A school principal plans to form teams from 126 third-graders, 180 fourth-graders, and 198 fifth-graders so that there is the same number of students from each grade level on each team. If all students participate, what is the largest possible number of teams and how many students will there be on each team?

Answers

Answer:

There are 9 teams possible each having 14 third-graders, 20 Fourth-graders, 22 Fifth-graders

Step-by-step explanation:

126 third-graders

180 fourth-graders

198 fifth-graders

Find the highest common factor of 126, 180, 198

Factors of 126: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126.

Factors of 180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

Factors of 198: 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198.

The highest common factor of 126, 180, 198 is 9

The largest possible number of teams that can be formed is 9

Each team has

third-graders = 126 / 9

= 14

Fourth-graders = 180 / 9

= 20

Fifth-graders = 198 divided by 9

= 22

There are 9 teams possible each having 14 third-graders, 20 Fourth-graders, 22 Fifth-graders

A federal government agency that is responsible for setting vehicle fuel economy standards for automobile manufacturers is conducting research in order to update its fuel economy standards for the year 2030. Automobile​ manufacturers, and​ consumers, are highly interested in what the​ agency's findings and determinations will be as this will affect every vehicle in the United States. The federal government agency is very interested in the relationship between the weight of a vehicle and the​ vehicle's fuel economy​(average miles per gallon​ (MPG)). Specifically, the agency is concerned that if the current trend of automobile manufacturers producing heavier new vehicles continues that its fuel economy targets will not be met. The​ agency's research department recently collected data for analysis in order to support the​ agency's upcoming discussion with industry regarding its proposed 2030 fuel economy standards. The average MPG from a random sample of 750 vehicles was recently calculated by the agency. The research division also collected the vehicle weight of these 750 randomly sampled vehicles. The Vehicle​ Number, Type, Vehicle​ Weight, Average​ MPG, Fuel Tank Size​ (Gallons), Engine Size​ (Liters), and Meet or Not Meet Current Standards data were collected for these 750 vehicles.
Which of the following most closely describes the method of data collection​ used?
a. Anecdote
b. Controlled experiment
c. Observational study

Answers

Answer:

Controlled experiment

The method of data collection used by the federal government agency is controlled experiment.

What is Controlled Experiment?

A controlled experiment can be defined as an experiment under which an independent variable is constantly manipulated in order to evaluate its effects on other dependent variables.

The experiment conducted on 750 vehicles by federal government agency to determine the relationship between weight of the vehicle and its fuel economy  is a controlled experiment since the effects of weight of vehicles is observed on their fuel economy, other things remaining constant.

The fuel economy changes with the change in weight of the vehicle. The vehicle weight therefore affects the fuel economy or average MPG of the vehicle.

Therefore the method of data collection used is controlled experiment.

Answers

Answer:

6. Ethan should shade the region marked B

7. No, point (0, 4) will not be included in the solution set

8. Point (0, -2) will not be included in the solution set

Step-by-step explanation:

Let us explain how to solve the question

The graph represents the equation 2x - 5y = 10

The inequality is 2x - 5y > 10

The sign of inequality is greater than without equal, that means the line represents it must be a dotted line because all the points on the line do not belong to the solution set of the inequality.

To find the area of the solution you must put y on a side and the other term on the other side

∵ 2x - 5y > 10

→ Add 5y to both sides to move y in the other side

∴ 2x - 5y + 5y > 10 + 5y

∴ 2x > 10 + 5y

→ Subtract 10 from both sides to move 10 to the other side

∵ 2x - 10 > 10 - 10 + 5y

∴ 2x - 10 > 5y

→ That means 5y < 2x - 10

5y < 2x - 10

6.

→ y < that means the area of the solutions is under the line

∴ The solutions of the inequality lie in area B

Ethan should shade the region marked B

7.

∵ Point (0, 4) lies above the line in the region marked A

→ That means it does not lie in the area of the solutions

Point (0, 4) will not be included in the solution set

8.

∵ Point (0, -2) lies on the line

∵ All the point on the line did not belong to the solution set as we

  said before

Point (0, -2) will not be included in the solution set

0.25 is the answer which is the same as 1/4 just as a decimal

The solution of the equation 3g + 5 = 7g + 4 will be 1/4.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The equation is given below.

3g + 5 = 7g + 4

Simplify the equation, then we have

3g + 5 = 7g + 4

- 7g + 3g = 4 - 5

- 4g = - 1

g = (-1) / (-4)

g = 1 / 4

The solution of the equation 3g + 5 = 7g + 4 will be 1/4.

Answers

Answer:

y = 1/4x + 17/4

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Perpendicular lines have the negative reciprocal slope.

m = 1/4

y = 1/4x + b

4 = 1/4(-1) + b

4 = -1/4 + b

17/4 = b

The number of ferryboat trips f(c), needed to transport c cars in 1 day can be found using the function f(c) = c/20 To transport the maximum 1000 cars, the ferry makes 125 daily trips, What is the range of the function?

Answers

Answer:

F(C)<250

Step-by-step explanation:

To solve the problem we need to remember that a function is a relationship between an input usually called "x" (domain) and an output, usually called "y" and it's also the range of the function.

F(X)=y

We are given a relationship (a function) between the ferryboat trips "c" and the number of cars transported per day.

f(C)=C/20

Hence, the range of the function knowing that there are not more than 5000 cars transported by the ferryboat (daily) the range is all the numbers that are less or equal to 250.

F(C)<250

Answer: x = 13

Step-by-step explanation:

They are equal so set them equal and solve for x.

(4x+1) = 53

4x = 52

x = 13

Answer:

Since the lines l and m are parallel,

angle (4x + 1) and angle 53 are both corresponding angles

We know that corresponding angles are equal, so:

4x + 1 = 53

4x = 52

what is the new equation written in slope-intercept form y=mx+b​

Answers

Answer:

m= -2

b= 2

y= -2x + 2

Step-by-step explanation:

Just did it

The slope of a line is m = -2 that passes through the points (-3, 8) and (4.-6), the y-intercept (b) of the line is 2, and the equation is y = -2x + 2.

What is the slope of the line?

The slope of a line is defined as the gradient of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Given that the line that passes through the points (-3, 8) and (4.-6).

Let

x₁ = -3, y₁ = 8

x₂ = 4, y₂ = -6

∵ Slope m = (y₂ - y₁)/(x₂ -x₁  )

Substitute values in the formula

m = (-6 - 8)/(4 -(-3))

m = (-14)/7

m = -2

y - 8 = m(x - (-3))

y - 8 = -2(x + 3)

y = -2x -6 + 8

y = -2x + 2

Since the slope-intercept form, y = mx+b

So the y-intercept (b) of the line,

b = 2

Thus, the slope of a line is m = -2 that passes through the points (-3, 8) and (4.-6), the y-intercept (b) of the line is 2, and the equation is y = -2x + 2.
