Approximately 304,657,600 Americans were there in July 2009 based on the estimated 2008 growth rate of 0.88%.

To find the approximate US population in July 2009, we need to apply the growth rate of 0.88% to the initial population in July 2008.

Convert the growth rate from percentage to decimal:

0.88% = 0.0088
Calculate the number of people added to the population in 2008: 302,000,000 * 0.0088 = 2,657,600
Add this number to the initial population to find the population in July 2009:

302,000,000 + 2,657,600 = 304,657,600.

Answer: 20y - 30

Step-by-step explanation:

distribute, then combine like terms.

Step-by-step explanation:

Final account amount will be  ( using compound interest formula)

90 000 (1 + .10)^3 = 119 790       <===     ( 1-% is .10 in decimal)

 subtract original amount to find interest =  £ 29 790.

Answer: £29,791.00

Step-by-step explanation:

Use the Equation \(A = P(1+r/n)^(nt)\)

P represents principal which is the starting amount.

R represents rate which is the percent increase represented in decimal form.

N represents the number of times compounded per year.

T represents the total time.

The question is asking us to solve for A which is the total amount and we just have to plug in all the other variables given to us and solve and subtract from the original.

A = 90,000(1 + 0.1/1)^(1*3)

A = 90,000(1.1)^3

A = 119,791.00

We have the amount, and now we have to subtract it from the original.

119,791-90,000 = 29791

Answer:

Step-by-step explanation:

The vertex form of an equation of the parabola:  

                                                       f(x) = a(x - h)² + k

the vertex is (7, -4)  ⇒   h = 7,  k = -4

so:

     f(x) = a(x - 7)² + (-4)

    f(x) = a(x - 7)² - 4

The parabola goes through the point (5, 8) ⇒   x=5,  f(x)=8

8 = a(5 - 7)²  - 4

8 = a(-2)²  - 4

+4           +4

12  = 4a

÷4       ÷4

a = 3

It means the equation of the parabola in vertex form:

                               f(x) = 3(x - 7)² - 4

Answer:

Let's solve for x.

9y+8=x

Step 1: Flip the equation.

x=9y+8

Answer:

x=9y+8

Let's solve for x.

−2x+8y=−36

Step 1: Add -8y to both sides.

−2x + 8y + −8y = −36 + −8y

−2x = −8y − 36

Step 2: Divide both sides by -2.

−2x  / −2  =  −8y − 36  / −2

x=4y + 18

Answer:

(26, 2)

x = 26

y = 2

Step-by-step explanation:

Given:

9y + 8 = x

-2x + 8y = -36

Substitute (9y + 8) for x in the second equation.

-2(9y + 8) + 8y = -36

Then distribute and solve.

-18y + (-16) + 8y = -36

Combine like terms.

-10y - 16 = -36

-10y = -20

y = 2

Solve for x by substituting the y value (2) into 9y + 8 = x.

9(2) + 8 = x

18 + 8 = x

x = 26

Therefore, the solution is (26, 2) in terms of (x, y).

The long run behavior of the function f(x)=5(2)x+1 is that it approaches 1 as x approaches negative infinity and it approaches infinity as x approaches positive infinity.

The long-term behavior of the function f(x)=5(2)x+1 can be discovered by examining how the function behaves as x gets closer to negative and positive infinity.

As x→−[infinity], f(x) = 5(2)^ -∞+1 = 5(0)+1 = 1

As x approaches negative infinity, the value of the function approaches 1.

As x→[infinity], f(x) = 5(2)^ ∞+1 = 5(∞)+1 = ∞

As x approaches positive infinity, the value of the function approaches infinity.

As a result, the function f(x)=5(2)x+1 behaves in the long run in such a way that it approaches 1 as x approaches negative infinity and infinity as x approaches positive infinity.

The new points after dilation are

(3/2, -3) and (9/2,-3)

Step-by-step explanation:

Here in this question, we want to give the new points of the line segment after it is dilated by a particular scale factor.

What is needed to be done here is to multiply the coordinates of the given line segment by the given scale factor.

Let’s call the positions on the line segment A and B.

Thus we have;

A = (1,-2) and B = (3,-2)

So by dilation, we multiply each of the specific data points by the scale factor and so we have;

A’ = (3/2, -3) and B’= (9/2,-3)

The number of 5 digit integers that you can make using each of 1, 2, 3, 4, 5, 6 and 0 once is given as follows:

Step-by-step explanation:

25 GB is equal to 25,000 MB. if we wanted to find the number of MB in 10 GB, we would multiply 10 by 1000, which would give us 10,000 MB.

1 GB is equal to 1000 MB, so to find the number of MB in 25 GB we need to multiply 1000 MB by 25. 1000 MB x 25 = 25,000 MB, which means that 25 GB is equal to 25,000 MB. To determine the number of MB in a certain number of GB, simply multiply the number of GB by 1000. For example, if we wanted to find the number of MB in 10 GB, we would multiply 10 by 1000, which would give us 10,000 MB. Therefore, 10 GB is equal to 10,000 MB.

