=Rcosx, than

h=CD=OC+OD=R+Rcosx=R(1+cosx).

So the volume of the cone is:

V=1/3πr²h ⇒V=1/3π(Rsinx)²⋅R(1+cosx)

V=1/3πR³sin²x(1+cosx)

V'=1/3πR³⋅[2sinx⋅cosx⋅(1+cosx)+sin2x(−sinx)]

  =1/3πR³sinx[2cosx(1+cosx)−sin2x]

  =1/3πR³sinx(2cosx+2cos2x−sin2x)

  =1/3πR³sinx(2cosx+2cos2x−1+cos2x)

 =1/3πR³sinx(3cos2x+2cosx−1)

Now let's find the signum of the derivative, since sinx≥0 for every x in the limitations, then:

V'≥0⇒3cos²x+2cosx−1≥0

      ⇒Δ/4=(b/2)²−ac =1+3=4

cosx=(−b/2)±√Δ/4 / a

      =−1±2/3,

So:

cosx≤−1∨cosx≥1/3

The first one has only the solution:

x=π

the second:

−arccos(1/3)≤x≤arccos(1/3), but for the limitations:

0≤x≤arccos(1/3).

The function gros from zero to arccos(1/3), and then it decreases.

So x=arccos(1/3) is the maximum requested.

Let's find now r and h:

r=Rsinx

 =R√1−cos2x

 = 2√1−(1/3)²

 = 2√1−1/9

 =2√9−1/9

 =2√8/9

the Celisius and the Fahrenight temperature scales are relased by the equation c=5/6 (F-32) expresses F in terms of C.

Answers

Answer:

F = (9/5)C + 32

Step-by-step explanation:

C = 5/9(F-32)        **you wrote the fraction wrong in your question, it's 5/9, not 5/6

C = (5F)/9 - 160/9

C + 160/9 = (5F)/9

9C + 160 = 5F

(9C + 160)/5 = F

F = (9/5)C + 32

Answer:                   F = (6C/5) + 32

To express F in terms of C, rearrange the equation to isolate 'F'.

Inverse Operations

To rearrange the equation, we want 'F' to be by itself. To move numbers to the other side, we do the other pair of inverse operation to both sides. This cancels out what we don't need while keeping the left and right sides equal.

Pairs of inverse operations

Multiply ⇔ DivideAdd ⇔ Subtract

Calculate

[tex]\displaystyle { C = \frac{5}{6}*(F-32) }[/tex]                  Start with the equation in the question.

[tex]\displaystyle { C = \frac{5*(F-32)}{6} }[/tex]                  Rewrite. This is the same as the question.

[tex]\displaystyle { 6C = \frac{5*(F-32)}{6}*6 }\\[/tex]           Multiply both sides by 6.

[tex]\displaystyle { 6C = 5*(F-32) }[/tex]                 Cancelled out 6 on the right.

[tex]\\\displaystyle { \frac{6C}{5} = \frac{5*(F-32)}{5} }[/tex]                Divide both sides by 5.

[tex]\displaystyle { \frac{6C}{5} = (F-32) }[/tex]                      Cancelled out 5 on the right.

[tex]\displaystyle { \frac{6C}{5} = F-32 }[/tex]                         We don't need the brackets if 'F - 32' is alone.

[tex]\displaystyle { \frac{6C}{5}+32 = F-32+32 }[/tex]         Add 32 to both sides.

[tex]\displaystyle { \frac{6C}{5}+32 = F }[/tex]                         Cancelled out 32 on the right.

[tex]\displaystyle { F = \frac{6C}{5}+32 }[/tex]                         Keep lone variables on the left side.

Therefore, the equation to convert Celsius to Fahrenheit is:

           [tex]\displaystyle { F = \frac{6C}{5}+32 }[/tex]

Milo worked for 5 hours on Monday and 4 hours on Tuesday. he earned $14 per hour. How much money did milo earn on both days combined? show

your work

Answers

Answer:

$126

Step-by-step explanation:

Monday: 5HR X $14 = $70

Tuesday: 4HR X $14 = $56

$70+$56=$126

Since Milo earns the same amount ($14) no matter what day, the amount he makes is only dependent on the number of hours worked.
5 hours Monday =5x
4 hours Tuesday =4x
Total hours worked =9
X=$14
So…
5x+4x= total amount earned or 9x
5(14)+4(14)=$126

What does the number in the bottom right hand corner of a two-way frequency table represent?; What is a 2 way frequency table?; What are the important parts of a two-way frequency table?

Answers

The solutions for all three questions regarding two-way frequency tables are given below.

A two-way frequency table is a method used to visually represent two sets of categorical data. Unlike one-way frequency tables which have only one categorical variable, these have two. The important parts of a two-way frequency table are the topmost rows that have the name of the category. The leftmost column also has the categories listed. The middle columns and rows contain the data (frequency).

The number in the bottom right-hand corner of a two-way frequency is used to denote the total number of data points that are there in the data set given. This is also equal to the sum of the total rows/columns.
