10.) Before beginning a unit on frog anatomy, a seventh-grade biology teacher gives each of the 24 students in the class a pre-test to assess their knowledge of frog anatomy. The teacher wants to
compare the effectiveness of an instructional program in which students physically dissect frogs with
the effectiveness of a different program in which students use computer software that only simulates the
dissection of a frog. After completing one of the two programs, students will be given a post-test to
assess their knowledge of frog anatomy. The teacher will then analyze the changes in the test scores
(score on post-test minus score on pre-test).
a. Describe a randomization process for assigning the 24 students to two groups of equal size.

step-by-step explanation:

i think its about 8

answer: 1.06 km per sec

step-by-step explanation:

39.6 m=63.72 km

60 min in an hour so 63.72/60=1.06

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
