Answer:
14/3
Step-by-step explanation:
When 56 shares are evenly distributed between 12 people, each person gets equal number of shares.
The number of shares gotten by each person is the ratio of the total number of shares to the total number of people. It is given by the formula:
number of shares gotten by each person = total number of shares / total number of people
number of shares gotten by each person = 56 shares / 12 people
number of shares gotten by each person = 14/3 shares
East High wants to estimate the number of seniors who plan to go to a 4-year college. 1) Which of the following surveys probably would best represent the entire population of seniors? a) 25 glee club members are randomly selected; 16 plan to go to a 4-year college. b) 25 honor roll students are randomly selected from the senior class; 14 plan to go to a 4-year college. c) 25 seniors are randomly selected; 13 plan to go to a 4-year college. 2) There are 650 seniors at East High. Using your answer from part (a), estimate the number of seniors who plan to go to a 4-year college.
A is probably the one that would represent most of the population since it has a bigger fraction.
And it would be around 410 seniors who would plan to go to a 4-year college.
We have to determine whether the following surveys probably would best represent the entire population of seniors.
What is the probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.
Therefore, A is probably the one that would represent most of the population since it has a bigger fraction.

An estimated 416 seniors plan to attend a 4-year college.
Now, For the number of seniors who plan to go to a 4-year college, we can use the proportion of seniors in the sample who plan to attend a 4-year college and apply it to the entire senior class.
From the sample in option a), 16 out of 25 seniors plan to attend a 4-year college.
To estimate the number of seniors who plan to attend a 4-year college, we can use the following proportion:
16/25 = x/650
Solving for x, we get:
x = (16/25) x 650
x = 416
Therefore, an estimated 416 seniors plan to attend a 4-year college.

Valentina le tocó 6 , a Camila 3 y a Hania partes del pastel.

¿Quién comió más pastel? Camila
¿Qué fracción de pastel comieron entre las tres?
¿Qué fracción de pastel sobró?
Answer:
Camila y Hania fueron las que comieron más pastelEntre las tres comieron [tex]\frac{5}{6}[/tex] de pastelSobró [tex]\frac{1}{6}[/tex] de pastelStep-by-step explanation:
La pregunta está mal formulada. Debería ser :
A Valentina le tocó 1/6 , a Camila 1/3 y a Hania 2/6 del pastel.
Para responder a la pregunta de quién comió más pastel podemos proceder de varias formas.
Una forma es expresar las fracciones de manera decimal :
Valentina : [tex]\frac{1}{6}=0.1666[/tex]
Camila : [tex]\frac{1}{3}=0.3333[/tex]
Hania : [tex]\frac{2}{6}=0.3333[/tex]
Así nos daríamos cuenta de que Camila y Hania fueron las que comieron más pastel (Vale aclarar que Camila y Hania comieron la misma cantidad).
Otra posible forma es igualando los denominadores de las fracciones y comparando sus numeradores.
Por ejemplo, [tex]\frac{1}{3}[/tex] se puede expresar como [tex]\frac{1}{3}=\frac{2}{6}[/tex] (multiplicamos por dos tanto al numerador como al denominador) ⇒ las nuevas fracciones correspondientes a lo que comió cada una son :
Valentina : [tex]\frac{1}{6}[/tex]
Camila : [tex]\frac{2}{6}[/tex]
Hania : [tex]\frac{2}{6}[/tex]
Dado que todas las fracciones tienen el mismo denominador (seis) comparamos ahora sus numeradores y nos damos cuenta de nuevo que Camila y Hania fueron las que comieron más pastel.
Con las tres fracciones con el mismo denominador (seis) procedemos a responder la segunda pregunta :
¿Qué fracción de pastel comieron entre las tres?
Para averiguarlo sumaremos las fracciones de pastel que comió cada una :
[tex]\frac{1}{6}+\frac{2}{6}+\frac{2}{6}=\frac{5}{6}[/tex]
Encontramos que entre Valentina, Camila y Hania comieron [tex]\frac{5}{6}[/tex] de pastel.
Finalmente, para averiguar que fracción de pastel sobró debemos restarle al total (uno) la fracción de pastel que comieron entre las tres :
[tex]1-\frac{5}{6}=\frac{1}{6}[/tex]
Esto se debe a que el ''uno'' representa el ciento por ciento del pastel (el total). Encontramos que sobró [tex]\frac{1}{6}[/tex] de pastel.
Camila fue quien más comió, ya que comió el doble que las demás. Entre las tres, comieron 2/3 del pastel, por lo que sobró 1/3 del mismo.
Dado que Valentina, Camila y Hania cumplen años el mismo día, y al momento de partir el pastel a Valentina le toco 1/6, a Camila 1/3 y a Hania 1/6 partes del pastel, para determinar quién comió más pastel, qué fracción de pastel comieron entre las tres y qué fracción de pastel sobró se deben realizar los siguientes cálculos:
¿Quién comió más pastel?1/6 = 0.1661/3 = 0.333Por lo tanto, Camila fue quien comió más pastel. ¿Qué fracción de pastel comieron entre las tres?1/6 + 1/6 + 1/3 = 2/6 + 1/3 = 2/3Por lo tanto, entre las tres comieron 2/3 del pastel.¿Qué fracción del pastel sobró?1 - 2/3 = 1/3Por lo tanto, sobró 1/3 del pastel.Aprende más en https://brainly.com/question/1301963

