Answer: -1.5
because one of the numbers is - 10 => the other is 15/-10 = -1.5
Step-by-step explanation:
The current it conduct when it is plugged into a wall outlet that provides 120 V is 10.4A
<h3>Ohms law</h3>
The current passing through a conductor is proportional to the potential difference. Mathematically;
V = IR
where
V is the voltage = 120V
R is the resistance = 11.5 ohms
Required
Current I
Substitute
I = V/R
I = 120/11.5
I = 10.4A
Hence the current it conduct when it is plugged into a wall outlet that provides 120 V is 10.4A

Answer:
Probability that a student who passed the test did not complete the homework = 0.07
Step-by-step explanation:
Given:
Total number of students = 28
Number of students who passed the test = 18
Number of students who completed the assignment = 23
Number of students who passed the test and also completed the assignment = 16
To find: probability that a student who passed the test did not complete the homework
Solution:
Probability refers to chances of occurrence of some event.
Probability = number of favorable outcomes/total number of outcomes
Let A denotes the event that students passed the test and B denotes the event that students completed the assignment
P(A only) = ![P(A)-P(A\cap B)](https://tex.z-dn.net/?f=P%28A%29-P%28A%5Ccap%20B%29)
Here,
![P(A)=\frac{18}{28}\,,\,P(A\cap B)=\frac{16}{28}](https://tex.z-dn.net/?f=P%28A%29%3D%5Cfrac%7B18%7D%7B28%7D%5C%2C%2C%5C%2CP%28A%5Ccap%20B%29%3D%5Cfrac%7B16%7D%7B28%7D)
So,
![P(A\,\,only)=\frac{18}{28}-\frac{16}{28}=\frac{2}{28}=\frac{1}{14}=0.07](https://tex.z-dn.net/?f=P%28A%5C%2C%5C%2Conly%29%3D%5Cfrac%7B18%7D%7B28%7D-%5Cfrac%7B16%7D%7B28%7D%3D%5Cfrac%7B2%7D%7B28%7D%3D%5Cfrac%7B1%7D%7B14%7D%3D0.07)
Therefore,
probability that a student who passed the test did not complete the homework = 0.07
