Hat is he probability of pick 1 green marble from a bag with 7 green and 8 blue marbles
disa [49]

Answer:

7/15

Step-by-step explanation:

<em>No. of green marbles in the bag= 7</em>

<em>No. of blue marbles in the bag= 8</em>

<em>Total no. of marbles in the bag= 7+8=15</em>

As we know that,

Probability( of a random event A)= \frac{Favourable\ no.\ of\ elementary\ events}{Total\ no.\ of\ elementary\ events}

Hence in this case,

Favourable np. of elementary events (green marbles)=7

Total no. of elementary events (Total no. of marbles in the bag)= 15

Hence, Probability of picking a green marble from the bag=\frac{7}{15}

Which of the following statements are true of the
Anuta_ua [19.1K]

Answer:

B, D, and E.

Step-by-step explanation:

A) The system has infinitely many solutions. This is wrong because according to the graph, there is only one solution- where the lines intersect. This would only be true if the lines never intersected.

B) A solution to the system is (-1, -2). This is true because this is the only point where the lines intersect.

C) A solution to the system is (0, -1). Since these aren't parabolas and the one above is true, we can say this is false. Also, the lines don't intersect at (0, -1).

D) One of the equations is y=x-1. This is true because the y-intercept for the red line is -1 and the slope of the equation is 1. You can also find this out by directly solving for the equation.

E) One of the equations is 3x+y=-5. If you put this into slope-intercept form, you will find out that the equation is y=-3x-5. This is true because the y-intercept of this is -5 and the slope of this is -3.
