Answer:
Step-by-step explanation:
we have a circle inscribed in a square
Area of the square
Asquare=14*14=196
Acircle=3.14*r^2
r=14/2=7
Acircle=3.14*7^2=153.94
A shaded=196-153.94=42.06
The probabilty of picking a blue pen is one higher than picking a black pen
<span>The Range Rule of Thumb says that the range is about four times the standard deviation. (i.e. two standard deviations to the left and two standard deviations to the right of the mean).
Given that the mean is 500 and the standard deviation is 50, then
The minimum and the maximum "usual" values are given by

Therefore, the minimun "usual" value is 400 while the maximum "usual" value is 600.

Step-by-step explanation:
The geometric mean of 2 numbers a and b is 
The third term is the geometric mean of the first and fifth terms, that is
a₃ =
= 31.5
The second term is the geometric mean of the first and third terms, that is
a₂ =
= 10.5
The fourth term is the geometric mean of the third and fifth terms, that is
a₄ =
= 94.5
Thus the sequence is
3.5, 10.5, 31.5, 94.5, 283.5
