Given:
A box-and-whisker plot of data set.
To find:
The percentage of the data values that are greater than 80.
Solution:
From the given box-and-whisker plot, it is clear that:
Minimum value = 8
First quartile = 60
Median = 68
Third quartile = 80
Maximum value = 92
We know that the 25% the data value are greater than or equal to third quartile because the third quartile divides the data in 75% to 25% and 80 is the third quartile.
Therefore, about 25% of the data values that are greater than 80.
Answer:
20
Step-by-step explanation:
trust me.
Answer:
12
Step-by-step explanation:
a2 +b2 = c2
a2 + 9 2 = 15 2
a2 + 81 = 225
- 81 - 81
a2 = 144
a = 12
R = 230 m
v = 17 m/s
Formula: |Ac| = v^2 / r
Point A
|Ac| = v^2 / r = (17m/s)^2 / (230m) = 1.257 m/s^2
Components:
cos(25) = - [ x-component / |Ac| ] => x-component = -|Ac|*cos(25)
sin(25) = - [y-component / |Ac| ] => y-component = - |Ac|*sin(25)
x-component = - 1.256 * cos(25) m/s^2 = - 1.139 m/s^2
y-component = -1.256 * sin (25) m/s^2 = - 0.531 m/s^2
Point B
|Ac| = 1.256
x-component = - 1.256 cos(58) = - 0.666 m/s^2
y-component = + 1.256 sin(58) = + 1.065 m/s^2
