Find the range and standard deviation of the set of data.4, 7, 4, 7, 7, 9, 11The range is(Simplify your

Answers

SOLUTI0N

Step 1 :

In this question, we are meant to find the range and standard deviation of the set of the data:

4, 7, 4, 7, 7, 9, 11

For the Range, we have that:

\(\begin{gathered} \text{Range = Highest number - Smallest number } \\ =\text{ 11 - 4} \\ =7 \end{gathered}\)

Step 2 :

For the Standard Deviation,

We have that :

\(\text{Standard Deviation =}\frac{\sqrt[]{\sum ^{\infty}_{n\mathop=0}(X_{i\text{ }}-X)^2}}{n}\)

So, we need to evaluate using the following process,

\(\begin{gathered} \text{Mean, X = }\frac{4\text{ + 7 + 4 + 7 +7 + 9 + 11}}{7} \\ =\frac{49}{7} \\ =\text{ 7} \end{gathered}\)

Next, we evaluate the following :

Variance =

\(\frac{(4-7)^2+(7-4)^2+(4-7)^2+(7-7)^2+(7-7)^2+(9-7)^2+(11-7)^2}{7}\)

=

\(\begin{gathered} \frac{9\text{ + 9 + 9 + 0 + 0 + 4 + 4}}{7} \\ =\text{ }\frac{35}{7} \\ =\text{ 5} \end{gathered}\)

Next, we have that :

Standard Deviation =

\(\sqrt[\square]{Variance}\)

=

\(\begin{gathered} \sqrt[\square]{5} \\ =\text{ 2. 236} \\ =\text{ 2. 2}4\text{ ( nearest hundredth )} \end{gathered}\)

CONCLUSION:

The Range = 7 and the Standard Deviation = 2. 24

Write a function rule that gives the total cost c(p) of p pounds of sugar if each pound costs $0.59.


A. c(p) = p + 0.59

B. c(p) = 59p

C. c(p) = p/0.59

D. c(p) = 0.59p

Answers

Answer:

D. c(p) = 0.59p

Step-by-step explanation:

The total cost, c(p), to purchase sugar is equal to the product of the pound cost equal to $0.59 and the number of pounds of sugar, p. Thus, the answer to this item is C(p)=0.59p

The total cost, c(p), to purchase sugar is equal to the product of the pound cost equal to $0.59 and the number of pounds of sugar, p. Thus, the answer to this item is,

                                c(p) = ($0.59)p

We multiply the number of pounds of sugar, p, time the cost per pound ,.59, to get the total cost

c(p) = .59*p

y f(n) = sin nπ/2 then G(n) = 2/π² (Sin nπ/2 - Sin² nπ/2)

Answers

The function G(n) in terms of f(n) is G(n) = 2/π² (f(n) - f²(n)).

To find the function G(n) in terms of f(n) based on the given expression, we substitute f(n) into the formula for G(n):

G(n) = 2/π² (Sin nπ/2 - Sin² nπ/2)

Replacing Sin nπ/2 with f(n), we have:

G(n) = 2/π² (f(n) - Sin² nπ/2)

Since f(n) is defined as f(n) = Sin nπ/2, we can simplify further:

G(n) = 2/π² (Sin nπ/2 - Sin² nπ/2)

Now we can substitute f(n) = Sin nπ/2 into the equation:

G(n) = 2/π² (f(n) - f²(n))

Therefore, the function G(n) in terms of f(n) is G(n) = 2/π² (f(n) - f²(n)).

What is the absolute value function?

The absolute value function is defined by:

|x| = x, x >= 0.

|x| = -x, x < 0.

The absolute value function measures the distance of a point x to the origin, that is, the distance to x = 0. From this, we get that |x| = a can mean either that:

x = a, or;

x = -a.

In this problem, the equation is given by:

Hence:

Answers

The probability that the battery fails before the one-year warranty expires on the computer is 0.0041. So, option e) is correct.

