Juno calculated the area of a square to be 4/9 square yard. Which shows the side length of the square?

1 answer:

3 0

$\bf \textit{area of a square}\\\\
A=s^2~~
\begin{cases}
s=side's~length\\
--------\\
A=\frac{4}{9}
\end{cases}\implies \cfrac{4}{9}=s^2
\\\\\\
\sqrt{\cfrac{4}{9}}=s\implies \cfrac{\sqrt{4}}{\sqrt{9}}=s\implies \cfrac{2}{3}=s$

Two cards are drawn without replacement from a standard deck of cards. What is the probability that the second one is a black ca

forsale [732]

Answer:

The probability is 169/2652

Step-by-step explanation:

The number of cards in a deck of cards is 52

In each deck of cards, there are 13 black cards and 13 spade cards

The probability of selecting a spade card will be;

13/52 = 1/4

Without replacement, we are left with 51 cards and the probability of selecting a black card will now be 13/51

So the probability of the second card being a black card if the first is spade will be ;

13/52 * 13/51

= 169/2,652

Answer:

$\displaystyle (0, -1); maximum$

Step-by-step explanation:

First off, B is zero, so there is no phase shift, meaning that the vertex stays on the y-axis. Next, A is negative, so the parabola opens down, and whenever you have a parabola opening down, it does so at maximum. Finally, C represents our y-intercept, or in this case, our vertical shift. Our y-intercept is (0, −1), and so as our vertex, hence our answer.
