6x4 would be a numerical expression since a numerical expression uses numbers to recieve a certain mathmatical product. In this case the product would be 24.

Find the probability of winning second prize (that is, picking five of the six winning numbers) with a 6/44 lottery, as played i

WINSTONCH [101]

Answer:

The answer to the question is

The probability of winning second prize (that is, picking five of the six winning numbers) with a 6/44 lottery, as played in Connecticut, Missouri, Oregon, and Virginia is 3.49905×10⁻⁵≡ 0.00003 to five decimal places.

Step-by-step explanation:

The probability of winning the second prize or picking five of the six winning numbers) with a 6/44 lottery is given by

Number of 5 sets of numbers in 44 = ₄₄C₅ = 1086008 ways

Number of 5 set of winning numbers in 44 = 1

Number of ways of picking the last number to make it 6 numbers is given by

44 - 5 lucky numbers - The 1 winning number = 38

Therefore, there are 38 ways from 1086008 of selecting the 5 second place winning numbers

Therefore the probability of picking the 5 second place winning numbers is $\frac{38}{1086008}$ = 3.49905×10⁻⁵

Answer:

ΔABC is a right triangle

length of the concession stand = 42.4 ft (nearest tenth)

Step-by-step explanation:

Given:

Side length of square A = 30 ft
Side length of square B = 40 ft
Side length of square C = 50 ft

We can use Pythagoras' Theorem to prove if ΔABC is a right triangle.

Pythagoras' Theorem: a² + b² = c² (where a and b are the legs, and c is the hypotenuse of a right triangle)

Given:

a = side length of square A = 30
b = side length of square B = 40
c = side length of square C = 50

⇒ a² + b² = c²

⇒ 30² + 40² = 50²

⇒ 900 + 1600 = 2500

⇒ 2500 = 2500

Therefore, ΔABC is a right triangle

To find the diagonal of square A, use Pythagoras' Theorem:

Given:

a = side length of square A = 30
b = side length of square A = 30
c = diagonal of square A

⇒ a² + b² = c²

⇒ 30² + 30² = c²

⇒ 900 + 900 = c²

⇒ c² = 1800

⇒ c = √(1800)

⇒ c = 42.42640687

Therefore, the length of the concession stand (diagonal of square A) is 42.4 ft (nearest tenth)

How do i do this I NEED HELP!!!

Answer:

penny object: 5
quarter object: 10
circle object: 20

Step-by-step explanation:

The first thing to realize is that the penny object is not worth 1, and the quarter object is not worth 25. Once you realize the values are not what they seem, but are consistent throughout, it becomes a different problem than it first appears to be.

___

Let p, q, c represent the values of the penny object, the quarter object, and the circle object, respectively. The trick is to find 3 independent equations describing their values.

The middle two rows of the matrix shown give rise to the equations ...

2p +c +q = 40

p +2c +q = 55

The leftmost column adds a third independent equation ...

p + c + 2q = 45

We can subtract the last equation from the middle one.

(p +2c +q) -(p +c +2q) = 55 -45

c - q = 10 . . . . . simplify . . . [eq4]

And we can subtract the first equation from twice the last one.

2(p +c +2q) -(2p +c +q) = 2(45) -40

c +3q = 50 . . . . simplify . . . [eq5]

Subtracting eq4 from eq5 gives ...

(c +3q) -(c -q) = (50) -(10)

4q = 40 . . . . simplify

q = 10 . . . . . .divide by 4

The eq4 tells us

c = 10 + q = 10 + 10 = 20

and the third equation tells us

p = 45 - 2q - c = 45 -2·10 -20 = 5

The object values are: penny, 5; quarter, 10; circle, 20.
