Step-by-step explanation:
Answer:
y = -5/4x - 7
Step-by-step explanation:
First, find the slope:
3 - -7 / -8 - 0 = -5/4
Put it in point slope form:
y + 7 = -5/4(x-0)
y + 7 = -5/4x
y = -5/4x - 7
Answer:
y=2
Step-by-step explanation:
since the line is horizontal, on the point 2 on the y axis, the equation is 2. If, however the line were to be diagonal, it would have been different, as would it if the line were vertical(in which case, the equated would start x =)
Hope this helps
Answer: 0.0241
Step-by-step explanation:
The formula we use to find the margin of error :
, where z* = Critical value , n= Sample size and p = Sample proportion.
As per given , we have
n= 2400
Sample proportion of subjects showed improvement from the treatment:
Critical value for 99% confidence = z*= 2.576 (By z-table)
Now , the margin of error for the 99% confidence interval used to estimate the population proportion. :
[Round to the four decimal places]
Hence, the margin of error for the 99% confidence interval used to estimate the population proportion. =0.0241
