What is the value of s to the nearest whole number? !

14

Step-by-step explanation:

Using the law of cosines on ΔRST, then

s² = 9² + 8² - (2 × 9 × 8 × cos111° )

   = 81 + 64 - ( 144 × cos111° )

   = 145 - (- 51.6)

   = 145 + 51 . 6 = 196.6 ( take the square root of both sides )

s = ≈ 14

The answer is: 14

Using the law of cosines and the given information, we can find the value of s.

Law of cosines is:

Where,

By substituting we have:

So, the correct answer is:

Have a nice day!

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;

no
