In january of 2019, the american midwest experienced record-breaking freezing temperatures. A certain metropolitan area in wisconsin, with a residential population of over 1. 15 million, experienced daily average temperatures as low as minus 28 degrees fahrenheit. Hospitals saw a steady stream of patients reporting symptoms of frostbite. In the aftermath, a survey was conducted in order to estimate the true proportions of individuals afflicted by frostbite during the extreme weather. 289 residents were selected via simple random sampling and 273 reported not having any symptoms. What was the sample proportion obtained by the survey? give your answer to 3 decimal places. For help on how to input a numeric answer, please see instructions for inputting a numeric response.

What is a percentage?
The percentage is a mathematical operation that is expressed with the symbol "%" is a relationship that allows us to know the portion of an initial value to represent a set.
It could also be defined as a representation of an original value that lets us know a certain number of elements that we want from that original value or set.
To solve this problem, we use a simple rule of three to find the percentage value of the sample.
289 -------- 100%
273 --------- x
x = (273 * 100%) / 289
x = 94.46%
100% - 94.46% = 5.53%
The ratio in propotion with 3 decimals is
5.53/100 = 0.055

Two financial institutions offer different deals to new customers. The first bank offers an interest rate of 3% for the first year and 2 % for the next two years. The second bank offers an interest rate of 2.49 % for three years. You decide to invest the same amount of principal in each bank. To answer the following, assume you make no withdrawal or deposits during the three-year period.
b. Write a function that represents the total amount of money in the account in the second bank after three years.
Total amount of money in the account in the second bank after 3 years will be represented by the function: P[tex]e^{0.0747}[/tex].
The formula for calculating the amount (A) on a principal (P) invested at the rate of r%, compounded continuously after t years is-
A = P[tex]e^{rt}[/tex]
Here, we are given that there are 2 financial institutions-
1st financial institution:
interest rate = 3% for the first year
and interest rate for next two years = 2%
2nd Financial institution:
interest rate = 2.49% for three years
Let the principal amount deposited be P
We assume that the interest is compounded continuously.
Then for the 2nd bank-
Amount = P[tex]e^{rt}[/tex]
here, r = 2.49%
= 0.0249
Amount = P[tex]e^{0.0249 * 3}[/tex]
= P[tex]e^{0.0747}[/tex]
Thus, the total amount of money in the account in the second bank after 3 years will be given by the function- P[tex]e^{0.0747}[/tex].

Consider the sequence with first term 2 and second term 4. If these are the first two terms of a geometric sequence, what is the third term?
The third term of a given geometric sequence based on common ratio 2 is 8.
What is geometrical progression series?A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
Given a geometric sequence.
First term = 2
Second term = 4
Common ratio = Next term / previous term
Common ratio = 4/2 = 2
So,
Common ratio = Third term / second term
The third term = common ratio × second term
The third b = 2 × 4 = 8
Hence "The third term of a given geometric sequence based on common ratio 2 is 8".

Based on the alternate exterior angle theorem, if m<1 = m<2, the statement which is true is that: B. n || m.
What are parallel lines?Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.
What is the alternate exterior angle theorem?The alternate exterior angle theorem states that when two (2) parallel lines are cut through by a transversal, the alternate exterior angles that are formed are congruent or angles of equal measure.
In this context, we can reasonably infer and logically deduce that the true statement which best proves that lines n and m are parallel is that angle 1 is congruent to angle 2 because by definition, all alternate exterior angles are congruent, if two (2) parallel lines are cut by a transversal.

A punch recipe calls for one and 12 quarts of sparkling water and 3/4 of courts of grape juice how much of each ingredient would you need to make 75 quarts of punch sparkling water group juice
Answer:
a punch recipe calls for one and 12 quarts of sparkling water
Step-by-step explanation:
Answer:
Sparkling water: 50 quarts
Grape Juice: 25 quarts
Step-by-step explanation:
The punch recipe uses 1 1/2 quarts of water and 3/4 quarts of grape juice
That would make a total of
1 1/2 + 3/4 = 3/2 + 3/4 = 6/4 + 3/4 = 9/4 quarts of punch
Therefore to make 75 quarts, we have to figure out how many of 9/4 quarts would be needed.
This is 75 ÷9/4
Dividing by 9/4 is same as multiplying by 4/9
75 ÷9/4 = 75 x 4/9 = 300/9 = 100/3
So we will need 100/3 times as much of both ingredients
For sparkling water this would be
1 1/2 x 100/3 = 3/2 x 100/3 = 300/6 = 50 quarts
For grape juice we will need
3/4 x 100/3 = 300/12 = 25 quarts
(Or we can subtract 50 from 75 to get 25 quarts)

If the distribution is skewed right, the mean is greater than the median.
A distribution is said to be skewed right if more than half the area under the distribution curve is to the right of the mode of the distribution. Also the tail of the distribution will be longer on the right side. In this case, the distribution is said to be positively skewed.
Then the mean of the distribution will be greater than the median of the distribution.

By using the fact that the two lines with the purple arrow are parallel, We can conclude that the angles are y = 133° and x = 47°
How to find the measures of angles x and y?First, notice that the two lines with the purple arrow are parallel lines, and these lines are intersected by the same line, then the 4 angles formed in the above line are the same ones than in the below line.
So, if the angle in the fourth quadrant of the above intersection is the same as the angle in the fourth quadrant of the below intersection, then we can see that:
y = 133°
And x + y should be equal to 180°, then:
133° + x = 180°
x = 180° - 133° = 47°
We can conclude that the angles are y = 133° and x = 47°