Answer:

10010110

Step-by-step explanation:

A binary number is basically a number in base 2. So, each place represents a power of two. The ones place represents 1 or 2^0, the tens represents 2 or 2^1, the hundreds represents 4 or 2^2 and so on. To find the highest place needed to make in the number in binary, we find the greatest power of two that is below 150. In this case, it is 128. We can start by writing 128 in binary:

10000000

Now, we subtract 128 from 150 and find the largest power of two that is smaller than the difference. The largest power of 2 smaller than 22 is 16, so we put a one in the place for 2^4:

10010000

We can subtract 16 from 22 to get what is leftover to continue the process. We get 6, and the largest power of 2 smaller is 4. We can place a one in the hundreds place to represent it:

10010100

What is left is 6-4 or 2, which is just 2^1, so we can place it in the tens place:

10010110

The point of intersection between the planes is (4/3, -1/3, 4/3).

Line of Intersection between Lines

The line of intersection is the line that represents the intersection of two planes. In this problem, we have to find the line of intersection between the lines and the intersection point of the planes. Here is how you can find the solution to this problem:

Given vectors and lines are: <3,-1,2>+<1,1,-1>

Line A = (x, y, z) = <3,-1,2> + t<1,1,-1><-8,2,0> +t<-3,2,-7>

Line B = (x, y, z) = <-8,2,0> + s<-3,2,-7>

The direction vector of Line A = <1,1,-1>

The direction vector of Line B = <-3,2,-7>

The cross product of direction vectors = <1,10,5>

Set the direction vector equal to the cross product of the direction vectors. (for the line of intersection)

<1,1,-1> = <1,10,5> + t<3, -2, 3> + s<-5, -6, 4>

By equating the corresponding components of each vector, you can write the equation in parametric form.

i.e. x + 1 = 3ty = 1z + 5 = 2t

On the other hand, x + 2 = s, y - 3 = -5s, and z + 4 = -2s are the equations of Line B.

We can solve this system of equations by substitution, and we get s = -1 and t = -2.

The point of intersection of the two lines is then given by (x, y, z) = (-5, 1, 1).

Point of Intersection between Planes

The point of intersection between the two planes is the point that lies on both planes.

Here is how you can find the solution to this problem:

Given planes are:-5x+y-2z=32

x-3y+5z=-7

You can solve the system of equations by adding the two equations together.

By doing this, you eliminate the y term. You get: -3x+3z=-4

The solution is x = 4/3 and z = 4/3.

By substituting these values into either equation, we get the value of y as -1/3.

Therefore, the point of intersection between the planes is (4/3, -1/3, 4/3).

Answer: Yes, it is a function.

Step-by-step explanation:

This question is:

"A relation between time and distance traveled by a biker is a function?"

Well, as you may know, a function is a relation where each value in the domain or input, has only linked one value in the range or output.

In this relation the domain is time and the range is the distance.

Now, as you know, at each given time, the distance of the biker can be only one (he can not be at different locations at the same time) so this relation is actually a function.

The expected number of minutes until the frogs stop jumping is 4, regardless of their initial positions.

Let's consider the probability that all three frogs are at different vertices at a given time. The first frog can land on any of the 12 vertices, the second frog can land on either of the two adjacent vertices to the first frog, and the third frog can land on either of the two adjacent vertices to the second frog that are not adjacent to the first frog. Therefore, the probability that all three frogs are at different vertices is:

\(P(all $ different) = 12 * 2/11 * 2/10 = 24/55\)

If all three frogs are at different vertices, then none of them can jump to the other two vertices adjacent to their current position, otherwise they will meet. Therefore, the next time they can meet is after the first jump of the frog that is alone, and this will happen with probability 1/3.

If two frogs meet, the expected number of minutes until the third frog joins them is just the expected number of minutes until two frogs meet, which is the same as the expected number of minutes until the frogs stop jumping. Therefore, it suffices to compute the expected number of minutes until the frogs jump to the same vertex for the first time, given that all three frogs are at different vertices.

Let T be the expected number of minutes until the frogs jump to the same vertex for the first time. Conditioning on the first jump, we have:

\(T = 1/3 * 1 + 2/3 * (T + 1)\)

The first term corresponds to the case where the frog that is alone jumps to one of the two vertices adjacent to one of the other frogs and they meet. The second term corresponds to the case where the frog that is alone jumps to the vertex adjacent to the other frog and the third frog jumps to the same vertex with probability 1/2, or they jump to different vertices with probability 1/2 and we are back to the starting position, but with one less frog being alone.

Solving for T, we get:

T = 4

Therefore, the expected number of minutes until the frogs stop jumping is 4, regardless of their initial positions.

Step-by-step explanation:

The t statistic, t = 1.808, is calculated using the sample statistics from the high school (sample 1) and college (sample 2) groups. In order to determine if high school students carry more books than college students, we need to perform a hypothesis test.

Let's set up the hypotheses:

Null hypothesis (H0): The mean number of books carried by high school students is equal to the mean number of books carried by college students.

Alternative hypothesis (Ha): The mean number of books carried by high school students is greater than the mean number of books carried by college students.

Next, we'll perform a one-tailed independent samples t-test to compare the means of the two groups using the given t statistic, degrees of freedom (df), and alpha level (α).

Given the t statistic of 1.808 and the degrees of freedom (df) calculated as df = n1 + n2 - 2 = 17 + 17 - 2 = 32, we can consult a t-distribution table or use statistical software to find the critical value corresponding to our desired alpha level.

Finally, by comparing the calculated t statistic to the critical value, we can determine whether to reject or fail to reject the null hypothesis. If the calculated t statistic is greater than the critical value, we reject the null hypothesis and conclude that high school students carry more books than college students. Otherwise, if the calculated t statistic is less than or equal to the critical value, we fail to reject the null hypothesis and conclude that there is not enough evidence to support the claim that high school students carry more books than college students.
