Answer:

Therefore, 32  is he total number of vehicles sold at the dealership last month.

Step-by-step explanation:

We know that the ratio of the number of sedans to the number of trucks to the number of vans sold at the dealership last month was 4:5:7, respectively. We have :

[tex]4:5:7 \implies 4x+5x+7x=16x[/tex]

Therefore, 16x is he total number of vehicles sold at the dealership last month.

We know that:

1) The number of vans sold at the dealership last month was between 10 and 20.

2) The number of sedans sold at the dealership last month was less than 10

We get:

[tex]10\leq 7x \leq 20\\\implies x=2\\\\\\4x\leq 10\\x=1 \, \vee \, x=2[/tex]

We know that x is a positive integer. In order to satisfy both conditions, this is possible only if x = 2.

We get [tex]16x=16\cdot 2=32[/tex]

Therefore, 32  is he total number of vehicles sold at the dealership last month.

Answer:

The value of the [tex]13^{th}[/tex] term is ≈ 1.

Step-by-step explanation:

A geometric sequence is a series of numbers where each term is computed by multiplying the previous term by a constant, r also known as the common ratio.

The formula to compute the [tex]n^{th}[/tex] term of a GP is: [tex]a_{n}=a_{1}\times r^{n-1}[/tex]

Here, a₁ is the first term.

It is provided that a₄ = 19625 and a₉ = 95.

Determine the value of a₁ and r as follows:

[tex]\frac{a_{4}}{a_{9}}=\frac{a_{1}r^{4-1}}{a_{1}r^{9-1}} \\\frac{19625}{95}= \frac{r^{3}}{r^{8}}r^{5}=\frac{95}{19625}\\ r=(\frac{95}{19625})^{1/5}\\=0.344[/tex]

The common ratio is, r = 0.344.

The value of a₁ is:

[tex]a_{4}=19625\\a_{1}\times(0.344)^{3}=19625\\a_{1}=\frac{19625}{0.040707584} \\=482096.898\\\approx482097[/tex]

The first term is, a₁ = 482097.

13th term of this geometric sequence is:

[tex]a_{13}=a_{1}\times r^{13-1}\\=482097\times (0.344)^{12}\\=1.3234\\\approx1[/tex]

Thus, the [tex]13^{th}[/tex] term is approximately equal to 1.

Answer:

0.0223

Step-by-step explanation:

Given the following data x(1) = 377, n(1) = 422, x(2) = 431, n(2) = 518

The sample proportion is the number of success divided by the sample.

P(1) = x(1)/n(1) = 377/422 = 0.8934

P(2) = x(2)/n(2) = 431/518 = 0.8320

Formular for the standard error of the difference in sample proportions

S.E = √p(1)q(1)/n(1)+P(2)q(2)/n(2)

S.E = √p1(1-P1)/n1+P2(1-P2)/n2

By substitution we have that,

S.E = √0.8934(1-0.8934)/422+0.8320(1-0.8320)/518

S.E = 0.0223

The domain for n is  [tex]-\infty<n<\infty[/tex]

Explanation:

The arithmetic sequence is    

To determine the domain of the sequence, let us consider  [tex]a_n[/tex] as  [tex]f(n)[/tex]  

Thus, the sequence becomes,  [tex]f(n)=4-4(n-1)[/tex]  

The domain of the function is the set of all x-values for which the function is real and well defined.

Since, the function has no domain constraints or undefined points. Therefore, the domain of the function is

Thus, the domain of the arithmetic sequence  [tex]a_n=4-4(n-1)[/tex] is  [tex]-\infty<n<\infty[/tex]

Answer:

The response does not seem reasonable.

Step-by-step explanation:

The current price of shorts is a sum of the original price plus profit. In this case, a simple formula is given:

Profit = Selling price  - Buying price

Therefore, the selling price can be anything less than $ 41.

Expressing the information in a linear equation gives x ≤ 41

where x is the buying price of the shorts.

To determine if David's answer that the original price of the shorts was $41 seems reasonable, we can use an equation to represent the situation. By solving the equation, we find that the original price of the shorts is $21.98, not $41.

To determine if David's answer that the original price of the shorts was $41 seems reasonable, we can use an equation to represent the situation. Let's assume the original price of the shorts is x dollars.

If the total cost of the T-shirt and shorts, including tax, is $22.45 as given, we can write the equation: x + 1.47 = 22.45.

