Amy sells magazine subscriptions door-to-door. Her earnings in dollars can be found by using the function f (x) = 5.52 + 10, where x is the number of subscriptions sold. If she sold at least 6 subscriptions but not more than 11 subscriptions in a day, state a reasonable domain and range of the function for this situation

the discriminant is 64 + 4*1*12 = 112

this is prime.

the true ones are a b and d

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

a)(x-2)^2+(y-1)^2=9
