An outlier is a datapoint outside of the first or third quartile +/- 1.5 the inter quartile range
25 33 39 40 41 41 45 46 48 49 51 52 67 73 79
46 is at the center-> median
everything left of it:
25 33 39 40 41 41 45
40 at center=Q1
right of Q2:
48 49 51 52 67 73 79
52 at center=Q3
IQR=Q3-Q1=52-40=12
Q1-1.5*IQR=40-1.5*12=40-18=22
Q3+1.5*IQR=52+1.5*12=52+18=60
so everything <22 or >60 are outliers
so 67,73 and 79 are outliers
Answer:
equation: c = 4.80h + 18.30, cost for four hours: (4, 37.5)
Step-by-step explanation:
the equation is c = 4.80h + 18.30 because 18.30, the initial cost, is the y-intercept and because each hour costs $4.80. the cost for four hours would be (4, 37.5) because it costs $37.5 to skate for four hours.
Step-by-step explanation:
I don't understand, why there is this segment about the 0 degrees Kelvin.
any material, water or the glass the water is in, or the air, or the floor or the wall : the higher the temperature (the scale does not matter, as long both temperatures use the same), the more energy it contains (the faster the particles in that substance are moving/vibrating).
therefore a glass of water with 80 degrees will have much more energy than one with 20 degrees.
the same way an aluminum can (the actual name of that material is aluminium, but Americans seemingly cannot pronounce that) with 30 degrees has more energy than one with 20 degrees.
Answer:
The first one
Step-by-step explanation:
You can see the pattern
Answer:
-3/4 slope
Step-by-step explanation:
y = 3/4 x +2 has a slope of 3/4
Perpendicular lines intersect.
So the slope of the perpendicular line must be opposite.
