Rachel received $650 for her birthday. she purchased a surfboard for $477 and some additional accessories without spending more than the money she received. she wrote the inequality 477 + x < 650. is the inequality correct? yes, because 477 and an unknown amount is less than 650. no, because 477 and an unknown amount is greater than 650. no, because the inequality symbol should be less than or equal to 650. no, because x should be subtracted from 477.

Amount received by Rachel on her birthday = $650

Amount spent on surfboard = $477

Let amount spent on some additional accessories be x

Total money spent = 477 + x

Without spending more than the money she received so the inequality sign between money spent and total money received will be less than or equal to

So the inequation will be 477 + x ≤650

So Rachel inequality is incorrect

Option C is the answer : No, because the inequality symbol should be less than or equal to 650.

it’s supposed to be -4+45=41

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
