Answer:
$0.0646 is the expected value of the draw.
Step-by-step explanation:
1 nickel = 5 cents
1 dime = 10 cents
1 penny = 1 cent
Total number of coins = 
Probability that a nickel is selected is = 14/35
Probability that a dime is selected is = 15/35
Probability that a penny is selected is = 6/35
So, the expected value of the draw will be =
= 6.457 cents ≈6.46 cents
So, in dollars it is = 
= $0.0646
So, $0.0646 is the expected value of the draw.
Answer:
A = πr² ← r is the radius and r = \frac{1}{2} d ← d is the diameter
Hence
π (\frac{1}{2} d)² = A, that is
\frac{d^2\pi }{4} = A ( multiply both sides by 4 )
d²π = 4A ( divide both sides by π )
d² = \frac{4A}{\pi } ( take the square root of both sides )
d = \sqrt{\frac{4A}{\pi } }
Answer:

Step-by-step explanation:
Answer:
y=5-4x / 2
I cant do the fraction symbol
Simplify by combing like terms to get 2x+5
The answers would be:
the coefficient is 2
the constant is 5
There are two terms.
