Jon has 60,500 cars. He is a car dealer. 60% of the cars are green. How many cars are green?

Answers

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.

The slope of the LlNE 1 is negativeFor the vertical line, since the line is parallel to the y axis and the change in the x-value is zero, hence the slope of LINE  2 will be UNDEFINEDThe slope of LlNE 3 is positiveFor the horizontal line (fourth graph), since the line is parallel to the x-axis and the change in the y-value is zero, hence the slope of LINE  4 will be ZERO

The slope of a line is determined by its steepness.

The formula for calculating slope is expressed as;

[tex]\frac{\triangle y}{\triangle x} = \frac{y_2-y_1}{x_2-x_1}[/tex]

For the first graph, we can assume the coordinates (-1, 0) and (0, -2), the [tex]\frac{\triangle y}{\triangle x} = \frac{-2-0_1}{0-(-1)}\\\frac{\triangle y}{\triangle x} = \frac{-2}{1}\\\frac{\triangle y}{\triangle x} = -2\\\\[/tex]

Since the slope is -2 which is a negative value, hence the slope of LlNE 1 is negative

For the vertical line, since the line is parallel to the y axis and the change in the x-value is zero, hence the slope of  LINE  2 will be UNDEFINED

For the THIRD graph, we can assume the coordinates (2, 0) and (0, -2), the [tex]\frac{\triangle y}{\triangle x} = \frac{-2-0}{0-2}\\\frac{\triangle y}{\triangle x} = \frac{-2}{-2}\\\frac{\triangle y}{\triangle x} = 1\\\\[/tex]

Since the slope is 1 which is a negative value, hence the slope of LlNE 3 is positive

For the horizontal line (fourth graph), since the line is parallel to the x-axis and the change in the y-value is zero, hence the slope of LINE  4 will be ZERO

It is known that Ray AP bisects angle CAT. If m<CAT = 5x+17 and m<PAT = 3x-4, then determine the value of x.​

Answers

Answer:

x = 25

Step-by-step explanation:

It is given that, ray Ray AP bisects angle CAT. It means,

[tex]\angle CAT=\angle CAP+\angle PAT[/tex]

Also, [tex]\angle CAP = \angle PAT[/tex]

It gives, [tex]\angle CAT=2\angle PAT[/tex]

ATQ,

[tex]\angle CAT = 5x+17 \ \text{and}\ \text{PAT}=3x-4[/tex]

So,

[tex]5x+17=2(3x-4)\\\\5x+17=6x-8[/tex]

Taking like terms together,

[tex]5x-6x=-8-17\\\\-x=-25\\\\x=25[/tex]

So, the value of x is 25.

An appliance manufacturer claims to have developed a new toaster oven that consumes an average of no more than 250 W. From previous studies, it is believed that power consumption for toaster ovens is normally distributed with a standard deviation of 18 W. A consumer group suspects the actual average is more than 250 W. They take a sample of 16 toaster ovens and calculate the average consumption to be 260 W. Answer the following questions:

a. Would you reject the Null at 1% level of significance?
b. Would you say the toaster oven consumes more than 250 W of power if you are willing to commit a Type 1 Error of 2.5%?
c. What is the cut-off Watts at 2.5% level of significance?
d. In reality, suppose the average power consumption is 265 W. What is the Type II error when Type I error is set at 2.5%?
e. What is the cut-off Watts at 1% level of significance?
f. In reality, suppose the average power consumption is 265 W. What is the Type II error when Type I error is set at 1%?
g. Based on these calculations, what happens to Type II error if Type I error is lowered?
h. Based on these calculations, what happens to Type I error if Type II error is increased?


Answers

Answer:

a. No the null hypothesis cannot be rejected at  1% level of significance as the calculated value of z= 2.222 which lies with in 2.333

b. Yes for the  Type 1 Error of 2.5% we say the toaster oven consumes more than 250 W of power because the calculated value 2.22 lies outside the region for 1.96

c. The cut-off at 2.5% level of significance is 258.82 W.

d. 0.85 is the area for Type 2 error.

e. The cut-off at 1% level of significance is 260.485W.

f.  0.154 is the area for Type 2 Error

What is informal proof?

Informal proofs are used to proof a theorem in different methods of  proving theorems and steps of the proof are not formally framed.

Mostly by taking a particular example a theorem is proved.

All square are similar.

This statement is true

Option 1 is false

Option 2 is formal proof as sides of squares A and B are taken as variables x and y therefore this proof can be used for any pair of two squares

Option 3. is wrong proof as the  two sides of square A and B are taken unequal but square has all four sides equal.

Option 4 is correct proof but it is not a formal one as a particular example is taken to proof with statement

Therefore option 4 is the correct option that show the informal proof of the given statement.

The ratio of the change in the y and x values, in the table gives the slope

graph of the linear function.

Correct response:

The slope of the linear function is -6

What is slope?

The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as, dx/dy.

here, we have,

Method used for finding the slope

From the given table, we have;

The first difference of the y-values = 2 - 8 = -6 = Constant

The rate of change of the x-values = 1 = Constant

Therefore;

The function is a linear function;

The slope, m, is given by the formula;

m = y2 - y1/x2-x1

Taking a pair of points as follows;

(0, -4) = (x₁, y₁)

(2, -16) = (x₂, y₂)

We have;

m = -6

The slope of the linear function, m = -6

average speed.
O 81 km per hour
O 80km per hour
O 83 km per hour
82 km per hour​

Answers

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

Truckco manufactures two types of trucks: 1 and 2. Each truck must go through the painting shop and assembly shop. If the painting shop were completely devoted to painting Type 1 trucks, then 800 per day could be painted; if the painting shop were completely devoted to painting Type 2 trucks, then 700 per day could be painted. If the assembly shop were completely devoted to assembling truck 1 engines, then 1,500 per day could be assembled; if the assembly shop were completely devoted to assembling truck 2 engines, then 1,200 per day could be assembled. Each Type 1 truck contributes $300 to profit; each Type 2 truck contributes $500. formulate an LP that will maximize Truckco’s profit.

Answers

Answer:

Step-by-step explanation:

Let y represent type 2 truck and x represent type 1 truck. The painting can be represented by the inequality:

[tex]\frac{x}{800}+\frac{y}{700}\leq 1[/tex]                  (1)

The assembling can be represented by the inequality:

[tex]\frac{x}{1500}+\frac{y}{1200} \leq 1[/tex]                (2)

Also, x, y ≥ 0

The objective function is given as:

max z = 300x + 500y

Plotting 1 and 2 using online geogebra

From the graph, the optimal value is at (0,700). Hence:

max z = 300(0) + 500(700) = $350000
