Answer:
Coordinate points are (0,0) and (1,1)
Step-by-step explanation:
Answer:
Part A: Yes, there should be a strong negative correlation between number of hours of internet browsing and score on math test. Justification: By calculating the correlation coefficient it is about -1. This means there is a strong negative correlation. Part B:y=-2x+95 Part C: The slope indicates that scores on a math test decrease by two for every hour internet browsing. The y-intercept indicates the score you have when browsing 0 hours on the internet.
Step-by-step explanation:
I hope this helps :D. I recommend getting a t-inspire calculator if you don't already have one. It can be so helpful when solving these types of problems.
Answer:
The revenue for 105 units will be <u>5985 thousand dollars.</u>
Step-by-step explanation:
Given:
The number of units is represented as 'u' and the revenue in thousands is represented as 'R'.
Let us find the ratio 'R' and 'u' and check the type of relationship.
Therefore, the ratio is a constant. Hence, the relationship is a proportional relationship.
A proportional relationship is given as:
Where, 'k' is the constant of proportionality and is equal to the ratio of any two values of 'R' and 'n'.
Therefore,
So, the relationship is
Now, we are asked to determine 'R' when . Plug in 105 for 'n' in the above relationship and find 'R'. This gives,
Therefore, the revenue for 105 units will be 5985 thousand dollars.
<span>slope of -1/2 and a y-intercept of 4, so m = -1/2 and b = 4
using y = mx + b
y = -1/2x + 4
answer is </span><span>B. y= -1/2x +4</span>
