Answer:
95% Confidence interval: (96.06,103.94)
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 85
Sample mean,
= 100
Sample size, n = 30
Alpha, α = 0.05
Population standard deviation, σ = 11
95% Confidence interval:
Putting the values, we get,

Answer:
y= -5/3x-2
Step-by-step explanation:
Answer:
x > 4/33
Step-by-step explanation:
(-4 +8x) +3> x/-4
8x - 1 > x/-4
-32x + 4 < x
4 < 33x
4/33 < x
Hello, again!!
So, the range is the outcome when you plug in any x. In other words, the y.
Because this is absolute value, the x will turn positive. However, the number will then turn negative.
Therefore, y will ALWAYS be negative.
The answer is C.
Hope this helps!! Let me know if you have ANY questions.
