Consider a standard deck of 52 playing cards, a randomly selected card from the deck, and the following events: R = red, B = bla

Alika [10]

Answer:

Events D and C are mutually exclusive.

Step-by-step explanation:

Two events D and C are mutually exclusive if

$Pr(D\cup C)=Pr(D)+Pr(C)$

Find these probabilities. In a standard deck of 52 playing cards there are 13 diamond cards and 13 club cards.

The probabilty of chosing diamond is

$Pr(D)=\dfrac{13}{52}=\dfrac{1}{4}$

The probabilty of chosing club is

$Pr(C)=\dfrac{13}{52}=\dfrac{1}{4}$

The probabilty of chosing diamond or club is

$Pr(D\cup C)=\dfrac{13+13}{52}=\dfrac{1}{2}$

Since

$\dfrac{1}{2}=\dfrac{1}{4}+\dfrac{1}{4},$

events D and C are mutually exclusive.

Y^2-2y+1=x+5<br><br> Make y the theme of the formula in the equation

Tanzania [10]

Answer: y = 1 +/- $\sqrt{x+5}$

<u>Step-by-step explanation:</u>

y² - 2y + 1 = x + 5

(y - 1)² = x + 5

$\sqrt{(y-1)^{2}} = \sqrt{x+5}$

y - 1 = +/- $\sqrt{x+5}$

y = 1 +/- $\sqrt{x+5}$

Allison and Megan were at track practice. The track is 3/8 kilometers around.

Ad libitum [116K]

Allison ran 3/8 km (0.375 km) in 3 minutes.

Set up a proportion to find how long it takes for her to run 1 km

$\frac{0.375\textrm{km}}{3 \textrm{min}} = \frac{1\textrm{km}}{x \textrm{min}}$

Cross multiply to get:

$3 = 0.375x$

Solve:

$x = \frac{3}{0.375}$

x = 8 minutes
