2.

The expression is also known as , and the expression is also known as . In other words, the numerator of the exponent stays with the variable and the denominator of the exponent goes outside the square root sign.

3. 1/6

I just plugged this into my calculator. The equation for area is A = lw, so by plugging this into your calculator, you get .16666..., which is equal to 1/6

Hope this helps :)

step-by-step explanation:

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
