Answer:
The probability is ![\frac{3}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B20%7D)
Step-by-step explanation:
Consider a political discussion group consisting of 10 Democrats, 10 Republicans, and 5 Independents.
Total members of the group = ![10+10+5=25](https://tex.z-dn.net/?f=10%2B10%2B5%3D25)
Selecting 2 republicans in succession means selecting 1st republican out of 10 republicans and total 25 members and then selecting 2nd republican out of 9 left republicans and 24 members.
Hence, probability becomes:
![\frac{10}{25}\times \frac{9}{24}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B25%7D%5Ctimes%20%5Cfrac%7B9%7D%7B24%7D)
= ![\frac{90}{600} =\frac{3}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B90%7D%7B600%7D%20%3D%5Cfrac%7B3%7D%7B20%7D)
So, the probability is ![\frac{3}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B20%7D)
Decimal for 3/5= 6/10 = 0.6
Perimeter is 24.
Length is 4 greater than the width.
Let's use 'x' for width
we can write this as x+4 + x+4 + x + x
x+4 being the width+4 and x being the width
There are 4 sides to a rectangle so you are adding 4 values
Two length and two widths
so we can then combine the two lengths to make 2x+8
and then combine the two widths to make 2x
Then put it together. 2x+2x+8= 4x+8
4x+8=24
Subtract 8 from both sides
4x=16
divide both sides by 4
x=4
The width is 4.
8x - 13y = 16
At the x intercept y = 0 so we have:-
8x - 13(0) = 16
8x = 16
x = 16/8 = 2
so the x intercept is at (2,0)
