Answer:

s = 10w

Step-by-step explanation:

First we need to find the slope

Since the point goes through (0,0), the slope is y/x

Using the point (1,10)

10/1 = 10

The equation is

y = mx+b

The slope is m and the y intercept is b  

The slope is 10 and the b intercept is 0

y = 10x

Changing to the variables on the graph

s = 10w

Answer: Option 2

Step-by-step explanation:

[tex]\frac{15x^4y^-^2}{3x^2y^3}[/tex]

Divide 15 by 3 and substract the variables's exponents.

[tex]5x^4^-^2y^-^2^-^3[/tex]

Solve;

[tex]5x^2y^-^5[/tex]

or

[tex]\frac{5x^2}{y^5}[/tex]

The second option is correct. The resulting expression when the indices is simplified according to the law of indices is [tex]\frac{5x^2}{y^5}\\[/tex]

Given the indices expression;

[tex]\dfrac{15x^4y^{-2}}{3x^2y^3}[/tex]

Using the following laws of indices to solve the problem:

[tex]a^n \times a^m = a^{n+m}\\a^n \div a^m = a^{n-m}\\[/tex]

From the given indices

[tex]\dfrac{15x^4y^{-2}}{3x^2y^3}\\=\frac{15}{3} \times \frac{x^4}{x^2} \times \frac{y^{-2}}{y^3}\\= 5 \times x^{4-2} \times y^{-2-3}\\=5\times x^2y^{-5} \\= 5x^2y^{-5[/tex]

This can also be expressed as:

[tex]=5x^2 \times \frac{1}{y^5}\\= \frac{5x^2}{y^5}\\[/tex]

Step-by-step explanation:

Answer:

answer : 10

Step-by-step explanation:

Hey there!

First of all, let's count the sides that we can count.

Our shortest side is 8 units if you count the squares it covers.

Now we can do our other side, which is 15 units when you count.

Now, we need to find our third side, which is the longest. The longest side is the hypotenuse. Because this triangle is a right triangle (it has a ninety degree angle), we can use the Pythagorean Theorem to solve for this side.

The Pythagorean Theorem states that when a triangle is a right triangle, [tex]a^{2} +b^{2} =c^{2}[/tex], where a and b represent the legs, and c represents the hypotenuse.

So, what we will do now is take the sides we have and solve for our c.

[tex]8^{2} +15^{2} =c^{2} \\64+225=289=c^{2} \\c=\sqrt{289} \\c=17[/tex]

As you can see, we used the square root to undo the squared c.

Now, we add our three lengths to get our perimeter.

8+15+17=40

Therefore, our perimeter is 40 units.

I hope that this helps you! Have a wonderful day!

Answer:

$1676

Step-by-step explanation:

The town of Lantana need $14,000 for a new playground.

Lantana Elementary School raised $5,358.

Lantana Middle School raised $2,834.

Latana High School raised $4,132.

The total amount raised so far is:

$5358 + $2834 + $4132 = $12324

The amount left to raise is:

$14000 - $12324 = $1676

You need to raise $1676.

By adding the amounts raised by all three schools, which is $12,324, and subtracting from the goal of $14,000, we find that an additional $1,676 is needed to fund the new playground in Lantana.

To determine how much more money is needed to reach the $14,000 goal for a new playground in Lantana, we need to sum up the amounts raised by Lantana Elementary School, Lantana Middle School, and Lantana High School, and then subtract this total from the goal.

Lantana Elementary School raised: $5,358
Lantana Middle School raised: $2,834
Lantana High School raised: $4,132

Adding these amounts together we get:
$5,358 + $2,834 + $4,132 = $12,324

To find out how much more is needed:

$14,000 - $12,324 = $1,676

Therefore, the town of Lantana needs to raise an additional $1,676 to meet the goal for the new playground.

Answer:

Calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume.

