Suppose that a company claims that its chocolate bars weigh 2.8 ounces on
average. It took many large samples, and each time the mean weight of the
sample was within the 95% confidence interval. Which of the following would
be a reasonable conclusion?

A. The company's chocolate bars do not weigh 2.8 ounces on
average.

B. The company's chocolate bars weigh 2.8 ounces on average.

C. The company's chocolate bars weigh fewer than 2.8 ounces on
average

D. The company's chocolate bars weigh more than 2.8 ounces on
average

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12

step-by-step explanation:

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft
