On Julie's door, the images will span 210 square inches.

As Julie printed six images, the total space that the images cover is:

6 x 35 square inches = 210 square inches

Inches are measured as 1/36 of a yard in both British Imperial and American Customary measurement systems. According to some sources, the term "inch" comes from the Old English "ince" or "ynce," which in turn is said to have originated from the Roman "uncia" unit.

The name of another English unit, the ounce, is derived from the Roman word uncia. According to legend, King David I of Scotland defined the old English word "ynce" as the width of a man's thumb at the base of the nail in the year or thereabouts 1150 AD.

From the question:

Six images total, each measuring 5 by 7 inches, were printed by Julie. We must first calculate the area of each image in order to add up the overall area that these photographs cover.

One image's area is as follows:

5 inches x 7 inches = 35 square inches

As Julie printed six images, the total space that the images cover is:

6 x 35 square inches = 210 square inches

Consequently, 210 square inches of Julie's door will be covered by the images.

The average speed in mph is 2 mph

Average Speed is the total distance that something has traveled by the total amount of time it took it to travel that distance. It is also the total distance traveled by the moving object and the amount of total time the object spent moving.

Average speed = Distance traveled/Time taken

Where Distance traveled = 4/10 mile

Time taken = 1/5 of an hour

To get the average speed in mph,

Average speed = (4/10)/(1`/5)

Average speed = 4/10 * 5/1

Average speed = 20/10

Average speed = 2 mph

Therefore, the average speed is 2mph

To solve this problem, we need to find the present value of the cash flow stream using a discount rate of 12%. We can use the present value formula:

PV = CF1/(1+r)^1 + CF2/(1+r)^2 + CF3/(1+r)^3 + CF4/(1+r)^4

where PV is the present value, CF1, CF2, CF3, and CF4 are the cash flows at time 1, 2, 3, and 4 respectively, and r is the discount rate.

Substituting the values given in the problem, we get:

PV = 690/(1+0.12)^1 + 365/(1+0.12)^2 + 220/(1+0.12)^3 + 330/(1+0.12)^4

PV = 690/1.12 + 365/1.2544 + 220/1.4049 + 330/1.5735

PV = 616.07 + 290.76 + 156.51 + 209.38

PV = 1272.72

Therefore, the present value of the cash flow stream is $1,272.72.

Answer:

Step-by-step explanation:

If 24, x and 18 are in proportion, then we have:

24 : x = x : 18

This can be rewritten as:

x^2 = 24 x 18

x^2 = 432

Taking the square root of both sides, we get:

x = ± 20.7846

However, we also know that (x - 1) is in proportion with 24 and 18. Therefore:

24 : (x - 1) = (x - 1) : 18

This can be rewritten as:

(x - 1)^2 = 24 x 18

(x - 1)^2 = 432

Taking the square root of both sides, we get:

x - 1 = ± 20.7846

Solving for x in each case, we get:

x = 21.7846 or x = -19.7846

However, we can see that the value x = -19.7846 does not make sense in the context of the problem (since we cannot have a negative value for the number of something). Therefore, we can reject it as an extraneous solution.

Hence, the value of x is:

x = 21.7846

Answer: 21.7846

We take the positive root:

n = (-3 + 27) / 2 = 12. Therefore, there were 12 people in the original group of winners.

Let's assume that there were n people in the original group of winners, and each person's share was x dollars. Then we know that:

n * x = $90,000,000

After three more winners are declared, the total number of winners becomes n + 3. Each person's share is then reduced by $1,000,000, so the new share per person is (x - $1,000,000). We can then write:

(n + 3) * (x - $1,000,000) = $90,000,000

Expanding the equation, we get:

nx - $1,000,000n + 3x - $3,000,000 = $90,000,000

Simplifying, we get:

nx + 3x = $1,000,000n + $93,000,000

Factoring out x and n, we get:

x(n + 3) = $1,000,000(n + 3) + $90,000,000

Dividing both sides by (n + 3), we get:

x = $1,000,000 + ($90,000,000 / (n + 3))

We can substitute this expression for x in the first equation:

n * ($1,000,000 + ($90,000,000 / (n + 3))) = $90,000,000

Expanding and simplifying, we get:

[tex]$n^2$[/tex]+ 3n - 270 = 0

Using the quadratic formula, we get:

n = [tex](-3\± \sqrt{(729)) / 2[/tex]

n = (-3 ± 27) / 2

Since n has to be positive, we take the positive root:

n = (-3 + 27) / 2 = 12

Therefore, there were 12 people in the original group of winners.

The probability that a 42 person shift will put together between 193.2 and 201.6 computers per hour is given as follows:

0.0006 = 0.06%.

The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is obtained by the equation presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The parameters for this problem are given as follows:

[tex]\mu = 4.2, \sigma = 0.8, n = 42, s = \frac{0.8}{\sqrt{42}} = 0.1234[/tex]

The probability that a 42 person shift will put together between 193.2 and 201.6 computers per hour is equivalent to the probability of a sample mean between 193.2/42 = 4.6 and 201.6/42 = 4.8.

