1. Here are the four steps of the statistical process in correct order:
1) Plan - <span>Form a question that can be answered by data.
2) Collect data - D</span><span>esign and implement a plan that collects data.
3) Process - </span><span>Analyze the data using graphical and numerical methods.
4) Present and discuss - </span><span>Interpret and compare the data.
So your answer is the last option.
2. I am definitely sure that </span><span>Edgar wrote a statistical, because every neighbor can give a different answer. A statistical question is the question which you don't expect to get only one answer. Instead of that you will get a variety of different answers.
3. According to what I've mentioned before, the only statement which shows a characteristic of a statistical question is: </span><span>There can be variability in the answers to the question.
4. I am completely sure that this one is statistical question: </span>How many hours do you spend each week training for a sports league? Because it could be answered with variability.
5. The only statistical question in his survey is: <span>How many hours do you spend at the food court each month?. Because it gives him more different answers for his survey.</span>
Answer:
7
Step-by-step explanation:
Let 'x' represent the number of tickets that Teresa sold, and x is integer and x>=0 (you can not sell negative number of tickets)
6 + 2x < 22
x < 8
The range of possible number of tickets that Teresa sold is {0, 1, 2, 3, 4, 5, 6, 7}.
Answer:
x=45
Step-by-step explanation:
2x+45+x=180
Combine 2x and x to get 3x.
3x+45=180
Subtract 45 from both sides.
3x=180−45
Subtract 45 from 180 to get 135.
3x=135
Divide both sides by 3.
x=135/3
Divide 135 by 3
x=45
Using relations in a right triangle, it is found that:
- Since x and y are complementary angles, we have that sin(xº) = cos(yº).
<h3>What are the relations in a right triangle?</h3>
The relations in a right triangle are given as follows:
- The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
- The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
- The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.
The hypotenuse in this problem is given as follows:
h = 10.
The sine of x is:
The cosine of y is:
Since x and y are complementary angles, we have that sin(xº) = cos(yº).
