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

Suppose that the length X of the life (in years) of a battery for a computer has a distribution that can be described by the pdf: f(x) = x/121 e^-x^2/242 Determine the probability that the battery fails before the one year warranty expires on the computer. a) 0.1082 b) 0.2041 c) 0.9959 d) 0.0082 e) 0.0041 f) None of the above
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:
\(P[X < 1]=\int\limits^1_0 {\frac{x}{121} e^\frac{-x^2}{242}} \, dx\\P[X < 1]=\int\limits^\frac{1}{242} _0 {e^{-t} } \, dt\\ P[X < 1]=-[e^{\frac{-1}{242}}-1]\\P[X < 1]=1-e^{\frac{-1}{242}}\\ P[X < 1]=0.0041\)

Which statement describes the graph of f/x )=- 4x 3 28x 2 32x 64?
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 InformationThe problem is incomplete, hence we suppose that it asks for us to describe the end behavior of the graph.

Step-by-step explanation:
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
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.

suppose a wafer can contain multiple number of dies. for a die with 2 cm diagonal, the wafer can fit 500 of the dies. what is the wafer area and peripheral? then, how many dies the same wafer can contain if each die has a side of 4 cm?
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
If a wafer can contain 500 dies with 2 cm diagonal, then the wafer's diagonal length would be

Therefore, the area of the Wafer is 1590.43 cm².
The number of dies that can be fixed if die has a side of 4 cm,
√4√2 x 4√2 x X = 45
32X = 2025

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.
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
