Help me out please with this question

Answer:

Let 'x' and 'y' be two different numbers.

Leila says that 75% of a number will always be greater than 50% of a number. The inequality that represents this statement is the following:

0.75x > 0.5y

Let x = 100 and y=200. We have that:

0.75(100) > 0.5(200)

75 > 100 ❌ INCORRECT ❌

Given that we found a case in which 75% of a number is not greater than 50% of a number, we can conclude that Leila's claim is incorrect.

Answer:

consistent.

Step-by-step explanation:

Consistent solution: When two lines cut at one point. The solution of system of equation is unique.Then, the solution is consistent.

Equivalent solution: When two lines are coincide then, system of equation is equivalent.

In other words, the solution set of two equation are same then, the equation is called equivalent system.

Inconsistent solution: The  system of equation is called inconsistent when there is no solution or lines do not cross .

In given figure, two lines cross at point (3,2).

Therefore, there is one solution of system of equation.

Hence, the system of equation is consistent.

The range of the data set (22, 28, 41, 42) is calculated by subtracting the smallest number from the largest, resulting in a range of 20.

Explanation:

The question asks for the range of a given data set. The range of a set of numbers is the difference between the largest and smallest numbers. In the provided list of numbers: 22, 28, 41, 42, the smallest value is 22 and the largest is 42.

To calculate the range, you subtract the smallest number from the largest number:

Range = Largest number - Smallest number
Range = 42 - 22
Range = 20

Therefore, the range of the data is 20.

Answer:

pic has correct graph

domain and range in the highlighted pic are right

the relation is a function

Step-by-step explanation:

y=2x+5 has y-intercept 5 and slope 2

You have the correct pic for that.

The domain is the values of x that relation takes on, it takes on all real numbers so you have that part right.

The range is the values of y that relation takes on, it takes on all real numbers so you have that part right.

The relation is a function because it passes the vertical line test. (I can' see your is it a function part or not)

y = 2x+5 has y-intercept 5 and slope 2. The domain is the values of x that relation takes on, it takes on all real numbers so you have that part right.

The range of values that we are permitted to enter into our function is known as the domain of a function.

The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

The range is the values of y that relation takes on, it takes on all real numbers from ( -2.5,0) to ( 0, 5 ).

The relation is a function because it passes the vertical line test.

Therefore, y = 2x+5 has y-intercept 5 and slope 2. The domain is the values of x that relation takes on, it takes on all real numbers so you have that part right.

Answer:

The regression line fits the data well. Problem can be when there is a trend, like exponential growth, but someone still wants to use linear regression. Although in this case it seems to be okay. In other words, the data points can be found under or over the line randomly. In a problematic case is when for example, there are 5 data points next to each other under the line. Usually companies don't make profit when they're first starting.

First  I focused on 3 or more points that were collinear to each other.  Collinear means that when you connect these points, you get a straight line.  These points are at months 1, 2, 3, and 9.  Then of these points, I chose 2 points to find the slope between them.

Point 1 = (1, 0)

Point 2 = (2, 2.5) or  (2, 2500)         because profit is measured in thousands

These are the first two points.

Slope = (2500 - 0) / (2 - 1)

Slope = 2500 / 1

Slope = 2500

Then I plug in the slope and values of point 1 into the slope-intercept form of the line.

y = mx + b

0 = 2500(1) + b

Now we have to Solve for b.

0 = 2500 + b

-2500 = b

Plug in this value of b into the slope intercept form of the equation to get the best fit line.

 y = 2500x - 2500

Answer:

i agree with the guy above

Step-by-step explanation:

Answer:

No, since the slopes are different

Step-by-step explanation:

Parallel lines by definition have the same slope but different y-intercepts. The slope of the line  y = 6x + 9 is 6, the coefficient of x since the equation is given in slope-intercept form. Its y-intercept is 9.

For the second equation, 27x – 3y = –81 , we have to solve for y or re-write the equation in slope-intercept form;

-3y = -27x - 81

y = 9x + 27

The slope of this line is thus 9, the coefficient of x since the equation is in slope-intercept form. Its y-intercept is 27.

The two equations have different slopes and thus they are not parallel

Answer:

∠3 = 62°

Step-by-step explanation:

The diagonals of a kite are at right angles to each other, hence

Triangle containing ∠ 3 is a right triangle

The sum of the 3 angles in a triangle = 180°, thus

90 + 28 +∠3 = 180

118 + ∠3 = 180 ( subtract 118 from both sides )

∠3 = 62°

Answer:

Final price = 1.06x

Step-by-step explanation:

If a city has a 6% general sales tax, then the total cost of any purchase will be the original price of an item plus 6%, as follows:

Final price = (x + 0.06x) = 1.06x

Therefore, the total cost of any purchase is 1.06 where 'x' represents the price of the items without taxes.

