Find the 12th term of the sequence which has a first term of 14 and has a common ratio of 1.03

.

Step-by-step explanation:

Given  : sequence which has a first term of 14 and has a common ratio of 1.03.

To find :Find the 12th term of the sequence .

Solution : We have given first term of 14 and has a common ratio of 1.03.

Sum of n terms ( .

Where, a = first term , r = common ratio and n = number of terms .

Then, Plug the values a = 14 , r = 1.03 , n = 12.

.

.

.

.

Therefore, .

step-by-step explanation:

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;
