What’s the slope of the graph?

The y-intercept and slope of the line described by these points will be y = (1/4)x + 5.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂). Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

Taking only two points from the table will be (4, 6) and (12, 8). Then the equation of the line is given as,

(y - 6) = [(8 - 6) / (12 - 4)](x - 4)

y - 6 = 1/4(x - 4)

y - 6 = (1/4) x - 1

y = (1/4)x + 5

The y-intercept and slope of the line described by these points will be y = (1/4)x + 5.

Answer:

y = 26 I think lol

Step-by-step explanation:

2(3y + 7 + 5) = 196 - 16

196 - 16= 180

2(3y + 7 + 5) = 180

6y + 14 + 10 = 180

6y + 24 = 180

6y = 180 - 24 = 156

6y = 156

y = 156 divided by 5

y= 26

Answer:

O 81 km per hour

Explanation

Given parameters:

Number of days traveled  = 3 days

Distance covered on the first day  = 1080km

Time of travel  = 10hrs

Rate of travel  = 108km/hr

Time of travel on second day = 12hrs

Rate of travel  = 90km/hr

Time of travel on third day  = 18hrs

Rate of travel  = 60km/hr

Unknown

Average speed  = ?

To find the average speed, we sum the distances and divide by the sum of the time.

  Average speed  = [tex]\frac{Total distance}{total time}[/tex]

we do not know the second and third distances;

  Distance  = speed x time

D2  = 90 x 12 = 1080km

D3  = 60 x 18  = 1080km

    Now;

  Average speed  = [tex]\frac{1080 + 1080 + 1080 }{10 + 12 + 18 }[/tex]

 Average speed  = [tex]\frac{3240}{40}[/tex]   = 81km/hr

The average speed is 81km/hr

Answer:

a

 center is  0.275

 [tex]SE = 0.063[/tex]

b

 center is  0.275

 [tex]SE = 0.020[/tex]

Step-by-step explanation:

considering question a

From the question we are told that

   The sample size is  n  =  50

 The proportion of  US adults are college graduates is  p = 0.275

Generally the center is equivalent to the proportion so the center is  0.275

Generally the standard error is  

      [tex]SE =  \sqrt{\frac{p *  (1- p)}{ n} }[/tex]

=>   [tex]SE =  \sqrt{\frac{0.275 *  (1- 0.275)}{ 50} }[/tex]

=>   [tex]SE = 0.063[/tex]

considering question b

    The sample size is  n  =  500

      The proportion of  US adults are college graduates is  p = 0.275

     Generally the center is equivalent to the proportion so the center is  0.275

     Generally the standard error is  

      [tex]SE =  \sqrt{\frac{p *  (1- p)}{ n} }[/tex]

=>   [tex]SE =  \sqrt{\frac{0.275 *  (1- 0.275)}{ 500} }[/tex]

=>   [tex]SE = 0.020[/tex]

In the sampling distribution, the center of the sampling distribution is 0.275 and the standard error is 0.063.

A sampling distribution simply means the probability distribution that is gotten from a larger number of samples that are drawn from a population.

In this case, the center of the sampling distribution is 0.275 and the standard error is 0.063. The standard error will be:

= [p × (1 - p)]/n

= [0.275 × (1 - 0.275)]/50

= 0.0039875

= ✓0.0039875

= 0.063

Also, when the sample is 500, the center of the sampling distribution is 0.275 and the standard error is 0.020.

Step-by-step explanation:

The side length of perry's phone will be 8 inches.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is Perry who wants to project a movie from his phone to a screen on the wall. The side length of the screen is 56 in. The scale from the screen to the phone is 7 in. to 1 in.

Assume the side length of perry's phone be [x] inches. Then, we can write the proportion as -

56/x = 7/1

x = 56/7

x = 8

Therefore, the side length of perry's phone will be 8 inches.

They scored either 8 or 9 goals in second game.

Combining things and counting them as one big group is done through addition. In math, addition is the process of adding two or more integers together. Addends are the numbers that are added, while the total refers to the outcome of the operation.

As, Total goals = 10 in two games

Let x be the number of goals that a soccer team scored in the first half

and, y be the number of goals that a soccer team scored in the second half

So, x+ y = 10

x= 2 and y = 8

Thus, 2+ 8 = 10

Hence, They scored either 8 or 9 goals in second game.

Answer:

36300

Step-by-step explanation:

Answer:

The answer is 36,300.

Step-by-step explanation:

Okay, here's what we know, Jon has 60,500 cars and 60% of those cars are green. And what we are trying to figure out is how many cars are green.

So we need to convert the problem to an equation using the percentage formula: P% * C = G.

P stands for the percentage, C stands for the total number of cars, and G stands for the total number of green cars.

1. The percentage of green cars is 60% of all the cars. The variable C is 60,500, so the equation is 60% * 60,500 = G.

2. Convert 60% to a decimal by removing the percent sign and dividing by 100: 60/100 = 0.6.

3. Substitute 0.6 for 0.6% in the equation: 60% * 60,500 = G.

4. G becomes 0.6.

5. Do the math: 0.6 * 60,500 = 36,300.

6. G = 36,300.

So 60% of 60,500 is 36,300 and 36,300 cars are green

Let's double check our answer with the original question: What is 60% of 60,500?

Multiply 0.6 * 60,500 = 36,300

So yes, our answer is correct and Jon has 36,300 green cars.

Answer:

a. N(t) = 1.25 (1/2)^t/7

b. 0.1160933038mg.

Step-by-step explanation:

The formula for half life =

N(t) = No(1/2)^t/t½

Where N(t) = Amount of Substance left

No = Initial amount not Substance

t = time after t years

t½ = Half life of the substance

From the question:

No = 1.25mg

t½ = 7 years

a. Find a model for the amount of albuterol left in the body t hours after an initial dose of 1.25 mg.

N(t) = No(1/2)^t/t½

No = 1.25mg

t½ = 7 years

N(t) = 1.25 (1/2)^t/7

b. How much albuterol is left in the body after 24 hours?

Using the model in the above question

N(t) = 1.25 (1/2)^t/7

N(t) = 1.25(1/2)^24/7

N(t) = 1.25(0.5)^3.4285714286

N(t) = 0.1160933038mg

Therefore, the quantity of albuterol left in the body after 24 hours is 0.1160933038mg.
