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>

Mrs.Bennett has graded 20% of her 150 students papers. How many papers does she still need to finish?
Fynjy0 [20]
If she has finished 20%, she still has 80% to do. So just calculate .8 times 150.

4) What percent of 141.9 is 83?<br> A) 0.01%<br> B) 0.49%<br> C) 202.4%<br> stills D) 58.5%
Veseljchak [2.6K]

Answer:

D) 58.5%

Step-by-step explanation:

We can rule out A,B, and C becuase they are absurd answers.

A is wrong because just 1% is 1.41.

B is wrong because of A's explanation

C is wrong because over 100% of a number is greater than the initial number

58.5% just by intuition can be seen as the answer that makes the most sense.

give brainliest please!
hope this helps :)
