ANSWER
The six terms for the arithmetic sequence is 1.6, 1.2, 0.8. 0.4, 0, -0.4
EXPLANATION
Given that;
To find the second term, let n = 2
To find the third term, let n = 3
To find the fourth term, let n = 4
To find the fifth term, let n = 5
To find the 6th term, let n = 6
Hence, the six terms for the arithmetic sequence is 1.6, 1.2, 0.8. 0.4, 0, -0.4
Answer:
250
Step-by-step explanation:
Total length of fence = 3,000 ft
additional info
for every 48 ft of fence, there are 4 posts
4 post covers 48 ft of fence
1 post will cover 48/4 ft of fence (dividing both side with four)(48/4 = 12)
=> 1 post will cover 12 ft of fence
Given that the Total length of fence is 3,000 ft
no of post required to cover total length of fence will be
= Total length of fence / length of fence 1 post covers
substituting value of Total length of fence(3000 ft)
and length of fence 1 post covers (12 ft)
we have
no of post required to cover total length of fence will be
= 3000/12
= 250 ------Answer
Answer:
(0.4958, 0.7422)
Step-by-step explanation:
Let p be the true proportion of water specimens that contain detectable levels of lead. The point estimate for p is . The estimated standard deviation is given by . Because we have a large sample, the 90% confidence interval for p is given by where is the value that satisfies that above this and under the standard normal density there is an area of 0.05. So, the confidence interval is , i.e., (0.4958, 0.7422).
