Answer: 84.9
Step-by-step explanation:
Model's equation: y=1.11x^2
Since y = 2000
y = 1.11x^2
2000 = 1.11x^2
x^2 = 2000/1.11
x^2 = 1801.8
x = 42.45
Diameter of the smallest circle will be:
= 2x
= 2 × 42.45
= 84.9
Answer:
Step-by-step explanation:
For n=129 and with leaf unit = 0.1, the stem and leaf chart of the given data on Shower-flow rate (L/min) is as follows:
2 28

4----------01356889
5----------00001114455666789

18 ----------3
* From steam and leaf chart we note that minimum Shower flow rate is 2.2 whereas maximum is 18.3 L/mim. Further typical or representative rate is 7.0 L/min.
* The display of data on steam and leaf chart shows that data is positively skewed means concentration of data on left side or lower value side is high as compared to other side.
* Distribution is not symmetric rather very clear positive skew ness is observed through steam and leaf chart. Even distribution is Unimodal.
* From steam and leaf chart is indicative to conclude that the highest observation 18.3 is outlier.
Acceleration is the rate at which velocity (speed) is changing. If an object is moving with a constant velocity, then its acceleration is zero, since the velocity never changes. ... So in that one second, the speed increased by 2 mph.
Answer:
n=7/3
Step-by-step explanation:
1 (n – 4) – 3 = 3 - (2n+3)
1. distribute the 1 on the left side and distribute the -1 on the right side
1n-4-3=3-2n-3
2. add like terms
1n-7=-2n
3. move n to one side and by itself
-7=-3n
4. divide -3 to get n alone. Both negatives cancel out each other
7/3=n
