Pam and Rachel buy books at the bookstore where Rachel works. Each uses a coupon. As an employee Rachel pays only 75% of the advertised price after her coupon is applied. Pam bought books for $4.00 each and used a $5.00 off coupon. Rachel bought books for $8.00 each and used a $4.00 off coupon. Is it possible for Pam and Rachel to purchase x books and pay the same amount? Use the equation 4x - 5 to represent Pams purchase and 0.75(8x - 4) to represent Rachel's purchase.

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

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹( $\frac{smaller force}{resultant}$

=tan⁻¹( $\frac{8}{10}$

=tan⁻¹(0.8)

=38.6°
