Answer:

9 hrs

Step-by-step explanation:

Joshua has already saved $43.50 so you subtract $43.50 from 70 which leaves you with $26.50. Joshua still needs $26.50.

$26.50 divided by $3 per hr is 8.833 repeating. Obviously you can’t work 8.833 hrs so you round it up to 9. So, Joshua has to work for at least 9 hrs more.

Hope this helps :)

A box contains 35 gems, of which 10 are real diamonds and 25 are fake diamonds. Gems are randomly taken out of the box, one at a

Sonja [21]

Answer:

Step-by-step explanation:

The total number of ways of selecting 3 gems of any kind without replacement is 35 * 34 * 33 = 39270

Now selecting 2 gems from 25 is 25C2

25 C 2 = 25 * 24/2 = 300

Selecting one good gem is 10

Total selection = 300 * 10 = 3000

P(gems) = 3000 / 39270

P(gems) = 300/3927

P(gems) = 100/1309
