The diameter of a human hair is 9x10^-5 meters. the diameter of a spider's silk is 3x10^-6 meters. how much greater is the diameter of a human hair than the diameter of a spider's silk? write your answer in scientific notation.

3×10¹

Step-by-step explanation:

(9×10⁻⁵ m) / (3×10⁻⁶ m)

(9/3) (10⁻⁵ / 10⁻⁶)

3×10¹

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

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
