Anybody me this is so hard that not even i can't solve this i don't pay attention in class

Step-by-step explanation:

Given:

bisects angle BAC

Triangle ABC is isosceles triangle, because Angles adjacent to the base of isosceles triangle ABC are congruent.

Hence,

The sum of the measures of all interior angles is 180°, so,

Since bisects angle BAC, angles BAD and CAD are congruent by definition of angle bisector. So,

AD ia angle bisector in isosceles triangle drawn to the base, so it is the height. Thus, AD and BC are perpendicular. So,

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;

answer: what statements

step-by-step explanation if you write the statements down then i could you.
