Answer:

42 + 2n  ≥ 80

Step-by-step explanation:

Given,

Naomi's earnings for one day = $ 42,

Also, she earns extra $2 for each CD she sells,

Thus, the extra earning for n CDs = 2n dollars,

So, her total earning for a day if she sells n CDs = ( 42 + 2n ) dollars,

If Naomi wants to earn at least $80 per day,

Her total earning ≥ 80 dollars,

⇒ 42 + 2n  ≥ 80

Which is the required inequality.

If you roll six sided dice what are the odds of rolling doubles
Ludmilka [50]

Answer: 16.7%

There are 6 ways we can roll doubles out of a possible 36 rolls (6 x 6), for a probability of 6/36, or 1/6, on any roll of two fair dice. So you have a 16.7% probability of rolling doubles with 2 fair six-sided dice.

Second Answer : 6/36

Out of the 6^2 = 36 outcomes, there is only 6 that are doubles (double 1,double 2,… double 6). Therefore the probability is 6/36 i 1/6.
