Answer:
0.8413
Step-by-step explanation:
Find the z score.
z = (x − μ) / σ
z = (992 − 999) / 7
z = -1
Use a chart or calculator to find the probability.
P(Z > -1)
= 1 − P(Z < -1)
= 1 − 0.1587
= 0.8413
Answer:
Arithmetic sequence
Step-by-step explanation:
We are given that a sequence
14,11,8,5,...
We have to identify sequence as arithmetic or geometric and write explicit formula for the sequence.
When the difference of consecutive terms is constant then the sequence is arithmetic sequence.
Hence, the sequence is an arithmetic sequence.
substitute the values then we get
Then, the explicit formula is given by
