Roughly 1.7 percent of the bands are shorter than 3cm. We calculate the z score of the data point in standard distribution. By definition of z score, we use score minus mean divided by standard deviation. z=(3-6)/1.5=-2. A z score of -2 corresponds to approximately 1.7%, in other words, roughly 1.7 percent of data is less than 3cm.
3/4 * h = 2 1/4
3/4* h * 4/3 = 9/4 * 4/3
h = 3
I think the answer would 28
Answer:
(-5,-28)

Look at graph.
Hope this helps!
Answer:
No they don't show direct variation because if you get y alone, the equation you get is in slope intercept form instead of direct variation.
Step-by-step explanation
direct variation: y=kx
y-x=4
+x +x
y= 4+x
Not Direct Variation
