The area of an 13-cm-wide rectangle is 286 cm^2. What is its length? 20 points and brainliest to whoever has the correct answer in the next 2 hours

L = 22 cm

Step-by-step explanation:

Area of a triangle = L x W

where W = 13 cm

Area = 286 cm²

A = L x W

286 = L x 13

L = 286 / 13

L = 22 cm

proof:

286 = 22 x 13

286 = 286 --- ok

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
