Mrs. Anderson surveyed her class and asked each student, "How many hours do you spend
playing sports per week?" The results are below.
0.0.0.0.2.2.3.3.33.44 1,5,5,5,5,5,5,5,5,5,6,6.6.6.6,6,6,6,6,7.7.8.12
Port A: Construct a dot plot of the data and choose the best graph from the choices below.
Part B: What observations can you make about the shape of the distribution
Part C: Are there any values that don't seem to fit? Justify your answer.
Answer:
The simple pendulum should be 15.9 m long.
Step-by-step explanation:
Approximately (for small amplitudes), the period of a simple pendulum is
T = 2*pi * sqrt (L/g), L=length
using pi = 22/7, and g=9.8 m/s^2
8 = 2* 22/7 * sqrt(L/9.8)
solve for L
L = (8*7/(2*22))^2 * 9.8
= 15.874 m
That's quite a long pendulum!

When u plug in what the x variable is in each equation, you figure out what y equals to.
1.y=(2)^3 +1 so y=8+1 so y=9
2.y=(-2)^3 +1 so y=-8+1 so y=-7
Answer:
You did it correctly that's the right answer
Great Job!
