In a lottery game, a player picks 9 numbers from 1 to 46. If 8 of the 9 numbers match those drawn, the player wins second prize. What is the probability of winning this prize? Be sure to leave your answer as a reduced fraction in order to earn credit.

There is a _____
probability of winning second prize.

Answers

Answer 1

Answer:  [tex]\frac{37}{1,101,716,330}\\\\[/tex]

This is the same as writing 37/1101716330

======================================================

Explanation:

Let's say the nine winning numbers are: 1,2,3,4,5,6,7,8,9

Let's further say that if we matched everything from 1 to 8, then we'll win second prize. That ninth value can be anything but 9. So we could have something like one of these examples

1,2,3,4,5,6,7,8,101,2,3,4,5,6,7,8,111,2,3,4,5,6,7,8,12

As you can see, there are 46-9 = 37 different choices we can have for that last slot. In other words, there are 37 items in the set {10,11,12,...,45,46} we can pick for that last ninth slot. Note that 46-10+1 = 37. This value will form the numerator of the answer.

------------------------------------------

Now to calculate how many ways there are to select the nine values regardless if we win or lose.

Since order doesn't matter, we use the nCr combination formula.

[tex]_{n} C _{r} = \frac{n!}{r!*(n-r)!}\\\\_{46} C _{9} = \frac{46!}{9!*(46-9)!}\\\\_{46} C _{9} = \frac{46!}{9!*37!}\\\\_{46} C _{9} = \frac{46*45*44*43*42*41*40*39*38*37!}{9!*37!}\\\\[/tex]

[tex]_{46} C _{9} = \frac{46*45*44*43*42*41*40*39*38}{9!} \ \text{ ... the ``37!'' terms cancel}\\\\_{46} C _{9} = \frac{46*45*44*43*42*41*40*39*38}{9*8*7*6*5*4*3*2*1}\\\\_{46} C _{9} = \frac{399,790,821,830,400}{362,880}\\\\_{46} C _{9} = 1,101,716,330\\\\[/tex]

There are slightly over 1 billion ways to select the nine values.

This large value is the denominator of our answer which is [tex]\frac{37}{1,101,716,330}\\\\[/tex]

The 37 up top represents the number of ways to win the second prize we're after, while the massive number in the denominator represents how many ways there are to play the game.

------------------------------------------

Notice that in the jump from step 4 to step 5, shown in the section above, we had the "37!" terms cancel out. What this means is that the prime number 37 is nowhere to be found anywhere in the factorization of 1,101,716,330

Why is this important? Because it tells us that the fraction [tex]\frac{37}{1,101,716,330}\\\\[/tex] cannot be reduced.

Side note: That fraction converts to the decimal form 0.00000003358397 approximately and that converts to the percentage form 0.000003358397%; both of which are very very small numbers. We can see that the odds are definitely stacked against the player.

of the barn, how much space does Snoopy have to roam?
Use pi = 3.14 and round your answer to the nearest tenth.

Answers

Answer:

A   = 981.3 ft^2

Step-by-step explanation:

Here we're calculating the area of a semicircle of radius 25 ft.

The area of a circle is A = (pi)(r)^2, and that of a semicircle of the same radius is A = (1/2)(pi)(r)^2.

Here pi = 3.14 and r = 25 ft, and so the area/space in question is

A = (1/2)(3.14)(25)^2

A   = 981.3 ft^2

The space does Snoopy have to roam is 490.625 square feet.

Given that, Snoopy the dog is on a 25-ft long chain that is attached to the back of a barn.

What is the area of a sector?

The area of a sector is the space inside the section of the circle created by two radii and an arc. It is a fraction of the area of the entire circle.

The formula for the area of the sector of a circle is /360° (r²) where r is the radius of the circle and is the angle of the sector.

From the attached image, we see that snoopy is at the edge of a circle with the garage taking up a quarter of that circle.

Now, the area of space Snoopy was roaming

= 90°/360° × (3.14 × 25²)

= 1/4 × (3.14 × 625)

= 0.25 × 1,962.5

= 490.625 square feet

Therefore, the space does Snoopy have to roam is 490.625 square feet.

The path of a skateboarder can be modeled by the equation (x – 3)2 = –4(y – 9), where distance is in feet and air resistance is insignificant. If the skateboarder makes a jump from a ramp at x = 0, what is her maximum height and how far is she horizontally from the end of the ramp when she lands?

Answers

Answer:

The correct answer would be: "Maximum height 9 feet; horizontal distance 9 feet".

Step-by-step explanation:

I know this not only because I already took the test, BUT by graphing the equation (you can use graphing apps) it'll give you the answer.

Her maximum height is 9 feet & she is horizontally 9 feet from the end of the ramp when she lands.

What is skateboarders maximum height ?

The path of the skateboarder can be modelled by the equation,

(x-3)² = -4(y-9)

Now, from the equation, solving y,

(x-3)² = -4(y-9)

⇒ y-9 = -[tex]\frac{1}{4}[/tex](x-3)²

⇒ y = -[tex]\frac{1}{4}[/tex](x-3)² + 9

∴ Maximum height is 9 feet.

How far is she horizontally from end of ramp ?

We have to take y = 0,

Now, -[tex]\frac{1}{4}[/tex](x-3)² + 9 = 0

        ⇒ -(x²-6x+9)+36 = 0

        ⇒ -x²+6x-9+36 = 0

        ⇒  x²-6x-27 = 0

        ⇒ x²-9x+3x-27 = 0

        ⇒ (x-9)(x+3) = 0

        ⇒ x = 9 or x = -3

Neglecting the negative value we get, x = 9

So, Her horizontal distance from end of the ramp is 9 feet.

Step-by-step explanation:

y  =2/3x  +  1/3

slope 2/3

y-intercept:   (0  ,1/  3)

Answer:

Step-by-step explanation:

- 2x + 3y = -1​ is the equation of a line

Pick any values for x then find y or for y and then find x;

if you have two points you can draw a line trough those two points.

For example,

pick x= -1 then find y

- 2*(-1) + 3y = -1​

         2+ 3y = -1

              3y = -1-2

                y= -3/3

                y= -1

First point has the coordinates (-1, -1)

pick y = 1 then find x

- 2x + 3*1  = -1​

      -2x +3 = -1

           -2x = -1-3

            -2x = -4

                x= -4/-2

                x= 2

Second point has the coordinate (2, 1)

Draw a line trough the points (-1, -1) and (2,1) to sketch the graph of -2x+3y = -1
