Answer is C. 1/169
first we find how many cards are jacks in a deck: 4 out of 52 cards.
4/52 = 1/13 ( We have a 1 in 13 chance of drawing a jack)
(1/13)(1/13) = 1/169
( because the first card is replaced, we know that we don't have to change probabilities)(it will still be a 4/52 chance of drawing a jack)
Answer: 18x2 + 69x + 65
Step-by-step explanation:
(3x + 5) (~6x + 13)
1. 3x(6x + 13) + 5(6x + 13)
2. 18x2 + 39x + 5(6x + 13)
3. 18x2 + 39x + 30 + 65
4. 18x2 + 69 + 65
Answer:
257
Step-by-step explanation:
The divisors of 72 which are composite number are
4,6,8,9,12,18,36,72 (composite numbers are those numbers which are formed by the multiplication of two whole numbers}
So the total number of divisors which are composite are = 8
So total number of subset 
In question it is said that also include empty set in count
So total number of subset =256+1=257
X+y=4
2x+y=6
make first equation negative
-x-y=-4
add to first equation
2x-x+y-y=6-4
x=2
subsitute
x+y=4
2+y=4
y=2
or
x+y=4
subtract x from both sdies
y=4-x
subsitute 4-x for y in second equation
2x+4-x=6
x+4=6
x=2
