If the quality control manager wants to estimate the average life of lamps with 20 hours, with a confidence level of 95% and an error of 10% is assumed. What is the sample size?
The number of ways there are to get to the point (7,4) if you have to pass through the point (2,2) is; 1266 ways
<h3>How to find the lattice Paths?</h3>
The formula to get the number of ways to get to the lattice point (x, y) (supposing x, y ≥ 0) by taking steps of one unit each either in the eastward or northward direction is exactly;
(x + y)
= (x + y)!/(x!y!)
( x )
Thus, number of ways from (0, 0) to (2, 2) = (2 + 2)!/(2!2!) = 6 ways
Number of ways to get to point (7,4) from (2, 2) is;
((7 - 2) + (4 - 2))!/(2!2!) = 7!/(2!2!) = 1260
Thus, total number of ways = 1266 ways

No. Because in both the 6 to the left is 10 times the value of the 6 on the right.
Answer:B. Her mean, median and mode are equal.
Step-by-step explanation:
Mean = (sum of the outcomes)/(total number of outcomes)
Total number of rounds played is 7
The scores for the 7 rounds played are - 6, - 4, - 1 , +3 , - 2, -1, +4
Sum of the scores = - 6 - 4 - 1 + 3 - 2 -1 + 4 = -7
Mean = - 7/7 = - 1
The mode is the most occurring score. Looking at the scores, - 1 occurred twice, so the mode is - 1
The median is the middle score. We would determine it by rearranging the scores in increasing or decreasing order. It becomes
- 6, - 4, - 2, -1, -1, +3, +4
The median is -1
The true statement is
B. Her mean, median and mode are equal.