Simplifying the equation, we subtract 1.47 from both sides: x = 21.98.

Therefore, the original price of the shorts would be $21.98, not $41. Hence, David's answer does not seem reasonable.

The final velocity is 15.8 m/s in the forward direction

Step-by-step explanation:

An inelastic collision occurs when the two object after the collision stick together.

In any case, the total momentum of the system is conserved before and after the collision, in absence of external forces. Therefore, we can write:

[tex]p_i = p_f\\m u + MU = (m+M)v[/tex]

where in this problem:

m = 1300 kg is the mass of the small sedan

u = 20 m/s is the initial velocity of the small sedan

M = 7100 kg is the mass of the truck

U = 15 m/s is the initial velocity of the truck

v is the final combined velocity of the small sedan + truck

Here we have taken both the velocity of the sedan and the truck in the positive (forward) direction

Solving the equation for v, we find the final velocity:

[tex]v=\frac{mu+MU}{m+M}=\frac{(1300)(20)+(7100)(15)}{1300+7100}=15.8 m/s[/tex]

And since the sign is positive, this means that is direction is the same as the initial direction of the sedan and the truck, so forward.

Answer:

263,606.9

Step-by-step explanation:

In 2004 the population in Morganton, Georgia, was 43,000.

(0, 43000)

The population in Morganton doubled by 2010

In 6 years the population is doubled (86000)

(6,86000)

[tex]A= a(b)^t[/tex]

Use (0,43000) in the above equation

[tex]A= a(b)^t\\43000= a(b)^0\\a=43000[/tex]

Now plug in (6,86000)

[tex]A= a(b)^t\\A= 43000(b)^t\\86000=43000(b)^6\\2=b^6\\b=\sqrt[6]{2} \\b=1.12[/tex]

[tex]A=43000(1.12)^t[/tex]

Now find out A when t=16 (2020)

[tex]A=43000(1.12)^t\\A=43000(1.12)^{16}\\A=263606.9[/tex]

If the growth rate from 2004 to 2010 continues, the expected population in Morganton, Georgia in 2020 would be around 172,000 as the population is doubling every 6 years.

The population of Morganton, Georgia in 2004 was 43,000 and it doubled by 2010 to 86,000. This shows a constant growth rate in which the population size doubles every 6 years. If this rate of growth remains consistent, the population of Morganton is expected to double again by 2020. Therefore, by 2020, the population of Morganton, Georgia could be around 172,000 people.

The location of the reflected post will be in the first quadrant at point (3, 2).

To reflect a point across the y-axis, we simply negate the x-coordinate while keeping the y-coordinate unchanged.

Given the point (-3, 2), when we reflect it across the y-axis, the x-coordinate becomes positive 3, while the y-coordinate remains 2. Therefore, the reflected point is (3, 2).

Since the original point (-3, 2) lies in the second quadrant (negative x, positive y), the reflected point (3, 2) will lie in the first quadrant (positive x, positive y).

Answer:

Maximum number of 3x3x2 bricks = 23.

Step-by-step explanation:

The volume of the box = 13 x 8 x 4 = 416 cubic unit

The volume of the brick with the dimensions = 18 cubic unit

Now as per the question, we want to fill an empty box with 416 cubic unit with the help of bricks which are 18 cubic unit each.

The maximum number of bricks required to fill the box = Volume of the box ÷ Volume of one brick.

→ The number of bricks required to fill the box = 416 ÷ 18 = 23.11

But, number of bricks can never be in fraction so it means a maximum of 23 bricks can accommodate in the given box. We will not choose 24 or more than 24 bricks because these much bricks will go out of the dimensions.

Note: Volume of a cuboid = length x breadth x height (l x b x h).

To solve the problem, you divide each dimension of the box by the corresponding dimension of the brick, rounding down to the nearest whole number to get the number of bricks that can fit in each direction. You then multiply these together to get the total. In this case, a maximum of 16 bricks can fit.

The problem at hand requires spatial reasoning and division. The challenge is to determine how many 'bricks' (which we'll engage as 3x3x2 units) can fit into a larger 'box' (which is 13x8x4 units). This can be determined by individually dividing the dimensions of the box by the dimensions of the brick.

For instance, considering the length, we divide 13 by 3 to get approximately 4.33. Considering that we can't fractionate a brick, we can place only 4 bricks along the length. Using the same approach, we divide 8 by 3 for the width to get approximately 2.67, and we can place 2 bricks here. It's the same for the height; 4 divided by 2 is 2. Therefore, we can place 2 bricks along the height.

