Sami took six quizzes in science class. The grades for the quizzes are 86, 92, 79, 96, 80, and 95. What is the median grade?
mart [117]

Answer:

The median grade would be 89

Step-by-step explanation:

To find the median, first put the numbers all in ascending order.

79, 80, 86, 92, 95, 96

Now isolate the middle term or terms. Since there is an even amount of numbers, we pick the two in the middle. To find the median, we take an average of those terms.

(86 + 92)/2 = 89

Find the equation of the line passing through the points (15,-25) and (-12,11). Write your answer in the form of y=mx+b
schepotkina [342]
(15,-25)(-12,11)
slope = (11 - (-25) / (-12 - 15) = - 36 / 27 which reduces to - 4/3

y = mx + b
slope(m) = -4/3
use either of ur points (15,-25)...x = 15 and y = -25
now we sub and find b, the y int
-25 = -4/3(15) + b
-25 = - 20 + b
-25 + 20 = b
-5 = b

so ur equation is : y = -4/3x - 5 <==
