Answer:
The correct option is - content analysis
Step-by-step explanation:
Dr. Jones is having his students use: content analysis.
Content analysis is a type of research technique, where we make similar and valid inferences by coding and interpreting information in text forms.
Here Dr. Jones is asking his students to gather information to identify the violent acts in each cartoon show. So, the students will be gathering content or information and then they will come to some inference.
I’m pretty sure it is the first one
Number of weekend minutes used: x
Number of weekday minutes used: y
This month Nick was billed for 643 minutes:
(1) x+y=643
The charge for these minutes was $35.44
Telephone company charges $0.04 per minute for weekend calls (x)
and $0.08 per minute for calls made on weekdays (y)
(2) 0.04x+0.08y=35.44
We have a system of 2 equations and 2 unkowns:
(1) x+y=643
(2) 0.04x+0.08y=35.44
Using the method of substitution
Isolating x from the first equation:
(1) x+y-y=643-y
(3) x=643-y
Replacing x by 643-y in the second equation
(2) 0.04x+0.08y=35.44
0.04(643-y)+0.08y=35.44
25.72-0.04y+0.08y=35.44
0.04y+25.72=35.44
Solving for y:
0.04y+25.72-25.72=35.44-25.72
0.04y=9.72
Dividing both sides of the equation by 0.04:
0.04y/0.04=9.72/0.04
y=243
Replacing y by 243 in the equation (3)
(3) x=643-y
x=643-243
x=400
Answers:
The number of weekends minutes used was 400
The number of weekdays minutes used was 243
To solve this problem you must apply the proccedure shown below:
1. You have that the ratio of the tangent function is:
tan(angle)=opposite/adjacent
2. Keeping this on mind, you have:
tan(A)=12/5
Therefore, the answer is:
tan(A)=12/5
