Answer:
Y = - 12.55X1 + 276.52
Step-by-step explanation:
Given the data:
Age of child :(X) : 4, 6, 10, 13, 14, 17
Time (seconds) (Y) : 230, 205, 132, 119, 108, 62
Using technology, the linear regression equation obtained using the data Given is :
Y = - 12.55X1 + 276.52
Where :
Slope = - 12.55
Intercept = 276.52
This also indicates that a negative slope is present and hence a negative relationship between age of Child and time in seconds.
Answer:
Growth
Step-by-step explanation:
The number that is multiplying (1.01) is more than 0 so growth
The list of scores from the given box-and-whisker plot are:
Lowest score: 20
Lower quartile (Q1): 30
Median: 60
Upper quartile (Q3): 80
Highest score: 100
The range = 80
<h3>How to Determine the Scores or Data Point from a Box-and-whisker Plot?</h3>
There are specifically 5 values that are referred to as the five-number summary which are displayed by a typical box-and-whisker plot. As shown in the image attached below, these values include the following:
- The minimum value which is the least value
- The lower quartile value (Q1)
- The median value
- The upper quartile value (Q3),
- The maximum value which is the largest data score.
Thus, from the box-and-whisker plot that is given in this question, the five-number summary are:
Minimum value (lowest score): 20
Lower quartile value (Q1): 30
Median: 60
Upper quartile value (Q3): 80
Maximum value (highest score): 100
The range = max - min = 100 - 20
The range = 80

Answer:
x=14
Step-by-step explanation:
If the y=8 then plug it in the equation:
3x-5(8)=2
It will be:
3x-40=2
3x=42
x=14
