Answer:

The probability is [tex]0.3819[/tex]

Step-by-step explanation:

We know that Teresa is playing a game in which she is dealt 8 cards from a deck that includes 3 jokers and 52 common cards (a total of 55 cards).

Let's define the following random variable :

[tex]X[/tex] : '' Number of jokers in the hand of Teresa ''

We need to find [tex]P(X\geq 1)[/tex]

This probability is equivalent to :

[tex]P(X\geq 1)=1-P(X=0)[/tex]

[tex]P(X=0)[/tex] is the probability of having none jokers in the 8 card hand.

In order to find [tex]P(X=0)[/tex] we are going to count all the cases in which [tex]X=0[/tex] (given that we are in presence of an equally - likely sample space)

We calculate [tex]P(X=0)[/tex] as :

[tex]P(X=0)=\frac{\left(\begin{array}{c}52&8\end{array}\right)\left(\begin{array}{c}3&0\end{array}\right)}{\left(\begin{array}{c}55&8\end{array}\right)}[/tex]

We define the combinatorial number [tex]nCr=\left(\begin{array}{c}n&r\end{array}\right)=\frac{n!}{r!(n-r)!}[/tex]

In the denominator we have [tex]\left(\begin{array}{c}55&8\end{array}\right)[/tex] which represents all the ways in which we can extract 8 cards from the deck of 55 cards.

In the numerator we have the product of [tex]\left(\begin{array}{c}52&8\end{array}\right)[/tex]  (which represents all the ways in which we can choose 8 cards from the 52 common cards) and   [tex]\left(\begin{array}{c}3&0\end{array}\right)[/tex]  (which represents that from the total of 3 jokers we extract 0)

 If we perform the operation we find that :

[tex]P(X=0)=0.6181[/tex]

Finally,

[tex]P(X\geq 1)=1-P(X=0)=1-0.6181=0.3819[/tex]

The probability is [tex]0.3819[/tex]

Answer: $2.50

Step-by-step explanation:

The following payments are made by Dustin's Lawn Care Service Customer

Mrs. Schmitt = $15.75

Mr. Jones = $9.25

Mrs. Adams = $22.50

Mr. Meyer = $50.00

To get our answer, we need to add all the payments of the other three. This will be:

= $15.75 + $9.25 + $22.50

= $47.50

The answer will now be:

= $50.0 - $47.5

= $2.50

Answer:

194 yards

Step-by-step explanation:

Perimeter of the proposed parking lot

= 52 + 40 + 20 + (40 - x) + 24 + 10 + (52 - 20 - 24) + x

= 112 + (40 - x + x) + 34 + (52 - 44)

= 146 + 40 + 8

Answer:

Daria bought 11 refills of lemonade last month

Step-by-step explanation:

The equation is:

y = 2x + 9

The cup costs 9 dollars and is 2 dollars per refill

She spent 31 dollars so:

31 = 2x +9

Now we can solve!

2x + 9 = 31

Subtract 9 from both sides!

2x = 22

Divide both sides by 2!

x = 11

We know x is the amount of refills so,

Answer:

graph d because it starst out slower and then ends off faster

The graph that correctly represents the given case is B.

The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.

The negative slope indicates the rate of decrease while the positive shows the rate of increase.

All the graphs are examined one by one as follows,

(A) In the graph A, The slope is negative.

Which implies the the speed will slow down.

(B) In the graph B, The slope is positive.

Which implies the the speed will rise up.

(C) ) In the graph C, The slope is zero.

Which implies the the speed will be constant.

(D)  In the graph D, The slope is positive and it has a y intercept.

Which implies the the speed will rise from a non zero value.

Thus, in order to download a large file the suitable graph is (B).

Hence, the given case can be represented by graph B.

Answer:

15.

explaination:

let x be the number which we have to times to the ratio.

(5+x) + (6+x) =33

5x + 6x =33

11x = 33

x=3

so we need to times 3 the ratio to get the actual number.

boys: 5 × 3 =15

girls:6 × 3 = 18

checking the answer: 15+ 18 = 33

Answer:

If f(1)=0 then 1 is a root and (x-1) is a factor of f(x). divide f(x) by (x-1). you now have a quadratic. Find its roots by methods you know.  

actually this factors by grouping:

f(x)=x³+3x²-x-3

= x²(x+3)-1(x+3)

=(x+3)(x²-1)

=(x+3)(x-1)(x+1) // difference of squares

By zero product property roots are

Answer:

14

Step-by-step explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(8 + 20) / (5 - 3)

28 / 2

= 14

So, the slope is 14.

Answer:

x = 0

Step-by-step explanation:

5(x - 3) + 4(x + 3) = 3(x - 1)

5x - 15 + 4x + 12 = 3x - 3

5x + 4x + 12 - 15 = 3x - 3

9x - 3 = 3x - 3

9x = 3x - 3 + 3

9x = 3x

9x - 3x = 3x - 3x

6x = 0

6x ÷ 6 = 0 ÷ 6

x = 0

Answer:

5( x− 3 ) + 4 ( x +3)

9x − 3 = 3(x− 1 ) Simplify  3 ( x − 1 ) .

9 x − 3 = 3 x − 3

Move all terms containing  x  to the left side of the equation.

6 x − 3 = −3

Move all terms not containing  x

to the right side of the equation.

6 x = 0

Divide each term by  6  and simplify.

x = 0

Answer:

y = 1

Step-by-step explanation:

Since the line never crosses the x-axis, the equation just looks like this: y = 1, because 1 is where the line crosses the y-axis.

Answer:

The length of the flight of stairs is 52 m

Step-by-step explanation:

In parallelograms, opposite sides are equal in length

In the given figure

∵ The building is built in the shape of a parallelogram

∵ The length of the flight of stairs is one side of it

→ We can find it by finding the hypotenuse of the right triangle

   whose legs are 47 m and 22 m

∴ The length of it = the length of the hypotenuse of the right Δ

→ By using the Pythagoras Theorem

∵ h = [tex]\sqrt{(leg1)^{2}+(leg2)^{2}}[/tex]

∵ leg1 = 47 and leg2 = 22  

∴ h = [tex]\sqrt{(47)^{2}+(22)^{2}}[/tex]

∴ h = [tex]\sqrt{2209+484}[/tex]

∴ h = [tex]\sqrt{2693}[/tex]

∴ h = 51.89412298

∵ h represents the length of the flight of stairs

∴ The length of the flight of stairs = 51.89412298 m

→ Round it to the nearest meter

∴ The length of the flight of stairs = 52 m
