Answer:
The common ratio r = 2.
Step-by-step explanation:
Now s2 = a1r and s4 = a1r^3 where a1 = first term and r = common ratio so
s4 / s2 = a1r^3 / a1r = r^2 = 32/8
r^2 = 4
r = 2.
Answer:
y=4/3x+15 1/3 (or) y=4/3x+46/3
Step-by-step explanation:
If it’s parallel, it has to have the same slope (4/3).
Plug 7 in for x, and then find out what you have to do to make y equal -6.
y=4/3x+15 1/3 (or) y=4/3x+46/3
Assuming that the probability of boys and girls is equal (in reality slightly more boys than girls are born), the probability is 1/2, simply because the older girl's gender is given and therefore not a part of the probability.
This question comes from the 'boy or girl paradox', a.k.a. the Mrs Smith Problem.
