You are working with a team of programmers to write a program for a Wheel of Fortune game. Your task is to write a method that will return how many times a letter is found in a String puzzle. For example, if the puzzle is "Last Minute Gift Shopping" and a player chose the letter "s", the value 2 would be returned.

In another class, you are given the statements

WheelOfFortune puzzle1 = new WheelOfFortunePuzzle("Last Minute Gift Shopping");
String letter = "s";
System. out. println("The letter " + letter + " is found: " + puzzle1.howMany(letter) + " times");

That outputs: The letter s is found 2 times

Fill in the missing code to complete the method howMany() for the WheelOfFortune class:

public class WheelOfFortune
{
private String puzzle;

public WheelOfFortune (String p)
{
puzzle = p;
}

public static howMany(String letter)
{
int count = 0;
for (int i = ; i puzzle. length(); i++)
{
if( .substring(i, i+1).equalsIgnoreCase( ))
{
;

}
}
return ;
}
}

You need to design a circuit that implements the functions in the following table: s0 s1 function0 0 a + 10 1 a – b1 0 a + b1 1 a – 1s0 and s1 are 1-bit control inputs to select the function of the circuit. inputs a and b are 4-bitnumbers in 2s complement form. the output is also a 4-bit number in 2s complement form.you are allowed to use only one ttl 7483 4-bit adder to implement all the functions. but anynumber of other components (except the adder) can be used.hint: design a combinational logic circuit to modify the input b and the “carry input” of theadder depending on the control inputs s0 and s1.important: lab grade will depend on the working of the circuit & will be checked of by your labinstructor.1. is the output valid for the following input combinations: a. s0 = 0, s1 = 0, a = 7, b = 3? b. s0 = 0, s1 = 1, a = 7, b = 3? c. s0 = 1, s1 = 0, a = -4, b = -5? d. s0 = 1, s1 = 1, a = -8, b = 6? 2. what is the range of inputs (for both a and b) that will produce the valid output for all the functions?

An environmental protection agency study of 12 automobiles revealed a correlation of 0.47 between engine size and emissions. at 0.01 significance level, can we conclude that there is a positive association between the variables? what is the p value? interpret.