Answer:

Step-by-step explanation:

Let's say the circulation for newspaper 1 is X. Then the circulation for newspaper 2 is smaller, by 382, so we can call it (X - 382). It's really 382,000 of course, but we can leave off the extra zeros for now.

Anyway, the total of both would have to be X + (X - 382) = 2492. This simplifies to:

2X - 382 = 2492

If you can solve that equation, you'll have the circulation for newspaper 1, in thousands.

Does this give you a push in the right direction?

The circulation of newspaper 1 is 1437 thousand and the circulation of newspaper 2 is 1055 thousand.

This question requires us to use a system of linear equations to solve for the circulation for each newspaper. Let's denote the circulation of newspaper 1 as x and the circulation of newspaper 2 as y.

We have two pieces of information that help us form two separate equations. The first piece of information is that newspaper 1's circulation is 382 thousand more than newspaper 2's circulation, so we can express this as:

x = y + 382

The second piece of information is that the combined circulation of both newspapers is 2492 thousand. Therefore, we form the equation:

x + y = 2492

We can now replace x in the second equation with the value of x from the first equation (y + 382) to solve for y:

(y + 382) + y = 2492

Solving that, we find that y (the circulation of newspaper 2) is 1055 thousand. Substituting y into the first equation, we can solve for x (the circulation of newspaper 1), which is 1437 thousand.

Answer:

144.5cm^2

Step-by-step explanation:

First find area of the rectangle

Area of a rectangle = L*B

= 9*13 = 117cm^2

Now find area of the triangle

Area of triangle. = 1/2 base * height

Height = 13 - 8 =5cm

Area of the triangle = 1/2 *11 *5 = 27.4

Now area of the who figure is area of rectangle + area of triangle

= 117 + 27.5

= 144.5cm^2

For this case we have that the area of the figure is given by the area of a rectangle plus the area of a triangle.

The area of a rectangle is given by:

[tex]A = a * b[/tex]

Where a and b are the sides of the rectangle.

According to the figure we have:

[tex]a = 13 \ cm\\b = 9 \ cm[/tex]

So, the area of the rectangle is:

[tex]A = 13 * 9\\A = 117 \ cm ^ 2[/tex]

On the other hand, the area of a triangle is given by:

[tex]A = \frac {1} {2} b * h[/tex]

Where b is the base of the triangle and h the height. According to the figure we have:

[tex]b = 13-8 = 5 \ cm\\h = 11 \ cm[/tex]

Substituting:

[tex]A = \frac {1} {2} 5 * 11\\A = 27.5 \ cm ^ 2[/tex]

Adding up we have the total area is:

[tex]A_ {t} = 117 \ cm ^ 2 + 27.5 \ cm ^ 2\\A_ {t} = 144.5 \ cm ^ 2[/tex]

Answer:

Option B

Answer:

54

Step-by-step explanation:

3 tens = 3*10 = 30

24 ones = 24*1 = 24

30+24 = 54

Final answer:

The number that represents 3 tens + 24 ones is 54. This is found by adding 30 (representing the 3 tens) to 24 (representing the 24 ones).

Explanation:

The number that is the same as 3 tens + 24 ones is calculated by first understanding what each term represents.

Three tens is equivalent to 30 because one ten equals 10 and 10 multiplied by 3 equals 30.

Twenty-four ones simply means 24 because one multiplied by 24 is 24.

Therefore, to find the number that represents 3 tens + 24 ones, we add 30 and 24 together.

30 (3 tens) + 24 (24 ones) = 54

So, the number that is the same as 3 tens + 24 ones is 54.

Answer:

The cost of one bucket of popcorn is $2.75

The cost of one drink is $1.25

Step-by-step explanation:

Let

x ----> the cost of one bucket of popcorn

y ----> the cost of one drink

we know that

5x+2y=16.25 -----> equation A

3x+y=9.50

y=9.50-3x ----> equation B

Solve the system of equations by substitution

Substitute equation B in equation A and solve for x

5x+2(9.50-3x)=16.25

5x+19-6x=16.25

6x-5x=19-16.25

x=$2.75

Find the value of y

y=9.50-3x

y=9.50-3(2.75)=$1.25

therefore

The cost of one bucket of popcorn is $2.75

The cost of one drink is $1.25
