Write an explicit formula for the then find a17

The correct answer option is: .

Step-by-step explanation:

We are given the following arithmetic sequence and we are to write an explicit formula for it and the find the 17th term of the sequence:

{}={}

From the given options, we can put in the values of n and check if it proves to be true.

For  , put values of from 1 to 5 which the number of the term.

Therefore, the formula for the given sequence is  .

Also,

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
