The decrease count () function in the previous exercise currently returns 0 if sufficient resources are available and −1 otherwise. This leads to awkward programming for a process that wishes to obtain a number of resources: while (decease_count(count) == -1) ; Rewrite the resource-manager code segment using a monitor and condition variables so that the decrease count() function suspends the process until sufficient resources are available. This will allow a process to invoke decrease_count () by simply calling decrease_count (count) ; The process will return from this function call only when sufficient resources are available.

Write a method isEven that uses the remainder operator (%) to determine whether an integer is even. The method should take an integer argument and return true if the integer is even and false otherwise. Incorporate this method into an application that inputs a sequence of integers (one at a time) and determines whether each is even or odd.

For how many years has San Juan been the capital of Puerto Rico?

The mean height of American men between 20 and 29 years old is 69 inches, and the standard deviation is 3 inches. A 20- to 29-year-old man is chosen at random from the population. The probability that he is 6 feet tall or taller is

$$P(72 \leq x<\infty)=\int_{72}^{\infty} \frac{1}{3 \sqrt{2 \pi}} e^{-(x-69)^2 / 18} d x$$

(a) Use a graphing utility to graph the integrand and estimate that the area between the $x$-axis and the integrand is approximately 1.

Solve. -5(2x-9)=2(x-8)-11

In your own words, explain why the volume = (height) - (area of the base) formula is valid for right prisms using the example of a prism that is $5 \mathrm{~cm}$ high and that has a base of area $8 \mathrm{~cm}^2$.

Consider this word problem about baking brownies:

You are baking brownies for your class. You put white frosting on $\frac{1}{3}$ of the brownies and you put small red hearts on $\frac{1}{4}$ of the brownies. How many brownies have both white frosting and small red hearts on them?

(a). Can the brownie problem be solved? If so, solve the problem; if not, explain why not.

(b). Is the brownie problem a problem for $\frac{1}{4}+\frac{1}{3}$ ? If so, explain briefly why it is; if not, modify the problem so that it is a problem for $\frac{1}{4} \cdot \frac{1}{3}$.

($c$). Is the brownie problem a problem for $\frac{1}{3}+\frac{1}{4}$ ? If so, explain briefly why it is; if not, modify the problem so that it is a problem for $\frac{1}{3}+\frac{1}{4}$.

Use the Chain Rule combined with other differentiation rules to find the derivative of the following functions.

$$y = ( z + 4 ) ^ { 3 } \tan z$$

The process of iron being oxidized to make iron(III) oxide (rust) is spontaneous. Which of these statements about this process is/are true? (a) The reduction of iron(III) oxide to iron is also spontaneous. (b) Because the process is spontaneous, the oxidation of iron must be fast. (c) The oxidation of iron is endothermic. (d) Equilibrium is achieved in a closed system when the rate of iron oxidation is equal to the rate of iron(III) oxide reduction. (e) The energy of the universe is decreased when iron is oxidized to rust.