Step-by-step explanation:

Answer:

cylinder volume formula

v = (π * r²) * h

Step-by-step explanation:

To calculate the volume of a cylinder we have to multiply the height by the area of ​​the circle that is the base

The area of ​​a circle is calculated with this formula (a = π * r²)

Let's do an example where the radius is 5.5ft  and the height is 13ft  to see how to calculate the volume

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 13ft

π = 3.14

r = radius = 5.5ft

v = (π * r²) * h

we replace the unknowns with the values we know

v = (3.14 * (5.5ft)²) * 13ft

v = (3.14 * 30.25ft²) * 13ft

v = 94.985ft² * 13ft

v = 1234.805ft³

The volume of the cylinder is 1234.805ft³

We have been given a conversion problem. We are asked to convert 46 pounds into grams.

First of all, we will convert pounds to kg.

We know that 1 kg is approximately 2.2 pounds.

[tex]\frac{46\text{ lb}}{1}\times \frac{1\text{ kg}}{2.2\text{ lb}}[/tex]

Now we will convert kg to grams.

We know that 1 kg equal 1000 grams.

[tex]\frac{46\text{ lb}}{1}\times \frac{1\text{ kg}}{2.2\text{ lb}}\times \frac{1000\text{ g}}{\text{1 kg}}[/tex]

Now we will cancel out common units that is kg with kg and pounds by pounds.

[tex]\frac{46}{1}\times \frac{1}{2.2}\times \frac{1000\text{ g}}{1}[/tex]

Now we will multiply the terms in numerator and denominator.

[tex]\frac{46\times1\times1000\text{ g}}{1\times2.2\times1}[/tex]

[tex]\frac{46,000\text{ g}}{2.2}[/tex]

[tex]\frac{46,000\text{ g}}{2.2}=20,909.0909\text{ g}\approx 20,909.1\text{ g}[/tex]

Therefore, 46 pounds are approximately 20,909.1 grams.

The converted value for the given conversion problem is 20,909.1 grams, which is determined by dimensional analysis.

The conversion problem is given as:

46 lb/1 × 1 kg/2.2 lb × 1000/1 kg

To convert 46 pounds (lb) to kilograms (kg) using dimensional analysis.

Start with the given value: 46 lb.

Multiply by the conversion factor of 1 kg/2.2 lb.

This ratio converts pounds to kilograms, where 1 kilogram is approximately equal to 2.2 pounds.

The lb unit cancels out, leaving you with the value in kilograms:

(46 lb) × (1 kg/2.2 lb) = 20.9091 kg (rounded to four decimal places).

Lastly, multiply by the conversion factor 1000/1 kg to convert the result to grams (since 1 kg = 1000 grams).

The final result is approximately 20,909.1 grams.

Answer:

The probability of a selected car being a 4 door car, given that the car has a sunroof = 0.40

Step-by-step explanation:

The complete question is presented in the attached image.

The conditional probability, of event A happening, given that event B has happened, P(A|B), is given mathematically as

P(A|B) = P(A n B) ÷ P(B)

So, the required probability of a selected car being a 4 door car, given that the car has a sunroof is given as

P (4 doors | sunroof)

= P (4 doors n sunroof) ÷ P(sunroof)

Note that the probability of an event is given as the number of elements in that event divided by the Total number of events.

P (4 doors n sunroof)

= n (4 doors n sunroof) ÷ n (total)

From the Venn Diagram in the attached image,

n (4 doors n sunroof) = 20 + 0 = 20

n (total) = 100

P (4 doors n sunroof) = (20/100) = 0.20

P(sunroof) = n(sunroof) ÷ n(total)

n(sunroof) = 12 + 18 + 20 + 0 = 50

n(total) = 100

P(sunroof) = (50/100) = 0.50

P (4 doors | sunroof)

= P (4 doors n sunroof) ÷ P(sunroof)

= (0.20/0.50) = 0.40

Hope this Helps!!!

To find the probability of a car having 4 doors given that it has a sunroof, we use conditional probability. The probability can be found by dividing the number of cars with both a sunroof and 4 doors by the total number of cars with a sunroof. In this case, the probability is 6/11.

To find the probability of a car having 4 doors given that it has a sunroof, we need to use the conditional probability formula, which is:

P(4 doors | sunroof) = P(4 doors and sunroof) / P(sunroof)

In this case, we know that 11 cars have a sunroof, 6 cars have 4 doors, and a total of 100 cars are parked at the business. Therefore:

P(4 doors and sunroof) = 6/100

P(sunroof) = 11/100

Substituting these values into the conditional probability formula, we get:

P(4 doors | sunroof) = (6/100) / (11/100)

Simplifying the expression gives us:

P(4 doors | sunroof) = 6/11

Therefore, the probability that a randomly selected car with a sunroof has 4 doors is 6/11.

