IgorC [24]

Answer:

Because e is used so commonly in math and economics, and people in these fields often need to take the logarithm with a base of e of a number to solve an equation or find a value, the natural log was created as a shortcut way to write and calculate log base e. ...

A bag contains 5 red marbles, 7 blue marbles and 2 green marbles. If two marbles are drawn out of the bag, what is the probabili
user100 [1]
Answer:
0.218

Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome of event/ Total outcome
If a bag contains 3 red marbles, 7 blue marbles and 5 green marbles, the total number of marbles in the bag will be the total outcome i.e 3+7+5 = 15
If two blue marbles are drawn, the expected outcome in both cases is 7 since there are 7 blue marbles in the bag.
Probability of drawing the first blue marble = 7/15
Probability of drawing the second blue marble = 7/15
Probability that both marbles drawn will be blue = 7/15*7/15
= 49/225
= 0.218 (to nearest 1000th)

m_a_m_a [10]

Explanation:

Steve correctly computed the change in x to be 2, and the change in y to be 6. However he put 2 in the slope formula for Δy (the change in y), and 6 for Δx. That is, Steve reversed the values of Δx and Δy.

The actual slope is ...

  slope = Δy/Δx = 6/2 = 3
