What is the measurement of 0? 4 cm e 12cm o A. 4 radians o B. 3s radians o C. 3 radians o D. 4 radians

Option (c).

The angle is given by 3 radian.

Step-by-step explanation:

Arc length = 12 cm

radius = 4 cm

The relation between the angle and the radius is

Option (c) is correct.  

idk

step-by-step explanation:

maybe try   if it is work from a book, if not try

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;
