Answer:
Step-by-step explanation:
P(2 heads) = P(first flip = head)*P(second flip = head)
=> 
= 
P(1 head) = P(first flip = head)*P(second flip = tail) + P(first flip = tail)*P(second flip = head)
= 
P(no heads) = P(first flip = tail)*P(second flip = tail)
=

Answer:
option A and E
Step-by-step explanation:
Arithmetic sequence converge, only in the case only when r=0
otherwise , arithmetic sequence goes increasing or decreasing at a constant rate.
So we ignore second and fourth option
If |r|<1 then geometric sequence converge
if |r|>1 then geometric sequence diverge
In option A, r= 1/5 that is less than 1 so it converge
In option C, r= -2 , |r| > 1 so geometric sequence diverge
In option E, r= 2/3 that is less than 1 so it converges
Answer is option A and E
Answer:
$308
Step-by-step explanation:
First, you have to find out how much it costs per pound, so you would divide 231 by 21. each pound of potatoes costs $11. so 11 x 28 would make it $308.
34 x 0.07375= 2.5075
2.5075 + 34 =36.51
or
34×1.07375=36.51
Answer:
Step-by-step explanation:
mean- add up all numbers and divide by how many numbers there are
median- the middle number out of the list of numbers
mode- the number you see most often
