BD is the angle bisector of ZABC. If m ABD=25° find m/DBC.

A:50°

B:25°

C:750

D:100°

B:25°

Step-by-step explanation:

Now gets bisected by .

Since, the angle is bisected, this means that the angle is split into two equal parts or the angle is halved.

We know that one of the angles is so the other angle has to be also.

Hence, the .

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;
