Answer:

r=1

Step-by-step explanation:

The correlation coefficient r = 0.8694 suggests a strong positive relationship between the variables, supporting reliable predictions using the regression line.

The correlation coefficient r = 0.8694 indicates a strong positive relationship between the average temperature and electricity costs.

With a value of r = 0.8694 and comparing it to the critical values from the table, r is significant, suggesting a reliable prediction using the regression line.

Therefore, the most likely value closest to the correlation coefficient of the data is r = 0.9.

Answer:

430 billion (430,000,000,000) is 4.3 x 10^11 in scientific notation

To convert 430 billion into scientific notation, express it as 4.3 multiplied by 100 billion. In scientific notation, 100 billion becomes 10^11. Therefore, the scientific notation of 430 billion is 4.3 x 10^11.

The process of writing large numbers or small numbers in scientific notation involves expressing the number as a product of a number between 1 and 10 (inclusive) and a power of 10. To write 430 billion dollars in scientific notation, firstly express it as 4.3 multiplied by 100 billion. In scientific notation, 100 billion is 10^11. So, Amazon's worth in scientific notation is 4.3 x 10^11.

Answer:

50% off would be $50

Step-by-step explanation:

20% + 30% = 50% original price was $100 but now with 50% off it is $50

Nike is having a sale $100 shoes is 30% off an additional discount 20% off. The amount to be paid for shoes now is $56.

Discount is the amount of off offered by the seller to the customer on a certain product. It is always offered as a percentage of the marked price of the product to lure the customer to buy the product.

Selling price is the price at which the product is finally sold. It is the marked price of the product minus the discount given.

Marked price = $100

initial discount = 30%

price of shoes becomes = $100 - 30% of $100 = [tex]100 - \frac{30}{100} *100 = 100- 30 = 70[/tex]

Additional discount offered =  20%

selling price of shoes = $70 - 20% of $70 = [tex]70 - \frac{20}{100} *70 = 56[/tex]

Step-by-step explanation:

Person A takes 2.3 days to paint the house working alone

Person B takes 13.8 days to paint the house working alone

Solution:

Let "x" be the number of days it takes person A  to paint the house

Person A can paint the neighbor's house 6 times as fast as Person B

Therefore.

Number of days it takes person B to paint the house = 6x

Their rates of painting are added to get  the rate working together

[tex]\frac{\text{1 house}}{\text{x days}} + \frac{\text{1 house}}{\text{6x days}} = \frac{\text{1 house}}{\text{2 days}}[/tex]

[tex]\frac{1}{x} + \frac{1}{6x} = \frac{1}{2}\\\\\frac{1 \times 6}{6x} + \frac{1}{6x} = \frac{1}{2}\\\\\frac{7}{6x} = \frac{1}{2}\\\\\ x = \frac{7}{3}= 2.3[/tex]

Thus person A takes 2.3 days to paint the house working alone

Person B = 2x = 6(2.3) = 13.8

Thus person B takes 13.8 days to paint the house working alone

∴He got interest from stock fund was = [tex]\frac{PRt}{100}[/tex]

                                                        =$[tex]\frac{x\times6.5\times2}{100}[/tex]   [here P =x , R = 6.5% and t = 2 yr]

                                                         =$  [tex]\frac{{13 x}}{{100} }[/tex]

Again he got interest from deposit was = [tex]\frac{PRt}{100}[/tex]

                                                               =$  [tex]\frac{(8000-x)\times 2.5\times\frac{18}{12} }{100}[/tex]     [here P = (8000-x), R=2.5% and t =[tex]\frac{18}{12} yr[/tex]]

According to problem

To solve the problem, two equations were set up and solved for the number of adult tickets (A). The equations A + S = 631 and S = A - 69 led to finding that 350 adult tickets were sold for the school play.

Explanation:

The school play ticket problem is a basic algebraic question involving setting up and solving equations. We need to determine the number of adult tickets and student tickets sold, given the total tickets and the difference between them.

Let's denote the number of adult tickets as A and the number of student tickets as S. According to the information provided:

A + S = 631 (The total number of tickets sold)

S = A - 69 (There were 69 fewer student tickets sold than adult tickets)

By substituting the second equation into the first, we get:

A + (A - 69) = 631

2A - 69 = 631

2A = 631 + 69

2A = 700

A = 350

So, 350 adult tickets were sold.

