A security alarm requires a four-digit code. The code can use the digits 0–9 and the digits cannot be repeated.

Which expression can be used to determine the probability of the alarm code beginning with a number greater than 7?

StartFraction (2 P 1) (9 P 3) Over 10 P 4 EndFraction
StartFraction (2 C 1) (9 C 3) Over 10 C 4 EndFraction
StartFraction (10 P 1) (9 P 3) Over 10 P 4 EndFraction
StartFraction (10 C 1) (9 C 3) Over 10 C 4 EndFraction

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
