Answer:
The first one is a reflection of the figure shown over the given line reflection.
For a known standard deviation, the confidence interval for sample size = n is

where
x = average
n = sample size

= stad. deviation
z = contant that reflects confidence interval
Let a = x
Let b =

From the given information,
a - b = 0.432 (1)
a + b = 0.52 (2)
Add (1) and (2): 2a = 0.952 => a = 0.476
Subtract (2) from (1): -2b = -0.088 => b = 0.044
Therefore, the confidence interval may be written as
(0.476 - 0.044, 0.476 + 0.044), or as
(0.476

0.044)
Answer:
y=4x/3+9/3
Step-by-step explanation:
slop is 4x/3
and the point is 3,6
so y-6 = 4x/3(x-3)
sove the you will have y=4x/3+9/3
