Whats up guys i need some help ty :)

37.7in²

Step-by-step explanation:

(Assuming the paper goes around the side of the tin only and not the top/bottom)

Imagine the net of this can. It is a cylinder, so it would consist of a rectangle and two circles, the surface area of this rectangle is what we're being asked for.

The length and width of the rectangle are needed to find the area, (area of a rectangle=length*width). The width is marked as 3in. The length is equal to the circumference of the circle (with radius 2in):

Circumference=2πr

=2π(2)

=12.5663706144=length

Area=width*length

=3*12.5663706144

=37.6991118431

≈37.7in²

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

answer is b
