A box contains 16 large marbles and 18 small marbles. Each marble is either green or white. 9 of the large marbles are green, an

vfiekz [6]

Answer:

$P(S&G) =0.7941$

Step-by-step explanation:

From the question we are told that:

Sample size $n=16+18=>34$

N0 of Large $L=16$

N0 of Small $S=18$

N0 large Green $L_g=9$

N0 of small White $S_w=3$

Therefore

Number of green marbles $N0(G)=9+(18-3)$

Number of green marbles $N0(G)=24$

Generally the Number of both small and green Marble is

$N0 of (S&G)= 18 - 3 = 15$

Generally the probability that it is small or green P(S&G) is mathematically given by

$P(S&G) = \frac{(18 + 24 - 15)}{(18 + 16)}$

$P(S&G) =0.7941$

Find the equation, (f(x) = a(x-h)2+ k), for a parabola containing point (-1,0) and having (-3, 4) as a vertex. What is the stand

kirill115 [55]

$(h;\ k)\ -\ \text{the coordinates of the vertex}$

$\text{therefore we have:}\ f(x)=a(x+3)^2+4$

$\text{a parabola that passes through the point (-1; 0)}$

$\text{substitute the coordinates of the poin (-1; 0) to the equation}$

$(-1;\ 0)\to x=-1;\ y=0\\\\0=a(-1+3)^2+4\\\\0=a(2)^2+4\\\\0=4a+4\ \ \ |-4\\\\4a=-4\ \ \ |:4\\\\a=-1$

$f(x)=-(x+3)^2+4=-(x^2+2\cdot x\cdot3+3^2)+4=-(x^2+6x+9)+4\\\\=-x^2-6x-9+4=-x^2-6x-5$