To get the total number of bricks that can fit in the box, multiply the numbers together: 4 (length) x 2 (width) x 2 (height), giving a result of 16 bricks. Hence, a maximum of 16 bricks of size 3x3x2 can fit into a box of size 13x8x4 without going out of the box or overlapping.

The first three iterations are 1.67, 1.56 and 1.52

Step-by-step explanation:

Given the function g(x)=1/3x+1

To get the first threw iteration with initial value of x = 2

First iteration at x= 2:

g(2) = 2/3+1

g(2) = (2+3)/3

g(2) = 5/3 = 1.67

Second iteration will be when x = g(2) = 5/3

g²(2) = g(5/3) = 1/3(5/3) + 1

g²(2) = g(5/3) = 5/9 + 1

g²(2) = g(5/3) = 14/9 = 1.56

Third iteration will be at when

x = g²(2) = 14/9

g³(2) = g(14/9) = 1/3(14/9) + 1

g³(2) = g(14/9) = 14/27 + 1

g³(2) = g(14/9) = 41/27 = 1.52

The first three iterations are 1.67, 1.56 and 1.52

The ladder reaches approximately 19.8 feet up the side of the house, as determined using the Pythagorean theorem.

The question is asking us to find the height the ladder reaches up the side of the house. This is a problem dealing with right triangles and can be solved using the Pythagorean theorem, which is a^2 + b^2 = c^2, where 'a' and 'b' are the shorter sides (base and height of the house) and 'c' is the hypotenuse (the ladder).

In this case, the ladder is 24 feet long (this is our c), and the base of the ladder is 13 feet from the house (this is our a). We are trying to find b (the height of the house the ladder reaches).

Substitute these values into the Pythagorean theorem and solve for 'b':

13^2 + b^2 = 24^2
b^2 = 24^2 - 13^2
b = sqrt(24^2 - 13^2)

So, the height that the ladder reaches up the side of the house is approximately 19.8 feet.

the area of a rectangle is base * height. so 6 * 3 = 18

Answer: the length is 6 inches and the width is 3 inches.

Step-by-step explanation:

Let L represent the length of the rectangular note card.

Let W represent the width of the rectangular note card.

The formula for determining the area of a rectangle is expressed as

Area = L × W

Area of the note card would be

LW = 18 - - - - - - - - - - - - 1

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

Perimeter of the note card would be

2(L + W) = 18

(L + W) = 9 - - - - - - - - - - - - 2

Substituting L = 9 - W into equation 1, it becomes

W(9 - W) = 18

9W - W² = 18

W² - 9W + 18 = 0

W² - 6W - 3W + 18 = 0

W(W - 6) - 3(W - 6) = 0

W - 6 = 0 or W - 3 = 0

W = 6 or W = 3

Substituting W = 3 into equation 1, it becomes

3L = 18

L = 18/3 = 6

The area of the rectangle TOUR is 80.00 unit².

Step-by-step explanation:

The area of a rectangle is computed using the formula:

[tex]Area\ of\ a\ Rectangle=length\times width[/tex]

Since the dimensions of the rectangle are not provided we can compute the dimensions using the distance formula for two points.

The distance formula using the two point is:

[tex]distance=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]

Considering the rectangle TOUR the area formula will be:

Area of Rectangle TOUR = TO × OU

The co-ordinates of the four vertices of a triangle are:

T = (-8, 0), O = (4, 4), U = (6, -2) and R = (-6, -6)

Compute the distance between the vertices T and O as:

[tex]TO=\sqrt{(4-(-8))^{2}+(4-0)^{2}}\\=\sqrt{12^{2}+4^{2}} \\=\sqrt{160} \\=4\sqrt{10}[/tex]

Compute the distance between the vertices O and U as:

[tex]OU=\sqrt{(6-4)^{2}+(-2-4)^{2}}\\=\sqrt{2^{2}+6^{2}} \\=\sqrt{40} \\=2\sqrt{10}[/tex]

Compute the area of rectangle TOUR as follows:

[tex]Area\ of\ TOUR=TO\times OU\\=4\sqrt{10}\times 2\sqrt{10}\\=80\\\approx80.00 unit^{2}[/tex]

Thus, the area of the rectangle TOUR is 80.00 unit².