Option C.

Step-by-step explanation:

Number of purple markers = 2

Number of black marker = 1

Number of red markers = 3

Number of yellow markers = 2

Number of blue markers = 2

Total number of markers = 10

Probability to select randomly a red marker = [tex]\frac{\text{Number of red markers}}{\text{Total number of markers}}[/tex]

                                                                         = [tex]P(red)=\frac{3}{10}[/tex]

Now we keep with us and randomly select a marker again.

So remaining markers with us = (10 - 1) = 9

Probability of the randomly selected marker to be yellow P(yellow)

= [tex]\frac{\text{Number of yellow markers}}{\text{Number of remaining markers}}[/tex]

= [tex]\frac{2}{9}[/tex]

Probability of both the events (selecting red AND yellow) = P(red) × P(yellow)

= [tex]\frac{3}{10}\times \frac{2}{9}[/tex]

= [tex]\frac{6}{90}[/tex]

= [tex]\frac{1}{15}[/tex]

Therefore,Option (C) will be the answer.

Answer:

I disagree with Marty!

Step-by-step explanation:

If Marty would have -$5 it would mean he owns that person $5. If you don't have money you don't owe anything.

For example:

Isaiah has $20 and then he spends $18 and he only has $2 left.

Isaiah doesn't have enough money for anything else or should've not bought anything to save his allowance.

As you can see Isaiah has spent 18 dollars. Therefore, if the person has to ask for the money back, he would have to own those $18.

Back to the problem, Marty would rather have -$5 than $0. If he would rather have -$5 it means he has to own the person.

Therefore Marty would rather have $0.

Sample Response: I disagree with Marty’s statement because negative numbers are less than 0, so having −$5 would mean I would owe $5 to someone.

The final part of the question is asking;

How much did all (99.7%) of the students spend on textbooks in a semester

Answer:

almost all (99.7%) of the students spent between $165 and $315 on textbooks in a semester.

Step-by-step explanation:

The standard deviation rule describes to us that for distributions that have the normal shape, approximately 99.7% of the observations fall within 3 standard deviations of the mean.

In this question, we are given that; Mean = 240 and Standard deviation= 25

So, 3 standard deviation below the mean = Mean - 3(standard deviation)

= 240 - (3 × 25)

= 240 - 75 = 165

Now, 3 standard deviation above the mean = Mean + 3 standard deviation = 240 + (3 × 25)

= 240 + 75 = 315

So, almost all (99.7%) of the students spent between $165 and $315 on textbooks in a semester.

Answer:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    11/15-(w-8/15)=0  

Step by step solution :

Step  1  :

            8

Simplify   ——

           15

Equation at the end of step  1  :

 11           8

 —— -  (w -  ——)  = 0  

 15          15

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  15  as the denominator :

         w     w • 15

    w =  —  =  ——————

         1       15  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

w • 15 - (8)     15w - 8

————————————  =  ———————

     15            15    

Equation at the end of step  2  :

 11    (15w - 8)

 —— -  —————————  = 0  

 15       15    

Step  3  :

           11

Simplify   ——

           15

Equation at the end of step  3  :

 11    (15w - 8)

 —— -  —————————  = 0  

 15       15    

Step  4  :

Adding fractions which have a common denominator :

4.1       Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

11 - ((15w-8))     19 - 15w

——————————————  =  ————————

      15              15    

Equation at the end of step  4  :

 19 - 15w

 ————————  = 0  

    15    

Step  5  :

When a fraction equals zero :

5.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 19-15w

 —————— • 15 = 0 • 15

   15  

Now, on the left hand side, the  15  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  19-15w  = 0

Solving a Single Variable Equation :

5.2      Solve  :    -15w+19 = 0  

Subtract  19  from both sides of the equation :  

                     -15w = -19

Multiply both sides of the equation by (-1) :  15w = 19

Divide both sides of the equation by 15:

                    w = 19/15 = 1.267

One solution was found :

                  w = 19/15 = 1.267
