Answer: 126
Step-by-step explanation:
As per given , we have
Prior Population proportion :
Significance level :
Critical value for 95% confidence interval (using the z-value table) =
Margin of error (maximum error):
Formula to find the sample size :
Therefore , the required minimum sample size = 126
Answer:
y = -12
Step-by-step explanation:
-4 (8+3y) = 112
-32 -12y = 112
-12y = 144
y = -12
Answer:
y=1/2x+5
Step-by-step explanation:
Plug it into the formula for a point and a slope.
(y-(y(subscript 1)))=(m)(x-(x(subscript 1)))
Y-8=1/2(x-6)
Then multiply the 1/2 to the x and -6. After you do that, move everything so that it has y by itself on the left. Your ending should be y=1/2x+5.
