(Based on Q1 ~ Q3) According to the Bureau of the Census, 18.1% of the U.S. population lives in the Northeast, 21.9% inn the Midwest, 36.7% in the South, and 23.3% in the West.. In a random sample of 200 recent calls to a national 800-member hotline, 39 of the calls were from the Northeast, 55 from the Midwest, 60 from the South, and 46 from the West. At the 0.05 level, can we conclude that the geographical distribution of hotline callers could be the same as the U.S. population distribution?

Answer:

In my school library you are going to be charged a fixed amount till when you return the book

Step-by-step explanation:

Borrowing of materials from library has time-lines, and special fines or penalty clause when it comes to defaulting of agreement when books are meant to be returned.

This penalty clause may differ from from one library to another.

I will cite my school library as an example.

If the time to return a book is due, the library charges a fixed amount from the due date till when ever one returns the book

A disease has hit a city. The percentage of the population infected t days after the disease arrives is approximated by ​p(t)equals7 t e Superscript negative t divided by 13 for 0less than or equalstless than or equals39. After how many days is the percentage of infected people a​ maximum? What is the maximum percent of the population​ infected?

Answers

Answer:

t = 13 days

p(13) = 33.47%

Step-by-step explanation:

p(t) is the percentage of the population infected:

p(t) = 7*t*e∧(-t / 13)

where    0 ≤ t ≤ 39 days

we can apply p'(t) = 0  to get number of days where the percentage of infected people is maximum:

p'(t) = (7*t*e∧(-t / 13))' = 7*(t*e∧(-t / 13))' = 7*((t)'*e∧(-t / 13)+t*(e∧(-t / 13)') = 0

⇒  7*(1*e∧(-t / 13)+t*e∧(-t / 13)*(-1 / 13)) = 7*e∧(-t / 13)*(1 - (t / 13)) = 0

∴  1 - (t / 13) = 0    ⇒    t = 13 days

then we get the maximum percent of the population​ infected as follows

p(13) = 7*13*e∧(-13 / 13)

⇒  p(13) = 33.47%

Need help with this question all parts (Use the image on cypto to help solve the question)

Answers

Explanation

Part a

We first need to find the encoding and decoding functions used by Boris and Natasha. We know that these two must be linear functions with 1 as the coefficient of x. Then the encoding function must have the form:

f(x)=x+b

Where x is the number associated with the letter and b is a constant that we don't know. The decoding function is its inverse:

f^(-1)(x)=x-b

Now let's take a look at the table that associates the letters with numbers. The minimum number is 1 associated with A and the maximum is 27 associated with Blank. Now let's write the encoded version of these two:

\begin{gathered} f(1)=1+b \n f(27)=27+b \end{gathered}

And let's find the difference between their encoded values:

f(27)-f(1)=(27+b)-(1+b)=27-1+b-b=27-1=26

So the difference between their encoded values is the same as the difference between their decoded values. Since 1 and 27 are the minimum and maximum decoded values their difference is the greatest of all the difference between two decoded values. Then there's no other pair of decoded values with a difference equal to 26 and since the difference between two encoded values is the same as the difference between two decoded values we can assure that 26 is the maximum difference between two encoded values and it corresponds to the pair A - Blank.

This implies that if the difference between the minimum and maximum value in the message sent by Boris and Natasha is 26 we can assure that this pair of values is the one corresponding to A and Blank.

Part b

The minimum and maximum values in the message are 15 and 41 and their difference is 41 - 15 = 26. This means that 15 is the encoded value of A and 41 is that of Blank. Then we can construct two equations using the encoding function:

\begin{gathered} f(1)=1+b=15 \n f(27)=27+b=41 \end{gathered}

By substracting 1 from both sides of the first equation and 27 from both sides of the second equation we obtain b:

\begin{gathered} 1+b-1=15-1\Rightarrow b=14 \n 27+b-27=41-27\Rightarrow b=14 \end{gathered}

So b=14 and the encoding function is f(x)=x+14.

Then the decoding function is f⁻¹(x) = x - 14.

Part c

Now we need to decode the message. We simply need to evaluate the decoding function at all the numbers in the encoded message:

\begin{gathered} f^(-1)(25)=25-14=11 \n f^(-1)\left(19\right)=19-14=5 \n f^(-1)(30)=30-14=16 \n f^(-1)(41)=41-14=27 \n f^(-1)(17)=17-14=3 \n f^(-1)(15)=15-14=1 \n f^(-1)(26)=26-14=12 \n f^(-1)(27)=27-14=13 \n f^(-1)(28)=28-14=14 \n f^(-1)(18)=18-14=4 \n f^(-1)(29)=29-14=15 \n f^(-1)(34)=34-14=20 \n f^(-1)(22)=22-14=8 \end{gathered}

Then we replace each encoded value by its respective decoded value so the message in numbers is:

11 5 5 16 27 3 1 12 13 27 1 14 4 27 4 15 27 20 8 5 27 13 1 20 8

Using the table associating numbers and letters we obtain the final message:

at -3 because you if f(0) that means the x is 0, but if f(x) =0 then for what x value does it the y = 0

I need to find the median and mean of a set of 8 numbers

8,8,10,10,10,12,13,16

Answers

Answer:

median = 10

mean = 10.9

Step-by-step explanation:

These are the answers because:

1) Whenever, there is an even set of numbers for the median, you have to take the two middle numbers in the number set given and then add them. After you add them, you have to divide them by 2.

In this case, it would be:

10 + 10 = 20

20/2 = 10

2) 10.9 is the answer for mean because first, you need to add all the numbers in the set. If you add

8 + 8 + 10 + 10 + 10 + 12 + 13 + 16 you would get 87. Then, you have to divide by how many numbers there are in the number set. In this case it would be 87/8 which is 10.875

Once you round it, you will get 10.9

Hope this helps!
