Shante is calculating the amount of time it takes a rocket to get to the moon. The moon is around 239,000 miles from Earth. How many hours would it take a rocket that can travel at 200 miles per minute to travel to the moon? Round to the nearest hour.

Answer:

x = -4

Step 1: Take all the constants on one side and the variables on the other.

(2 × x) + 12 = 4

=> (2 × x) = 4 - 12

(2 × x) = -8

Step 2: Divide 2 both sides to isolate 'x'.

=> \(\frac{2x}{2}\) = \(\frac{-8}{2}\)

=> x = -4

Hoped this helped.

the values of the variable are simply labels or categories without any inherent order or ranking.

The scale of measurement that is used to rank order the observations for a variable is called the ordinal scale.

In the ordinal scale, the values of the variable can be ranked or ordered, but the differences between the values may not be meaningful or consistent. For example, we can rank the finishes of runners in a race from 1st to 10th place, but we cannot necessarily say that the difference between 1st and 2nd place is the same as the difference between 5th and 6th place.

In contrast, in the interval scale and the ratio scale, the differences between the values are consistent and meaningful. In the nominal scale, the values of the variable are simply labels or categories without any inherent order or ranking.

Step-by-step explanation:

It is False that based only on the r and p values listed above you can come to the conclusion that age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.

In the given scenario, it is not completely true that based only on the r and p values listed above, you can come to the conclusion that age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.

Let's first understand what is meant by the term "moderator.

"Moderator: A moderator variable is a variable that changes the strength of a connection between two variables. If there is a statistically significant bivariate relationship between the amount of texting during driving and the number of accidents, scientists investigate whether this bivariate relationship is moderated by age.

Therefore, based on the values of r and p, it is difficult to determine if age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.

As we have to analyze other factors also to determine whether the age is a moderator or not, such as the sample size, the effect size, and other aspects to draw a meaningful conclusion.

So, it is False that based only on the r and p values listed above you can come to the conclusion that age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.

2) \(\sigma =\sqrt{\dfrac{\sum \left (x - \bar{x} \right )^{2}}{n}}\)

3) That 95% of the grades are between the values of 72.1 and 93.4

Step-by-step explanation:

1) From the given information, the mean and standard deviation re determined as \(\bar x\) = 82.75 and σ = 10.65

2) To find the standard deviation

a) We find the mean, \(\bar x\) by summing the data, x, and dividing the summation by the the number of data points, n

b) From each of the data, the mean is subtracted and the difference is squared (multiplied by itself)

c) The mean of the squares from above is found by adding them together and dividing by the number of data points

d) The square root of the mean of the squares from the previous step is then found and that is the standard deviation

3) The standard deviation tells how varied the data in the population is and the standard deviation of 10.65 in the question tells us that 95% of the grades are between 82.75 - 10.65 and 82.75 + 10.65 which is the range between 72.1 and 93.4.

Step-by-step explanation:

Let a be adult at premiere.

Let c be children at premiere.

Equation 1:-    a + c = 600

Let 13a be total price of tickets for adults.

Let 2c be total price of tickets for children.

Equation 2:-   13a + 2c = 2630

Solve simultaneously for c to determine children at premiere.

Make c the subject from Equation 1 to get Equation 3.

Equation 3:-  c = 600 - a

Substitute c's value in Equation 3 in Equation 2

13a + 2 (600 - a) = 2630

13a + 1200 -2a = 2630

11a = 2630 -1200

11a  = 1430

a = 130

Substitute value of a in Equation 3

c = 600 - 130

c = 470

Answer:

(9\(\sqrt{2}\))/2

Step-by-step explanation:

a diagonal divides the square into two right-angle triangles. Given that the two sides are the same length, and the hypothenuse is 9 cm, this applies:

2(a^2) = b^2 (a = side, b = hypothenuse)

2(a^2) = 9^2 (find for a)

2(a^2) =  81

a^2 = 81/2

a =\(\sqrt{81/2}\)

a = (9\(\sqrt{2}\))/2 or 6.3639 (rounded)

For a square having a diagonal 9 cm, its side will be  \(9/\sqrt{2}cm\).

Square is quadrilateral having 4 sides of equal length with measurement of all four angles as 90 degrees. It has two diagonals of equal length which bisects each other at  90 degrees.

Given the measure of the diagonal of a square,d is 9cm.

Let, the side of a square is a.

Using, the concept that the diagonal of a square is \(\sqrt{2} a\).

