PLEASE HELP For the past two weeks, Benita has been recording the number of people at Eastside Park at lunchtime. During that time, there were 50 or more people at the park 9 out of 14 days.

a. What is the experimental probability that there will be 50 or more people at the park during lunchtime on the fifteenth day?

b. What is the experimental probability that there will not be 50 or more people at the park during lunchtime on the fifteenth day?​

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

< 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
