Define
P(S) = probability that the student takes Spanish.
P(T) = probability that the student takes Technology
          (= 0.68).
P(T and S) = probability that the student takes Technology and Spanish
                     (= 0.087).
P(S|T) = probability that the student takes Spanish, given that the student takes Technology.

The Law of Conditional Probability is
P(T and S) = P(S|T)*P(T)

Therefore
0.087 = P(S|T)*0.68
P(S|T) = 0.087/0.68 = 0.128

Answer: P(S|T) = 0.128

Linear equation: -1
Anika [276]

Answer:

The right answer is:

the addition property of equality and then the division property of equality

Step-by-step explanation:

Given equation and steps to solve it are:

Step 1: –3x – 5 = 13

Step 2: –3x = 18

Step 3: x = –6

In step two, -5 has to be removed from left hand side of the equation so additional property of equality will be used i.e. adding 5 on both sides

Similarly in the third step, to remove -3 with x , division property of equality will be used i.e. dividing both sides by -3

Hence,

The right answer is:

the addition property of equality and then the division property of equality

A small cargo plane currently has 140 pounds of cargo aboard. In addition, n boxes weighing 45 pounds each will be brought aboar
Vika [28.1K]

Answer:

The inequality that represents this situation is: 140 + 45*n < p

Step-by-step explanation:

Since the plane already had 140 pounds on board and "n" boxes will be loaded on it, then the weigh of each box multiplied by the number of box should be the extra cargo on the plane. This extra cargo added to the previous load must be less than the limit of cargo the plane can take as shown below:

140 + 45*n < p
