Slope is -2/3 and y-intercept is 10
If one basket is selected at random, the probability that both are mangoes is; 1/10
<h3>How to find probabilities?</h3>
Contents of first basket;
3 mangoes
4 oranges
3 apples
Contents of second basket;
5 mangoes.
5 oranges.
5 apples.
Probability of mango in first basket is = 3/10
Probability of mango in second basket is = 5/15
Thus;
Probability that both are mangoes = (3/10) * (5/15)
Probability that both are mangoes = 1/10

Answer:
2.45 seconds to the nearest hundredth.
Step-by-step explanation:
Acceleration a = -5, distance s = 15, time = ?.
Final velocity = v = 0.
We need to use the equations of motion under constant acceleration.
v^2 = u^2 + 2as where u is the initial velocity
0 = u^2 + 2*-5*15
u^2 = 150
so u = √150
Now we use v = u + at:
0 = √150 - 5t
t = √150/5
t = 2.45 seconds.
