The probability is 4⋅3⋅2⋅1/10•9•8•7=(4/4)(6/0)/(10/4)=1/210 so the probability of selecting 3 red balls would be 1/210

<u><em>Answer:</em></u>

y = -x² + 60x + 256 in²

<u><em>Explanation:</em></u>

<u>Before we begin, remember the following:</u>

yᵃ × yᵇ = yᵃ⁺ᵇ

<u>Now, for the given problem:</u>

We know that the area of the rectangle is the product of its dimensions (length and width)

<u>This means that:</u>

Area of rectangle = length × width

<u>Now, we are given that:</u>

length of game board = x+4 in

width of game board = -x+64 in

<u>Substitute with the givens in the rule it as follows: </u>

Area of rectangle = length × width

Area of board game = (x+4)(-x+64)

<u>Use the distributive property, compute the product and gather like terms as follows:</u>

Area of board game = (x+4)(-x+64)

Area of board game = x(-x) + x(64) +4(-x) +4(64)

Area of board game = -x² + 64x - 4x + 256

Area of board game = -x² + 60x + 256 in²

Hope this helps :)

Solve the problem. The formula d = rt gives the distance traveled in time t at rate r. If a bicyclist rides for 2.3 hours and tr
Contact [7]

Answer:

17.83

Step-by-step explanation:

d = r*t

d = 41 miles

t = 2.3 hours

r = ??

d = rt            Substitute

41 = r * 2.3   Divide by 2.3

41 / 2.3 = r   Switch sides

r = 41/2.3

r = 17.83 mph  Answer

The function below is written in vertex form or intercept form. Rewrite them in standard form and show your work.
lora16 [44]

Answer:

The standard form as y=5x^2+30x+41

Step-by-step explanation:

Given: A function which is written in vertex form or intercept form.

We have to re-write it  in standard form that in terms of

Given y = 5(x+3)^2-4

Squaring  using (a+b)^2=a^2+b^2+2ab , we get,  

y=5(x^2+9+6x)-4

Multiply 5 inside , we get,

y=5x^2+45+30x-4

Solving further , we get,

y=5x^2+30x+41

Thus , we have obtained the standard form as y=5x^2+30x+41
