Kyla should babysit for 9.5 hours to buy the dress.

Double number line represents the comparison of numbers by representing them in equal ratio. The required double number line for the question is attached as figure.

The row I indicates the amount earned and row II indicates the number of hours Kyla should babysit. As is evident from the double number line, the average of last two amounts is the amount required by Kyla. Calculations are as follows -

Required amount = (49.5 + 55)/2

Required amount = 52.25

Now, the time between last two columns of row II will also be taken as average for calculation. So, time required to earn 52.25 after earning 49.5: (9 + 10)/2

Time = 0.5

Total time required to babysit = 9 + 0.5

Total time = 9.5 hours

Thus, Kyla should babysit for 9.5 hours to buy the dress.

The probability that the inspector finds exactly one nonconforming part is 0.4091.

Combination is a selection of items from a collection in which the order of selection is irrelevant. Probability is defined as the ratio of favorable outcomes to total outcomes.

Now, according to the question;

Let X represent the event in which the inspector discovers a nonconforming part.

An inspector selects three parts at random from among the twelve, and two cavities have been affected by a temperature malfunction, resulting in parts that do not meet specifications.

The total number of ways to select three parts from a total of twelve is ¹²C₃ = 220.

The number of possible ways for an inspector to identify just one defective part is:

²C₁×¹⁰C₂ = 2×45

²C₁×¹⁰C₂ = 90

The likelihood that the inspector will discover exactly one nonconforming part is provided by:

P (x=1) = (²C₁×¹⁰C₂)/¹²C₃

          = 99/220

P (x=1) = 0.4091

The inspector has a 0.4091 chance of finding exactly one nonconforming part.

Now, the probability that inspector finds no nonconforming parts is given by:

P (x=0) = ¹⁰C₃×¹²C₃

           = 120/220

P (x=0) = 0.5455

Therefore, the inspector has a 0.5455 chance of finding exactly none nonconforming part.

For a standard television of width 15 inches the correct options are

A. h/15=3/4, D) 15/h=4/3 and F) 4/15=3/h​.

Ratio is comparison between two or more quantities in simplest form.

The ratio of screen has a width to height ratio of 4:3.

We know a:b can be written as a/b.

∴ width:height = 4:3 can be written as (width/height) = (4/3).

So, Width = (4/3)height or Height = (3/4)width.

Given the height of a standard television is 15 inches.

So, 15 = (4/3)h or  h/15=3/4 or  15/h=4/3 or 4/15=3/h​.

Let's solve your equation step-by-step.

|x+8|=|2x+1|

Solve Absolute Value.

|x+8|=|2x+1|

We know eitherx+8=2x+1orx+8=−(2x+1)

x+8=2x+1(Possibility 1)

x+8−2x=2x+1−2x(Subtract 2x from both sides)

−x+8=1

−x+8−8=1−8(Subtract 8 from both sides)

−x=−7

−x/−1 = −7/−1

(Divide both sides by -1)

x=7

x+8=−(2x+1)(Possibility 2)

The equation in slope intercept form to represent the relationship is y = 12x + 15

An equation is an expression that shows the relationship between two or more numbers and variables.

The standard equation of a line is:

y = mx + b

Where m is the slope (rate of change) and b is the initial value of y.

Let y represent the total amount paid for renting a boat for x hours.

From the table, using the points (1, 27) and (3, 51):

The equation of the line is given as:

The equation can be modelled to a real scenario where every purchase can be use to calculate sales tax.

The equation to be modelled is as follows:

y = 1 / 20x

let

x = The total price of purchases

y = The  amount of sales tax

This simply means a person pays 1 / 20 or 5% of every purchase he/she makes.

The total price of the purchase(including tax) is x while the actual amount of tax paid is y.

Let's say you buy a goods worth 400 dollars. Let's calculated the tax as follows:

x = $400

Therefore,

y = 1 / 20 × 400

y = 1 / 20 × 400

y = $20

Hence, the tax for a purchase of 400 dollars is 20 dollars.

The probability that Alysha will win the bet is 0.12013

Let ‘x’ be the number of cute boys from next 20 persons that enter the library

And assume x be the integral values from 0 to 20

Given, the probability is 50% that the next person that enters the library is a cute boy,

total number of trials n=20 and probability of success p=50% = 0.5 = 1/2.

