4:7
4x:7x

4x + 7x = 11x

11x = 33
x =3

4 x 3 = 12
7 x 3 = 21

So 12 and 21 are in a ratio of 4:7 and add up to 33

The number of parts is:
4+7= 11

33 photos/ 11 parts= 3 photos/part

Group 1: 4 parts* (3 photos/ 1 part)= 12 photos
Group 2: 7 parts* (3 photos/ 1 part)= 21 photos

Hey can you please help me posted picture of question
MArishka [77]
It would be letter D - 3648.

The probability of winning is 0.76 and the probability of losing is 0.24.

In each simulation the probability of winning exactly one match is:   P(win one match) = 2C1 x 0.76 x 0.24 = 0.3648

Multiply the result by 10,000 simulations to get the expected number of times that exactly one match is won.
   10,000 x 0.3648 = 3648 times.

Answer:

  (x, y) = (34/5, -4/5) = (6.8, -0.8)

Step-by-step explanation:

Subtract the first equation from the second to eliminate x.

  \left(\dfrac{x}{3}-\dfrac{y}{2}\right)-\left(\dfrac{x-5}{3}+\dfrac{y+2}{3}\right)=\left(\dfrac{8}{3}\right)-(1)\\\\y\left(-\dfrac{1}{2}-\dfrac{1}{3}\right)+\left(\dfrac{5}{3}-\dfrac{2}{3}\right)=\dfrac{5}{3} \qquad\text{partially simplify}\\\\-\dfrac{5}{6}y=\dfrac{2}{3} \qquad\text{subtract 1}\\\\y=-\dfrac{4}{5} \qquad\text{multiply by $-\dfrac{6}{5}$}

Substituting for y in the second equation, we can find x.

  \dfrac{x}{3}-\dfrac{1}{2}\left(-\dfrac{4}{5}\right)=\dfrac{8}{3}\\\\5x +6=40 \qquad\text{multiply by 15}\\\\5x=34\qquad\text{subtract 6}\\\\x=\dfrac{34}{5}

The solution is (x, y) = (34/5, -4/5) = (6.8, -0.8).
