Answer:
0.339
Step-by-step explanation:
9 spot is the thousands place!
The value of W when V = 9 is 405
<h3>How to solve for W?</h3>
The variation is a direct variation from W to V^2.
This means that:
W = kV^2
Where k is the constant of variation.
W = 320 when V = 8 means that:
320 = k * 8^2
Evaluate
320 = 64k
Divide both sides by 64
k = 5
Substitute k = 5 in W = kV^2
W = 5V^2
When V = 9, we have:
W = 5 * 9^2
Evaluate
W = 405
Hence, the value of W when V = 9 is 405

Answer:
7/15
Step-by-step explanation:
7 boxes out of 10 contain $20. Therefore 3 boxes do not have $20 bills.
The probability of picking a bag with a $20 bill
= 7/10
The probability of picking another bag with $20 bill
= (7-1)/(10-1)
= 6/9
The probability of getting two $20 bills.
= 7/10 × 6/9
= 42/90
= 7/15
