Answer:
the answer is y= -1/2x+1/2
Step-by-step explanation:
Answer:
inches
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
= 2πr ×
= 2π × 10 ×
= 20π × = = inches
3. slope is 7 (slope = rise/run) count from the left most point to the other
up 7 right 1 both positive so slope = 7/1 reduced is 7
4. slope is 1/3 same process as above
up 1 right 3 both positive movement so slope is 1/3
5. y = 1/3x - 4 slope intercept form is y = (slope)x + (y-intercept)
y-intercept is where the graph touches the y-axis
6. y = 3x + 4
Answer:
Hence, the set that represent a negative linear association between x and y is:
Set A.
Step-by-step explanation:
We are given 4 sets of data as:
Set A
x 1 2 3 4 5 6 7 8 9
y 10 9 8 7 6 5 4 3 2
Set B
x 1 2 3 4 5 6 7 8 9
y 3 4 5 6 7 8 9 10 11
Set C
x 1 2 3 4 5 6 7 8 9
y 8 6 5 4 3.5 3 2.5 2 2
Set D
x 1 2 3 4 5 6 7 8 9
y 1 2.5 2.5 3 4 5 6 8 9
We are asked to determine the set which represent negative linear association between x and y?
Clearly in Set B and Set D the values of y keeps on increasing as the value of x increases; hence they both represent a positive linear association between x and y.
In set C the relationship is non-linear though it is negative.
Clearly in Set A we could see that the the y is related to x as:
y=11-x or y= -x+11.
Hence, clearly we could see that the relationship is linear and also negative as the value of y keeps on decreasing with increasing x.
