Answer:
Step-by-step explanation:
<u>Use of formula:</u>
- P(A and B) = P(A)*P(B|A) and
- P(A and B) = P(B)*P(A|B)
<u>According to above and based on given:</u>
- P(A)P(B|A) = P(B)P(A|B)
- P(B|A) = P(A|B)*P(B)/P(A)
- P(B|A) = 0.20*0.40/0.25 = 0.32

I've never had to deal with this before but I would say C
Answer:
19.6 cm²
Step-by-step explanation:
If a circle fits perfectly inside of a square, then its diameter is equal to the length of sides of the square.
The area of a circle is given by:

In this problem, d = 5 cm, the area of the circle is:

The approximate area of the circle is 19.6 cm².
4v
You would subtract 10-6
Then you would add the v
When you are doing distributive property, it can only happen if a number or exponent is before the bracket. From this equation, you can solve for x like so:
7(x+5)-x=42
7x+35-x=42 -Using distributive property (Multiplication)
6x=7 -Collecting like terms.
x= 7/6 -The answer.
Therefore x would equate to 7/6.
