Determine whether the study is an experiment or an observational study, and then identify a major problem with the study. in a survey, 1465 internet users chose to respond to this question posted on a newspaper's electronic edition: "is news online as satisfying as print and tv news? " 52% of the respondents said "yes." (a) this is an because the researchers the individuals (b) what is a major problem with the study? a. the sample is not very large. b. this is a convenience sample with voluntary response, which has a high chance of leading to bias c. there is no blinding or replication, which has a high chance of leading to bias. d. the results apply only to internet users.

its very big question plz make it small

1st integer x

2nd integer x+1

3rd integer x+2

4th integer x+3

x+x+1 +x+2+x+3 =74

combine like terms

4x+6 = 74

subtract 6 from each side

4x = 68

x = 17

the integers are 17,18,19,20

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
