What would (4,3) be after it is reflected to the y=x

Mathematics

Paul [167]3 years ago

Answer:

(3,4)

Step-by-step explanation:

The amount of steps applied from the reflection line to the point would be also applied inversely to the image point (after reflection).

From y=x to (4,3), it goes 1 down and also goes 1 right. (NOTE: It does not go down and right. Instead, it goes <em>either</em> down and right)

So now inverse that to make 1 up and also going 1 left.

Calificación mínima. Para obtener una A en un curso, Stephen Heasley debe
Snowcat [4.5K]

Answer:

La mínima calificación que Stephen puede recibir en el quinto examen  para obtener una A en el curso es 98.

Step-by-step explanation:

La media (también llamada promedio o media aritmética) de un conjunto de datos es una medida de posición central. Es el valor obtenido al sumar todos los datos y dividir el resultado entre el número total de datos.

En este caso, el número total de datos es 5 y el valor de los datos de los cuales debes obtener el problema es 92, 87, 96, 77 y un valor desconocido de un quinto examen. Y sabes que este valor debe ser igual o mayor a 90.

Esto se expresa matemáticamente como:

\frac{92+87+96+77+nota}{5}≥90

donde "nota" es la mínima calificación que Stephen puede recibir en el quinto examen para obtener una A en el curso.

Resolviendo:

\frac{352+nota}{5}≥90

352+nota≥90*5

352+nota≥450

nota≥450 - 352

nota≥98

<u><em>La mínima calificación que Stephen puede recibir en el quinto examen  para obtener una A en el curso es 98.</em></u>

Eight white balls and twenty black balls are in a bag. What is the probability of drawing a black ball in one draw?
agasfer [191]
Probability is quite simple. In this case, you just need to find the total number of balls (28) and the total number of black balls (20) Now, create a ratio (20/28) Next, simplify it down to 5/7, and that is your answer. I hope that helps! :)
