What is the ratio of 8 to 8

Mathematics

Answer:

1:1

Step-by-step explanation:

A ratio says that "for every _ of this quantity, you have _ of another quantity". This is just saying for every 8 of one thing, you have 8 of another. And then you can simplify, just like a fraction.

Answer:

1 to 1

Step-by-step explanation:

8 to 8 = 8:8 = 8/8

You can treat a ratio as a fraction. Reduce the fraction 8/8 by dividing the numerator and denominator by 8.

8/8 = 1/1

8 to 8 = 1 to 1

Three bottles of different sizes contain different compositions of red and blue candy. The largest bottle contains eight red and
choli [55]

Answer:

0.3667

0.2727

Step-by-step explanation:

a)

P (Blue) = P (large and Blue) + P (mid and Blue) + P (small and Blue)

P (Blue) = (0.5 * 0.2) + (0.4*7 / 12) + (0.1* 1 / 3)

P (Blue) = 0.3667

b)

Conditional Probability:

P (Large / Blue ) = P (large and Blue) / P ( Blue)

P (Large / Blue ) = 0.5*0.2 / 0.36667

P (Large / Blue ) = 0.2727

A parabola can be drawn given a focus of (-11, -2) and a directrix of x= -3
fgiga [73]

Check the picture below, so the parabola looks more or less like that.

now, the vertex is half-way between the focus point and the directrix, so that puts it where you see it in the picture, and the horizontal parabola is opening to the left-hand-side, meaning that the distance "P" is negative.

\textit{horizontal parabola vertex form with focus point distance} \\\\ 4p(x- h)=(y- k)^2 \qquad \begin{cases} \stackrel{vertex}{(h,k)}\qquad \stackrel{focus~point}{(h+p,k)}\qquad \stackrel{directrix}{x=h-p}\\\\ p=\textit{distance from vertex to }\\ \qquad \textit{ focus or directrix}\\\\ \stackrel{"p"~is~negative}{op ens~\supset}\qquad \stackrel{"p"~is~positive}{op ens~\subset} \end{cases} \\\\[-0.35em] \rule{34em}{0.25pt}

\begin{cases} h=-7\\ k=-2\\ p=-4 \end{cases}\implies 4(-4)[x-(-7)]~~ = ~~[y-(-2)]^2 \\\\\\ -16(x+7)=(y+2)^2\implies x+7=-\cfrac{(y+2)^2}{16}\implies x=-\cfrac{1}{16}(y+2)^2-7

It’s a easy mathswatch questionnnnn helpppppp meeeeeeeee
pychu [463]

Answer:

15, 6 and - 3

Step-by-step explanation:

Given x - y = 3 , then

(a)

5(x - y) = 5(3) = 15

(b)

2x - 2y ← factor out 2 from each term

= 2(x - y) = 2(3) = 6

(c)

y - x ← factor out - 1 from each term

= - 1(x - y) = - 1(3) = - 3
