Equation of a line intersecting at -3 on x axis and 3 y axis

Step-by-step explanation:

hello :

an equation is : y=ax+b

a line intersecting at -3 on x :  when x=-3    y=0 means : 0=a(-3)+b ...(*)

a line intersecting at 3 on y axis :   when x=0    y=3 means : 3 = a(0)+b(**)

by (**) : b=3   put this value in (*) :  0 = -3a+3   so a= 1

an equation is : y = x+3

a. 19,958,400

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