Answer:

h = [tex]\frac{2A}{b_{1}+b_{2} }[/tex]

Step-by-step explanation:

Given

A = [tex]\frac{1}{2}[/tex](b₁ + b₂)h

Multiply both sides by 2 to clear the fraction

2A = (b₁ + b₂)h

Divide both sides by (b₁ + b₂)

[tex]\frac{2A}{b_{1}+b_{2} }[/tex] = h

Answer:

211

Step-by-step explanation:

The total miles that Rachel's family travelled can be found to be 211 miles.

First day: 68 miles

Second day: 10 fewer miles than the first day, so:

= 68 miles - 10 miles

= 58 miles

Third day: 85 miles

Add up the miles traveled each day:

Total miles = 68 miles (first day) + 58 miles (second day) + 85 miles (third day)

Total miles = 211 miles

In conclusion, Rachel's family traveled a total of 211 miles over the three days of their car trip.

The student's question lacks necessary details to compute the surface area of the composite figure. Generally, surface area is calculated by summing the areas of each face. For cubes, multiply the area of one face by six and adjust for unexposed areas in composites.

The question asks for the total surface area of a composite figure, but the question does not give enough details about the specific shape or composition of the figure. Typically, to find the surface area of any 3-dimensional shape, you'd sum the areas of all the individual faces. For example, for a cube, you'd calculate the area of one face (side length squared) and multiply by 6, because a cube has 6 faces.

In this scenario, if the composite figure was a combination of cubes, you would calculate the total surface area by finding the surface area of each cube separately (surface area of a cube = 6 x side length squared) and then adjust for any faces that are not exposed. The total surface area is the sum of the surface areas of each part of the composite figure minus any overlapping areas.

Without the complete details of the figure, I cannot provide a numerical answer, but I hope this explanation helps you understand the steps involved in computing surface area for composite figures.

Step-by-step explanation:

We are to subtract u from v.

⇒ We have to take away 'u' from 'v'.

We get: 2(v - u)

⇒ 2v - 2u which is the required result.

Step-by-step explanation:

Base ten blocks is used to divide a two digit divisor as follows.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

To use Base ten blocks to divide a two digit divisor.

Now,

Let an example as;

156 ÷ 13 = 12

Use Base ten blocks to divide as;

We start with a squares of 100 as 10 groups, then place 3 more groups below the hundred to make 13 groups.

We have 26 left to split evenly to each group.

We get, 12 in each group.

Answer:

x = 84

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5, thus

sum = 180° × 3 = 540°

Sum the interior angles and equate to 540 for x

131 + 108 + 107 + 110 + x = 540, that is

456 + x = 540 ( subtract 456 from both sides )

x = 84

The total cost function for taking a passenger to the airport is C = 45 + 0.35M, where C is the total cost and M is the number of miles driven. The $45 is a fixed fee, and $0.35 is the charge per mile.

The student is interested in creating a function that models the total cost of taking a passenger to the airport. This function includes a fixed fee and a variable fee that depends on the number of miles driven. To model this, let C represent the total cost and M represent the miles driven.

The total cost C can be represented by the equation C = 45 + 0.35M. Here, the $45 is a fixed fee for using the vehicle, and $0.35 is the additional charge per mile driven.

C represents the total cost of the trip to the airport and M represents the number of miles driven to the airport.

I believe it is the fourth graph

Step-by-step explanation:

The only graph that correctly represents the exponential function f(x) = 2ˣ  is the fourth graph

The exponential function is given as:

f(x) = 2ˣ

Thus:

When x = -2, we have:

f(-2) = 2⁻²

f(-2) = 1/2² = 1/4

When x = -1, we have:

f(-1) = 2⁻¹

f(-1) = 1/2¹ = 1/2

When x = 0, we have:

f(0) = 2⁰

f(0) = 1

When x = 1, we have:

f(1) = 2¹

f(1) = 2

When x = 2, we have:

f(1) = 2²

f(1) = 4

Thus, the only graph that correctly represents these values is the fourth graph
