The third tree diagram is correct.

The probabilities for the first draw are 3/7 for green and 4/7 for red.

If you draw a green pear first, then your probabilities for the second pear would be 2/6 for green and 4/6 for red (since it is done without replacement, the number of pears to choose from changes).

If you draw a red pear first, then your probabilities for the second pear would be 3/6 for green and 3/6 for red.

Help me answer this question
Roman55 [17]

Answer:

  5 seconds

Step-by-step explanation:

When the ball returns to its original height, it will be 96 ft from the ground. That means we want to solve for t ...

  h(t) = 96

  96 +80t -16t^2 = 96

  16t(5 -t) = 0 . . . . subtract 96 and factor

This equation is true for t=0 and for t=5.

After 5 seconds, the ball will pass the top of the building on the way down.

Write an exponential equation in the form y = abx whose graph passes through points (2, 18) and (5, 60.75).
Nataliya [291]
Y = a * b^x
18 = a * b²
60.75 = a * b^5
60.75 = a * b² * b³
60.75 = 18 b³
b³ = 60.75 : 18
b³ = 3.375
b = ∛ 3.375
b = 1.5
18 = a * 1.5²
18 = a * 2.25
a = 18 : 2.25
a = 8
Answer:
y = 8 * 1.5^x
