There are 6,840 ways to award the prizes to the first three cars completing the race.

Since there are 20 cars within the race and the arrangement in which they wrap up is critical, a permutation equation can be utilized to decide the number of ways prizes are granted.

 There are his 20 ways to determine the winner of the first prize (because any of the 20 cars could be first).

He has 19 ways to determine the runner-up (because he has 19 cars left to be runner-up).

There are 18 ways to determine the 3rd place winner (because he has 18 cars left that could be 3rd place).

Using the multiplication principle, the total number of ways to award prizes is:

20 x 19 x 18 = 6,840

So there are 6,840 ways to award prizes to the top 3 cars that finish the race.

Answer:

First, we need to find the radius of the cylinder. We know that:

V = πr^2h

And we are given that V = 1,130.97 cubic inches. We also know that a cylinder is symmetrical, which means that the height of the cylinder is equal to the diameter of the circle. In other words, h = 2r.

Therefore, we can rewrite the formula as:

V = πr^2(2r)

1,130.97 = πr^3

r^3 = 359.82

r = 7.12 inches (rounded to two decimal places)

Now we need to find the amount of space on either side of the cylinder. We know that the pedestal is 18 inches across, so the total width is 18 inches. If we want an even amount of space on either side, we need to subtract the diameter of the cylinder from the width of the pedestal, and then divide the result by two.

Diameter = 2r = 2(7.12) = 14.24 inches

Space on either side = (18 - 14.24)/2 = 1.88 inches (rounded to two decimal places)

Therefore, if Consuela places the cylinder on a pedestal that is 18 inches across, there will be 1.88 inches of space on either side.

Based on the survey data, we can conclude that a higher proportion of teenagers own an iPod or MP3 player compared to young adults.

To determine if the difference is significant, we need to conduct a hypothesis test. We can begin by stating the null hypothesis as "there is no significant difference in the proportion of all teens and young adults who would say they own an iPod or MP3 player."

We can also state the alternative hypothesis as "there is a significant difference in the proportion of all teens and young adults who would say they own an iPod or MP3 player."

Next, we need to determine the test statistic and calculate the p-value to determine if the difference in the proportions is statistically significant. Assuming that the data follows a normal distribution, we can use a two-sample z-test to test our hypothesis.

Using a significance level of 0.05, we find that the test statistic is 3.07, and the p-value is 0.002. Since the p-value is less than the significance level, we can reject the null hypothesis and conclude that there is convincing evidence of a difference in the proportions of all teens and young adults who would say they own an iPod or MP3 player.

In a series circuit, charges follow a single path, meaning that they flow through each component of the circuit one after another.

What is series circuit?

A series circuit is an electric circuit in which the components (such as resistors, capacitors, and inductors) are connected in a single path so that the current flows through each component in turn without branching off.

In a series circuit, charges follow a single path, meaning that they flow through each component of the circuit one after another. This means that the current passing through each component is the same, and the voltage is split between the components. If one component fails, the circuit is broken, and no current can flow.

In contrast, in a parallel circuit, charges have multiple paths to flow through. The current splits up and passes through each path independently, meaning that the current through each component is not necessarily the same.

The voltage across each component is the same, and the total current is the sum of the current through each path. If one component fails, the current can still flow through the other paths, and the circuit remains complete.

Answer:

y-intercept = (0,0)

x-intercepts (0,0), (-2, 0)

Step-by-step explanation:

For y-intercept

If you think about a graph, when does the graph intercept/hit y.   What is your value for x.   Your y-intercept is usually (0, y)   So in order to find the y-intercept you need to plug in x=0 to find y.

Equation:

y=16x²+32x       substitute x=0

y=16(0)²+32(0)

y=0

y-intercept = (0,0)

For x-intercept

When you have an x intercept it looks like (x, 0), so you must solve for x when y=0

Because this is a quadratic equation(parabola), you will get 2 x-intercepts.

y=16x²+32x

0=16x²+32x      > In order to solver for x, you must factor but in this case

                            you can take out the greatest common factor (GCF) =16x

0=16x(x +2)       >Typically when you factor you get 2 parentheses and set

                            each parenthesis equal to 0, but instead we've pulled

                            an x on the outside.  When there is an x outside you set

                            the outside equal to 0 as well as the parenthesis to

                            solve for x.

16x = 0                 (x+2)=0

x=0                           x= -2

Answer:

Dear Kindergarten students,

Today, I am here to talk to you about place value and why it is important. Place value is the concept of understanding the value of a digit based on its position in a number. In other words, the position of a digit determines its value.

Let's take the number 123 for example. The digit 1 is in the hundreds place, the digit 2 is in the tens place, and the digit 3 is in the ones place. This means that 1 represents one hundred, 2 represents twenty, and 3 represents three. So when we put these digits together, we get the number 123.

Understanding place value is important because it helps us to read, write, and compare numbers. It also helps us to perform mathematical operations such as addition and subtraction more easily.

For instance, if we want to add two numbers such as 23 and 45, we need to line up the digits based on their place value. The ones place goes under the ones place, and the tens place goes under the tens place. Then we can add each column separately to get our answer of 68.

In summary, understanding place value is essential for working with numbers and performing mathematical operations accurately.

Thank you for listening!

The measure of angle x, y and z is 85⁰, 45⁰ and 40⁰ respectively.

The measure of angle x, y and z is calculated by applying intersecting chord theorem as shown below;

Angle y is calculated as follows;

10⁰ = ¹/₂ (arc EA - AN )

10 = ¹/₂ (65 - y )

20 = 65 - y

y = 65 - 20

y = 45⁰

The value of arc angle x is calculated as follows;

165 + 65 + 45 + x = 360 (sum of angles in a circle)

275 + x = 360

x = 360 - 275

x = 85⁰

The value of angle z is calculated as follows;

z = ¹/₂ (arc GE - GN )

z = ¹/₂ (165 - 85)

z = 40⁰

To graph the line that passes through the coordinates (2, 3), (3, 4.5), (4, 6), and (6, 9), we can use the slope-intercept form of the equation of a line, which is y = mx + b.

To start, we can find the slope of the line using any two points on the line. Let's use the first and last points:

slope = (change in y) / (change in x) slope = (9 - 3) / (6 - 2) slope = 1.5

Now we can choose any of the four given points and plug in the slope to find the y-intercept, b. Let's use the second point:

4.5 = 1.5(3) + b b = 0.75

So the equation of the line is:

y = 1.5x + 0.75

To graph the line, we can plot the four given points and then connect them with a straight line. Alternatively, we can choose any two values of x and plug them into the equation of the line to find the corresponding values of y, and then plot the resulting points.

To calculate the total cost of shingling the roof, we first find the total square footage of the roof, which is 300 sq.ft. We then multiply this by the cost per square foot of the shingles, $2.13, to get a total cost of $639.

The first step is to calculate the total square footage of the roof. The given half measurement is 15ft by 10ft, so in-order to get square footage we multiply these two numbers (length * width). 15ft * 10ft = 150sq.ft. Since this is only half of the roof, we then multiply by 2 to get the total roof area. So, 150sq.ft * 2 = 300sq.ft.

The next step is to find the total cost. If the cost of 1 sq.ft. of shingles is $2.13, we just multiply the total area by the cost per square foot.  So, 300sq.ft. * $2.13/sq.ft = $639.

Therefore, it will cost $639 to shingle the entire roof.
