Answer:
sample size n would be 149305 large
Value of n (149305) is too high, this will be the practical problem with attempting to find this confidence interval
Step-by-step explanation:
Given that;
standard deviation α = 150 min
confidence interval = 99%
since; p( -2.576 < z < 2.576) = 0.99
so z-value for 99% CI is 2.576
E = 1 minutes
Therefore
n = [(z × α) / E ]²
so we substitute
n = [(2.576 × 150) / 1 ]²
n = [ 386.4 ]²
n = 149304.96 ≈ 149305
Therefore sample size would be 149305 large
Value of n is too high, that would be the practical problem with attempting to find this confidence interval
Answer:
B
Step-by-step explanation:
Given
9² × (
)² - 9
= 81 × 
- 9 ← cancel 81 and 9 by 9 leaving
= 9 - 9
= 0 → B
Answer:
its blurry
Step-by-step explanation:
Answer:
(x, y) = (7, 3)
Step-by-step explanation:
The solution is the point where the lines cross. The coordinates of that point are ...
(x, y) = (7, 3)
Both are linear because they're on the format of y=mx+b. m= slope and b= the y-intercept
