In both instances, there is a 20% chance that he gets a striped sweater. 2 x 2/10 is not the same as 2/10 x 2/10. You have to do 2/10 x 2/10, because there's a 20% chance he gets it first, and then 20% he gets it again. The chance he gets it twice in a row should be 4 out of 100 or 1 out of 25. A very slim chance

The probability to select a stripped shirt is 2/10
He replaced it, then the number of shirts is the same & the probability is the same.
But here there is a conditional probability
1st selection P(2/10)
AND
2nd selection P(2/10) so P( stripped shirt AND another stripped shirt)
=2/10 x2/10= 4/100 =1/25

How do I get the answer 1/2•-3 4/7
earnstyle [38]
First off, we need to convert the mixed fraction to "improper", and then just multiply linearly, let's do so,

\bf \stackrel{mixed}{3\frac{4}{7}}\implies \cfrac{3\cdot 7+4}{7}\implies \stackrel{improper}{\cfrac{25}{7}}
\\\\\\
\cfrac{1}{2}\cdot \cfrac{25}{7}\implies \cfrac{1\cdot 25}{2\cdot 7}\implies \cfrac{25}{14}\implies 1\frac{11}{14}

If 8q + 2r = 2q + 4, what is r in terms of q ?
Ilia_Sergeevich [38]
8q+2r=2q+4
Move 8q to the other side
2r= 2q+4+(-8q)
2r= 2q-8q+4
2r= -6q+4
(2r= -6q+4)/2
r=-3q+2
This is the most you can simplify this equation.

Hope this helps!

The radius of the semicircle in the following composite figure is 8.5 millimeters. What is the area of the semicircle rounded to
padilas [110]
You will find the area of the semicircle by finding the area of the circle with a radius of 8.5 mm and the dividing it by 2.

A = pi x r^2
3.14 x 8.5^2
A = 226.865 square mm
226.865/2
113.43

The approximate area of the semi circle is 113.43 mm².
