Answer:
7-2x=y
Step-by-step explanation:
When a point passes through a line it satisfies its equation
(X-x0 )m= y-y0
Slope = m = -2
(X-2 )(-2)=y-3
4-2x=y-3
7-2x=y
Step-by-step explanation:

Answer:
We need a sample of size at least 13.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The margin of error is:

90% confidence interval: (0.438, 0.642).
The proportion estimate is the halfway point of these two bounds. So

95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
Using the information above, what size sample would be necessary if we wanted to estimate the true proportion to within ±0.08 using 95% confidence?
We need a sample of size at least n.
n is found when M = 0.08. So






Rounding up
We need a sample of size at least 13.
1st hen =6x
2nd hen =7y
1st hen is greater than 2nd
so you get 6x > 7y
