Answer:
There are 52 cards in a deck. The total number of outcomes possible when picking 2 cards and replacing them is 52 * 52 = 2704.
There are 4 10s and 4 aces so the total number of successful outcomes = 4 * 4 = 16.
Probability = 16 / 2704 = 1 / 169

Answer:
-2b(k²-3k+1)
Step-by-step explanation:
<u>The question is on factorization</u>
-2bk²+6bk-2b
<u>Factor out 2b</u>
-2b(k²-3k+1)
<u>When you open brackets to check the answer</u>
-2b×k²-2b×-3k-2b×1= -2bk²+6bk+2b
Answer:
25.12
Step-by-step explanation:
The formula of the circumference of a circle is: C = 2(pi)(r)
Plug in 3.14 for pi and 4 for the radius.
C = 2(3.14)(4)
Multiply.
C = 25.12
