Student
Ana
Brady
Collin
Deshawn Number of Flips
50
10
80
20
Which student is most likely to find that the actual number of times his or her coin lanc
matches the predicted number of heads-up landings?
Ana

Brady

Collin

Deshawn

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

n=1.75+1.75

step-by-step explanation:

3.5/2=1.75
