Total online purchase is $26.473 .

Step-by-step explanation:

As given

Natasha places an online order for plate holders to display her antique plates.

Natasha orders 3 large holders for $4.95 each, 2 medium holders for $3.25 each and 2 small holders for $1.75 each.

Thus

Total purchase of Natasha = Number of large holders × Cost of each large holder + Number of medium holders × Cost of each medium holder +  Number of small holders × Cost of each small holder .

Put all the values in the above

Total purchase of Natasha = 3 × $4.95+ 2 × $3.25 + 2 × $1.75

                                            = $14.85 + $6.5 + $3.5

                                            = $ 24.85

As given

Site has a promotional offer of 15% off on all purchases.

15% is written in the decimal form

= 0.15

Discount amount = 0.15 × Total purchase of Natasha .

                             = 0.15 × $24.85

                             = $ 3.7275

Thus

Total purchase of Natasha after discount = Total purchase of Natasha - Discount amount .

                                                                     = $24.85 - $3.7275

                                                                     = $ 21.1225

As given

Natasha must pay a flat rate of $5.35 for shipping and handling.

Thus

Total online purchase of Natasha = Total purchase of Natasha after discount + Flat rate for shipping and handling .

Total online purchase of Natasha = $21.1225 + $5.35

                                                        = $ 26.4725

                                                        = $26.473 (Approx)

Therefore the total online purchase is $26.473 .

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
