Answer:
33/130
Step-by-step explanation:
3/4 - 1/5 = 11/20
5/2 - 1/3 = 2 and 1/6
11/20 divided by 13/6 = 33/130
She can create 16 because there’s 4 numbers times the 4 digit code, she have 16 different possibilities of #s
Answer:
A
Step-by-step explanation:
Given the solutions of a quadratic, say x = a, x = b then the factors are
(x - a) and (x - b) and the function is the product of the factors, that is
f(x) = (x - a)(x - b)
Here the solutions are x = 5 and x = - 1, thus the factors are
(x - 5) and (x - (- 1)), that is (x - 5) and (x + 1), thus
f(x) = (x - 5)(x + 1) → A
Answer:
P=0.00564
Step-by-step explanation:
From Exercise we have 52 cards.
We calculate the number of combinations to draw 5 cards from a deck of 52 cards. We get
{52}_C_{5}=\frac{52!}{5!(52-5)!}=2598960
We now count the number of favorable combinations:
{13}_C_{1} · {48}_C_{2}= 13 · \frac{48!}{2!(48-2)!}=14664
Therefore, the probabilitiy is
14664/2598960=0.00564
P=0.00564