Let X be the length of the life (in years) of a battery for a computer that has a distribution that can be described by the pdf:

\(f(x)=\frac{x}{121} e^\frac{-x^2}{242}\).

We need to find the probability that the battery fails before the one-year warranty expires on the computer, that is P[X<1].

\(P[X<1]=\int\limits^1_0 {f(x)} \, dx\).

Substitute the value of f(x) in the integral above.

\(P[X<1]=\int\limits^1_0 {\frac{x}{121} e^\frac{-x^2}{242}} \, dx\).

Let \(\frac{-x^2}{242}=t\).

Differentiate both sides to get xdx/121=dt.

Thus, we have that:

\(P[X < 1]=\int\limits^1_0 {\frac{x}{121} e^\frac{-x^2}{242}} \, dx\\P[X < 1]=\int\limits^\frac{1}{242} _0 {e^{-t} } \, dt\\ P[X < 1]=-[e^{\frac{-1}{242}}-1]\\P[X < 1]=1-e^{\frac{-1}{242}}\\ P[X < 1]=0.0041\)

From the first table, we can use the points (-1,3) and (5,-3) to find the first equation:

\(\begin{gathered} \text{slope:} \\ m=\frac{y_2-y_1}{x_2-x_1} \\ \Rightarrow m=\frac{-3-3}{5-(-1)}=\frac{-6}{5+1}=\frac{-6}{6}=-1 \\ m=-1 \end{gathered}\)

then we can use the point to find the equation in slope-point form:

\(\begin{gathered} y-y_1=m(x-x_1) \\ \Rightarrow y-3=-1(x-(-1))=-x-1 \\ \Rightarrow y=-x-1+3=-x+2 \\ y=-x+2 \end{gathered}\)

Which statement describes the graph of f/x )=- 4x 3 28x 2 32x 64?

Answers

The statement that describes the end behavior of the graph f(x) = -4x³ + 28x² + 32x + 64.

The graph increases to left and decreases to right.

How to obtain the end behavior of the polynomial?

The end behavior of a polynomial function is given by the limits of the function as x approaches infinity, meaning that only the term with the highest exponent is considered for the calculation of the limit.

In this problem, the function is defined as follows:

f(x) = -4x³ + 28x² + 32x + 64.


Considering only the highest exponent, we have that:

f(x) = -4x³.

Hence the behavior of the graph of the function at the left tail is given as follows:

lim x -> -∞ f(x) = -4(-∞)³ = -4 x (-∞) = ∞.

(increases to the left).

At the right tail, the behavior is given as follows:

lim x -> ∞ f(x) = -4 x (∞)³ = -4 x (∞) = -∞.

(decreases to right).

Missing Information

The problem is incomplete, hence we suppose that it asks for us to describe the end behavior of the graph.

A project has an initial cost of $30 million.The project is expected to generate a cash flow of $2.85 million at the end of the first year.All the subsequent cash flows will grow at a constant growth rate of 3.85% forever in future.If the appropriate discount rate of the project is 11%,what is the profitability index of the project? a.1.917 b.1.328 c.1.387 d.1.114 ortcehov e. None of the above

Answers

Profitability index is 1.387. Thus, the correct option is (c) 1.387.

The formula for calculating the profitability index is:

P.I = PV of Future Cash Flows / Initial Investment

Where,

P.I is the profitability index

PV is the present value of future cash flows

The initial investment in the project is $30 million. The cash flow at the end of the first year is $2.85 million.

The present value of cash flows can be calculated using the formula:

PV = CF / (1 + r)ⁿ

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

n is the number of periods

For the first-year cash flow, n = 1, CF = $2.85 million, and r = 11%.

Substituting the values, we get:

PV = 2.85 / (1 + 0.11)¹ = $2.56 million

To calculate the present value of all future cash flows, we can use the formula:

PV = CF / (r - g)

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

g is the constant growth rate

For the subsequent years, CF = $2.85 million, r = 11%, and g = 3.85%.

