<u>(a) Construct a 95% confidence interval for the difference between the average number of intrusion attempts per day before and after the change of firewall setting (assume equal variance)</u>
Use the equation 2πr (so it would be 2π5 or 31.4)
Answer:
Step-by-step explanation:
<u>Two ways to solve</u>
1.) Expand each term in the equation
- 7x = x · x · x · x · x · x · x
- 6x = x · x · x · x · x · x
- Count all the x’s ⇒ There are 13 x’s ⇒ 13x
2.) Add the coefficients
Hence,
Answer = 13x
Answer:
D (last one)
Step-by-step explanation:
(x - 3)(x + 11)
Expand
x² + 11x - 3x - 33
Simplify
x² + 8x - 33
