Answer:
y = 8x + 4
Step-by-step explanation:
combine 1/2 and y:
-4x + y/2 = 2
add 4x to both sides:
+4x -4x + 1/2y = 2 +4x
mutiple both sides by 2 :
2 (y/2) = 2 (2 +4x)
simplify both sides:
y= 8x + 4

Z score = 66 - 76
---------- = - 1
10
from the tables of normal distribution this corresponds to 0.34-3 of the area under the normal curve
so reuired number od students = 0.3413 * 230 = 78
Multiply 4and 25 then get the sq rt of 100 = 10
