Answer:
The value of k is 11.
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
2=(k-3)/(5-1)
2=(k-3)/4
2*4=k-3
8=k-3
k=8+3
k=11
<em>If the rate is a constant, the relationship is proportional.</em> (The rate is the constant of porportionality.)
_____
For two or more points on the function curve, divide the dependent variable value by the independent one. If you get the same result in every case, the relationship is porportional.
___
<em>Note</em>
For some non-proportional relationships, it is possible to find points on the graph that will pass the above test. If you suspect the relationship is actually not one of proportionality, try more points. Check also to make sure that (0, 0) is on the curve.
Answer:
15 yds
Step-by-step explanation:
12 in = 1ft
3 ft = 1yd
to convert
540 in * 1ft/12 in * 1yd /3 ft = (540 * 1 * 1)/ (12*3) = 540/36 =15 yds
all the units canceled except for yds
Answer:
mean: 8.9, median: 9, mode: 3, range: 14, standard deviation: 5.1
Step-by-step explanation:
The mean is all the numbers added up, divided by how many numbers there are. To get the median you arrange the numbers biggest to smallest and find the middle number.
