Therefore, the value of n that makes the system of equations true is n = 10.

Given:

p = 2n

p - 5 = 1.5n

Substituting the value of p from the first equation into the second equation, we have:

2n - 5 = 1.5n

Next, we can solve for n by subtracting 1.5n from both sides of the equation:

2n - 1.5n - 5 = 0.5n - 5

Simplifying further:

0.5n - 5 = 0

Adding 5 to both sides of the equation:

0.5n = 5

Dividing both sides by 0.5:

n = 10

Therefore, the value of n that makes the system of equations true is n = 10.

The 95% confidence interval for the amount of time spent on personal issues is (4.805, 4.95).

Mean time that employees spend on personal issues each week(M) = 4.9 hours

Standard deviation = 0.35 hours

The following formula is used to get the confidence interval for the sample mean and standard deviation given:

μ = M ± t(sM)

where; M = sample mean

t = T-statistic based on confidence interval

Degree of freedom = n - 1

From the question, n = 55

Degree of freedom = 55 - 1

Degree of freedom = 54

(Standard errors)sM = √(s^2/n)

Now putting the value

sM = √(0.352/55)

sM = 0.05

t = 2.005 This is determined using the Excel formula =T.INV.2T at a confidence level of 0.95 and a degree of freedom of 55-1=54. (0.05,54)

Now the confidence interval

μ = M ± t(sM)

μ = 4.9 ± 2.005 × 0.05

μ = 4.9 ± 0.095

μ = (4.9 - 0.095, 4.9 + 0.095)

μ = (4.805, 4.95)

1.1) The volume of the cube is 27 cubic centimeters. 1.2)the density of the ice cube is approximately 0.917 grams per cubic centimeter (g/cm³).

1.3) the mass of the water cube is 27 grams. 1.4) the weight of the water and the ice would be the same under the same conditions. 1.5)In simpler terms, ice floats on water because it is lighter (less dense) than the water, allowing it to displace an amount of water equal to its weight and float on the surface.

1.1) The volume of the cube can be calculated using the equation: Volume = width x height x length. In this case, the cube measures 3 cm wide, 3 cm tall, and 3 cm long, so the volume is:

Volume = 3 cm x 3 cm x 3 cm = 27 cm³.

Therefore, the volume of the cube is 27 cubic centimeters.

1.2) Density is defined as mass divided by volume. The mass of the ice cube is given as 24.76 grams, and we already determined the volume to be 27 cm³. Therefore, the density of the ice cube is:

Density = Mass / Volume = 24.76 g / 27 cm³ ≈ 0.917 g/cm³.

Therefore, the density of the ice cube is approximately 0.917 grams per cubic centimeter (g/cm³).

1.3) The volume of the water cube is the same as the ice cube, which is 27 cm³. Given the density of liquid water as 1.00 g/cm³, we can calculate the mass of the water cube using the equation:

Mass = Density x Volume = 1.00 g/cm³ x 27 cm³ = 27 grams.

Therefore, the mass of the water cube is 27 grams.

1.4) The weight of an object depends on both its mass and the acceleration due to gravity. Since the volume of the water cube and the ice cube is the same (27 cm³), and the mass of the water cube (27 grams) is equal to the mass of the ice cube (24.76 grams), their weights would also be equal when measured in the same gravitational field.

Therefore, the weight of the water and the ice would be the same under the same conditions.

1.5) Ice floats on water because it is less dense than liquid water. The density of ice is lower than the density of water because the water molecules in the solid ice are arranged in a specific lattice structure with open spaces. This arrangement causes ice to have a lower density compared to liquid water, where the molecules are closer together.

When ice is placed in water, the denser water molecules exert an upward buoyant force on the less dense ice, causing it to float. The buoyant force is the result of the pressure difference between the top and bottom surfaces of the submerged object.

In simpler terms, ice floats on water because it is lighter (less dense) than the water, allowing it to displace an amount of water equal to its weight and float on the surface.

The dimensions of the poster with the smallest area are 48 cm by 16 cm.

Let the width of the printed material be x cm and the height be y cm. Then the total width of the poster including the margins is (x + 16) cm, and the total height is (y + 24) cm.

The total area of the poster is the area of the printed material plus the area of the margins:

(x + 16)(y + 24) = 1536

Expanding the left side, we get:

xy + 16y + 24x + 384 = 1536

Rearranging terms, we get:

xy = 1152 - 16y - 24x

To find the dimensions of the poster with the smallest area, we want to minimize the product xy subject to the constraint given by the equation above.