Hence, the p.m.f of X is given by

fX(x) = 20Cx(1/2)x(1−1/2)20−x

=20Cx(1/2)x(1/2)20−x

=20Cx(1/2)20

=20!(20−x)!x!⋅ 1220

=0,1,2,…,19,20

and the probability that X=x,

thus

P(X=x)=20!(20−x)!x!⋅1220

x=0,1,2,…,19,20

P(X=x)=20!(20−x)!x!⋅1220

x=0,1,2,…,19,20.

In particular, for X=x=12

P(X=12)=20!(20−12)!12!⋅1220

=20!8!12!⋅1220

≈0.12013

Hence, the probability that exactly 12 persons of the next 20 persons that walk into the library are cute boys is only approximately 0.12013.

Therefore, 0.1203 is less than 0.5, then it is more probable that Alysha will lose the bet than win it.

Step-by-step explanation: u just round it

For the given function f(x) = x^2 - 2x + 1, the difference quotient is {2x + h - 2]

Here we have the function f(x) = x^2 - 2x + 1

And we want to find the difference quotient, which is:

( f(x + h) - f(x))/h

Replacing the actual function there we get:

[ (x + h)^2 - 2*(x + h) + 1 - x^2 + 2x - 1]/h

Now we can simplify the numerator, we will get:

[ x^2 + 2xh + h^2 - 2x - 2h + 1 - x^2 + 2x  -1]/h

[2xh + h^2 - 2h]/h

Taking the quotient we get:

{2x + h - 2]

That is the difference quotient for the function f(x).

17 times theo will need to measure the flour for  both the recipes.

Children can use the acronym BODMAS to help them remember the right order to carry out mathematical operations while solving problems. B-Brackets, O-Orders (powers/exponents or roots), D-Division, M-Multiplication, A-Addition, and S-Subtraction are all abbreviated as BODMAS.

The order of operations (or operator precedence) in mathematics and computer programming refers to a set of rules that represent standards for which operations to carry out first in order to evaluate a specific mathematical expression. For instance, since the advent of contemporary algebraic notation, multiplication has been given a higher priority than addition in mathematics and most computer languages.

As a result, 1 + (2 3) = 7 rather than 1 + (2 3) = 9 is the value assigned to the expression 1 + 2 3. Exponents were first used in the 16th and 17th centuries, when addition and multiplication were given priority. Exponents could only be used as a superscript to the right of their base. Consequently, 3 + 52 = 28 and 3 52 = 75.

first add the total amount of flour =

   =   [tex]1\frac{1}{2} + 2\frac{3}{4}[/tex]

The standard form the linear function is f(x)= -3x-3.

An equation can be represented by a linear function. The standard form for the linear equation is: y= mx+b , for example, y=5x+3. Where:

m= the slope. It can be calculated for Δy/Δx .

b= the constant term that represents the y-intercept.

For the given example: m=5 and b=3.

You should replace in the minimum two given values for x and y in the standard form for a linear equation mx+b . Thus, you will write a system linear where from it, you can find the coefficients m and b. See below.

       y=mx+b

      -3=0*m+b

      -3=b

       y=mx+b

      3= -2*m+b

Now, you find b=-3, then

      3= -2*m-3

      3+3= -2m

       6=-2m

       m= -3

Thus, you can write f(x)= -3x-3.

Answer:

Explained through Step-by-step (Showed Work)

Step-by-step explanation:

Question: Show how 2/5 + 4/10 is the same as 4/5

Step-by-step:

2/5 and 4/10 are fractions. (So is 4/5)

To add fractions together, we need the denominators to be the same. This means that the bottom number of 2/5, which is 5 and the bottom number of 4/10 which is 10 have to be the same.

The easiest way to do this is to simplify 4/10. To simplify 4/10, we divide both the numerator (top number) and the denominator (bottom number) by the Greatest Common Factor.

In this case, 2 is the Greatest Common Factor because 4 divided by 2 is 2 and 10 divided by 2 is 5.

so, 4/10 can be simplified to 2/5.

Now, we can add 2/5 and 2/5 together by only adding the numerators. 2 + 2 = 4

so, 2/5 + 2/5 = 4/5

4/5 = 4/5

Therefore, 2/5 + 4/10 is the same as 4/5.

Hope this helps
