Ben and Carmella want to go to a basketball game. Carmella proposes they use a bag of 90 lettered tiles to decide who will pay f

or the tickets. Of the tiles, 35 are vowels and the rest are consonants. She will blindfold Ben and ask to him randomly choose a tile. If Ben picks a vowel, Carmella will pay for the tickets. If Ben picks a consonant, he will pay for the tickets.
Carmella distributes the 90 tiles into two boxes that are located to the left and to right of Ben. She tells Ben that there are a total of 43 lettered tiles in the box on his left, and 43 of the tiles in the box on his right are consonant tiles. Carmella gives Ben three options of how to select his tile.

Method 1: choose randomly from the box on his right

Method 2: choose randomly from the box on his left

Method 3: mix the letter tiles back together, and choose randomly from the entire set of tiles

Use this information to complete the statement.

The probability that Carmella will pay for the tickets is greatest, approximately __%, if Ben selects his tile using method __.

In the diagram, the circle will be dilated by a scale factor of 3 about the origin. The points C, A, and B map to C', A', and B'
stellarik [79]
Original coordinates of the points:
A (8,15) ; B (12,13) ; C (8,10)

Dilated scale factor of 3.

A ⇒ 3x = 3(8) = 24 ; 3y = 3(15) = 45 ⇒ A' (24,45)
B ⇒ 3x = 3(12) = 36 ; 3y = 3(13) = 39 ⇒ B' (36, 39)
C ⇒ 3x = 3(8) = 24 ; 3y = 3(10) = 30 ⇒ C' (24, 30)

The given image forms a right triangle. So, I'll get the short leg and long leg of the right triangle to solve for the hypotenuse, length of CB.

Short leg: y value of B and C
39 - 30 = 9

Long leg: x value of B and C
36 - 24 = 12

a² + b² = c²
9² + 12² = c²
81 + 144 = c²
225 = c²
√225 = √c²
15 = c

The length of CB is 15 units.

The vertex form of the equation of a parabola is y=2(x+4)^2-7. What is the standard form of the equation.
Elan Coil [88]

Answer:


Step-by-step explanation:

To obtain the standard form of the equation of the parabola y=2(x+4)^2-7, first perform the indicated operations:

y = 2[x^2 + 8x + 16 - 7], or

y = 2[x^2 + 8x + 9],

or y = 2x^2 + 16x + 18

None of the given possible answers match.  The fourth one, D, is closest to the above result, differing only in the constant term (25 versus 18).

Landon is a maintenance worker at an amusement park. He stands atop a raised platform of the park's most popular
Helga [31]

Answer:

the equation fits the situation, but the table doesn’t.

Step-by-step explanation:

For both functions, the lead roller coaster car starts at an initial height of 32 feet. This is the point (0,32), directly above Landon.

The car races past Landon’s field of vision (y = 0) after it moves a horizontal distance of 4 feet and then 8 feet with respect to the starting point. So, the correct function will have x-intercepts of 4 and 8.

Begin by checking the equation. Rewrite the equation in factored form:

f(x) = x^{3} − 11x^{2} + 20x + 32

= (x + 1)(x^{2} − 12x + 32)

= (x + 1)(x − 4)(x − 8)

The equation has x-intercepts of 4 and 8.

But the table only has one x-intercept, located at (4,0). The point (8,160) is well out of Landon’s line of sight.

So, the equation fits the situation, but the table doesn’t.
