A briefcase has a three- digit lock code that doesn't include zero as a digit. What is the probability that the lock code consis

storchak [24]

Answer:

1/21.

Step-by-step explanation:

There are 9 digits and the total number of permutations of 3 from 9 is 9P3

= 9!/6! = 504.

There are 4 even digits so the number of permutations of 3 from these 4 is 4! (4-3)! = 4*3*2 = 24.

So the required probability = 24/504

= 1/21.

SSSSS [86.1K]

Answer:

The answer is B. He spent 3 minutes eating lunch for every 10 minutes.

Step-by-step explanation:

He spent stuck inside during the brainstorm for:

20+18+12+10= 60 minutes in total.

And now we want to know what he did for every 10 minutes he spent in the rainstorm. To do that we need to divide what he did for every 10 minutes by the total of minutes that he was stuck:

$\frac{10}{60} =\frac{1}{6}$

And now we can multiply the time of the activities by 1/6 to get the time he did each activity every 10 minutes.

Reading:

$20*\frac{1}{6} = 3.33$ minutes reading for every 10 minutes.

Eating:

$18*\frac{1}{6} = 3$ minutes eating for every 10 minutes.

Watching TV:

$12*\frac{1}{6} = 2$ minutes watching TV for every 10 minutes.

Drawing:

$10*\frac{1}{6} = 1.67$ minutes drawing for every 10 minutes.

Therefore he spent 3 minutes eating lunch for every 10 minutes.

What percentage of 128 is 96?

katrin [286]

So, since 100% = 128, x should equal 96, and we are trying to find x.
Multiply both sides of the equation by x.
(100/x) * x = (128/96) * x
Cancel out the x's on the left side so
100 = 1.333(x)
75 = x
96 is 75% of 128
