She will always have a 25% chance of drawing a specific suit, a 50% for a specific color, a 7.69230769% chance for a specific number or letter, and a 1.92307692% chance of getting a specific card.

Answer with explanation:

Number of cards in the deck = 52=13 club + 13 Heart +13 Diamond +13 Spade

Probability of drawing a Club Card,or a Heart,or a Diamond or a Spade ,from a pack of 52 Cards

      =\frac{_{1}^{13}\textrm{C}}{_{1}^{52}\textrm{C}}=\frac{13}{52}\\\\=\frac{1}{4}

So, Percentage of Drawing a Club Card,or a Heart,or a Diamond or a Spade ,from a pack of 52 Cards

             =\frac{1}{4}\times 100=25

        = 25 %

Probability of drawing, a Red Card or a Black Card from the deck of 52 cards

           =\frac{_{1}^{26}\textrm{C}}{_{1}^{52}\textrm{C}}=\frac{26}{52}\\\\=\frac{1}{2}

So, Percentage of Drawing,a Red Card or a Black Card from the deck of 52 cards

           =\frac{1}{2}\times 100=50

      = 50 %

Now, probability of drawing a card from the deck of 52 cards ,300 times with replacement

              =\frac{1}{52}\times \frac{1}{52}\times \frac{1}{52}\times \frac{1}{52}\times ......300 times\\\\=[\frac{1}{52}]^{300}

Brilliant_brown [7]

Answer:

A=20,000 m2 per year

Step-by-step explanation:

we have that Volume (V) =300,000 m3, so V=A*h, where A=area (m2) and h=15m

V=A*h ⇒ 300,000m3=A*15m ⇒ A=300,000m3/15m ⇒ A=20,000 m2

Question 15: (5 points)
Svetradugi [14.3K]

Answer:

(4,7)

Step-by-step explanation:

Given

2x - 3 < y

(x,7)

Required

Find one possible value of x

From the given parameters;

(x,7) is a possible solution of 2x - 3 < y where y= 7

Substitute 7 for y

2x - 3 < 7

Add 3 to both sides

2x - 3 + 3 < 7 + 3

2x < 10

Divide both sides by 2

2x/2 < 10/2

x < 5

The result of the inequality implies that x is less than 5; So, the possible values of x is all real numbers less than 5;

Having said that;

(4,7) is one possible coordinate of 2x - 3 < y

Solve the following system. x2 + y 2= 25 2x + y = 10 The solution set
anzhelika [568]

Answer: {(5,0), (3,4)}

Step-by-step explanation:

You can apply the Substitution method:

- Solve for y from the second equation.

- Substitute into the first equation and solve for x.

Then:

y=10-2x

x^2+y^2=25\\x^2+(10-2x)^2=25\\

(Remember that: (a\±b)^2=a^2\±2ab+b^2)

x^2+(10^2-2(10)(2x)+(2x)^2)=25\\x^2+100-40x+4x^2=25\\5x^2-40x+75=0\\x^2-8x+15=0\\(x-5)(x-3)=0\\\\x=5\\x=3

Substitute the values obtained into one of the original equation and solve for y:

2(5)+y=10\\10+y=10\\y=0\\\\2(3)+y=10\\6+y=10\\y=4

The solution set is: {(5,0), (3,4)}
