​The Westchester Chamber of Commerce periodically sponsors public service seminars and programs.

The Westchester Chamber of Commerce periodically sponsors public service seminars and programs. Currently, promotional plans are under way for this year's program. Advertising alternatives include television, radio, and online. Audience estimates, costs, and maximum media usage limitations are as shown: 

To ensure a balanced use of advertising media, radio advertisements must not exceed 45% of the total number of advertisements authorized. In addition, television should account for at least 10% of the Television Radio Online $1,500 $250 $500 18 total number of advertisements authorized 

(a) If the promotional budget is limited to $24,000, how many commercial messages should be run on each medium to maximize total audience contact? If your answer is zero enter "0" 

What is the allocation of the budget among the three media?

What is the total audience reached? 

(b) By how much would audience contact increase if an extra $100 were allocated to the promotional budget? Round your answer to the nearest whole number.

The Carbondale Hospital is considering the purchase of a new ambulance. The decision will rest partly on the anticipated mileage to be driven next year. The miles driven during the past 5 years are as follows:

a) Using a 2-year moving average, the forecast for year 6  = _______ miles (round your response to one decimal place).

b) If a 2-year moving average is used to make the forecast, the MAD based on this = _______  miles 

c) The forecast for year 6 using a weighted 2-year moving average with weights of 0.35 and 0.65 (the weight of 0.65 is for the most recent period) =_______  (round your response to the nearest whole number). 

The MAD for the forecast developed using a weighted 2-year moving average with weights of 0.35 and 0.65= _______ miles

d) Using exponential smoothing with α = 0.40 and the forecast for year 1 being 3.100, the forecast for year 6 = _______  miles

(a) Find the names of suppliers who supply some blue part. 

(b) Find the ids of suppliers who supply some blue or magenta part.

 (c) Find the ids of suppliers who supply every magenta part. 

(d) Find the ids of suppliers who supply every part. 

(e) Find the ids of parts supplied by at least two different suppliers 

(f) Find the ids of the most expensive parts supplied by company name named "Screw-2-You Limited". 

(g) Find the ids of parts supplied by every supplier at less than or equal to $50. (If any supplier either does not supply the part or charges more than $50 for it, then that part should not be in the final relation.)

Given an array of numbers, find the index of the smallest array element (the pivot), for which the sums of all elements to the left and to the right are equal. The array may not be reordered. 

Example arr=[1,2,3,4,6] 

• the sum of the first three elements, 1+2+3=6. The value of the last element is 6. 

• Using zero based indexing, arr[3]=4 is the pivot between the two subarrays. 

• The index of the pivot is 3. 

Function Description 

Complete the function balancedSum in the editor below. 

balanced Sum has the following 

parameter(s): 

       int arr(n): an array of integers 

Returns: 

       int: an integer representing the index of the pivot

Constraints 

•  3≤n≤10⁵ 

• 1≤ arr[i]≤ 2 * 10⁴, where 0≤i

• It is guaranteed that a solution always exists.

Even Subarray A subarray is a contiguous portion of an array. Given an array of integers, determine the number of distinct subarrays that can be formed having at most a given number of odd elements Two subarrays are distinct if they differ at even one position their contents. For example, if numbers [1, 2, 3, 4] and the maximum number of odd elements allowed, k 1, the following is a list of the 8 distinct valid subarrays: [[1], [21, [3], [4], [1,2], [2, 31, [3, 4], [2, :

This chapter is filled with examples of statutes that have been struck down by the courts. A Texas law banning flag burning was rejected by the Supreme Court, as was a Louisiana death penalty statute. The Affordable Healthcare Act has been voided by two lower court judges, and the Supreme Court may or may not agree with the action.

Do you like the fact that courts can void laws that they determine to be in violation of the Constitution? Or is it wrong for appointed judges to overrule “the will of the majority” as expressed by elected members of Congress and state legislatures?

Halmar the Great has boasted to his hordes of followers that many a notorious villain has fallen to his awesome sword: His total of 650 victims consists of evil sorcerers, trolls, and orcs. These he has slain with a total of 700 mighty thrusts of his sword; evil sorcerers and trolls each requiring two thrusts (to the chest) and orcs each requiring one thrust (to the neck). When asked about the number of trolls he has slain, he replies, "I, the mighty Halmar, despise trolls four times as much as I despise evil sorcerers. Accordingly, four times as many trolls as evil sorcerers have fallen to my sword!" How many of each type of villain has he slain?
