The line that is the best model for the data is the line that passes mostly through the centre of the data. Therefore, it is most likely the plot in the top right.
Answer:Graph B (according to the figure attached to the answer) best model the data in the scatter plot.Step-by-step explanation:We know that a line of best fit also known as a trend line is the line that best represent the data points.

i.e. the points are closely related to the line.

Also, the other properties of a trend line are--

The magnitude of the negative and positive residual values must be same.

( i.e. Not all point could lie above the line and not all points could lie below the line )

( In graph A most of the points lie below the line.

Hence, Graph A is not the correct answer.

In graph  most of the points lie above the line.

Hence, Graph C could not be the best model.

In graph D most of the points lie above the line and hence it could not be the best model)

whereas in Graph B there are equal number of points above and below the line.

A rectangular quilt is 5 feet wide and 7 feet long. How many feet of lace are needed to cover the edges of the quilt?

Answers

P = 2L + 2W
L = 7
W = 5
P= ???
P = 2*7 + 2*5
P = 14 + 10
P = 24 feet of lace.

The rectangular quilt has length 7 feet and width as 5 feet.

In order to find the perimeter, we have this formula:

[tex] P = 2(l+w) [/tex]

Plugging these values in the formula:

[tex] P = 2(7+5) [/tex]

Perimeter = 24 feet.

So 24 feet of lace are needed to cover the edges of the quilt.

Seventy concert tickets were sold for $550. Each adult ticket cost $9 and each children's ticket cost $5. Find the number of adult tickets and the number of children's tickets sold.

Answers

Total tickets = 70
Total cost = $550

Adult's ticket = $9
Child's ticket = $5
Difference = 9 - 5 = $4

Assume all 70 are child's tickets
5 x 70 = 350

But the total cost was 550
550 - 350 = $200
The $200 must have come from Adult's tickets, which has a difference of $4.

200 ÷ 4 = 50
So there are 50 adult's tickets.

70 - 50 = 20
And there are 20 child's tickets.

There were 50 adult tickets and 20 children's tickets sold.

To determine the number of adult and children's concert tickets sold, we use a system of equations: x + y = 70 (total tickets) and 9x + 5y = 550 (total revenue). Solving these, we find 50 adult tickets and 20 children's tickets were sold.

To find the number of adult and children's concert tickets sold, given the total revenue and the price of each ticket, we can set up a system of linear equations. Let's define x as the number of adult tickets and y as the number of children's tickets. We are given that:

The total number of tickets sold is 70: x + y = 70The total revenue from the tickets sold is $550: 9x + 5y = 550

Now we have the following linear equations:

x + y = 709x + 5y = 550

We can solve this system using either the substitution or elimination method. For simplicity, we'll use the elimination method.

Multiply the first equation by 5 to match the coefficient of y in the second equation:

5x + 5y = 350

Now subtract the new equation from the second equation given:

(9x + 5y) - (5x + 5y) = 550 - 3504x = 200x = 50

Using the value of x in the first equation, we find y:

50 + y = 70y = 20

Therefore, there were 50 adult tickets and 20 children's tickets sold.

Answers

Hey there! 

To find the area of a parallelogram, you multiply the length and the width together, the exact same method you would use to find the area of a rectangle or square.

The reason you would use the same area formula of a rectangle/square to find the area of a parallelogram would be that all rectangles are parallelograms (however, not all parallelograms are rectangles).
**Rectangles are a special kind of parallelogram: they are parallelograms with right angles formed in the corners of the figure.

Another thing to keep in mind is to imagine this: if you were to split the parallelogram from the top left corner straight down, you will get a triangular figure. If you were to move this triangular figure to fill in the right slanted part of the parallelogram, you would have a rectangle.

Now, to solve for the area. Because the formula is A=Base (or the length)*Height (or the width), you should have this expression:
A=20*27

This would simplify to 540 cm squared, which would be your answer.

Hope this helps and have a wonderful day! :)

how can you tell before dividing that the first digit of the quotient 2,874/3 is in the hundreds place?

