Answer:
y=

Step-by-step explanation:
x₁ y₁ m= slope
(2, -4) point-slope equation: y - y₁ = m( x - x₁)
y-(-4) =
( x - 2)
y + 4 =
- 
y =
-
- 
y =
- 
For this type of problem the way to do it is..
1) add the inside of the triangle, in this case it is --> 132 + (2×+4) and then you set it equal to the number that's outside the triangle which is 112
2) and then you solve .... 132+4=136
3) your equation should look like ---> 2×+136=112
4) you subtract 136 from both sides
5) you get 2×= -24
6) divide 2 from both sides.. and you get ×=-12
that's if they are asking for the value of X
if they want to go further... you plug in the value of x in which we found was -12 into the angle above... I hope I helped.

Answer:
95%
Step-by-step explanation:
For a given sample data, the width of the confidence interval would vary directly with the confidence level i.e. more the confidence level, wider will be the confidence interval.
This is because the critical value associated with the confidence level(e.g z value) becomes larger as the confidence level is increased which results in an increased interval.
The confidence interval for a population proportion is given by the formula:

So, for a fixed value of p,q and n, the larger the value of z the wider will be the confidence interval.
Hence 95% confidence interval will be wider than 80% confidence interval.
