Answer:
Dependent.
Quantitative.
Step-by-step explanation:
<u>Determine whether the sampling is dependent or independent.</u>
This is a matched-pair data test, as the same students are measured two times in order to compare the results.
This type of samples are dependent, as they are correlated between them.
<u>Indicate whether the response variable is qualitative or quantitative.</u>
The response variable is the test score. This is a quantitative variable, as this can be defined by a number. Both sample scores are averaged and compared.
Answer:13/24
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
Given the following :
Score when there were 4 innings left = 17 to 6
Kim's team = 6 ; opposition team = 17
Opposition didn't score any point in the last 4 innings
Kim's team scored same number of points per inning and also won with the most points
Minimum Number of points Kim's team could have scored per inning :
Let number of points scored in each of the last 4 innings = p
Since they also won eventually:
Then
4p + initial points > opposition point
4p + 6 > 17
4p > 17 - 6
4p > 11
p > 11/4
p > 2.75
Hence, the minimum number of points Kim's team could have scored per inning in the last 4 would be 3( nearest whole number)
Answer:
cost of each video game = $5.50
cost of each movie = $4.25.
Step-by-step explanation:
Let m represent cost per movie
g represents cost per video game.
Create two equations to represent the total cost Tammy rented movie and video games in each month, and solve simultaneously for each variable:
First month:
=> equation 1
Second month:
=> equation 2
Multiply equation 1 by 4, and multiply equation 2 by 2 to derive:
4 ×
2 ×
=> equation 3
=> equation 4
Subtract equation 4 from equation 3
You'd have:
- 4g = - 22
Divide both sides by -4
g = 5.5
Thus, the cost of each video game = $5.50.
Substitute g = 5.5 in equation 1 and solve for m.
Subtract 16.5 from each side
Divide both sides by 2
Thus, cost of each movie = $4.25.