\(d=a\sqrt{2}\\\)

On substituting d=9,

\(9=a\sqrt2\\a=9/\sqrt2\)

The correct statements regarding activity diagrams are:

a. There can be multiple end points, but only one starting point.

c. A branch can have multiple incoming arrows.

d. A decision point may have more than 2 outgoing arrows.

e. An indeterminacy is created when the successors of an activity have non-mutually exclusive conditions.

f. An activity can be nested within another activity.

Activity diagrams are graphical representations used in software engineering to depict the flow of activities or actions within a system. The correct statements regarding activity diagrams are as follows:

a. There can be multiple end points, but only one starting point:

Activity diagrams typically illustrate the flow of activities from a single starting point to multiple end points. This allows for depicting different termination points in the system's behavior.

c. A branch can have multiple incoming arrows:

A branch in an activity diagram represents a decision point where the flow of activities can diverge. It is possible for multiple incoming arrows to converge at a branch, indicating different paths leading to the decision point.

d. A decision point may have more than 2 outgoing arrows:

A decision point in an activity diagram represents a condition or a decision that determines the subsequent flow of activities. It is possible for a decision point to have more than two outgoing arrows, indicating different paths based on the decision outcome.

e. An indeterminacy is created when the successors of an activity have non-mutually exclusive conditions:

In an activity diagram, if the subsequent activities following a certain action have conditions that are not mutually exclusive, it creates an indeterminacy. This means that multiple paths may be followed simultaneously based on the different conditions.

f. An activity can be nested within another activity:

Activity diagrams support the nesting of activities within each other. This allows for representing complex activities or sub-processes within a larger activity, providing a hierarchical structure to the diagram.

In conclusion, the correct statements regarding activity diagrams include multiple end points and a single starting point, the possibility of multiple incoming arrows at a branch, the presence of more than two outgoing arrows at a decision point, the creation of indeterminacy with non-mutually exclusive conditions, and the ability to nest activities within one another.

Answer:

(y-8)(y-8)

(y + 8)^2

Step-by-step explanation:

To factor the perfect square trinomial "y^2-16y+64" into two binomials, we need to find two binomials that multiply to give the trinomial.

Let's use the formula (y + n)(y + m), where n and m are integers.

If we set n = 8 and m = 8, we get:

(y + 8)(y + 8) = y^2 + 16y + 64

So, the perfect square trinomial y^2 - 16y + 64 can be factored into the binomials (y + 8)^2.

Note that the depreciation for this vehicle using method 2 will be $340.

To calculate the depreciation using method 2, we need to multiply the cost of the car by the depreciation rate per mile, which is given in cents per mile.

First, we need to calculate the total depreciation for the car in cents by multiplying the miles driven by the depreciation rate per mile:

Total depreciation = Miles driven x Depreciation rate per mile

Total depreciation = 10,000 x 3.4 cents per mile

Total depreciation = 34,000 cents

Next, we need to convert the total depreciation from cents to dollars by dividing it by 100:

Total depreciation = 34,000 cents ÷ 100 cents/dollar

Total depreciation = $340

Therefore, the depreciation for this vehicle using method 2 will be $340.

a. the current IRR on this project is approximately 7.49%.

b. The current MARR (Minimum Acceptable Rate of Return) is not given in the question. Please provide the MARR value so that we can calculate it.

c. The answer to whether they should invest or not depends on the comparison between the IRR and the MARR. Once the MARR value is provided, we can compare it with the calculated IRR to determine if they should invest.

a. The current IRR (Internal Rate of Return) on this project can be found by using linear interpolation with x₁ = 7% and x₂ = 8%. Let's calculate it:

We have the following cash flows: Year 0: -150,000 Year 1: 60,000 Year 2: 75,000 Year 3: 90,000 Year 4: 105,000

Using x₁ = 7%: NPV₁ = -150,000 + 60,000/(1+0.07) + 75,000/(1+0.07)² + 90,000/(1+0.07)³ + 105,000/(1+0.07)⁴ ≈ 2,460.03

Using x₂ = 8%: NPV₂ = -150,000 + 60,000/(1+0.08) + 75,000/(1+0.08)² + 90,000/(1+0.08)³ + 105,000/(1+0.08)⁴ ≈ -8,423.86

Now we can use linear interpolation to find the IRR:

IRR = x₁ + ((x₂ - x₁) * NPV₁) / (NPV₁ - NPV₂) = 7% + ((8% - 7%) * 2,460.03) / (2,460.03 - (-8,423.86)) ≈ 7.49%

Therefore, the current IRR on this project is approximately 7.49%.

b. The current MARR (Minimum Acceptable Rate of Return) is not given in the question. Please provide the MARR value so that we can calculate it.

c. The answer to whether they should invest or not depends on the comparison between the IRR and the MARR. Once the MARR value is provided, we can compare it with the calculated IRR to determine if they should invest.