One way to do this is to use the method of Lagrange multipliers. Let L = xy + λ[(x + 16)(y + 24) - 1536] be the Lagrangian, where λ is a Lagrange multiplier. Setting the partial derivatives of L with respect to x, y, and λ equal to zero, we get:

y + 16λ = 0

x + 24λ = 0

(x + 16)(y + 24) = 1536

From the first two equations, we get:

x = -24λ

y = -16λ

Substituting these into the third equation, we get:

(-24λ + 16)(-16λ + 24) = 1536

Simplifying, we get:

-6λ + 4 = 0

Therefore, λ = 2/3. Substituting this into the expressions for x and y, we get:

x = -16

y = -32

These values give the dimensions of the printed material. To find the dimensions of the poster, we add the margins:

width = x + 16 + 16 = 48 cm

height = y + 24 + 24 = 16 cm

Therefore, the dimensions of the poster with the smallest area are 48 cm by 16 cm.

Answer: In 2 seconds the car covered a distance of 55.56 meters.

Uniform rectilinear motion (also known as uniform linear motion or straight-line motion) is a type of motion in which an object moves along a straight line with a constant speed.

This means that the object's position changes by the same amount in a given period of time, regardless of the time that has elapsed. This type of motion is different from accelerated motion, in which the speed of an object changes over time. In uniform rectilinear motion, the speed of the object is constant, and the direction of motion does not change.

Data:

V = 100 km/h = 27.78 m/s

t = 2 s

d = ?

Since it asks us to calculate the distance in meters, we must convert from km/h to m/s.

        \(\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{V=100 \ \frac{\not{km}}{\not{h}}*\left(\frac{1000 \ m}{1\not{km}}\right)*\left(\frac{1\not{h}}{3600 \ s}\right)= 27.78 \ m/s } \end{gathered}$} }\)

The uniform motion formula is: V=d/t

The area of the surface generated by revolving the given curve about the y-axis is (3/8) (3√(16) − 3√(2)) m².

The surface area of the given curve when it is revolved about the y-axis is calculated by the method of integration. First, we need to determine the boundaries of the integral.

Since the given curve is revolved about the y-axis, the boundaries of the integral will be the y-intercepts of the given curve. The y-intercept of the given curve is y = -7. Hence, the limits of integration are -7 and 9/2.

Now, we need to determine the equation of the curve that is generated on revolving the given curve about the y-axis. This equation can be obtained by substituting the x-variable with the magnitude of the distance from the origin to the point on the curve along the y-axis. Thus, the equation of the curve is y = 4√(y+7).

The surface area can be calculated by integrating the equation of the curve with respect to y. The area of the surface generated by revolving the given curve about the y-axis is A = ∫5/2 -7 4√(y+7) dy. The value of this integral is A = (3/8) (3√(16) − 3√(2)) m². Hence, the area of the surface generated by revolving the given curve about the y-axis is (3/8) (3√(16) − 3√(2)) m².

Given: Two teams play a series of games that ends when one of them has won i games. Suppose that each game played is, independently, won by Team A with a probability of p. We need to find the expected number of games that are played when (a)i=2 and (b) i=3.

Also show in both cases that the number is maximized when p=1/2.Solution: Let N be the expected number of games played. Then the number of games played must be N if the series is won by A in i - 1 games, and N + i if it is won in i games. Then we have N = (1-p)N + p(N+1) ; here (1-p) is the probability that A does not win the game, and p is the probability that A wins the game

N = 1/pi.e., the expected number of games played until a win for A is 1/p, so the expected number of games played when i=2 is 1/p+1/p+1=2/p+1, and the expected number of games played when   \(i=3 is 3/p+2/p+1/p+1=6/p+1\).  In order to maximize both of these quantities, we must maximize \(p(1-p)^{i-1} for i=2 and i=3.\)

We could use calculus to find the maximum value, but instead we can use AM-GM: For i=2,p(1-p) ≤ ((p) + (1-p))/2 = 1/2, \(i=2,p(1-p) ≤ ((p) + (1-p))/2 = 1/2\)with equality when p = 1/2.

Similarly, for i=3,p(1-p)^2 ≤ ((p) + (1-p) + (1-p))/3 = 1/4, \(i=3,p(1-p)^2 ≤ ((p) + (1-p) + (1-p))/3 = 1/4\)with equality when p = 1/2. So the expected number of games played is minimized when p=1/2.

The rate of the current is 1.5 mph, and the length of the course is 9 miles.

Let's assume the rate at which Ben paddles in still water is represented by r (in mph), and the rate of the current is represented by c (in mph).

When paddling upstream, Ben is paddling against the current, so his effective speed is reduced. The time it takes him to complete the course is 6 hours, and the distance he covers is represented by d (in miles). Using the formula d = (r - c) * t, we have d = (r - c) * 6.

When paddling downstream, Ben is paddling with the current, so his effective speed is increased. The time it takes him to complete the course is 2 hours. Using the same formula, we have d = (r + c) * 2.

We can solve these two equations to find the values of r and c. By dividing the second equation by the first equation, we get (r + c)/(r - c) = 1/3.

Solving this equation, we find r = 4 mph and c = 1.5 mph.

Therefore, the rate of the current is 1.5 mph, and the length of the course is determined by substituting r and c into either of the original equations. The length of the course is 9 miles.
