2. Harry collects data from a random

sample of seventh-graders. Out of

25 respondents, 10 ride the bus to

school. Of the 150 seventh-graders

who attend Harry's school, how many

would be expected to ride the bus

to school?

A 40 seventh-aradore

60 seventh graders.

Step-by-step explanation:

Harry collects data from a random sample of seventh-graders.

It is given that out of 25 respondents, 10 ride the bus to school.

Probability that the student ride the bus to school is

We need to find the expected number of students out of 150 who ride the bus  o school.

Hence, 60 seventh graders ride the bus to school.

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
