Answer:
Option B  and  Option D 
are correct answers.
Explanation:
To view the invoice data on the related account records in sales force when invoices are stored in SAP we must:
- Create an External Object connected to an invoice table in SAP
 
            OR
- Connect to an O-Data Publisher Service for SAP databases.
 
SAP can be defined as Systems, Applications and Products. SAP is basically a software which has a backbone of SAP ERP (most advance Enterprise Resource Planing). SAP software helps to manage many business areas by providing powerful tools that include financial and logistic areas.

Answer:
def analyze_text(sentence):
    count = 0
    e_count = 0
    for s in sentence:
        s = s.lower()
        if s.isalpha():
            count += 1
        if s == "e":
            e_count += 1
    return "The text contains " + str(count) + " alphabetic characters, of which " + str(e_count) + " (" + str(e_count*100/count) + "%) are ‘e’."
Explanation:
Create a function called analyze_text takes a string, sentence
Initialize the count and e_count variables as 0
Create a for loop that iterates through the sentence
Inside the loop, convert all letters to lowercase using lower() function. Check each character. If a character is a letter, increment the count by 1. If a character is "e", increment the e_count by 1.
Return the count and e_count in required format
 
        
             
        
        
        
Complete Question:
Recall that with the CSMA/CD protocol, the adapter waits K. 512 bit times after a collision, where K is drawn randomly. a. For first collision, if K=100, how long does the adapter wait until sensing the channel again for a 1 Mbps broadcast channel? For a 10 Mbps broadcast channel?
Answer:
a) 51.2 msec.  b) 5.12 msec
Explanation:
If K=100, the time that the adapter must wait until sensing a channel after detecting a first collision, is given by the following expression:
The bit time, is just the inverse of the channel bandwidh, expressed in bits per second, so for the two instances posed by the question, we have:
a) BW  = 1 Mbps = 10⁶ bps
⇒ Tw = 100*512*(1/10⁶) bps = 51.2*10⁻³ sec. = 51.2 msec
b) BW = 10 Mbps = 10⁷ bps
⇒ Tw = 100*512*(1/10⁷) bps = 5.12*10⁻³ sec. = 5.12 msec