The probability is the p-value of Z when X = 4.8 subtracted by the p-value of Z when X = 4.6, hence:

Z = (4.8 - 4.2)/0.1234

Z = 4.86

Z = 4.86 has a p-value of 1.

Z = (4.6 - 4.2)/0.1234

Z = 3.24

Z = 3.24 has a p-value of 0.9994.

Hence:

1 - 0.9994 = 0.0006 = 0.06%.

Answer: Since the spinners have 5 and 6 numbers respectively, the total number of outcomes is 5 x 6 = 30.

If we get the same number as a previous spin, it means that the first spin is irrelevant, and we only care about the second spin. Therefore, the probability of getting the same number as a previous spin is the same as the probability of getting any specific number on the second spin, which is 1 out of 6.

Therefore, the probability of getting the same number as a previous spin is 1/6, or approximately 0.17 to two decimal places.

Step-by-step explanation:

To find the magnitude of the cross product of vectors a and b, we can use the formula:

|a x b| = |a| |b| sin(θ)

where |a| and |b| are the magnitudes of vectors a and b, and θ is the angle between them.

First, let's calculate the cross product of vectors a and b:

a x b = (2i + j + 8k) x (i + 3j + 4k)

= (j)(4k) - (8k)(3j) - (i)(4k) - (j)(2i) + (8k)(i) - (2i)(i + 3j)

= -10i - 20j - 20k

Next, let's find the magnitudes of vectors a and b:

|a| = √(2^2 + 1^2 + 8^2) = √(69)

|b| = √(1^2 + 3^2 + 4^2) = √(26)

Finally, we need to find the angle θ between vectors a and b. We can use the dot product to find cos(θ):

a · b = (2i)(i) + (1j)(3j) + (8k)(4k) = 2 + 3 + 32 = 37

|a| |b| cos(θ) = a · b

cos(θ) = a · b / (|a| |b|)

cos(θ) = 37 / (√(69) √(26))

cos(θ) ≈ 0.893

Using the fact that sin^2(θ) + cos^2(θ) = 1, we can solve for sin(θ):

sin(θ) = √(1 - cos^2(θ))

sin(θ) ≈ 0.449

Substituting the values we found into the formula for the magnitude of the cross product, we get:

|a x b| = |a| |b| sin(θ)

|a x b| = √(69) √(26) (0.449)

|a x b| ≈ 26.81

Therefore, the magnitude of the cross product of vectors a and b is approximately 26.81.

The solution for the system of equation -2y=-6x-18 3x-4y=27 is (x, y) = (-3, 9).

A system is an organized set of components that work together to achieve an overall goal. It could be a physical system, such as an automobile, or an abstract system, such as an economic system.

The first step is to isolate one of the variables in one of the equations. To do this, we can multiply both sides of the first equation by -3. This will give us: 6y = 18x + 54.
Next, we need to subtract this equation from the second equation. Doing so gives us: 3x - 6y = -27.
Now we can isolate the variable y. To do this, we can divide both sides of the equation by -6. This will give us: y = -3x - 9.
We have now isolated the variable y in both equations, so we can substitute y = -3x - 9 in the first equation. Doing so gives us: -2(-3x - 9) = -6x - 18.
We can then simplify this equation to get: 6x + 18 = -6x - 18.
Finally, we can solve this equation for x. Doing so gives us x = -3. We can then substitute this value into either equation to find the value of y: y = -3(-3) - 9 = 9.
Therefore, the solution for the system of equation -2y=-6x-18 3x-4y=27 is (x, y) = (-3, 9).

Therefore, the volume of the truncated cuboid is approximately 68 + 4*√(30) cubic meters.

Volume is a measure of the amount of space occupied by a three-dimensional object. It is the amount of three-dimensional space enclosed by the boundaries of an object. Volume is typically measured in cubic units, such as cubic meters (m³) or cubic centimeters (cm³).

Here,

The truncated cuboid is a solid figure that is obtained by cutting off the top of a rectangular prism (cuboid) with a plane that is parallel to the base. The formula for the volume of a truncated cuboid is:

V = h/3 * (A + √(A*B) + B)

where V is the volume, h is the height of the truncated portion, A is the area of the top face, and B is the area of the base face.

In this case, the height of the truncated portion is 3 m, the top face has an area of 5 m x 8 m = 40 m², and the base face has an area of 8 m x 1.5 m = 12 m². Therefore:

A + B = 40 + 12 = 52 m²

√(AB) = √(4012) = √(480) = 4*√(30)

Since M = 2S, M = 2 x 2400 = 4800

So

Mark gets $4800
Sofia gets $2400

The ratio of the amounts obtained
4800: 2400: 1200

Dividing by 1200 gives us
4800/1200: 2400/1200: 1200/1200

= 4 : 2 : 1
