Answer:

The best prediction will be B) 35

Step-by-step explanation:

By looking at the scatterplot ,

we can see that it the City MPG vs Highway MPG approximately falls on a straight line.

we can either find the slope of it ( which might be a little out of syllabus ) or we can extend the line connecting the maximum number of points.

When we do so, We get a line as attached in the diagram.

And we extend it.

From the graph attached we find that the value of City MPG falls somewhere in between the lines of 30 and 35 ( though this is just and approximation).

thus the more appropriate answer would be : 35

Answer:

x<-8

Step-by-step explanation:

four more than twice a number = 4+2X

is less than negative twelve = <-12

4+2X<-12

(4-4)+2X< -12-4

2x<-16

X<-8

To find the numbers that make the statement true, we need to solve the equation 2x + 4 < -12 for x. Any number less than -8 will make the statement true.

To find the numbers that make the statement true, we need to translate the given sentence into a mathematical equation. Let's denote the unknown number as 'x'. The sentence 'Four more than twice a number is less than negative twelve' can be written as 2x + 4 < -12. Now, we can solve this equation for x:

Subtracting 4 from both sides, we get 2x < -16.

Dividing both sides by 2, we have x < -8.

Therefore, any number less than -8 will make the statement true.

Answer:

12:30PM

Step-by-step explanation:

Known information:

There are 4 classes.

Each class is 1 hour.

There are 10 minutes between classes, like a break.

Draw a diagram:

start-CLASS1, break, CLASS2, break, CLASS3, break, CLASS4-end

There are 3 breaks because there are no breaks before and after the first  and last classes.

Multiply the number of classes by the time length for class.

Multiply the number of breaks by the time length for breaks.

Add the two numbers together to get the total school time:

Classes: 4*1h = 4h

Breaks: 3*10min = 30min

4h + 30min = 4h 30min

Calculate 4h and 30min after 8:00 AM.

Add 4 hours and 30 minutes to 8.

.    8:00

+   4:30

.    12:30

In the AM/PM clock (not 24 hour clock) there are 12 hours. After 12:59, it becomes 1:00, not 13:00.

Since "12:30" is possible on the AM/PM, we do not need to fix it.

The AM/PM clock changes at 12:00.

This means that after 11:59PM it becomes 12:00AM.

After 11:59AM it becomes 12:00PM.  (Usually lunch)

Since 12:30 passed 11:59, the AM/PM sign changes.

The fourth class ends at 12:30PM.

The kinetic energy (Ek) of the car with a mass of 1000 kg moving at a speed of 20 m/s is calculated using the formula Ek = 0.5 * m * v². Substituting the given values, we find the kinetic energy to be 2.00 x 10⁵ Joules.

To calculate the kinetic energy (Ek) of a car with a given mass and speed, you can use the formula Ek = 0.5 * m * v², where m is the mass, and v is the speed. In this case, the mass (m) of the car is 1000 kg, and the velocity (v) is 20 m/s.

Substituting the given values into the formula, we have Ek = 0.5 * (1000 kg) * (20 m/s)². This simplifies to Ek = 2.00 x 10⁵ J (Joules), which is the kinetic energy of the car.

It's important to note that kinetic energy always has units of Joules in the International System (or SI), and it represents the energy that an object has due to its motion.

Answer: Y=-1 or Y=-1+4

Step-by-step explanation:

To find the equation of a line parallel to the given line and passing through a specific point, we can use the point-slope form of a linear equation.

To find the equation of a line that is parallel to the given line and passes through the point (3, 1), we need to use the fact that parallel lines have the same slope. Since the given line has a slope of 4, the parallel line will also have a slope of 4. Using the point-slope form of a linear equation, we can write the equation as:

y - y1 = m(x - x1)

Plugging in the values from the given point (3, 1) and the slope (4), we get:

y - 1 = 4(x - 3)

Simplifying the equation, we have:

y - 1 = 4x - 12

y = 4x - 11

Therefore, the equation of the line that is parallel to the given line and passes through the point (3, 1) is y = 4x - 11.

Answer:

The correct answer is D. 414 in squared.

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

Area of the first circle = 11.5 inches ²

2. Let's calculate the area of the new circle, given that the radius of the first circle is multiplied by 6.

Area of the first circle = 11.5 inches ²

Let's find the radius:

π * r² = 11.5

r² = 11.5 / 3.1416

r² = 3.66055513

r = 1.91 inches

The first circle has a radius of 1.91 inches

So, the radius of the second circle is 1.91 * 6 = 11.48 inches

Area of the second circle = π * r²

Area of the second circle = 3.1416 * 11.48²

Area of the second circle = 3.1416 * 131.79

Area of the second circle = 414.03 inches ²

Area of the second circle = 414 inches ² (Rounded to the nearest whole number)

The correct answer is D. 414 in squared.