Step-by-step explanation:
Suppose a change of coordinates T:R2→R2 from the uv-plane to the xy-plane is given by x=e−2ucos(5v), y=e−2usin(5v). Find the absolute value of the determinant of the Jacobian for this change of coordinates.
Complete Question
The complete question is shown on the first uploaded image
Answer:
The solution is [tex]\frac{\delta (x,y)}{\delta (u, v)} | = 10e^{-4u}[/tex]
Step-by-step explanation:
From the question we are told that
[tex]x = e^{-2a} cos (5v)[/tex]
and [tex]y = e^{-2a} sin(5v)[/tex]
Generally the absolute value of the determinant of the Jacobian for this change of coordinates is mathematically evaluated as
[tex]| \frac{\delta (x,y)}{\delta (u, v)} | = | \ det \left[\begin{array}{ccc}{\frac{\delta x}{\delta u} }&{\frac{\delta x}{\delta v} }\\\frac{\delta y}{\delta u}&\frac{\delta y}{\delta v}\end{array}\right] |[/tex]
[tex]= |\ det\ \left[\begin{array}{ccc}{-2e^{-2u} cos(5v)}&{-5e^{-2u} sin(5v)}\\{-2e^{-2u} sin(5v)}&{-2e^{-2u} cos(5v)}\end{array}\right] |[/tex]
[tex]Let \ a = -2e^{-2u} cos(5v), \\ b=-2e^{-2u} sin(5v),\\c =-2e^{-2u} sin(5v),\\d=-2e^{-2u} cos(5v)[/tex]
So
[tex]\frac{\delta (x,y)}{\delta (u, v)} | = |det \left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right] |[/tex]
=> [tex]\frac{\delta (x,y)}{\delta (u, v)} | = | a * b - c* d |[/tex]
substituting for a, b, c,d
=> [tex]\frac{\delta (x,y)}{\delta (u, v)} | = | -10 (e^{-2u})^2 cos^2 (5v) - 10 e^{-4u} sin^2(5v)|[/tex]
=> [tex]\frac{\delta (x,y)}{\delta (u, v)} | = | -10 e^{-4u} (cos^2 (5v) + sin^2 (5v))|[/tex]
=> [tex]\frac{\delta (x,y)}{\delta (u, v)} | = 10e^{-4u}[/tex]

Answer:
what's the Question???
Step-by-step explanation:
What information can you obtain about the scores in a regular frequency distribution table that is not available from a grouped table.
A. The number and width of the class intervals
B. The exact frequency for each category on the scale of measurement
C. The overall frequency for each class interval
Answer: B. The exact frequency for each category on the scale of measurement
Step-by-step explanation: The main difference between a grouped table and regular frequency distribution exists in the fact that ; grouped table takes in a defined range of (X) values, that is takes more than one individual value per group and takes the frequency of all scores or values in the group, hence giving the frequency of the scores in the interval rather than the frequency of each individual score. On the other hand, the regular frequency distribution treats values or scores individually and then takes the frequency of each score. This way a regular frequency distribution enables us to know the exact number or distribution of each individual score.
The information in a regular frequency distribution table that is not available from a grouped table is (b) the exact frequency for each category on the scale of measurement
There are several similarities between a regular frequency table, and a grouped frequency table.
However, both frequency tables have a major difference.
This difference is in the frequency of the data they represent
While a regular frequency table shows the exact frequency of each data element, a grouped frequency table cannot show the exact frequency of each data element.
Hence, the true option is (b)

A) 92 ounces B) 102 ounces C) 112 ounces D) 122 ounces
This question is Incomplete because it lacks the diagram of the box plot. Please find attached the diagram of the box plot
Answer:
B) 102 ounces
Step-by-step explanation:
Looking at the attached diagram, we can see the box plot it divided into different segment
The median weight of the babies = 110 ounces
The maximum weight of the babies is between = 140 and 130, approximately let's say 135 ounces
The minimum weight is 80 ounces
Then the box in the middle is divided into 3
It has the First Quartile
Median
And third Quartile
Since we have 160 infants born in the local hospital, about 40 of the birthweights we fall into
= 40/160 = 1/4
1/4 represents the first Quartile
Looking at the box plot, 40 of the birthweights were below 102 ounces.
