A bag contains 14 green, 12 orange and 19 purple tennis balls.
Nataliya [291]

Answer:

See explanation

Step-by-step explanation:

There are 14 green, 12 orange and 19 purple tennis balls in the bag,

14+12+19=45 balls in total.

A. The propbabilities that

a randomly chosen ball from the bag is green =\dfrac{14}{45};

a randomly chosen ball from the bag is orange =\dfrac{12}{45}=\dfrac{4}{15};

a randomly chosen ball from the bag is purple =\dfrac{19}{45}.

A probability model for choosing a tennis ball from the bag is

\begin{array}{lccc}\text{Ball}&\text{Green}&\text{Orange}&\text{Purple}\\ \\\text{Probability}&\dfrac{14}{45}&\dfrac{4}{15}&\dfrac{19}{45}\end{array}

B. Suppose a tennis ball is randomly selected and then replaced 75 times. You can expect that orange ball appear

\dfrac{4}{15}\times 75=4\times 5=20 times

((PLEASEEE HELPP MEE))
andrezito [222]

Answer:

D.

Step-by-step explanation:

In order to eliminate, the numbers must eliminate. If the second equation is multiplied by 3, then the 3 and the -3 can be eliminated. Since it is multiple choice, we can plug in x = 12 and y = 10 to see if they are correct. 12 + 30 = 42 and 24 - 10 = 14, so D is correct.

Solve system of equation using elimination by addition.<br><br> Will give brainliest!!
Rainbow [258]

Answer:

x = 6

Step-by-step explanation:

Add the system of equations together:
2x - 3y = 12

4x + 3y = 24

you get

6x = 36

divide by the coefficient

6x/6 = 1

36/6 = 6

x = 6

Not sure if you need the y, but if so, let me know!

Hope this helps!
