What is the length of the missing side of this right triangle?

D. 23.4

Step-by-step explanation:

√(15^2 + 18^2) = ~ 23.4

√(b^2 + a^2) = c

D) 23.4

Step-by-step explanation:

To solve this, use the Pythagorean Theorem: a² + b² = c² where a and b are legs (sides) and c is the hypotenuse (in this case z or the missing side). So, your new equation is: 15² + 18² = z² or 225 + 324 = z². Add 225 + 324 to get 549. To solve for z, find the square root of 549: 23.430749. Rounded to the nearest tenth, this is 23.4.

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
