If you choose one card from a standard deck, what is the probability that the card is either red or a king?

kherson [118]

$|\Omega|=52\\ |A|=\underbrace{26}_{\text{red}}+\underbrace{4}_{\text{king}}-\underbrace{2}_{\text{red king}}=28\\\\ P(A)=\dfrac{28}{52}=\dfrac{7}{13}\approx54\%$

The linear equality represented by the graph as, $\rm y > \frac{2}{3} x+3$

<h3>What is the definition of inequality?</h3>

Inequality is a sort of equation in which the equal sign is missing. As we will see, inequality is defined as a statement regarding the relative magnitude of two claims.

The slope of the dashed line is found as;

$\rm m = \frac{y_2-y_1}{x_2-x_1} \\\\\ m = \frac{3-1}{0+3} \\\\ m= \frac{2}{3}$

The slope-intercept form is;

y=mx+c

Substitute the obtained value;

$\rm y = \frac{2}{3}x+3$

We are aware that the given line Is a dashed line, and everything to its left is shadowed.

Hence, the linear equality is represented by the graph as, $\rm y > \frac{2}{3} x+3$

Quadrilateral ABCD in the figure below represents a scaled-down model of a walkway around a historic site. Quadrilateral EFGH re

Mkey [24]

the picture in the attached figure

Step 1

Find the perimeter of the scaled-down model of a walkway (Quadrilateral ABCD)

$P=AD+DC+CB+BA\\P=3+2+2+4\\ P=11 in$

Step 2

Find the scale factor

if Quadrilateral ABCD is similar to Quadrilateral EFGH

then

$PerimeterEFGH=PerimeterABCD*scale factor$

$scale.factor=\frac{EF}{AB} \\ \\ scale.factor=\frac{60}{4} \\ \\ scale.factor=15\frac{ft}{in}$

Step 3

Find the perimeter of the actual walkway (Quadrilateral EFGH)

$PerimeterEFGH=PerimeterABCD*scale factor$

$PerimeterEFGH=11*15$

$PerimeterEFGH=165 ft$

therefore

the answer is

$165 ft$
