La pregunta está incompleta:
Observa los puntajes de las respuestas de una evaluación que tuvo de 100 preguntas. Si Alfredo contestó correctamente 57 preguntas, 16 incorrectas y el resto las dejó en blanco, ¿qué puntuación obtuvo en la evaluación?
Puntos por respuesta:
Correctas: 4
En blanco: -1
Incorrectas: -3
Answer:
Alfredo obtuvo una puntuación de 153.
Step-by-step explanation:
De acuerdo a la información proporcionada, conoces el número de preguntas en la evaluación y el número de preguntas que Alfredo contestó de forma correcta e incorrecta y tienes que restar estas del total de preguntas para encontrar el número de preguntas que dejó en blanco:
100-57-16=27
Ahora, debes multiplicar el número de respuestas correctas, incorrectas y en blanco por su respectivo puntaje:
Correctas: 57*4=228
En blanco: 27*(-1)=-27
Incorrectas: 16*(-3)=-48
Finalmente, debes sumar los resultados obtenidos por cada tipo de respuesta:
228+(-27)+(-48)= 228-27-48=153
De acuerdo a esto, la respuesta es que Alfredo obtuvo una puntuación de 153.
Answer:
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
Step-by-step explanation:
A box plot has 5 data descriptions. The correct option is 87 and 132.
<h3>How does a boxplot show the data points?</h3>
A box plot has 5 data descriptions.
- The leftmost whisker shows the minimum value in the data.
- The rightmost whisker shows the maximum value in the data.
- The leftmost line in the box shows the first quartile.
- The middle line shows the median, also called the second quartile.
- The last line of the box shows the third quartile.
Since each quartile of the box-and-whisker plot represents 25% of the data. Therefore, values between which there are 3 quartiles present will represent 75% of the data.
Hence, the correct option is 87 and 132.

If he ate 6/8 of the pizza, that means 2/8 is left.
2/8 simplify it, by dividing it by 2 and your answer is...
IT'S 1/4
Okay
We know
Height= 32
Diagonal = 60
We Also know a television screen is either a square or rectangle no matter which one, they both can be divided to two triangles. The diagonal remains the same for both triangles and actually all sides has the same measures in both triangles.
Lets use the famous pythagoras formula
K^2+ K ^2 = H^2
So the first K is the Height = 32
The second K we want to find out so it is just K
H will be the Diagonal
So again 32^2+ K^2= 62^2
Now we can solve by
Sorting
1024+ K^2 = 3600
We write the Height and Diagonal as wholenumbers by multiplying 32 with 32 and 60 with 60. 32*32= 1024 and 60*60 = 3600
Now we want K alone
1024 +K^2-1024= 3600-1024
K^2 = 2576
K is still squared we want just K. So Lets find the square root of K. As we say K^2 is the same as 2576 we want to know the square root 2576. That where our answer is
2576 square root= 50,754
So our answer must be 51 inch.
We rounded 50,75 up to 51. This is because The 0,7 has shorter distance to become a 1 than to become a Zero. It has only 0,3 to become 1 while 0,7 to become 0
