Your worksheet contains a price in cell A5 and many formulas refer to that price how would you refer to that price in the formula

9. In a program with 25% loads, 10% stores, 11% branches, 2% jumps, 52% R-type. The standard CPI for each instruction type is 2 cycles loads, 2 cycles stores, 1 cycle branches, 2 cycles jumps, 1 cycle R-type. The branches have a misprediction penalty of an additional 2 cycles when it misses, which happens 30% of the time. Loads create a RAW hazard 20% of the time adding in an extra cycle to the execution time. What is the average CPI for this program on this processor

Given the following code, what logic would you need to include to print all even values stored within the array:

int[] myArray = {1,2,38,4,54,6,7,8,9,10};

for (int i = 0; i < myArray.length; i++) {
//your code goes here
}
NOTE: Your response should be just the missing logic--not the entire problem set.

How do I get fix the code to make it input 3 values and get the correct output

12.20 LAB: Driving costs - functions

Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))

Ex: If the input is:

20.0
3.1599

the output is:

1.58
7.90
63.20

Your program must define and call the following driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles.

Ex: If the function is called with:

50 20.0 3.1599

the function returns:

7.89975

def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon)

Your program should call the function three times to determine the gas cost for 10 miles, 50 miles, and 400 miles.
---------------------------------------------------
I need help for this part
Ex: If the function is called with:

50 20.0 3.1599

how do I get it to input the three to get the output of 7.89975?
-------------------------------------
My code:

# Define your function here.
def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon):
return (driven_miles/miles_per_gallon) * dollars_per_gallon

if __name__ == '__main__':
# Type your code here.

# Miles per gallon from input
miles_per_gallon = float(input())

#Dollars per gallon from input
dollars_per_gallon = float(input())


# Display the results as output

print('{:.2f}'.format(driving_cost(10, miles_per_gallon,dollars_per_gallon)))
print('{:.2f}'.format(driving_cost(50, miles_per_gallon,dollars_per_gallon)))
print('{:.2f}'.format(driving_cost(400, miles_per_gallon,dollars_per_gallon)))

Write a program that prompt the user to enter a bank balance. The balance entered by the user is read into a variable named balance. The program then prompts the user to enter the amount to be deposited. The amount entered by the user is read into a variable named deposit. The program that calculates the new balance, which is the present balance plus the deposit. The program then displays the new balance.