Answers

I can tell the answer is in the hundreds place by rounding 2874 into 3000 so 3000/3 is 1000 but you already know 2874 is less than 3000 so you know the quotient is gonna be a number that has a 9 in the hundreds place.

Final answer:

You can tell that the first digit of the quotient of 2,874 divided by 3 is in the hundreds place by using estimation and recognizing that 287 (the first three digits) is greater than 3 multiplied by 100, thus ensuring the quotient reaches the hundreds place.

Explanation:

To determine if the first digit of the quotient of 2,874 divided by 3 is in the hundreds place before actually dividing, we can use an estimation technique. Estimation helps us to predict the placement of the quotient's digits without doing the full calculation. For the divisor 3 to produce a number in the hundreds place, it must be able to go into the first three digits of the dividend (here, 2,874).

We look at the thousands and hundreds places of the dividend. Since the number 2,874 has a 2 in the thousands place, we know 3 cannot be divided into 2 to give us a number in the hundreds place. But when we include the next digit in the hundreds place, we have 287, which is greater than 3 imes 100. Therefore, we can say that 3 will go into 287 at least 100 times, making the first digit of the quotient in the hundreds place.

This estimation is further validated by the recognition that the number in the hundreds place of 2,874 (which is 8) is more than twice 3, and therefore, dividing it by 3 will definitely yield a number greater than 100 but less than 1,000.

Dennis is thinking of two number. The only common factors of the number are 1 and 3.Thier first common multiple is 18.One of the number is 9. What is the other number?

Answers

The other Number would be 6 due to the fact that since 1 of them is 9, you eliminate the numbers 18, 9, and 3, since they wouldn't meet the qualifications. Therefor, it must be 6 to have common factors 3 and 1, and the LCM ( Least Common Multiple ) will be 18

Final answer:

Dennis's other number, considering the conditions of only having 1 and 3 as common factors and 18 as the least common multiple with 9, is 6.

Explanation:

To solve the problem regarding Dennis's numbers, it's crucial to understand the conditions provided: the numbers only share common factors of 1 and 3, one of the numbers is 9, and their first common multiple is 18. To find the other number, knowing one of the numbers allows us to apply the rule of least common multiples (LCM). Since 9's factors are 1, 3, and 9, and the LCM with the other number is 18, this other number must be divisible by itself and 3 but not be a multiple of 9 to maintain the unique common factors condition. The only number that satisfies the condition in which 18 is the LCM and shares only 1 and 3 as common factors with 9, would be 6, since 18 is the smallest number that both 9 and 6 can divide into without other common multiples.

x=1.94
this is the answer because you subtract the 5 on both sides then divide by 8 which would be x^2=3.75, finally take the square root of both sides to get x=1.94 after rounding
8x² + 5 = 35
8x² = 35 - 5
8x² = 30
x² = 30/8
x² = 3.75
x = ±1.94  to the nearest hundredth

So x₁ = -1.94 and x₂ = 1.94

jerry was playing a video game. it took him 10 lives to beat the 2nd world, 5 times as many as it took him to beat the 1st world. how many lives did he use to the 1st world?

Answers

2nd world = 10 lives
lst world = 5 x 10 = 50 lives

Final answer:

Jerry used 2 lives to beat the 1st world, determined by dividing the 10 lives used for the 2nd world by 5.

Explanation:

Jerry used 10 lives to beat the 2nd world and it took him 5 times as many lives as it did to beat the 1st world. To find out how many lives it took him to beat the 1st world, we need to divide the number of lives used for the 2nd world by 5.

Let x represent the number of lives Jerry used to beat the 1st world. The equation based on the given information is:

5 * x = 10

Now, we solve for x:

x = 10 / 5

x = 2 lives

Therefore, Jerry used 2 lives to beat the 1st world.

The sequence is, in fact, quadratic. It is described by the equation

First differences are increasing, so the sequence will not be arithmetic. An arithmetic sequence has constant first differences.
