Answer:

Step-by-step explanation:

Total number of students =100

Number who bought pop corn = 62

Number who bought drinks = 47

Number who bought both =38

Hence number who did not purchase anything = 100-(62+47-38)

=29

Prob that students buys a drink = 47/100 = 0.47

PROB THAT THE  student buys a drink/he purchsaed pop corn

= Number for both/number of pop corn

=38/62 =0.613

P(buying pop corn) = 0.62 and P(drink) = 0.47

Product of these = 0.62*0.37=0.2356

Thus we find product is not equal to Prob of purchsing both

Hence cannot be independent

The circumference of the hub cap of a tire is 83.21 centimeters. Find the area of this hub cap. Use
Elena L [17]

Answer:

<u>551 square centimeters</u>

Step-by-step explanation:

Finding the radius (r) :

  • C = 2πr
  • 83.21 = 2 x 3.14 x r
  • 83.21 = 6.28r
  • r = 83.21/6.28
  • r = 13.25 cm

Finding the area :

  • A = πr²
  • A = 3.14 x (13.25)²
  • A = 3.14 x 175.5625
  • A = <u>551 square centimeters</u> (nearest whole number)

<u></u>

The area of this hub cap is about <u>551 square centimeters</u>.
