Answer:
7/34
Step-by-step explanation:
Total number of chips in the bag = 8 + 7 + 2 = 17
⇒ P(blue) = 8/17
⇒ P(green) = 7/16 (since the first chip has not been replaced)
⇒ P(blue and green) = 8/17 x 7/16 = 7/34

Step-by-step explanation:
What is true of an equilateral triangle? Two of its side lengths are equal. <u><em>All its side lengths are equal</em></u>. None of its side lengths are equal. None of its interior angles are equal. What is true of an equilateral triangle ? Two of its side lengths are equal . All its side lengths are equal . None of its side lengths are equal . None of its interior angles are equal .
Here is the solution...
Compensation
The compensation is nothing but the process of reforming the given expression to find the answer mentally.
Here we need to rewrite the given expression in order find the answer mentally.
<u>Step 1:</u>
Here we can add 8 with 6572, so we get 6580.
<u>Step 2: </u>
Add 8 from 239, so we get 247.
<u>Step 3:</u>
We can rewrite 247 as 240 + 7
<u>Step 4:</u>
Now we can subtract 240 from 6580, so we get 6340.
We can calculate this mentally.
<u>Step 5:</u>
Finally, we can subtract 7 from 6340 mentally, So we get
6333.
Mathematically, the above expression written as
6572- 239
= 6572 + 8 - (239 + 8)
= 6580 - 247
= 6580 - (240 + 7)
= 6580 -240 - 7
= 6340 - 7
= 6333

Answer:
y=-3/7x+3
Step-by-step explanation:
A(0;3) B(7;0)
(y-yA)/(yB-yA)= (x-xA)/(xB-xA)
y-3/-3= x/7
7y-21=-3x
