What is the y-intercept of f(x)<br> -(1)?<br><br> A. (1,0)<br> B.(1 1/4)<br> C. (0,0)<br> D. (0,1)
Nataly [62]

Y intercept is where our x variable is equal to 0 and where the graph touches the y-axis.

Therefore, you can get the y intercept by just plugging in x = 0. For example, in the linear function: f(x) = 2x + 3, our y intercept would be (0,3) because we just set our x value equal to 0.

4.) A bag contains 10 red marbles and 5 blue marbles. You randomly select 3 marbles from the bag. What is
sesenic [268]

Answer:

a) 1/27

b) 2/91

Step-by-step explanation:

A bag contains 10 red marbles and 5 blue marbles (15 marbles in total). You randomly select 3 marbles from the bag.

a) You replace each marble before selecting the next one.

The probability of selecting one blue marble is

\dfrac{5}{15}=\dfrac{1}{3},

then the probability that all 3 marbles are blue is

\dfrac{1}{3}\times \dfrac{1}{3}\times \dfrac{1}{3}=\dfrac{1}{27}

b) You do not replace each marble before selecting the next one. Each time the number of blue marbles decreases by 1 and the total number of marbles decreases by 1 too. So the probability that all 3 marbles are blue is

\dfrac{5}{15}\times \dfrac{4}{14}\times \dfrac{3}{13}=\dfrac{2}{91}
