Pia printed two maps of a walking trail. the length of the trail on the first map is 8 cm. the length of the trail on the second map is 6 cm. (q. 1) 1 cm on the first map represents 2 km on the actual trail. what is the scale factor from the map to the actual trail? what is the length of the actual trail? (q. 2) a landmark on the first map is a triangle with side lengths of 3 mm, 4 mm, and 5 mm. what is the scale factor from the first map to the second map? what are the side lengths of the landmark on the second map? show your work.

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

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