To find the perimeter of the bedroom floor, subtract the rug's length and width from the floor's length and width. Then, use the formula 2(length + width) to calculate the perimeter. The perimeter of the bedroom floor is 64 ft.

To find the perimeter of the bedroom floor, we need to subtract the length and width of the rug from the length and width of the floor. The length of the floor is 10 ft and the rug leaves 1 ft exposed on each side, so the length of the rug is 8 ft. Similarly, the width of the floor is 8 ft and the rug leaves 1 ft exposed on each side, so the width of the rug is 6 ft. Therefore, the perimeter of the bedroom floor is 2(10 ft + 8 ft) + 2(8 ft + 6 ft) = 2(18 ft) + 2(14 ft) = 36 ft + 28 ft = 64 ft.

Answer:

FG = 47

Step-by-step explanation:

The opposite sides of a parallelogram are parallel and congruent, thus

EH = FG, that is

5z - 18 = 3z + 8 ( subtract 3z from both sides )

2z - 18 = 8 ( add 18 to both sides )

2z = 26 ( divide both sides by 2 )

z = 13

Hence

FG = 3z + 8 = (3 × 13) + 8 = 39 + 8 = 47

Based on the property of a parallelogram, the measure of FG is: 47.

Based on the properties of a parallelogram, the opposite sides of a parallelogram are equal in length.

Therefore:

EH = FG

5z - 18 = 3z + 8

5z - 3z = 18 + 8

2z = 26

z = 13

FG = 3z + 8

FG = 3(13) + 8

Answer:

(x + 2)² + (y + 5)² = 25

Step-by-step explanation:

The circle is tangent to the x-axis at (-2, 0).  This means the center of the circle must be directly above or below this point.  So the x-coordinate of the center is -2.

Since the center of the circle is on the line y = 3x + 1, we can find the y-coordinate:

y = 3(-2) + 1

y = -5

The center of the circle is (-2, -5).  The distance between the center and the point (-2, 0) is 5 units.  This is the radius of the circle.

We can now write the equation of the circle:

(x − h)² + (y − k)² = r²

(x + 2)² + (y + 5)² = 25

Graph:

desmos.com/calculator/wzionolfli

Th equation of the circle will be (x + 2)² + (y + 5)² = 25.

A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point.

At, the circle is perpendicular to the x-axis (-2, 0). Therefore, the circle's centre must be located directly above or below this point. Therefore, the centre's x-coordinate is -2.

We can determine the y-coordinate because the circle's centre lies on the line y = 3x + 1:

y = 3(-2) + 1

y = -5

The circle's nucleus is (-2, -5). The centre is located 5 units away from the point (-2, 0). This is the circle's radius.

We can now write the equation of the circle:

(x − h)² + (y − k)² = r²

(x + 2)² + (y + 5)² = 25

Therefore, the equation of the circle will be (x + 2)² + (y + 5)² = 25.

A). f(x) = (-5)x + 90

Step-by-step explanation:

A). As shown in the graph, line of best fit is passing through two points (0, 90) and (18, 0).

Equation of this line will be in the form of y = mx + b.

Here m = slope of the line

b = y-intercept

Since slope of a line passing through two points (x, y) and (x', y') is represented by,

m = [tex]\frac{y-y'}{x-x'}[/tex]

So slope of the line of best fit from the given graph,

'm' = [tex]\frac{90-0}{0-18}[/tex]

m = (-5)

y-intercept 'b' = 90

When we plug in these values in the equation,

y = (-5)x + 90

Function representing this situation,

f(x) = -5x + 90

B). Slope of the line of best fit shows the change in sales per day in the month of Feb that is "5 golf carts per day".

Answer:

30 miles

Step-by-step explanation:

We know

D = RT

Where

D is the distance

R is the rate

T is the time

Towards Island:

R = 15

Let time be x

So, we can write:

D = 15x

Return from Island:

R = 10

Let time be y

So, we can write:

D = 10y

Also, total time is 5 hours, so we can write:

x + y = 5   [equation 2]

Now, since the distance for both legs of the journey is equal, we can write:

Distance 1 = Distance 2

15x = 10y

Now we replace this equation with equation 2, so we get:

Equation 2: x + y = 5 or x = 5 - y

15x = 10y

15(5 - y) = 10y

75 - 15y = 10y

75 = 25y

y = 75/25

y = 3

Distance 2 = D = 10y

Replacing y with 3, we get:

D = 10y

D = 10(3)

D = 30

So, the distance to island is 30 miles
