Answer:

The probability that a person with adequate hydration completes the course = P(A. H) = (2/5) = 0.40

La probabilidad de que una persona con hidratación adecuada complete el curso = P (A. H) = (2/5) = 0.40

Step-by-step explanation:

English Translation and Question written written right

Based on the data in the table, find the probability that a person with adequate hydration can complete a 5 km run.

Number of people completing the course

Situations | A. H | I. H | Total

Play sports | 50 | 20 | 70

Not play sports | 10 | 70 | 80

Total | 60 | 90 | 150

Note that A. H stands for adequate hydration and I. H stands for inadequate hydration.

Solution

Probability of an event is expressed as the number of elements in that event divided by the number of elements in the sample space.

Mathematically,

P(E) = n(E) ÷ n(S)

So, for this Question, the probability that a person with adequate hydration completes course = P(A. H)

n(A. H) = Number of people that have adequate hydration and complete the course = 50 + 10 = 60

n(S) = Total number of people that completed the course = 150

P(A. H) = n(A. H) ÷ n(S)

P(A. H) = (60/150) = (2/5) = 0.40

In Spanish/En español

Pregunta completa y correcta

Con base en los datos de la tabla, encuentre la probabilidad de que una persona con hidratación adecuada pueda completar una carrera de 5 km.

Número de personas que completan el curso.

Situaciones | A. H | I. H | Total

Practicar deportes | 50 20 | 70

No hacer deporte | 10 | 70 80

Total | 60 | 90 | 150

Tenga en cuenta que A. H significa hidratación adecuada e I. H significa hidratación inadecuada.

Solución

La probabilidad de un evento se expresa como el número de elementos en ese evento dividido por el número de elementos en el espacio muestral.

Matemáticamente,

P(E) = n(E) ÷ n(S)

Entonces, para esta pregunta, la probabilidad de que una persona con hidratación adecuada complete el curso = P (A. H)

n (A. H) = Número de personas que tienen una hidratación adecuada y completan el curso = 50 + 10 = 60

n (S) = Número total de personas que completaron el curso = 150

P(A. H) = n(A. H) ÷ n(S)

P(A. H) = (60/150) = (2/5) = 0.40

Hope this Helps!!!!

What is the image of (9,3) after a dilation by a scale factor of 3 centered at the<br> origin?
sergiy2304 [10]

Answer:  (27, 9)

Multiply the original coordinates by the scale factor 3 to get this answer

9*3 = 27

3*3 = 9

This only works if the center of dilation is the origin.

The general rule is (x,y) \to (kx, ky) where k is the scale factor.