Substituting the values, we get:

PV = 2.85 / (0.11 - 0.0385) = $39.90 million

The total present value of cash flows is the sum of the present value of the first-year cash flow and the present value of all future cash flows.

PV of future cash flows = $39.90 million + $2.56 million = $42.46 million

Profitability index (P.I) = PV of future cash flows / Initial investment

= 42.46 / 30

= 1.387

Therefore, the correct option is (c) 1.387.

Answer:

x=9

Step-by-step explanation:

Substitute y for 4x

4x=8x-36

Then solve for x

-4x=-36

x=9

Answer: x=9

Explanation: begin by substituting or replacing “y” with 4x since y=4x. This should give you the new equation of 4x=8x-36. Then subtract 8x from both sides so that it will cancel out 8x and leave you with 4x-8x=-36. Then combined like terms to then give you -4x=-36. Lastly, divide each side by -4 which will give you the answer of x=9 because when you divide -4 by -36, two negatives cancel each other out and leave you with a positive outcome.

What are the formulas to find the perimeter and the area of a rectangle?

The formula to find the perimeter of a rectangle=2(Length+Breadth)

The formula to find the area of a rectangle=Length×Breadth.

Given that, a small garden has a perimeter of 24 1/4 ft and the length is 8 ft.

Now, perimeter = 2(8+Breadth)

⇒24 1/4=16+2×Breadth

⇒97/4-16=2×Breadth

⇒Breadth=97-64/4×2=33/8 ft

Now, Area=8×33/8=33 ft²

Therefore, the area of the garden is 33 ft².

Given that, the floor measures 4 1/2 ft by 3 3/4 ft.

The area of a floor=Length×Breadth=9/2×15/4=135/8 ft²

Number of tiles to cover the floor=135/8=16.875

Therefore, the number of tiles required to cover the floor is 17 tiles.

Given that, a dog pen is 3 1/3 yards wide by 5 2/3 yards long.

Answers

The area of the wafer is 1590.43 cm² and the number of dies the same wafer can contain if each die has a side of 4 cm is 63

the braille system of representing characters was developed early in the nineteenth century by louis braille. the charac- ters, used by the blind, consist of raised dots. the positions for the dots are selected from two vertical columns of three dots each. at least one raised dot must be present. how many distinct braille characters are possible?

Answers

The Braille system uses two vertical columns of three dots each to represent characters. There are 8 possible combinations for each column, giving a total of 64 distinct Braille characters.

The Braille system of representing characters was developed by Louis Braille in the early nineteenth century. This system is used by blind people and consists of raised dots that represent characters. The positions for the dots are selected from two vertical columns of three dots each. At least one raised dot must be present to represent a character.


To determine the number of distinct Braille characters possible, we need to consider the number of ways we can arrange the dots in the two vertical columns. Each column has three dots, and we need to choose which of these three dots to raise to represent a character. This gives us a total of 2^3 = 8 possible combinations for each column.

Since we have two columns, we can multiply the number of possible combinations for each column to get the total number of distinct Braille characters. This gives us 8 x 8 = 64 possible characters.

16. You decide to drop a penny off the top of the Willis Tower (fromerly the Sears Tower) in Chicago, IL. The
height of the penny (in feet) can be represented by the equation h= -16t2 + 1451 where t is time (in seconds).
a) How long will it take for the penny to hit the ground? Show any work that leads to your answer.

Answers

Answer:

9.5 seconds.

Step-by-step explanation:

We know that the equation that represents the height of the penny as a function of time is:

h(t) = -16*t^2 + 1451

Where the height is in ft, and the time is in seconds.

a) We want to know how long takes the penny to hit the ground.

Well, the penny will hit the ground when its height is equal to zero.

Then we need to solve for t:

h(t) = 0 = -16*t^2 + 1451

0 = -16*t^2 + 1451

16*t^2 = 1451

t^2 = 1451/16 = 90.7

t = √90.7 = 9.5

This means that it takes 9.5 seconds to hit the ground.

Answer:9.5 seconds
